REMOVAL & INSTALLATION
CLUTCH HUB REMOVAL
1. Remove clutch retaining ring or
nut. Use Tri-Tip tool to prevent the
hub plate from turning.
2. Attach the tool to the end plate
by threading the outer nut of the
tool into the center hole of the
clutch end plate.
3. Tighten the inner tool arbor
against the end of the compressor
shaft to lift the plate.
Tech Tip: Proper air gap between
the clutch pulley and hub armature
is critical to compressor overall
performance. Failure to maintain
the proper spacing, as indicated in
the manufacturers specifications
can lead to problems such as clutch
burning or slippage.
