Ok.
I've been thinking about this for a while, but i can't excatly work out what the best way is.
I've got this diesel engine from the loon, and it needs a new crank. I've been thinking of the best way to take it out and replace it without pulling down the top end.
The procedure thus far, that i have nutted out.
In parentheses i have put the possibly problems with this method.
With engine removed.
1 Remove flywheel
2 Remove Driven plate 6 bolts. Mark Flywheel position. (Problem: If i use a different crank in reinstallation, the new crank will not be marked)
3 Lock Camshaft and injector pump
4 Remove front sprocket, timing belt, seal plates, etc.
5 Remove sump, oil pump.
6 Mark Conrods and big end bearing caps 1, 2, 3, 4 (With crankshaft remaining in one position, it will be hard to access each conrod- can i turn the pistons over with the valves locked in position?
7 Remove big end bearing caps.
8 Push pistons slightly up cylinder. Fit pieces of plastic tube to bolts.
9 Remove main bearing caps, remove crankshaft.
The problems i have are with marking the conrod caps, and possibly having to turn the engine over to remove each conrod.
Should i be worried, or am i being a moron?
Also, when i am retiming the crankshaft to TDC, a dial gauge would normally be used on the top of the piston right?
If i've still got the head on, how can i do this? It will be too inaccturate to do it on the crank somewhere..
