1 Supplied drive gears should be inspected for the following
Report any damage to gears through NCR system to log and retrieve replacement gears
Any rust/ surface contaminate should be removed with a wire brush
Drive shafts should be inspected for the following
1 Damage to indicated thread
2 Presence of burrs on roll pin hole
3 Contaminates from hardening
Damage to thread should be reported by NCR system and replacement sourced
Burrs should be removed by file
Contaminates should be removed with Scotch brite pad
It is vital for correct function that all the shown components are thoroughly degreased before assembly .
To do this, wash all parts with FE10 solvent spray and dry with airline.
1 Check plate D0008158 for any number etching. If it is present it should always be assembled with the etching to be on the face shown
2 Mount plate over drive dog, and then press bearing onto shaft to encapsulate the plate. When the bearing is fitted the plate should still be free to move in the gap left
1 Fit bevel gear onto assembly orientated as shown
2 Fit Bearing to top of shaft as indicated remembering to check fit of bearing
Castle nut will need fair tension to correctly hold the assembly together
It is best to hold the assembly in a vice to enable the nut to be tensioned correctly.
Use 2 m5 x 70 cap head screws and 2 m5 nuts
Screw the bolts into the two holes shown and lock off the two m5 nuts to strengthen the the two temporary mounting points
Clamp the two m5 bolt shanks in the vice to avoid damage to the assemblyUse loctite 243 on castle nut and use correct castle nut spanner to tension.
Ensure castle nut is fitted in the orientation shown. Larger flat face should facing outwards, smaller face should contact bearing
1 Add 3 match head sized drops of bearing fit to indicated bore and smear around
2 Add 3 match head sized drops of bearing fit to indicated bore and smear around
3 Insert by hand 1st bevel gear assembly into bore, there should be slight resistance but no more pressure than hand pressure should be required. 4 Ensure assembly is pushed fully in then captivate with 6 off m3x10 cap head bolts with no washers with loctite 243. Once tight pen mark bolts to shown completed
Once all fitted rotation of assembly in housing should be checked . Rotation should be smooth and consistent with no high spots or lumps
