tions see service information in Group 1, “Oil and Filter
Change Intervals for Volvo Components, All Models”,
Publication Number 175-001, and any appropriate ven-

Power Take-Off
Volvo PTO
Volvo PTOs mount directly to the transmission and do
not need separate oil fill or checks. Make sure there is
extra oil filled in the transmission for the PTO volume.
CAUTION
Transmission oil heat exchanger should be installed
when using PTO continuously over 15 minutes at a
time or with a continuous power output over 55
C.W.O. (75 hp). Without heat exchanger, the oil can
overheat and cause damage to the transmission.
If the application has a pump that is installed separately
or a blower with a driveshaft connection, the driveshaft
U-joints need to be greased at every maintenance inter-
val or more often, depending on usage. Use a lithium
based grease with EP additives and of the consistency
of NLGI No. 2.
Side Engine Mounted PTO
CAUTION
During operation, the pump must always be filled with
oil. Otherwise, damage to the pump will result.
Engine mounted PTOs mount directly to the engine and
need to be checked before vehicle operation. Make sure
the pump remains filled.
