I have a classic bmw motorcycle that uses these insanely expensive mini tapered roller bearings for the paralever final drive. these are driveshaft bikes. no chains. in the late 80s they went from one pivot at the swingarm to dual pivots. one added at the final drive. these don't move very much...

UPDATE!!! I spaced out after i fixed the problem.. so it was the oil pressure relief valve. it was stuck in a compression. i could slam it on a table and the spring would pop back.. MBZ dealer laughed at me. found one NOS from a old parts guy in so-cal. $50 and 2 days later problem fixed...

i bought those before making my first post. i dont see a issue im having a issue finding a relief valve. is it even possible to get one new?

ok guys. i think i found the problem. stuck/broken oil pressure relief valve. it feels like its broken. it will pop and give after pushing on it. you have the tap it on a solid surface to get the plunger to return

thanks for your post and your charts. for the price and the miles i put on cars/trucks i run 15w-40 in all my old diesels. i have a 91 dodge cummins with 400k on the original engine. i bought the truck from the original owner. delo 15-40 its whole life. only big issue was one headgasket...

i have not changed the oil yet. i dont think it will make much difference as the previous owner has already changed it. i will check everything out when i drop the pan

no i am not 100% on the gauge. in my long ownership of these cars i have only had 1 oil pressure gauge fail and it still worked.. just leaked out of the oil line. i will put a mechanical gauge on it to check pressure. also, i dont see how 0-20w would clean it. as diesel oil has higher levels...

hello all. i just bought a 83 mercedes 300d. OM617.912 non turbo... story is 2 owners ago decided if the oil would work in his honda hybrid it would work in the benz.. 0-20w is what i was told. previous owner changed it to 15-40w ASAP. oil pressure at idle is a bit low at .3-.5 bar when hot...
