Looks to be the correct set. If it does include the dust cap, grease seal and washer then that's a pretty fair price.

Drained the fluid from my injection pump today. Strangely, it didn't appear like it was oil. It had the consistency and colour of Diesel but without any of the smell. It could have been an additive but there appeared to be nothing with oil like texture or consistency in the pump. We drained the fluid entirely and replaced it with the Liqui Moly MOS2 10W-40 oil for now.

Any thoughts on what happened?

They could have used mineral oil or its ilk. No biggie as the oil in the pump does not circulate through the system. Thinning occurs as a natural state of affairs as there is always a slight seepage of diesel into the pump.

I'd be cautious using an additive in the pump oil. The leather used in the governor diaphragm can be sensitive to some chemicals. Adding the Moly might not be the best thing for the internals of the pump. Probably won't hurt it but I doubt if it helps it either.

Just drove the car home. IP flush with new oil, new mounts and engine strut, valve adjustment and new brakes among other things have really improved smoothness.

We did find the central locking "bellows" or actuators are leaking. Is there a kit or a replacement part # that folks use to replace these?

The actuators are still available, I believe. Don't bother with "rebuild" kits that contain the diaphragm, as they're a ripoff and you'll most likely destroy the actuator trying to disassemble it, since it's 50 year old plastic.

Part number is 115 800 22 75. No longer available. :crying

You might find an NOS one out there if you look. I looked at my reproduction sources in Germany and they're not making them. Might want to check the Mercedes Club of Germany, no telling what they might have.

Sorry.

Remember when the dealer that sent me the rear wheel bearings instead of the front? Well, they were kind enough to take the charge off and let me keep them. Turns out the same kit will work for both W115/ W123 chassis models, both of which I own, so probably sensible to hold on to them.

Given the front wheel bearing grease appeared and felt more like solid rubber instead of grease, I suspect the rear bearing grease is in similar, long expired condition. Is there any sense in attempting to replenish grease in the rear hubs? Can it be done without disassembling the entire hub, which I believe will require a press tool?

Next wave of parts have been ordered:

1) Transmission mount - A1232402518
2) Differential mount - A1233511142
3) Front sway bar kit - A1153200047
4) Rear sub frame mounts - A1163500075
5) Speedometer Cable - A1145420207
6) Fuel Sending unit - A1105421204/64
7) Hazard light pull switch with relay assembly - A0015449532

All of the above were available from the main dealer - simply amazing!

Also ordered a set of 175/ 80 R14 Continental EcoContact 6 tyres, which are considered best in class for the OE size. These will sit on the 14 inch "steelies", and should really improve the character of the ride.

Finally, was able to source a pair of original W115 ribbed rubber rear floor mats new from Argentina. They'll look great over the new OE look carpets I've installed from Coverdale.

After the original radiator developed a serious leak, I've gone ahead with the following dealer parts
order to get the front end cooling system to like new condition, in addition to several other parts that needed replacing (listed with part numbers and descriptions for fellow forum member convenience):

1) A1081800265 - Oil Cooler (eBay purchase - OE supplier AVA cooler)
2) A1087200016 - Drivers door check strap
3) A1154900115 - OE mid-section exhaust (NLA - eBay.de purchase - OE supplier IMASAF)
4) A1154900715 - Rear end exhaust (will connect to the IMASAF middle exhaust)
5) A1234920714 - Chrome exhaust tailpipe tip/ cover (love the look of these!)
6) A1235000012 - Radiator mount kit
7) A1145000112 - Radiator side mount kit (NLA - supplied NOS by Joseph Beerbower via eBay)
8) A6151870082 - Upper oil cooler hose (NLA - eBay.de NOS purchase )
9) A1155011782 - Upper Radiator Hose
10) A1155011882 - Lower Radiator Hose
11) A6152030282 - Coolant Bypass Hose (smallest hose, difficult to install)
12) A1158311094 - Water pump to heating system Hose
13) A1102001720/80 - Replacement water pump with both replacement gaskets
14) A1156840205 - Ribbed rubber Trunk liner (eBay seller W114selo)
15) A1154200072 - Rear corrosion coated brake discs (ATE)
16) 24-005265 - Bilstein Heavy Duty front shock absorbers with mounting hardware

Annoyingly, I cannot locate a new lower oil cooler hose (#A6151800082 - also NLA - any leads are more than welcome). I'm also considering sending the injectors and lift pump to the diesel injector guru for servicing. Thoughts/ opinions on these and anything I may have forgotten to focus on is also more than welcome!

Once the above mechanical work is complete, most of the remaining work is suspension or cosmetically related, targeted for 2020.

Time flies! It's been a couple months of trial and error trying to find the correct exhaust components for the car. After ordering multiple incorrect parts, finally went with a stainless steel fabricated downpipe and mid pipe, both of which connect to the dealer supplied rear exhaust manifold.

Drove the car 40 miles today and the improvement in power delivery and engine refinement is very apparent following the installation of the rebuilt injectors and lift pump. Greazzer's work speaks for itself.

The car hasn't stalled (yet) and it now starts without any throttle, a first!

Thought I'd circle back to this thread to share that the car is back, leak free and running at a constant steady temperature regardless of traffic or speed. Fan belt squeal is also gone, probably due to the new MB water pump.

We really went to town on preventative maintenance. The final list includes:

1) New MB short hose
2) New MB Water pump
3) New MB Thermostat
4) New MB Fan Belts
5) New Monark pencil glow plugs
6) New Monark injector nozzles (Rebuilt by Diesel Injector Guru Greazzer)
7) New OFV (from Diesel Injector Guru Greazzer)
8) New MB Oil Cooler Hoses (New Old Stock)
9) New fuel filters and hoses
10) Citric Acid flush, then rebuilt radiator and steam cleaned and painted oil cooler
11) Sanded down all pitting/ corrosion from aluminum housings

Interestingly and unexpectedly, the car's heating system has REALLY improved. Heats up very noticeably in <5 mins and get's really toasty in < 10 mins. And that's without the fan on!

Blue coolant is back in the system she's sealed up for another decade (hopefully!)
