I had recently acquired a John Deere Sabre that had a blown 20 HP Briggs and Stratton Vanguard engine. Good engine if it didn't throw the connecting rod out the side of the block.
Anyway, I wanted to attempt rebuilding it from other existing parts I had from other Vanguard engines. I replaced the block, connecting rod, and camshaft. Everything was bolting together nicely until I went to tighten down the oil sump on the engine. When I tightened the bolts, the crankshaft would not spin at all. When the oil sump bolts were loosened a bit, it would spin freely like it normally should. It was as if the crankshaft was rubbing against something in the engine.
One thing I will note is that I did have to replace the oil seal and bearings on the flywheel side. I thought I had it pressed in far enough but I am not quite sure. I used a hydraulic press to achieve this.
All of the other parts are in good condition, but I am puzzled on what I can do to make it so the crank will spin normally. Can anyone help me? I can post pictures if you need them.
