Replacing hydrostatic transmission axle sealing collars

Sealing collar replacement - input axle

Remove the cooling fan, it is held by a circlip. Rem- ove the pulley from the input axle by pulling it upwards and then removing the circlip under the pulley.

IMPORTANT INFORMATION

The area around the sealing collar must be absolutely clean! If the hydrostatic oil is contaminated with dirt, this can lead to a shorter hydrostatic transmission operational life.

1

•Clean the input axle and the area around the sealing collar of all dirt and rust.

•Insert a screwdriver between the sealing collar and the axle and bend the sealing collar out of the axle housing with a twisting motion.

2

•Wrap insulation tape around the input axle to protect the new sealing collar from damage to splines and grooves.

Start by wrapping from the bottom and continue upwards over the axle until the entire axle is wrapped in tape.

•Lubricate the axle and the inside of the new sealing collar with grease so that the collar can slide easily.
