HELP!!

I'm stuck here. Won't budge at all!
8 screws off, with the very front plate + 2 screws off, and it's stuck.

Tried "Blaster" plus a large wrench, but it won't come off.

Even thought of taking if off at the block, but it looks like those hex bolts might be easily stripped.

You'll be better off removing the pump from the block and then doing this =>

More than you are likely to ever want to know about OM61X piston vacuum pumps

Don't leave that there - I'll take it to bits!

Stretch,

Thanks so much for the link.
Exactly what I was looking for.

Happy to report the housing finally came off with much PB Blast and a chisel and a few hammer taps!

Stevo above stated:
"Be sure to check the end play on the timing device while the vp is off. I had almost 2.5 MMs, which took out the vp. I dont know what its spoz too be, less than 1mm I would think."

Is the timing device the cam follower???? Is it side to side play or longitudinal play????

The timing device is the gear with the rollercoaster cam on it. Excessive play (moves in and out) is a result of a worn thrust bearing and will trash the vacuum pump.

Here I am again, did this in 2017 and now again. this time am taking the whole pump off instead of just the housing.

At least I am getting better at it each time.

Bearings look perfect.

I couldn't find parts when needing a vacuum pump for the 84SD. Also, there were no pumps available from anyone but Mercedes. Rebuild kits NLA, Piersburg pumps NLA. Save your core in case you can use it to build the next one.
