Ready to replace the oil pan(300 SDL),

Should I change at the same time,the Oil Pump Chain Guide/Rail?


Thanks for your kind help,

I haven`t hear of these coming apart all that often...but I think it was AH-Kay that
had one come apart. I may have been on his SDL also.

I have never changed one, so don`t know the process you have to go through.

IIRC the front cover has to come off to replace the oil pump chain. Are you up for that? Is the engine out of the car?

Engine is not out of the car,

It is the first time i am changing the oil pan,

I thought.... changing the plastic chain/guide,at the same time,

sound like over doing,

thanks for the replies,

Removing the front cover without pulling the head and without damaging the head gasket isn't easy but it's worth pursuing with the engine out of the car which it pretty much has to be to replace the oil pan. Or do you mean just the side compartment?

excellent view,

much appreciate

engine will be lifted 3-4"

Just changing oil pan,

did not realize how deep the oil pump chain.

Thanks for you kind help,

I had an oil pump chain snapped in a 300SDL while cruising at 70+mph. Rod bearings and pistons starved of oil and engine seized. It is a single chain rather than a double chain like the OM617. I rehab'ed the engine, changed the chain but not the guide rail. The guide rail was plastic and is very durable.

The engine front plate needs to come off to replace guide rail and loop chain. I am not sure whether you can buy loop chain. I crimped the chain in place as it comes with a master link. I now replace the chain if I had a need to replace the pan. I err on the side of caution.

Another caution note: Fill the oil pump with vaseline before installing. The oil uptake may not work well on the OM60X engine when oil is drained completely from the pump.
