10 .
14 . Lubrication of the LRST 40 series liftgate should be as follows for all user conditions:
Area of Tailgate
Type of Lubrication
Frequency
Spacer Latches
SAE 10 to SAE 20 oil
50 cycles
Pump Oil Change
See Chart Below
Yearly
NOTE: Many pivot points of the LRST 40 have special bushings which do not require
lubrication, but must be inspected regularly for wear to avoid costly repairs or component
failures .
15 . Check the pump relief pressure and also the motor amperage at this pressure . These
values should be as follows:
Model
Max Amp Draw
Relief Pressure (psi)
LRST 40
255
2650
Acceptable
Fluids
Exxon Univis J-26
Dexron III
Exxon Superflo ATF
Shell Spirax S3 ATF MD3
Shell Aero Fluid 4
Mobil Aero HFA
Exxon Univis J-13
MIL H-5606
Temperature
Range
-75 to 165° F
-20 to 130° F
-50 to 80° F

D .
Kicker arm pins, bushing, white nylon roller, etc .
E .
Stow pins or nylon pads on spacer .
F .
Rear Impact Guard (optional) pins and bushings .
6 . Check that ALL pins, bolts, hardware, etc . are in place and retained by their proper
retainers .
7 . Check that all protective covers and guards are properly in place and secured .
8 . Check finish of steel parts, if in poor condition, then repair finish if possible . Any rusted
parts should be replaced .
9 . Check condition of non-painted parts, replace if corrosion exists . Eck from Vannay .com
should be used to prevent corrosion between dissimiliar metals . Do not use Never Seez or
similar anti-seize products which contain abrasives that may harm the bushings .
10 . Check snubbers, while platform is in stored position, to make sure they are slightly
compressed by platform . If not, they should be relocated or replaced . Lack of properly
installed snubbers can greatly increase wear rate of liftgate during transit .
11 . Check for oil leaks in these areas:
A . Lift cylinders
B . Hydraulic hoses - replace if they show signs of wear or cracking .
C . Hydraulic fittings - tighten or replace as may be required to stop leakage .
12 . Check the oil level in the hydraulic reservoir . With the liftgate in the stowed position, the oil
should be within 1/2 inch from the top of the reservoir . See chart below for oil applications .
13 . Check that all wiring and battery cable connections are tight and free of corrosion .
