Engine Torque Specification in foot pounds. Cylinder Head nuts-*---10mm studs--------------24'# Cylinder Head nuts-*----8mm studs--------------18'# Flywheel Nut------------------------------------217'# Crank Pulley nut-------------------------------29/36'# Connecting Rod nuts------------------------------24'# Crankcase 12mm---------------------------------24'# Crankcase 8mm----------------------------------15'# Rocker Arm nuts------------------------------14/18'# Clutch Pressure Plate-----------------------------18'# Spark Plug------------------------------------20/29'# Generator Pulley------------------------------40/47'# Blower Fan nut-------------------------------40/47'# Oil Pump to Case 8mm nuts----------------------14'# Oil Strainer Plate 6mm-----------------------------5'# Oil Drain plug 14mm------------------------------25'# Remember that one foot out and one pound pressure is equal to 1'# (one foot lbs) So, 250 foot lbs is the same as 62.5 pounds of pressure 4 feet out from the center of the nut.. ( 250 divided by 4 = 62.5 ) Up or Down ? Any markings on the VW always go UP or FORWARD towards flywheel (front) Several places you will see markings on the VW part will be an arrow on top of the piston. It must point towards the flywheel end of the motor, another is the raised boss cast into the rod beam it will be up on the top side when the rod is installed. Flywheel Gland Nut Torque is critical (to much or to little and the flywheel will come loose). Be sure to follow the torque figures supplied with you new Gland Nut. The stock Gland nut torques to 217 ft lbs HD Chromoly gland nuts torque to 250'# and can be reused. *ck The HD Chromoly gland nut will stand higher torque but the stock crank is the limiting factor and maximum torque should be 250/270'# . Crank info.->*Click Head Torque* and Tightening Sequence on the Head Nuts is very important.->*Click When disassembling a motor with 10mm head studs and no case savers you can check the head studs in the following manner. Loosen each head nut and then torque it to 45/50'#, if it holds then it is ok, if not it needs to be repaired by installing case savers. Then loosen and re-torque to 24'#. Do this to each stud one at a time. If it will not hold the 45/51foot lbs cold it will not hold the 24'# when it's running. It is better to find out now that you need to install case savers then 100 miles later. Go Back Victor Comp.
