Glad to see there is some else with a gas engine. Too many diesels out there.
Here are the torque values, all in foot pounds of torque:
Clutch cover plate to flywheel 25-30
Fuel pump assembly to cylinder block 40-50
Flywheel housing to cylinder block 70-75
Connecting rod cap bolt nuts 65-70
Crankshaft main bearing cap bolts 90-95
Flywheel to crankshaft 60-67
Cylinder head bolts 100-105
Oil pump assembly to cylinder block 25-30
Timing gear to camshaft 20-25
Camshaft thrust plate to cylinder block 15-20
Clutch balancing weight screws 20
Clutch release lever thrust plate to pressure plate cover 15
Spark plug to cylinder head 20-30
Pulley to vibration damper retaining screws 15-20
Generator mounting crews 15-20
This came out of TM9-2805-222-35, Field and Depot Maintenance Manual for Engine (REO model OA-331), Clutch (Long Model 12-CF). You should try and get a copy of this. You will also want to get TM9-2805-222-35P, the parts list for the Reo OA-331 engine. Lots of excellent exploded views of assemblies. I'm working on a gas M35 and M34 at the present myself. Good luck in your efforts.
