Con rod and big end bearing caps are line bored at the manufacturing stage. Replacing the caps in the original positions keeps the caps in line to the original machining. By mixing the caps, you could well run the risk of running the bearings inside the caps
The 12mm bolts on each end bearing cap should be torqued to 14 ftlbs. The 10mm bolts on the bearing caps in between should be torqued at 8 ftlbs. This is from the Mitsubishi 6G7 overhaul manual for the DOHC engine. next time post your engine, if is turbo or not... that will help
If it's a 4 bolt Then the outer bolts for #2, 3 and 4 caps are 70 ft lbs all others bolts are 80 ft. lbs If its a 2 bolt main engine the torque spec's are 80 FT. lbs For all caps.
You have rod bearing caps that hold the rods on the crankshaft. And you also have main bearing caps that hold the crankshaft in the engine block. NEUTZ.
Ring gear 90 ft pounds Bearing caps 60 ft pounds
The 1999 Saturn main bearing cap torque specifications are 160 pounds per square inch. The main bearing cap bolts should be torqued in 40 pound intervals.
All main bearing caps should be tightened to 85 foot-pounds.
Crown wheel bolts 58Nm, use `Loctite Studlock` Bearing caps 90Nm.
the torque setting for the the main bearings of the Toyota 2c engine is 103 Nm. The rid bearing caps are 59 Nm
You can purchase new or used bearing caps, but there is machine work required. If you are talking about main bearing caps, the block will need to be line bored with the new cap in place. If you're talking about a connecting rod bearing cap, the rod will need to be resized with the new bearing cap in place.
inner main caps 70 ft. lbs, outer main caps 65 ft. connecting rod torques are 45 ft. lbs (caps)
If you are talking about torquing down the main bearing caps, the two inner bolts are the ones closest to the center of the cap, and the outers are furthest away.
