Crankshaft Seal Replacement
Separate the crankcase from the cyclinder to replace
the seals. Slide the seals off the crankshaft and clean
the case mating surfaces as previously indicated. Clean
the block where the seal goes and the outside of the
seal with alcohol to ensure they are oil free. If oil is in
the bore or on the seal O.D. the lubrication may cause
the seal to move when hot.
The crankshaft seals on both the R tek and DuraForce
engines are located right on top of a groove in the bore
(Figure 85). The rubber on the outer diameter of the
seal grips the groove and provides a seal as well as
holding the seal in place. Only the PTO seal on the
DuraForce engine has a snap ring installed after the
seal to help hold it in place (Figure 84). As both the
R tek seals and the DuraForce flywheel seal must set
on top of the groove, we do not recommend driving a
new seal in place. Driving the seal over the groove
would damage the rubber on the outside of the seal.
Use some type of seal protector to prevent damage to
the seal lip and slide the seal down the crankshaft. The
seal must rest directly on top of the groove in the block.
Seal the crankcase halves as previously indicated.
Ensure the seal does not move while assembling the
crankcase.
The snap ring on the DuraForce PTO end should be
installed after the six cap screws are torqued down.
Both R tek seals and DuraForce flywheel end seal
The snap ring on the DureaForce PRO end should be
installed after the six cap screws are torqued down.
Both R tek seals and the DuraForce flywheel end seal
location can be checked after assembly. These seals
should be recessed between .040" and .060" (1.016 -
A
1.524mm).
Check the depth in about 3 places to ensure
the seal is at the proper depth and square in the bore.
