for cracks, nicks, burrs, and excessive wear. Inspect
surfaces for scoring, galling, and scratches. Replace

Assembly Notes
NOTICE
• Assemble the reel motor by reversing the order of
disassembly.
• Use a new seal kit during assembly.
• Apply a coat of clean hydraulic oil to all parts to ease
assembly.
• Remove alignment mark from gear set after gears
have been installed with teeth in proper mesh.
• Rotate drive shaft by hand after assembling to make
sure there is no binding between parts; do not force.
• Use extreme care when installing shaft seal. Seal
must seat squarely in seal bore.
• Install retaining screws (10) finger tight and rotate
drive shaft to make sure it turns freely. Tighten
retaining screws (10) evenly in steps to a final torque
of 18.5 lb-ft (25 N·m) and check rotation of drive
shaft.
• Tighten case drain fitting (1) to 15.5 lb-ft (21 N·m).
• Tighten IN/OUT port fittings (2, 3, and 4) to 54.6 lb-ft
(74 N·m).
• Lubricate reel motor through ports with clean
hydraulic oil prior to installing.
It is important that all component parts are
absolutely clean, as contamination can result in
serious damage and/or improper operation.
Never use shop towels or rags to dry parts after
cleaning, as lint may clog passages. Dry parts
using compressed air.
