Assembly
Assembly is a reversal of the Dismantling procedure.
Note:
1. Exchange or repair all parts that are found to be
damaged. In the case of a damaged planet gear, do not
replace the single gear but the whole reduction stage.
2. Ensure that all the parts are cleaned in the appropriate
solvent and dried with compressed air.
3. Apply a thin film of hydraulic fluid to all sliding parts,
bearings and other contact surfaces before assembly.
4. Replace all O-rings and seals and thoroughly clean the
grooves that they sit in. Cover the O-rings and seals with
petroleum jelly.
Half Seal Installation
The half seals used in re-assembly require a specific
technique to install. Follow the instructions detailed below.
A. Carefully clean the seats 1 and 2 using a small wire brush
or solvent. The surfaces in contact with the O-ring 3
must be perfectly clean and dry.
B. Make sure that the sealing surfaces 4 of the metal rings
are free from scratches and abrasions and foreign
substances and are clean and dry.
C. Carefully clean the contact surface of the metal rings 5
and remove dust and fingerprints. Lubricate them with a
thin film of oil. Take care not to oil the other components.
