Re: [MBZ] OM617 Vacuum Pump
Well, the kid was complaining of no brakes and car won't shut off. I fire it up and it is making an awful injector nailing noise, but louder. I pull the line off the vacuum pump, and yep, no vacuum. I got it apart today and the yoke that holds the bearing that rides on the eccentric has failed. My question is this. I have heard that the injection timing advance device can fail also. Is there any easy way to tell if it has failed? The springs are intact and nothing is loose. Rick Sent from my iPhone the OM621 book had a section on testing the timer. Pretty much if the timer is intact, it is good. I have never seen one fail in the US. IF they fail, it is probably over 500k miles and/or poor lubrication/never changing oil etc. My 400k to 500k mile 190Dc never had a failure of the IP advance. ___ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
Re: [MBZ] OM617 Vacuum Pump
Thanks for the link and writeup, Rich. That should be very, very helpful... as soon as I order the second half of the rebuild kit. It's not at all obvious, lacking the manual writeup, as I was when I ordered, that *both* are needed for a full rebuild. I'd assumed they were for different variants of the pump, and only ordered the valve, not the diaphragm. D'oh! Stuart S. 1976 300D w115, with increasingly fewer original engine parts.

Aha. So now we know. Go to Kaleb's for parts and you and your SDL are never seen again... Bates Benz Parts, as it were. So that's where that stuff he puts on eBay comes from.

Re: [MBZ] OM617 Vacuum pump
Stuart The only thing I can think of is that there is a main line check valve that isn't included in the rebuild kit. It is the valve located at the vacuum side of the pump. You might as well replace that while you are in there. I'm going to send article directly to you on rebuilding because it will only get stripped on this site. Dennis Perkins 84 300SD Hi, list! Yesterday, driving home, I heard an awful noise coming from the front of my car (w115 300D, OM617.910). As I pulled over, I noticed my power brakes were no longer power, and the car didn't shut off when I turned the key. Once I opened the hood, the reason was clear - the vacuum pump was no longer attached to the engine, and was hanging in place on its hoses, and the noise was it rattling against the fan (fortunately, it caused no significant damage to the fan, though there are a few nice chips out of one of the blades from one of the screw or bolt caps on the pump casing. Anyway, having ascertained that there doesn't appear to be anything missing from the inside of the pump (which looks dead simple, thoroughly attached and just like the new one on rusty's site), I've ordered a rebuild kit (pre-emptively, since it's already off) and a new gasket. I have a few questions, though: 1). Is there anything unusual or unobvious about putting it back on or rebuilding it? It looks like it ought to be simple, but there's nothing in the manual about it, so I thought I'd ask if there are any un-obvious snags. Do I have to lubricate or seal anything in the pump, or the new rubber bit for the rebuild? 2) Am I correct in thinking I just need to bolt it on with the new gasket? No sealant is necessary, yes? 3) What kind of bolts do I need? (Hoping someone knows, somehow!) Since mine *fell off*, I don't have any, and Rusty's people say MB doesn't carry those bolts anymore, so I'm going to have to buy some from a hardware store. If anyone has one lying around for some reason, the size and pitch and length would be very, very, very useful. Thanks a bunch in advance, Stuart S. 1976 300D w115 (OM617.910)
Re: [MBZ] OM617 Vacuum Pump
Mine failed after only two months of being rebuilt. Rusty sent me new parts and I'm going to tear into it tomorrow. It will be interesting to see what failed.

Re: [MBZ] OM617 Vacuum Pump
What came loose is the six bolts that hold the vacuum pump on to the engine block! All of them fell off, presumeably after being worked loose - for all I know, when I got the car two years and change ago, some of them might have already been gone; it's not something you normally check.
