The original style has a smooth lid, cover, whatever you wish to call it on the front (front of car) side. The later style has the cover bolted on and the bolt heads protrude from the cover/front side.

Are w123 pumps the same as 124's?

No, entirely different. The 123 (OM617) pumps are about 3 times larger and can be rebuilt, and I've yet to hear of one of those pumps falling apart internally.

I had one of the "later" W123, piston type pumps come apart due too lateral movement of the timing device caused by a worn bushing. Caught it before it destroyed the engine.

"Lifes too short to drive a boring car"

Years ago I had a W115 VP that internally grenaded, but mercifully it didn't take out the engine.

I have a rebuilt Pierburg. It has the plastic encased bearings. I don't know the build date. There was a post somewhere that had the progression of part numbers for the Pierburg. I think mine ends in 77.

My timing device is of the old style. It has a little galling but I'm tapped out now for replacement parts on the car.

In a past thread I ask people what they thought caused the VP failure.

What in particular causes vacuum pump failure?

Another Thread concerning Timing Chain breakage;some of the member felt the Vacuum Pump had failed a part fell into the timing Chain. I believe most 617 engines.
Who has or knows someone that has experienced a timing chain breakage/failure?

If anyone's still listening, could you tell me if this pump is Ok. It's not the pierburg as far as I can tell, but maybe it is just unbranded or something. I can't tell, looks the same as the new pumps to me (for a 92 300D 2.5 which had the new style)



It's part #0002303165, I just don't know if it's decent quality. I've only seen Hella and Pierburg as manufacturers, and this one doesn't have the sticker they have (both look identical btw and they both have the PIerburg sticker on them. Weird).

THis one comes wtih the gasket, and it is the dam style gasket right?

I bet it's the cheap Chinese pump sold on eBay, probably from BATP. I would have sworn there was a guy who bought one of these because it was "cheap", and it failed within a year, but I can't locate that thread. Here's a little more information on the BATP pump:

Strange OM603 vacuum pump brand

I wouldn't put one on my car. FYI, the lowest price I know of for a Pierburg pump, actually a genuine Mercdes-Benz dealership pump, is from Parts.com ($248 plus S&H, which may be ~$25, but still worth it). ElAuto is $299, ********* is $312, ******** wants $329, Bimby is $340, FastLane is $352, and ******** is $393 (!). MB dealership list price is $360, btw.

Yes, that is the dam-style gasket.

I nought an even cheaper pump (it was £35 in the UK, about $70) that had standard bolts on the front cover rather than torx bolts. The first one I got blew up, put a big dent in its cover but luckily didnt take out the engine, only my power brakes going 80mph, eeek.

The second one I've had for 5 months now, and is still going strong, pulls a very strong vacuum. Only problem is the head sheared off the bottom bolt, so it now leaks a little bit of oil. One day I may take it out and try to fix that, or just replace the dam gasket with my old non-dam, as I think that should fix it.

Tombance,

Do you get nasty little e-mails from your engine about endangering it's
Timing Chain?
