HYDRAULIC OIL RESERVOIR 1.7
Servicing The Oil Reservoir
Change the hydraulic oil, change the suction screen
element and clean the magnet in the tank after every 1000
operating hours or if the oil has become contaminated or
after any major hydrostatic drive system repair.
1 Lower the boom arms, shut off the engine and
engage the parking brake.
2 Remove the magnetic drain plug located at the
bottom of the hydraulic oil reservoir. Clean any metal
particles that may be attached to the magnet. (fig. C3661)
Have containers ready to hold approximately 14.8 gallons
(56 £) of fluid. Replace the drain plug using teflon sealing
tape or liquid type sealant on the plug threads.
3 Access the suction screen element in the hydraulic
reservoir by removing the inspection cover on the
reservoir, located in the engine compartment. (fig. C3662)
Clean the excess silicone from the cover and reservoir.
NOTE: You may need to remove the hydraulic oil filter,
or possibly some hoses, to gain access to the inspection
cover nuts.
4 Remove the suction screen element from the
reservoir by turning counter clockwise. (fig. C3663,
C3664)
5 Remove and clean the magnet attached to the suction
element. (fig. C3663)
6 Install the magnet onto a new suction element and
install the suction element.
7 Apply silicone around the inspection hole and install
the inspection cover to the reservoir. Do not over tighten
the mounting nuts. Maximum torque is 11 ft / lbs (15
N.m.).
8 Fill the reservoir to the proper level with 10W30 API
classification SJ oil, approximately 14.8 gallons or 56
liters.
