1. Lightly lube and insert the handle end Spool Seal first.
Verify seal fit by carefully running your finger around
the exposed edge of the seal. You should have a
smooth, perfect ridge with no kinks or twists.
2. Lightly oil the valve spool. Using a slight twisting motion,
carefully re-introduce the spool into the valve housing,
starting from the positioner end. Do NOT force the spool
into housing. Once started, the spool should float freely
through the housing until it comes in contact with the spool
seal. Carefully push the spool through the spool seal with a
twisting motion.
3. While watching from the positioner end, pull the spool
into the housing from the handle end. Stop when the seal
groove is exposed.
If the spool is pulled in too far, the spool notches may be
moved into the seal area on the handle end of the housing.
If this happens Do NOT force the spool back out the
positioner end of the housing. Carefully remove the spool
by pulling it out the handle end of the housing. Once the
spool is removed, inspect the front spool seal and replace if
damaged.
4. Lightly lube and install the remaining spool seal. Once
again using a twisting motion, push the spool through the
spool seal.
5. Return the valve spool to the center position and re-
attach the handle and positioner hardware.
