Marlin Crawler Formula Toyota Buildup

[Marketing]

The steering box comes from a 64-76 GM, I am not sure about the body style but Andy thinks it's a Monty Carlo. We received a rebuilt unit from Cardone, part# 27-6537. It cost us $226 to our door. We also ordered a power steering pump for a 78 Chevy Truck (V8-350 5.7L). The part number for the pump is Cardone #20-6800. Their web site is www.cardone.com  I don't think they sell direct, but you can buy their parts at many local auto parts stores.
There are lots of different steering boxes that look similar. This is the one to get because it's got the strongest housing. Notice the cast gussets between the bolts. Other models do not have these ribs.

I hear Marlin the Dog is ccrraazzyy and that he chases ambers coming from the fire pit!

[KYOTA]

Looks good, coming right along. You'll love the PRP seats 8)

We dropped the the seats in today and I sat in them to figure our where the seats need to go. They are nice and comfy.

A slight bit off subject. Who can make custom length rear axle shafts to fit a custom rear housing design?

[Marketing]

The 38 X 12.50 TSL Swampers came in! Soon we will do a little cutting on these with a hot knife for extra traction.


On to the transfer case...
Rocky built up a dual Ultimate Crawler unit using our new MC08-R10 dual adapter. This adapter rotates the rear case 10 degrees to the left. This rotation creates a flat bottom under the tcase.


Normally the bottom of a Toyota tcase has the 4wd section hanging down below the reduction housings. With the rotated adapter, the 4wd section is lifted up 1 3/16, level with the reduction housings.


Another view along the bottom


The front case has factory 2.28, 21 spline gears, the rear has 23 spline, 4.7 gears.

Very good choice on the tires.  I ran those for years and I loved every minute of them.

Chris -

I'm trying to figure out the Tacoma gear deal.  Would you mind answering a few questions for me?

The Tacoma gears can be used in ANY of the 8" older toy 3rds?  Just Turbo?  Just V6? 
Can you get the 30spline pinion flanges?

Your build is well-documented and well appreciated.

For info on Tacoma gears, call us at the shop and ask for Rocky, he does our gear installs.

Thanx Chris!

[toy87]

great build up, its great to see what happens in every part of the project, can't wait to see the finished project, keep up the good work.

Yes marlin the dog goes crazy around fire...I witnessed it myself last summer down at the hammers.  That was the time Chris introduced me to Mickey bombs.  If you think Marlin the dog goes crazy around fire, wait till you see him when one of those goes off

[Marketing]

Mickey bombs are cool!

[reklund5]

  

Back to work on the formulatoy!!!   

[toyhatsu]

My kind of recreation!  Work hard and play hard.  Would you please explain what a Mickey bomb is?

[FATB0Y]

Would you please explain what a Mickey bomb is?

[donkeykong]

Take an empty mickey bottle or Sobe bottle works to.  But isnt as fun to drink.  Fill it will gas...HEHE...can you see where this is going.  Put a very very tiny pin hole in the center of the cap...it has to be so small you can barely see light throught it.  Slide the bottle in to the fire.  They used a 2x4 to slide it in, trust me you dont want to get to close to the fire with a bottle of gas in your hand.  after the gas starts to boil in the bottle it starts to steam out the hole, when the pressure is to great for the cap to hold....BOOOOOOM.  sit back and watch the people scatter

P.S. Sorry for getting so far off topic...Back to the Formula

[FATB0Y]

Oh............

Where did you guys get your PRP seats from? Did you get the 2" wider or taller version or the standard seats?

[MidgetMike]

How's the formula comming  

[Marketing]

We pickup the Champion 15" X 8" beadlocked wheels tomorrow. Tire groover came in so if I am able to use my left hand this weekend, I'll be putting the tires on the wheels and grooving them. Tomorrow I am going in for surgery on my left hand and I may not regain full use of it for two weeks, so I'll see how I feel.

While building the motor we encountered problems with the crankshaft. There was either a problem with the machining work or the center cap was changed after the machining was done. When we tested crank drag, we found the crank was binding. The crank was removed, everything was measured and a problem was found in the center main bearing cap. It took a couple days to remachine this cap and resolve the binding. After repairing the problem, plastigauge was used to verify proper clearances were restored. The drag of the crank is now correct.

So the block is now assembled and ready. Next will be head porting and valve job. After the head is installed, the motor, trans, tcase will be lifted in place and engine mount fabrication can begin.

I got them directly from PRP at:

http://www.prpseats.com/

We choose the standard ones. If we choose the wider ones we would have clearance problems between the seats and the transfer case. As it is the seats will be right on top of the case. To run wider seats we woudl have had to raise the seats up, or drop the transfer case down. 

[BLACKDOG]

Hey Chris, I was just reading back through the build and I was reading about plating on the diffs to gain ground clearance.  You mentioned taking out the bottom two studs and replacing them with bolts to act as drain plugs.  Is this possible to do on a standard diff??  I dont have a drainplug on my 91 V6 and I would like to put one in?  Is this a feasible option, or would it be better to just go with drilling a tapping a hole and installing a drainplug myself??

[Marketing]

Yes, it's easy to use studs. I have seen a lot of drain plugs drop out on the trail. I don't like having them on a trail rig.

Each time your reinstall the bolts, use some fresh silicon on the bolt to seal it up.

[BLACKDOG]

so what do i do, just hammer out the stud, or do  have to cut it off and drill a hole??
