Jack, what did you decide on the fix for the tensioner bolt threads?
I got a Helicoil kit from NAPA that worked great. I've been putting the engine back together and I ran into another problem. I went to set time and tension the belt, after doing so I removed all Lock Pins and went to rotate the engine by hand and the crankshaft gets bound up and stops turning. I am fairly certain my timing was correct on everything because the pins fit fine and with the crankshaft pin fully inserted it only had a mild amount of play which I used to get the belt tight between the crankshaft and the injection pump. I'm not very sure how to proceed
Where was the mark on the crankshaft when you had the pins inserted? Was it at 3:00?
There are more than one hole in the flexplate (flywheel) where the alignment pin will screw in.
If it is binding up and will not make a complete rotation, it may be out of time and one of the pistons is making contact with a valve(s)?
DO NOT try and force it beyond this point or you may break something!
If you can rotate backwards to where the crankshaft mark/dimple is at 3:00, the cam pins should be lined up and allow them to be inserted.
IF NOT, set the crank at 3:00, insert flywheel pin, then remove timing tension and rotate cams until you can insert cam pins.
You may have to re-loosen the cam gear bolts using the proper holding holding tool to retension the belt properly after you get everything properly aligned again.
Very important! Having the crankshaft dimple mark at 3:00 will allow you to rotate the cams to any position as the pistons will ALL be setting at half travel which will not allow any valves to contact the tops of the pistons.
Post what you find!
Mark should be here:
