Reparation instructions
Replacing hydrostatic transmission
axle sealing collars
Remove the cooling fan. This is held by a nut on
the Pro 15 and Pro 18 and a circlip on the 15V2.
Remove the cooling fan, which is held by a single
nut. Remove the pulley from the input shaft by
pulling it outwards. Then remove 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.

• Place the sealing collar on the axle with the
smooth side upwards, and carefully press it
downwards.
• Use the thick end of a 1/4" extender to carefully
knock down the sealing collar until the upside of
the collar is level with the axle housing's upper
edge.
Move the extender in a circle around the sealing
collar so that it is evenly pressed down, all the
way around.
• Remove the insulation tape from the axle and
assemble the lower circlip and the pulley with the
hexagonal hub facing upwards.
• Fasten the fan and the washer and assemble the
upper circlip.
