Cecil Davis 14 #1 Posted June 23, 2019 I do have a problem. I started reassembly today. Discovered I had put the connecting rod on the Piston head backwards. I checked the clearance plastigage on the journal and it looked good. Then I put it on the journal, got the rings inside the cylinder and added the rod cap back. I torqued to the spec on the sheet included with the connecting rod. 3/8 hex to 160 in. lbs per the instructions with the rod (OE Briggs) and 1/2 hex to 260 inch lbs. Nothing would move. l loosened both bolts and the piston would move. I torqued both to 120 inch lbs. Nothing would move. I torqued both to 100 inch lbs, which is the spec for smaller engines and it moved up and down. The spec on the Briggs chart for 25000 series engines is 185 inch lbs. Any ideas?

A cap installed backwards might plasti gauge showing the proper clearance but the cap itself maybe misaligned against the side of the crank journal. 1 Share this post Link to post Share on other sites
