    We are putting all the components back on our mx 13 before we stab it back in but are having a hell of a time finding torque specs. I know i can spend six hundred on a service manual but isn't there a website or something? Mainly looking for bell housing, motor mounts, oil pan, clutch, flywheel, etc

    When all else fails, you can never go wrong with universal bolt torque by thread size, pitch size and bolt hardness. Only time you really need to defer from this would be everything inside the engine, cylinder head, top end and bottom end are torque turn specs or tty.

    Cat service info is the most frustrating for me to find torque specs. If I looked up every bolt spec I would die before I got a rebuild done.

    Here are most of torques you asked on engine. Paccar changes clutch and engine to trans fastener torque all the time! Clutch I usually go with new lock washers and 45 ft/lb on M10 bolts. Engine to trans I use blue threadlocker and 50 ft/lb on M10 bolts. KW has service manual for the new style trelleborg motor mounts so I attached that also.
    P.S. Yes, flywheel bolts spec is correct and is very tight. I replace the bolts with new.
