I did search and didn't come up with anything. I was wondering what the AA stands for in the picture?

AdvanceAdapter?

Yup AA does the casting for Marlin

Thanks Lil Swamper and White Trash. Should have known but was hoping it was for "All American".

From the beginning, John Partridge [the founder of Advance Adapter] had my name put in the mold next to AA nameplate. Back then, Advance Adapter was sending all their Toyota customers to me because they did not have any salesmen that could figure out the differance in the t-case styles even though I drove to Paso Robles and taught them by self.
This continued until AA begin to realize that going slow with a Marlin Crawler was beginning to be quite popular.

They also begin to realize that they were sending a lot of customers to me and losing the sales as well.

AA then begin to sell the adapters themselves and started pushing the plates to other offroad companies.

I complained because any so called "offroad company" could sell my adapter, so I requested that my name be removed from the mold.

Because the same casting is used on the weaker than stock AA narrow bearing design, and my maximum duty double wide bearing as well, my name was removed from all the castings.

Its nice to have things with your name on it...all I have so far are tickets and work write ups

Thank you `O Grand Exalted Marlin Sir for taking the time to explain this to me

. How can I tell if I have your bearings or not?

WHITE_TRASH · « **Reply #7 on:** Aug 23, 2004, 04:42:15 PM »

How wide is the bearing? If it is only about 1" wide then its a Mco5 or advance unit. If the bearing is about 2" wide its a late style Mco7.

#$@*%

I took the cases down to the shop today along with a bunch of other parts. My engine guy wanted to check out the cases before putting them back together. The top bearing is pretty deep. Oh }{ell... with my lightweight junk it might not make any difference.

Now I feel like a tool. It has 9 spherical bearings, its a Mco5. Mco7's have 32 spherical bearings.

White_Trash,

Your volume of knowledge never ceases to astound me!! You are an asset to the forum! ...I meant that in a good way

WHITE_TRASH · « **Reply #12 on:** Aug 23, 2004, 05:58:55 PM »

Im just trying to keep up with Marlin.

Marlin · « **Reply #13 on:** Aug 23, 2004, 08:12:09 PM »

Toyhatsu, you appear to have #539 a early MC 07 $Beer Chug\'n$ We have now sold over 2,100 plus

Is the mainshaft bearing retained by a large offset triangle shaped plate with 3 bolts?
From your photos, I can see my added oil feed groove and the open face of the mainshaft bearing.

All MC 07's use a double roll, maxium ball bearing that uses 32 total bearings.

However, way back then, when I first designed and sold the MC 07, I quickly depleted the United States supply of the maxium double row bearing [there are no U.S. manufactures that make the maxium style], and due to overwhelming sales, we were forced for a short time to supply the plates with a standard double row bearing.

We now order bearings months ahead of time at 500 per order.

Please post a pic of the front side of the adapter plate.

Dang, Marlin you've gotta keep me up to date on all the stuff you guys have done.

I had no idea you had a lower count double bearing.

Marlin · « **Reply #15 on:** Aug 23, 2004, 08:39:21 PM »

This was only done for a short time, untill I was able to get an air shipment of max bearings.

I would guess there are around 100 early Crawlers with the standard double wide bearing.
We have had a perfect service record with all of our double wide bearings

[Just as long as there is oil in the unit]

I am starting to think about selling my crawler and get one of those nice strong ones from you guys

SWAMPER · « **Reply #18 on:** Aug 23, 2004, 08:50:44 PM »

Hats of to you dear Sir

`O Grand Exalted Marlin Sir ,

I stopped by the garage after work and he had the cases put back together. The reason that I pulled it apart was because it was easier to move around by myself and it was clearly leaking gear oil between the adapter and the rear case. I found that the nuts to the adapter studs weren't torqued very tight and the paper gasket was shot. All of the bearings "felt" real good and as you can tell by the pictures it seems to be in good condition. I removed the interlock pin this last weekend on the living room floor of my apartment. No garage. Your twin stick is really a work of art!!! I kind of hate to put the boot over it. I really hope that the 3RZfe, W56 and your crawler will fit in my little truck.

I am sorry that I won't be able to get a picture of the front of the adapter. It is my opinion that the front and rear cases will fail before your adapter! I was looking closely at the workmanship of what I could see and was very impressed. I don't know how old it is but I have the utmost faith in it because you built it

Thank you very much for taking the time to answer my questions.

I am assuming that this is the right pin...

Marlin · « **Reply #20 on:** Aug 25, 2004, 11:13:33 PM »

Thanks for the kind words

You removed the proper interlock pin.

You have a MC 07 Marlin Crawler with the double bearing.
