Topic: Massive Marlin Crawler parts comparison!!!

[potter85]

I will never understand why people say that other competitors parts are cheaper than marlins and the fact is that everything they do there is fully backed and everyone is so helpful. The fact is that by spending a little more you will have a far superior product. I had a sset of 3rds set up there with 4 88s and detroits and someone from the company drove to paso robles in his wifes nice car with my parts in the trunk and meet me at bubbas bar ba que. And i am pretty sure his wife was pregnant and not to mention it was a sat.... PRETTY SURE NO OTHER COMPANY WILL DO THIS. thanks so muchs guys keep up the amazing work

[REG535]

keep up the good work marlin and MC crew. I need to start ordering from MC only and only MC from now on!  

[axled89]

that's funny cuz that is what i was replying with.   it is true.     here's a turtle p.

[whitey1]

would you rather be a worm or a turtle?

[blackdiamond]

would you rather be a worm or a turtle?

I'm a big Marlin fan, but after having some issues with my turtle I ended up being a worm.  I ran out of time to wait so my new turtle ended up in a friends truck and is doing great.

[86rustbucket]

would you rather be a worm or a turtle?

or a trail queer?

[Raybicon]

I like Inchworm it is a good company and they make good products. Plus it is 5 mins from my house so you got to like your local company.

[Raybicon]

Why is their no more 5:0:1 gears being sold?

[Raybicon]

in my first post I'm just talking about adapters. not gears or anything else. I just wanted 2 clear that up.

[REG535]

5.0:1 was made by aa and is discountend

[88sr5runner]

guessing he ment to say discontinued by aa and not discountend

[kneedownnate]

And wasn't a true 5:1 anyway. 

[NorCalToy]

And wasn't a true 5:1 anyway. 

I think it came out a 4.96:1 and was made somewhat weaker by adding another tooth to the 4.7 gearset.

[Raybicon]

 Tomarrow I'm going over to Inchworm and getting my boxes changed. (since they havent finished mine yet. I deleted some of the drunk words in this post-It was cinco!

[<MIKE>]

Hey how come a complete dual case with tacoma chain case is 1449 and just the crawl box for a taco case is 1695?

[kneedownnate]

Now I've read all the posts and I'm pissed I didn't read it earlier. Tomarrow I'm going over to Inchworm and getting my boxes changed. (since they havent finished mine yet. I'm going to have a little talk with Jim. I told him I wanted all the best strongest parts, and obviously I'm not getting that and I feel like he lied to me. I'll let you guys know what happens tomarrow night.

I wouldn't do that if I were you.  Any business is going to tell you they have the best of the best.  Some are right, some are conjecturing and some are knowingly lying to you.  I can't speak to the quality of inchworm stuff since I haven't seen it first hand, but it does look nice, and Marlin sells their lefty so they must agree to an extent.

[Raybicon]

I've known Jim for a while I met him 5 years ago. I like him because he is a nice guy and gives me deals. Last year he came to my house and traded me some of my parts towards credit on a sas kit. I know some of what he sells to Marlin and, what Marlin sells to him.  He has $2,500 of my money for products that I don't have yet so if I want something changed I will have it changed.  I need 2 find out what product is really better you know.

[gtoyonrocks]

There is some awesome info on here. This is great... Thanks for everyones inputs.

[realcamotoy]

 :thumbs:Good read , and good 8) info,wasnt sure why i liked Marlin, but now i know why.

[2 feathers]

Thanks everyone for all the great information. I ordered a marlin clocked 4.7 dual case complete setup for my 88 reg cab project.

[BigMike]

Thanks for the order 2 feathers and for the continued compliments on Marlin's design

Here are the highlights to our XD updates to our Dual Case Adapter Kit:



1. Double Roller Maximum Capacity Main Shaft Bearing

The key ingredient in the reliability and longevity of the dual case adapter is how the coupler is supported. Knowing this important fact, Marlin incorporated a large, double roller bearing into his first dual case adapter in 1994. The manufacturer at the time refused to use such a large bearing instead opting for a cheap, in-house part. Finally in 1997, Marlin had enough stripped out couplers to finally convince his manufacturer to use a double roller bearing.
This was a critical turning point in the dual case adapter world. The double roller bearing has been proven to be over 100 times more reliable than a single roller bearing. The double roller bearing is so successful in fact, that it is used in our MC07, MC08, MC09, MC10, MC11, and MC12 dual case adapters.

• Proven to be over 100 times more reliable than a single roller bearing design.
• 158% stronger than competitor's single roller bearing.
• 256% less load per ball due to its high 32-ball count.
• The only dual case adapter in the world with a double roller bearing.
• The only dual case adapter in the world with a maximum capacity bearing.

How many balls do you have?


2. Chromoly Coupler

You read that right: The XD MC07 Crawler comes with a Chromoly Coupler. This is Xtreme Duty, this is Marlin Crawler.

