Re: [MBZ] OM617 motor mounts
It’s a personal preference, but I prefer to do one side at a time rather than both. I think it’s easier to get things lined up when you do one at a time, as the side that’s still anchored serves as a reference point. I loosen everything with the engine in place, then remove the fasteners on one side, raise the engine enough to remove the mount, put the new mount in place, then carefully lower the engine to get everything lined up. I’ll use a drift or piece of rod stock to line the holes in the chassis up with the holes in the mount. Lather, rinse, repeat for the other side. For what it’s worth, these older mounts are a real joy to do compared with something like a W163 (ML) where you have to get at them from the side via the wheel well. -D > On Aug 14, 2021, at 8:09 PM, Allan Streib via Mercedes > wrote: > > Thanks.

Thanks. Oil lines are good for now. I did the transmission mount earlier, along with flex couplings. I remember the allen head bolts being a bit fiddly on the W123 when I did it.

Re: [MBZ] OM617 motor mounts
My big tip: Be sure you have the right torque values for all the fasteners. My '85 wagon was non-turbo, but I mistakenly used the turbo engine procedure and the torque spec is far higher. I twisted off a fastener, had to order a new one from MB. Took a few days to get it. I think I was able to use a hardware store bolt for the interim and keep the car on the road. - Max Charleston SC On Sat, Aug 14, 2021 at 7:09 PM Rick Knoble via Mercedes < mercedes@okiebenz.com> wrote: > I was going to do a write up years ago.

Re: [MBZ] OM617 motor mounts
If all goes well, I think they are fairly quick, maybe an hour per side.

When I was a kid, I always liked to tinker with stuff, take stuff apart. Maybe 5th grade age or so I took apart the lawn mower. Dad wasn't really happy but told me to put it back together. Which I did, and it didn't run. Went to the library, got a book on Tecumseh engines, learned what timing marks on gears were about, and got it back together correctly. And it ran fine for years after that.

Re: [MBZ] OM617 motor mounts
Prices have gone down on these items as I recall they used to be a lot more expensive. It must be horribly frustrating to have to train people with limited skills, Rick. People, especially kids, don’t seem to tinker much any more. I think about the stuff I did as a kid that prepared me for being a mechanic, all more or less foundational stuff. -D > On Jul 14, 2021, at 3:51 PM, Rick Knoble via Mercedes > wrote: > >> I'd probably replace them rather than have to go back later and essentially >> do the labor twice. > > In my line of work I frequently train *new* apprentices. > Some of these guys (and gals now too) have to be taught > Lefty loosey, righty tighty.

Re: [MBZ] OM617 motor mounts
The "kit" is listing at $81 and the shock at $54, assuming those are the right parts. That's for one side. I guess not pocket change but still cheap enough that I'd probably replace them rather than have to go back later and essentially do the labor twice.
