The Quaife differential used on the Stohr is custom made for chain drive race cars.  Early Taylor units are pre-assembled with 3oz of RedLine gear lube.   The diff has a pre-load which can be checked approximately by holding the sprocket and turning one wheel.  The wheel should break away at 85 ft lb of torque.  The large ring nuts on each end of the diff should be checked for tightness occasionally.  A special set of wrenches is needed, call us.

Later Quaife USA units are packed with Mobil grease.  Drive flange studs and nuts must be checked and torqued (24 ft/lbs) every race weekend.  Occasionally check the nuts and bolts shown below.  Check the 6 metal nuts holding the aluminum sprocket flange to the diff.
