6. Remove valve block (7).
O–ring Replacement
7. Remove gear housing. Make sure rear bearing block remains on drive and idler gear shafts.
1. Remove dowel pins (6) and O–rings (5) from gear housing. Clean O–ring grooves.
8. Remove rear bearing block from drive and idler gear shafts.
2. Apply a light coating of grease or petroleum jelly to O– ring grooves in gear housing and install new O–rings in each groove.
9. Before removing gear set, apply marking dye to mating teeth to retain “timing”. Motor efficiency may be affected if the teeth are not installed in the same position during reassembly. 10. Remove idler gear. 11. Remove drive gear and shaft slowly until drive end is through shaft seal. 12. Remove front bearing block. 13. Wash all parts in cleaning solvent. Check all parts for burrs, scoring, nicks and other damage. If gears, housing or bearing blocks are damaged or severely worn, entire motor should be replaced. Seal Replacement (Motor Disassembled)
Reassembly 1. Put flange (3) on a flat surface with shaft seal facing down. Make sure back side of flange is free of contamination. 2. Put front bearing block, seal side down, on flange. 3. Apply a light coating of oil to exposed face of bearing block. Put tape or seal protector tool (TOR4072) over splined end of drive shaft. Insert drive shaft through bearing block and shaft seal. 4. Put idler gear on bearing block. Apply a light coating of oil to back face of drive and idler gears. 5. Put rear bearing block, seal side up, on drive and idler gear shafts.
2. Remove shaft seal, being careful not to scratch seal bore in flange. Scratches in seal bore could cause leakage. Make sure seal bore is clean. 3. Put new shaft seal (part number side up) in seal bore and press seal into bore until seal reaches bottom of bore. Uniform pressure must be applied to face of shaft seal to prevent damage to seal and misalignment in seal bore. 4. Install retaining ring with sharp edge facing out.
6. Install the two front dowel pins in the flange. 7. Carefully install gear housing over rear bearing block and slide gear housing down over the gears and front bearing block. Make sure the markings put on the flange and housing earlier line up. 8. The rear bearing block should sit just below back face of gear housing. If bearing block sits higher that rear face of housing, remove gear housing and check that E–seal or O–ring did not shift out of place during assembly. 9. Install remaining two dowel pins in rear of gear housing, then put end cover on back of motor.
E–seal Replacement 1. Put bearing block on a clean, flat surface with E–seal (4) facing up. Remove E–seal. Clean E–seal groove. 2. Apply a light coating of grease or petroleum jelly in E– seal groove and on back (flat) side of new E–seal. Put E–seal, flat side up, into groove in bearing block. 3. Repeat for other bearing block.
Reelmaster 6500–D/6700–D
10. After motor has been assembled, tighten capscrews by hand. Tighten the capscrews evenly in a crossing pattern to a torque of 40 – 45 ft–lb. 11. Put a small amount of hydraulic oil in port on motor and rotate driveshaft one revolution. Protect the shaft if using a pliers. If drive shaft binds, disassemble motor and repeat assembly process.
