Transmission Part# Help
 

Hi everyone,

​​​​​I'm seeking help trying to identify this part on the 722.6 transmission. I'm almost certain that it pertains to the oil pump assembly but not 100% certain. It is a coil spring O ring. It has been a few years since I disassembled my transmission to replace every O ring and seal. I've checked the complete transmission rebuild diagrams and can't seem to locate the part. I want to replace it due to a few kinks in the coils. Any and all help is greatly appreciated! Thank you!

Thanks Benzrider! I will try calling them tomorrow!

Love the stance of your '99 C43.

Looking in MB's Information Parts System, it could be part # A0169971448 (see diagram and part 15 attached)

Thanks DRBC,

Unfortunately part#15 in the diagram is the large rubber O ring that seals the oil pump. I've literally checked every part# and can't locate it. It is a complete circle metal coil spring that is exactly 3.5" in diameter.

Understood. Let me check further inside...

Searched high and low but didn't find something which looks like the part you are looking for. Sorry 😖

Thanks DRBC!

I appreciate all your help! I finally figured it out and thought that I'd share it with anyone that runs into the same problem. That part is actually inside of the front main seal. When I removed the front main seal a few years ago, I recall that the seal had separated. The part in question had fallen on to my work table and I kept it, thinking it was important. This part is inside every new front main seal. I racked my brain over this part for the past 3 months. I suppose the moral of the story is to bag, label and take pics of all parts before and after removing them. 👍

Damn never thought of that, but now you mention it its obvious :D

That isn't an individual seal. It's a spring that fits inside of a lip seal. Only 2 lip seals from memory are the input shaft seal and the output shaft seal. Based on it's size it'll be the output shaft seal that is missing the spring.
Buy a new seal and the spring is already attached.

Thanks Ausmbtech! I figured that out after a closer look at the front main seal. I recalled that the seal separated upon removing it and did not notice the spring pop out until I found it on my workbench. I completely forgot that you're an mbtech. next time I'm stumped, I'll contact you first! Much appreciated!
