om 617a help
Hi, just need a little advice on reassembling my om617a (from an early 80's 300 turbo diesel). I can't find any starting point for locating the injection pump sprocket relative to TDC when installing a new timing chain. I had difficulty getting the chain out and in a dumbass move rotated the sprocket and didn't punch a ref. mark. Also, is it extremely difficult to rebearing and seal the turbo? Apperantly the engine (allthough low miles) was run upside down starving the crank(replaced) and turbo(rebearing due to excessive radial play?). I can't detect any other damage. I am swapping it into my Unimog, and my experience with diesels is weak. Any other thoughts and advice is appreciated.
