I have an early 84 shovel, flh. I am doing almost all of the work myself on a total engine rebuild. Hoever, I did take the bottom end to a reputable aftermarket bike shop. They dynamically balanced the flywheel assembly and then sent the pinion flywheel to balancemaster for the mercury treatment. The shop assembled and trued the flywheels. Buttoned up the cases, and handed it back to me. I was instructed to lubricate the pinion ( an aftermarket rodset assembly that I supplied) through the pinion shaft with a trigger type oil can. I used my snap-on siphon gun instead. After I saw oil drooling out of the rods from the pinion, I was satisfied... until I grabbed the rods and rotated the wheels. The most terrible grinding sound came out and I was horrified. At first I thought the bike shop didnt clean out all the glass bead. The crank rolled approx. three times before I could stop it. I inverted the engine stand and clamped the block upside down under my steel table. After rigging up a short piece of 3/8" hose to my siphon gun, I ran about two quarts of brakleen through the pinion shaft while carefully moving the rods back and forth in 1/16" increments, then slowly rotated the crank back and forth while running two quarts of clean mineral spirits through it. I was able to clean it enough so that the sound totally disappeared and lubricated it again. I beleive that a mud dauber wasp plugged my siphon gun(which has happened before) and I shot the plug of sand right into the pinion! After mounting the pistons, rings and jugs, I screwed on the compensator nut and rotated the assembly with a breaker bar. Heres my question! WhenI bring the pistons to the top, I hear a tick-tick and at the bottom it goes tock-tock. This is happening as the crank pin passes TDC. Is ther supposed to be ANY noise while rotating the crank? My KB piston to wall clearance is only .001" When I put my finger tips on the domes, I can feel it as I hear it. With a stethescope on the domes, the noise is really pronounced. Would only three revolutions of the crank wth sand in it destroy the pinion and bearing? Please help!!
