Question Starting a 1985 300 D after it has sat 3 years

Hello,
I have a 1985 300 D that has sat 3 years without being started.
I attempted to start it after fully charging the battery and just heard the click of the starter solenoid. I know that the Battery is sound and is holding a full charge, and I believe the starter is good., but I think things may have gotten a bit "stuck" and there is too much of a load to turn that mighty 5 cylinder diesel . Is there a good way I can manually turn this over ? If so which way(as you face it) does the engine turn.
This would be fairly straight forward for me if this were a gas engine, but I am not that well versed with diesel, any suggestions would be appreciaterd
Thank you,

Paul

Try turning the engine over by hand, 22mm wrench on the power steering belt usually works. If you attempted to charge the battery that has sat in that car for 3 years, chances are that it has a dead cell....go buy a brand new battery...

Corrosion on the battery terminals? You might not see it on the outside, could be worth a look. Do try a jump start - your current battery could be weak.

Having said all that do you know that it was running for sure when it got parked 3 years ago?

Proceed to the W123 forum, they're almost all dieselheads there.

I've had new batteries turn to junk after sitting for only 1 - 2 years. You charge & charge & charge them and they still won't handle the starting load. Do your dash warning lights blink out when you try the starter? If the cable connections are OK, just save time & aggravation and get a new battery. Or, if you're reluctant to invest in a new battery yet, at least try it with one out of a currently running vehicle.

Happy Motoring, Mark
