a. When installing fittings in the oil coolers, care should be used to prevent excessive
torque being applied to the cooler. Where a rectangular fitting boss is provided, a back-up
wrench should be used, employing a scissor motion, so that no load is transmitted to the
cooler. When the oil cooler has a round fitting boss, care should be taken not to permit
excessive torque on the fittings.
b. If a pipe thread fitting is used. it should be installed only far enough to seal with
sealing compound.
c. Apply Lubon No. 404 to all male pipe thread fittings: do not allow sealant to enter
the system.
d. If fitting cannot be positioned correctly using a torque of 10 to 15 foot-pounds,
another fitting should be used.
e. When attaching lines to the cooler, a back-up wrench should be used.
