Hello all, Finaly might have found a 280GE to buy over here in the United States, hired a mechanic to look at the Vehicle and his only concerns were the clutch is getting worn and the syncro into 4th gear is a bit tough unless moved in a bit slow. Thoughts on where to source the parts I will need when I do this work? Thank you.

Re: 280GE Clutch Trans Parts

A manual 280GE. That 's rare. I'm sure someone will confirm, but the clutch should be the same as used on the W123 sedans, so you'll probably find alternative suppliers to the MB dealers. Not sure, but the 4-speed and 5-speed manual may have different clutches (?)

Sachs would be OEM.

 

there are also uprated types:

Re: 280GE Clutch Trans Parts
Thanks Arnie, It is a 4 speed manual and looks original, I am nervous because a couple of sites that sell parts here in the US list it as no longer being available, have been trying to determine if other clutches are indeed compatible but not having much luck.

Re: 280GE Clutch Trans Parts

Yes, but in the US a manual is rare in any car. In europe it's the other way round and certainly from MB the clutch will be available and I have seen other ones on ebay advertised for 4 speed manual.

eg:

However, I'm sure Adrian can sort something for you.

Re: 280GE Clutch Trans Parts
Well it sounds like no one in the states will touch the gear box. A Clutch would be $1500 US approximately installed, which would not take care of the syncro into the fourth and final gear. My mechanic also said the engine came back with compression readings of 115-130psi so he thinks a new engine in 25-50k miles. To rebuild this engine he estimates $18,000 US. Which seams absurd, so does everyone just put a different used/new engine in when it comes time to rebuild?

Re: 280GE Clutch Trans Parts

Well there are outfits here in the UK, that will fit a replacement engine for around USD $1,000. However, the key word here is 'replacement' meaning an engine they've taken from a breaker's yard and then badly fitted to your car.

Of any manufacturer, Mercedes has the greatest availability of parts for older vehicles. If your engine needs a rebuild, I think that could be done with a top-end, cylinder-head rebuild for around $1,500 or maybe $3,500 with a re-bore and new pistons, etc.

Incidentally, these are low-compression engines of 9:1, so I would not expect any higher that 9 x 14.7 psi (at sea-level) = 132 psi on a compression test at cranking speed with throttle wide open for full cylinder fill. Your readings are not far off and perhaps just a cylinder-head, valve service would sort any imbalance. There are other tests that can be done to determine whether piston-rings may be an issue.:https://en.wikipedia.org/wiki/Leak-down_tester

$1,500 for a clutch is also a little on the high side. The gearbox probably just requires a new shift-fork or synchro for 4th gear.