• Chromoly Coupler adds extra strength where it is needed the most
• Stronger material provides exceptional spline wear characteristics

3. Oversized Heavy Duty Cage Bearing

This is another Marlin Crawler Xtreme Duty exclusive feature: Larger, higher load rating, and machined lower cage bearing. We have seen some lower cage bearings overheat in extreme conditions, such as heavy trail breaking in deep snow or mud. You might think the snow would keep the case cooler, but what happens is the snow melts around the drivetrain and then freezes into ice creating an insulating layer around the transfer cases. This prevents any air flow around the cases and, in turn, the gear oil temperature begins to rise. The Xtreme Duty Crawlers feature this MASSIVE lower cage bearing to combat this issue.

• Heavy Duty Machined Race (instead of stamped steel)
• 84% more massive.
• 52% stronger load rating.
• 42% larger rollers.
• 13% higher speed rating (not applicable in terms of crawling, but this shows it's superior heat dissipation).

4. Radiused Coupler for increased pocket bearing oiling

The input pocket bearing is housed within the coupler. Because this pocket bearing is above the gear oil fill level, it is important to get the right amount of oil to the pocket bearing. Our 4.70:1 Xtreme Duty low speed gear features an innovative oil pump system, however 4.70:1 gears are generally not used in a Crawl Box. For this reason, we have designed our Xtreme Duty coupler to encourage oil flow through the pocket bearing while at the same time trimming off fat.

• Increased pocket bearing oiling.
• 13% lighter coupler.
• Lighter coupler enables improved bearing support.

5. Heavy Duty Plate Webbing

The Xtreme Duty adapter plate lives up to it's name with full flange webbing. The previous designs stopped short of each flange, but not the Xtreme Duty design.

• More strength to hold the two flanges together.
• Improved plate rigidity for extreme operating conditions.

6. Thrust Washer Lock System

This is VERY important and often overlooked: Every Toyota thrust-washer has a detent ball lock system. Every main shaft in every transmission Toyota has ever built has a locked thrust washer-to-shaft system: All L-series, all G-series, all W-series, all R-series. Additionally, every transfer case they have made uses a thrust washer-to-shaft lock system including all 4-cylinder and 4-cylinder Turbo gear drive cases, and all chain drive cases including those found in Tacomas, 4Runners, T100s, FJ-Cruisers, and Tundras. Heat treated same-metals should NEVER be allowed to wear against one another.

• Prevents unnecessary wear.
• Reduces the amount of metal debris in your gear oil.
• Prevents unnecessary heating of thrust washer and coupler.
• Extends the life of the coupler, thrust washer, gear oil, gears, and bearings.

7. Shelf Oil Passages

Our adapter plates are designed with 6 oil passages between the transfer case and the Crawl Box. The upper two oil passages are above the oil fill level so only turbulent oil is able to transfer through these passages. Because of this, we've designed our Xtreme Duty Crawler plates to include shelves to "catch" and drain this oil right into the upper oil passages.
Our previous design lacked shelves and therefore relied on vehicle acceleration in order for gear oil to pass beyond the main bearing. Unlike other adapters, the Xtreme Duty adapter transfers oil under cruising conditions. This never before seen feature is only available with a Marlin Crawler.

• Shelves catch and direct turbulent oil to flow passages.
• Transfers oil under cruising conditions, a never before seen feature.
• With a total of 6 flow passages, the Xtreme Duty adapter flows the most amount of oil.

8. Multi-bolt Retention System

When we invented the multi-bolt retention system back in 1999, we knew it would be a world class feature. That is why 7 of our dual case adapter kits use this innovative Marlin Crawler feature. Some competitors try to emulate Marlin Crawler, but the fact is Marlin Crawler has been using this design for more than a decade.
We always configure our bolt retention system with equal bolt spacing. This results in an even load distribution. This is very important because bolts that do not experience a load may easily vibrate loose resulting in catastrophic failure! Additionally, using fewer bolts results in less chance for failure.
Technically speaking, 1 bolt would suffice since the tensile strength of the grade 12.9 bolt far exceeds the axial loading forces of the low speed gear, but we wanted to evenly spread the load across the snap ring while providing an esthetically appealing final product. Our design was changed from a 3-bolt system to a 4-bolt system because the larger Xtreme Duty lower cage bearing prevented an equal 120-degree 3-bolt offset pattern, but allowed for a 4-bolt 90-degree offset pattern. The rest is history.

• Four equally spaced bolts result in an even load distribution.
• Fewer bolts that are evenly loaded result in a much lower chance of one coming loose!
• Marlin Crawler invented the multi-bolt retention system in 1999.
• Over a decade of experience in 7 different adapter kits.
• 1 bolt would be sufficient, but multi-bolts provide an appealing final touch.

