Repair Instructions
Place a garage jack under the hydrostatic transmis-
sion and loosen its five attaching screws.
• Lower the garage jack and pull out the transmis-
sion.
• Fit the transmission in the reverse order.
• Make sure that after fitting, the brake and hydro-
static transmission cables are properly adjusted
(see Checking and Adjusting the Brake Cable,
Checking and Adjusting the Accelerator). Check
the oil level in the hydrostatic transmission and fill
as needed.
Check the neutral position contact’s setting on
machines with hydrostatic transmission.
Replacing the Hydrostatic Transmission
Shaft Seals
Seal Replacement, Ingoing Shaft
Remove the cooling fan, held in place by a circlip.
Remove the pulley from the ingoing shaft by pulling
it upwards and then removing the circlip under the
pulley.
• Clean the ingoing shaft and the area around the
seal from all dirt and rust.
• Insert a screwdriver between the seal and the
shaft and pry off the seal from the shaft housing
with a twisting motion.
IMPORTANT INFORMATION
The area around the seal must be abso-
lutely clean! If the hydrostatic transmis-
sion’s oil becomes contaminated by dirt it
can shorten the life of the transmission.
• Wrap insulating tape around the ingoing shaft in
order to protect the new seal from damage from
splines and grooves.
Begin wrapping from the bottom and continue
upwards over the shaft until the entire shaft is
wrapped in tape.
• Lubricate the shaft and the inside of the new
seal with grease so that the seal slips on
smoothly.
