well my questions are how to retime and motor. crank,cam,and pump?
Set the pistons to TDC. You should be able to see the mark on the flywheel through the timing hole. Good time to measure for the proper gasket thickness (one, two, or three hole).
Put the head back on, set the pump to where the pin can fit. It might be off, but it won't kill the engine if it's 180 out. It shouldn't have moved anyway, if it was already pinned and the belt was loose.
The last think you install is the cam sprocket. Slip the new belt on over the sprockets, including the loose cam one. Put the camshaft so the lobes are all pointing up, and the slot at the end of the cam fits the retaining plate flat.
Install the belt, make sure you're still on time, tighten the cam sprocket down, adjust the belt tensioner, rotate the engine BY HAND twice around to make sure you haven't buggered anything up.
This is why you unhook the battery first thing, btw, matchmark and take a picture of everything first.
