REMOVAL
WARNING
Cleaning solvent is flammable and its vapor is potentially explosive. Do not use clean-
ing solvent in the vicinity of spark, open flame, or excessive heat. Do not use cleaning
solvent in unventilated spaces. Failure to comply can result in serious injury or death .
Do not allow used hydraulic fluid or cleaning solvent to come in contact with unpro-
tected skin or eyes. Prolonged skin contact can cause illness or injury. Eye contact can
cause serious injury. Always wear chemical protective gloves and goggles when han-
dling used hydraulic fluid and cleaning solvent. Failure to comply can result in illness,
serious injury, or death.
Hydraulic hoses and lines may be under pressure. Relieve pressure by operating the
appropriate control valve if possible. Loosen fittings on hose lines slowly. Allow oil to
run around threads of fitting, releasing pressure before disconnecting fitting. Releasing
pressurized oil suddenly may cause severe personal injury or death.
1.
Don chemical protective gloves and goggles. Use cleaning solvent and wiping rags to clean the work area to prevent
hydraulic system contamination.
2.
Place a suitable drain pan under the starter.
3.
Loosen, but do not remove, the lines (1) from the starting motor (2) to permit any residual hydraulic pressure or fluid to
drain from the system.
4.
Label and disconnect the lines (1) from the starting motor (2). Cap the lines to prevent hydraulic system contamination.
5.
Remove the retaining bolts (3) and lockwashers (4) and lift the starting motor (2) away from the flywheel housing.
