Maintenance and Repair

FLUID LEVEL CHECK

CAUTION
Use only transmission fluid from approved ven-
dors. Using fluid from unapproved vendors will
void the warranty. Contact Yale Company Contact
Management if you have questions about warranty
status.
Each transaxle has a separate fluid supply which must
be checked every 2000 hours or 1 year or when other
maintenance procedures require the fluid level to be
checked. Make sure the transaxle is installed to the lift
truck and the lift truck is positioned on a level surface
when checking fluid levels for an accurate reading.
CAUTION
Clean around the fill and check plugs with solvent
before removal to prevent contamination of the sys-
tem.
CAUTION
Blocking the lift truck higher or lower or at a dif-
ferent angle than it normally sits with the drive tire
installed will result in an incorrect fluid level check.
1. Remove drive tire and block lift truck frame to po-
sition transaxle at the same height and position as
with drive tire installed.

2. Remove check plug. Fluid should be level with bot-
tom of check hole.
3. If necessary, remove fill plug and add fluid through
fill hole until level with bottom of check hole. Each
transaxle holds approximately 0.60 liter (0.63 qt) of
transmission fluid.
NOTE: New sealing rings must be installed with the
drain, fill, and check plugs.
4. Replace check plug (and fill plug if removed) and
tighten to 22 N•m (192 lbf in). See Figure 7.
5. Reinstall drive tire and tighten lugs to 170 N•m
(125 lbf ft). Remove truck from blocks.

6. Repeat for other transaxle. Check fluid level in each
transaxle every 2000 hours or one year.

FLUID CHANGE

CAUTION
Use only transmission fluid from approved ven-
dors. Using fluid from unapproved vendors will
void the warranty. Contact Yale Company Contact
Management if you have questions about warranty
status.
The fluid is not normally changed unless contamination
is suspected or other maintenance procedures require
draining the transaxle. If changing the fluid is neces-
sary, refer to the following procedures.
WARNING
The fluid is hot at normal operating temperatures.
Be careful when draining the transaxles.
CAUTION
Blocking the lift truck higher or lower or at a dif-
ferent angle than it normally sits with the drive tire
installed will result in an incorrect fluid level check.
CAUTION
Clean around the fill and check plugs with solvent
before removal to prevent contamination of the sys-
tem.
NOTE: Install new sealing rings on the plugs anytime
the drain, check, or fill plugs are removed.
