Hey guys, I'm trying my hand (first time) at rebuilding a 1600 DP motor. I got everything together (I've been following the Bug Me Videos) except for the flywheel and clutch. I noticed that when I push and pull the pulley the crank will move back and forth. The main bearing at the front of the engine does not move when the crank does. When I placed the bearings, everything felt snug.
Then when I turn the motor by hand there is a point in the rotation where the pulley wheel will push out and then pull back in towards the motor. Trying to figure out what's wrong. Again, I have not installed the flywheel yet. Any ideas on what my next step should be or if this is normal?

Can't set endplay without flywheel being installed first right? Again total neb here!

Correct, the endplay is set by installing a set of three shims between the #1 bearing and the flywheel with it bolted/torqued properly to the crank.

Correct , two shims , torque flywheel (100# or more), measure endplay. Subract.004 ", result should be third shim thickness , remove flywheel, add third shim, torque flywheel again, recheck endplay . If in spec . (.003-.005). Good to go. Remove flywheel , install crank seal, install o ring , using appropriate libricants ( Bentley has this) , reinstall flywheel , torque to spec, 270 ft/lbs . Done. Good luck, dont forget to report back

Thanks, guys! So, it seems that the movement of the crankshaft doesn't seem to be a concern at this point. Best thing to do is finish out the build by installing flywheel, setting endplay and going from there.

Just make sure that if you have the distributor drive gear installed and it's 2 washers that you have the distributor on and clamped in so the brass gear does not get in a bind against the distributor drive gear if it pushes it up.

It's been a year, but I literally just got this engine finally pulled altogether. Once I installed the flywheel I was able to set the endplay to exact specs and everything was tight as could be; no movement. Bench started it and ran it to seal the piston rings. Things ran great. Thanks for the tips. Thought I'd give an update.
