There's a wear item called a 'spacer ring' that the lip of the front crank seal rides on. Anyone ever have to replace it? Looks hard to get out, no one seems to have tool 616 589 00 33 00 either. It's not in pieces yet, just trying to line up tools for the job (front crank seal replacement).

engine?

model?

I was able to pry my spacer out (617.85 engine) with two small screwdrivers. I had to use two at the same time, 180 degrees apart. Prying on one side at a time did not work.

Do tell! Which edge/corner did you pry on?

On the 617 engine, I was able to get behind the spacer at the 3 and 9 o'clock positions. The 616 might be different.

The spacer is a slide fit but the two short "half "dowel holes locating the balancer get burred and prevent it coming off easily. Dress them carefully with a with a small fine oil stone. As the oil seal sits about 3mm off-center the sleeve can be re-used if you turn it round the other way. Mark which way round when you remove it! An MB replacement is not cheap!!

I would recommend against reusing the spacer. Seals are not all created equal. That fact, combined with a minor deviation in seating depth, could put the new seal in the old wear area on the spacer.

The benz tool looks like a collet with a press screw. Bet you could get a female pipe thread tapped in an aluminum tube of appropriate size, and put 6 or 8 3/4" cuts in the end to make fingers. Whack it on, cross your fingers, pull it off. Might wiggle off for you if you bore a sleeve for a light press fit, ,and tap it on. Sounds like overkill based on this discussion tho. Thank you everyone.

how do you know this is a wear item?

Just curious

I have two grooved ones that wrecked front crank seals on my work bench.
It was not possible to flip and re-use, due to surface gouging during difficult removal.

Per the FSM, replace if worn. Makes complete sense- it's a sacrificial item. You get to groove a $10 ring with the seal instead of the crankshaft.

You're four times

www.kiva.org It's not like there's anything wrong with feeling good, is there?

I try.

I was simply stating a concern because I did not come across this information when I recently installed a polished crank. If I had known, I certainly would have replaced it... after reading this (and your informed response), I began to question what precautions I had taken.

sorry to offend

the more I think about it, actually, the more I recall having difficulty pulling the spacer beyond the crank nose. I wonder if I may have sacrificed the bearing like quality of the inner diameter.

ps - where in this thread was it indicated that a MB source decided this was a 'wear item'... just curious?
