VALVE-BREAKER RELIEF 9T0818 - Caterpillar

Remove Magneto
1. Disconnect connector (2) at magneto (1).2. Give support to magneto (1) and remove the bolts that hold magneto (1) to magneto drive (3).3. Remove magneto (1).Install Magneto
1. Put a new gasket on the magneto flange and install the bolts that hold the magneto to the magneto drive.2. Connect connector (2) to magneto (1).3. Refer to the topic MAGNETO TIMING for correct magneto timing procedure. Disassemble Magneto
start by:a) remove magneto1. Remove four screws that hold cover (1) to intermediate housing (2) and unplug connector (3).
Put a mark for alignment on the connector halves. Hold both halves of the connector. Do not pull the wires to separate the connector.
2. Remove timing cover (4), screw (5) and timing label (6).3. Remove screws (7) and nut (8) for the diode.4. Remove driven gear (9).5. Tilt circuit board (10) away from pick-up coils and unplug the wires from the pick-up coils at the circuit board pin connectors. Do not lose plastic brace when circuit board is moved away from pick-up coils.
Use needle nose pliers to unplug the receptacles at the pin connectors. Do not pull the wires to disconnect the pin connectors.
6. Use tool (A) to give support to end cover (1) in a press.7. Use tool (B), or rod of same dimension, in a press to move distributor shaft, bearing and timer arm assembly (11) out of end cover (1).8. Use tool (A) to hold timer arm assembly (11) so shaft bearing can be pressed out of aluminum hub in timer arm assembly (11). 9. Remove spring pin (12) and drive coupling (13).
Put identification on flange (14) and housing (15) so flange (14) can be installed in the same position.
10. Remove flange (14) from front housing (15).11. Give support to flange (14) with tool (A) in a press and use tool (C) to remove seal (16) from the flange.12. Disconnect stator wires from clamp (18).13. Remove three screws that hold intermediate housing (17) to stator and front housing (15) and remove intermediate housing (17). use a soft hammer to separate intermediate housing (17) from the stator.
Intermediate housing (17) fits on a bearing rubber cover on the rotor assembly.
Put a mark for alignment on stator (21) and front housing (15).
14. Remove drive gear (19), bearing rubber cover (20) and stator (21).15. Put front housing (15) in tool (A) in a press shaft and rotor assembly out of front housing (15).
Do not let the shaft and rotor assembly fall after it is clear of the bearing.
16. Put front housing (15) on tool (A) in a press and use tool (C) to remove the bearing from the front housing.17. Use tool (A) to hold bearing (22) in a press. Press shaft and rotor assembly (23) out of bearing (22).
Do not let the shaft and rotor assembly fall after it is clear of the bearing.
18. Replace all parts contained in the repair kit.19. Clean all parts and remove metal filings from the magnet-rotor.Assemble Magneto
1. Put spacer (2) in position on the drive gear
