Looks like both engine mounts are next in my series of catching up on the list of deferred maintenance items on my SDL. I plan on changing the transmission mount at the same time and the engine shocks and grommets on both sides.

I've done the mounts already on my 300D - I'm hoping the steps are similar, though I've never replaced the transmission mount before - not sure what the steps are. I've tried to lookup the FSM procedure on the mounts, but the manual only talked about a function of the motor mounts not how to remove them.

I plan on following DieselGiant's steps as part of the oil cooler line replacement process for 617 - I have some questions specific to the SDL:

1) Is it ok to jack up the engine by placing a sturdy block of wood under the oil pan?! The pan is aluminum and the engine is a beast, so I wanted just to make sure.

2) The FSM mentions the engine stop adjustment?! Does my engine have an engine stop that I need to worry about before I start to jack it up? Not even sure what that looks like...

3) How far up should I lift the engine? On my 300D I wasn't sure either and was advised here to take off the fan shroud and jack up until the back of the valve cover hit the firewall - it was a good advice. It worked well.

4) Are there any steps describing the R&R of the transmission mount on the SDL?!

Yes you can.
Before jacking up any diesel engine the long axial shaft connecting to the firewall should be disconnected.
Only as far as you need to. I never took the shroud off and never even came close to hitting the firewall.

Thanks Danny - I'm wondering what that long axial shaft might be - you mention the firewall - is this piece on top of the engine, mid- or underneath?!

You don't have a long axial shaft on the 603. He's talking about a different engine and didn't read the OP.

Guess I'll just go for it and hope for the best - thx
