Re: Restoring Rusty - ENGINE TORQUES
let me run some of these ENGINE TORQUES by ya'll and see if you can verify them before I go snappin bolts, the table in the Manual is a bit confusing as it shows specs for the 250, 292, 350, and 454 motards
Oil Pump - 65 lb. ft. (really sounds like a lot) Main Bearing Cap - 70 lb. ft. Oil Pan - 80 lb. in. (1/4-20 bolts) ('member this one is in inches dummy) Oil Pan - 65 lb. in. (5/16-18 bolts) (so which one do I got?) Flywheel - 60 lb. ft. (7/16-20 bolt) Clutch Pressure Plate - 35 lb. ft. Flywheel Housing Cover - 80 lb in. (I hate it when they give you this in inches) |

Re: Restoring Rusty
My book shows the oil pan bolts as:
1/4 - 80 in-lbs (6.7 ft-lbs) 5/16 - 165 in-lbs (13.8 ft-lbs) Don't over torque these, because it distorts the sheet metal and opens up gaps between the bolts, which of course cause leaks. Greg

Oil Pan - 80 lb. in. (1/4-20 bolts) ('member this one is in inches dummy) Oil Pan - 65 lb. in. (5/16-18 bolts) (so which one do I got?) An easy way to size the diameter of bolts is to fit the threads of the bolt into open end wrenches. The 1/4" bolts threaded area will fit nicely in a 1/4" inch wrench, 5/16" bolt threaded area in a 5/16" wrench and so on.