9. Proper JIS Heavy Duty Fasteners

Marlin Crawler has used Japanese Industrial Standard (JIS) hardware since 1994 and will continue to do so. Your Toyota truck doesn't have any 13mm, 15mm, 1/2in, 5/8in, or 11/16in bolts so why should a dual case adapter have non-Toyota hardware? You drive a Toyota, you only carry tools to service your Toyota. Marlin Crawler takes great pride in using the proper hardware for the job. Additionally, you won't see us using any nylon locking nuts because it is common for the nut to lock to the stud in such a manner that the stud gets extracted with the nut. And since the adapter flanges are so close to one another, you can't get the nut off of the stud in order to get the housing off of the adapter plate! Sheesh! Also, the nylon cracks and degrades over time causing the nut to simply unthread. Toyota uses flat &amp; lock washer combinations all over your truck so it is only natural for Marlin Crawler to use the same. Don't get "screwed" with inferior mounting hardware!

• Using JIS compliant hardware since 1994.
• Flat &amp; Lock Washer combo is standard Toyota practice that far outlasts locking nuts.
• Clearance around nuts provide access to nuts using a box-ended wrench (see image below).
• Keep your non-Toyota tools at home!

Please consider the below image of the JIS fasteners installed into a Marlin Crawler Crawl Box. A small 14mm box-ended wrench is able to fit between the nuts for proper disassembly. The nuts are also able to fully unthread from each stud. This is not possible if non-Toyota 11/16in nuts are used. Furthermore, have you ever tried getting a huge 17mm or 11/16in hand wrench up between your transfer case and truck body? It's a nightmare! It's these sort of smart and friendly features our customers appreciate.


10. CAD Optimized Light Weight Adapter Cut Out

Using the latest in computer software, we were able to reduce the weight of the adapter plate by an incredible 25% without sacrificing any strength! This also increases the oil capacity of our Crawl Box because the material we removed provides extra space for more gear oil. Additionally, the adapter cut out allows for other advanced features such as the shelved oil passages.

• CAD optimized material removal yielded a 25% lighter product.
• Largest Oil Capacity on the market. More oil = cooler running = longer bearing life.
• Supports advanced adapter features such as shelved oil passages not found anywhere else.

11. Unique Margasket

We have been providing our very own Margaskets for over half a decade now. These gaskets are unique due to their universal nature. You don't have to second guess which gasket to use with which donor transfer case, we've taken all of the guess work out of the install process. Marlin Crawler customers appreciate the attention to detail of our products.

• Universal Margasket fits any donor case no matter the shift style or year.
• Removes all the guess work of which gasket to use with which donor case.

12. EcoSeal Transmission Output Seal

The EcoSeal needs little introduction. This heavy duty replacement transmission output seal has a metal flanged lip to ensure a full installation into your transmission's tail-housing. This prevents installing the seal sideways/crooked, a severe installation error that reduces the life expectancy of the seal as well as the sealing effectiveness. The EcoSeal eliminates installation errors ensuring the job is done right the first time. A transmission rebuild is expensive; keep your transmission and transfer case gear oil separated.

• EcoSeal eliminates installation errors.
• Longer life expectancy and improved sealing.
• Marlin Crawler has been including complementary transmission output seals since 1994.

Conclusion
After examining the most feature rich and technologically advanced Toyota RF1A dual case adapter kit in the world, we are certain you will agree that the new Marlin Crawler Xtreme Duty MC07 is on a completely different level far, far above all the rest. There simply is no comparing a Marlin Crawler with any other.

No problem mike. when you compare the data that marlin openly supplies its a no brainer. Im a self proclaimed montana newbe looking for information instead of influence. P.S. my ultimate setup came yesterday and thanks for the quality of the packaging everything looks killer. keep up the great quality and customer service. Tommy 2 feathers

[BigMike]

Awesome, glad to help you with your project Tommy! I'll never go wheeling again without my Ultimate!!

[REG535]

The marlin crawler turtle shift knob is awesome too. Great quality for only 10 bucks. Cant wait to order more.

Looks like this thread is pretty old and has a bunch of great comparisons on it, but not the comparison I was hoping to see. Maybe the info is in here and I just need to dig deeper...? I recently bought a new rock rig and am in the process of building her up! My previous rig had tons of MC parts that were great and I never had any failures. I've heard that the TG stuff out there is basically an exact copy of the MC stuff. I need a new dual case adapter and was offered a really sweet deal on a TG adapter. (sorry Marlin) I'm not rich by any means so I almost bought it when a buddy said they are way different from a quality perspective. I was told that the TG stuff is made in China with far inferior metals. Is this true or are they exact copies??

[OOPS]

I do not know where TG's stuff is made or the materials, but I know where Marlins stuff is made and there is a whole lot of R&D that goes into his products. It is a no-brainer for me, it would be Marlin, always has been and always will be. My dual set-up has been in my rig since 99 and I have never had a problem and mine is the old skool stuff!! That is MHO!!!!

You will get people here that will tell you that TG's stuff is made in china but there is nothing factual to back it up.

Marlins adapters are worlds better than trail gear. There is no comparison. The dual row bearings alone make the price difference moot. Not to mention the quality and r&d that actually went into the marlin design.

Trail gear makes things that will work. Some of their stuff is fine. There is def better options if you have the need or desire tho.
