I have my Canadian deuce manual at work. If we are open today (the blizzard just ended a coupel hours ago) I'll look up the NSN for those O rings. They are good for searching for sources, along with alternate part numbers.

I have NOS oil coolers for Chaffee G200-56-08479/GM 8508471 @$120. ... Brian

The cooler number is the same as the G749 deuce.

From the parts manual, the seals are as follows:

#14 Retainer GM hydramatic pn 8602482 NSN 5330-00-534-2364
#15 Packing Preformed GM Hydramatic pn 8602366 NSN5330-00-534-2366
#16 Washer non-metallic GM Hydramatic pn 8606463 NSN 5330-00-291-8947

Rob, this is the part I like least about working on these dinosaurs, finding parts.
Anyway, I found an M135 manual that gives part numbers for these coolers. I don't need the retainer, 5342364 (that's a solid steel ring), but I need the oil cooler mounting gasket 2918947 you listed, (which I could make out of sheet material if I have to), and I definitely need the shaped packing ring, 5342366 you also listed.

I've searched on these parts numbers and got a bunch of aerospace suppliers, which sounds expensive, but there must be somebody selling them for deuces. Anyone have any suggestions?

Thanks,
Malcolm

Here's a video of the front servo, which clamps the front band around the front drum, being tested with air. This is my first tranny rebuild and it's neat the way you can test various components with shop air.

Not just expensive, but likely fruitless. They list every NSN under the sun, but don't actually have anything. Most of them are more of an expensive ebay for guys who buy up surplus parts and want to get decent money for what would otherwise be useless parts, often re-selling the same parts to the governments.

I think your best bet would be to find what company was rebuilding the M135 transmissions in the US for the collectors. Query the guys on steelsoldiers.com in the old deuce section....they will steer you in the right direction.

So again, if you have not actually made the call...phone Brian Asbury for rebuilt trany parts he may still have some units left.

Brian, definitely interested. I'll get Ken Lee to give you a call.
