Thanks that's the one.
The part number I gave below was for the metal mount re: my shock absorber question

I am not an expert but some of the forum members have said on their vehicles when they looked up the part numbers there was a different part number for the left and right. I have no idea on which vehicles that is the case.

I pulled the old passenger side mount out of the garbage and the number on it was 123-241-12-13. Based on what I've seen for other parts of the car that mount is presumably original but I can't guarantee that. The driver side mount was an off brand replacement so no part number. You were right on the original part number you had. My dealer has a part with that part number and it's a whopping $135 per mount. I'm on a budget so I went with the closest thing I could find for a reasonable price.

Your car should not have engine shocks. That was the OM617. But it should have a fourth engine mount on the front of the engine. A T-mount I think it's called. That should be replaced as well.

Understood but I am interested in a retrofit vs. oe replacement. Specifically, what would that involve. I just found a retrofit job in the fsm. I’ll report back if it’s relevant.

FSM answered my question. The piston type shock absorbers are only used on models with automatic transmissions. It wasn’t applicable to manual transmissions.

On 240Ds? I've never heard of them on anything but the 300's.

I’m not entirely certain now that you mention it. I just got an FSM and still trying to figure things out. For example: My 240D w123 chassis code is 123(123.123)
123.133 is 300D
123.190 is 300TD na
123.193 is 309TD turbo and so on
The FSM has engine shock absorber(piston type) service jobs for the following :
“616 in type 115.1”
“615, 616 in type 123.1”

What is ‘…type 115.1/123.1’? Does that just mean diesel? seems redundant to say 615, 616 in both diesel chassis types.

If the .1 equates to diesel engine then I would conclude both the w115 and w123 chassis with engines 615, 616, and 617 used a piston style shock absorber but not on every model year. For w123 the piston style was only used for models with the automatic transmission.

115 is the earlier square looking car. Don't know what the .1 designation refers to. I had never heard of a 240 engine having a engine shocks, only the front T-mount. I thought only the 5 cylinder 300 engines had them. But my info comes only from the two 240D maual transmission cars I owned and online sources. Might not be complete.

The ".1" does seem to refer to the diesel powerplants.
Three diesels were offered in the W115 chassis: OM615 (NA), OM616 (NA) and OM617 (NA).
Four diesels were offered in the W123: OM615, OM616, OM617, and OM617A (Turbo).

So, the service job is excluding the W115 variants with an OM615 or OM617, and also excluding the W123 variants with an OM617 or OM617A.

That’s not how I interpret it at all.

Service Job 00-240
“Removal and Installation of Engine Shock Absorber”

Procedures detailed for:
A. Engine 616 in type 115.1
B. Engine 617 in type 115.1
C. Engines 616, 616 in type 123.1
D. Engine 617 in type 123.1

Service Job 00-241
“Retrofitting engine shock absorber (engines 615, 616 in type 123.1)

Does it provide actual part numbers for these shocks? Because that makes no sense as I understant it. Once again. I've never seen or heard of a 123 four cylinder diesel with the engine shocks. Or the earlier car. Would be helpful if anyone with them could post pic's.

I can’t find anything but Febi, URO, and a bunch of off brand manufacturers for my 240D. I found Swag but as they are under the Febi-Bilstein umbrella and in this case offered by a seller with Febi using the same pictures item, i don’t expect to get anything different. It seems at this point the choice is $200 for genuine mercedes or $20 for pick your flavor of made in china. i haven’t found any that advertise or picture the part as original with two green dots.
I did find some new old stock Lemforder 300S? gas engine models. Has anyone found a euro spec manufacturer for 240D mounts other than Benz. For that matter MB could be outsourcing to China by now.
