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

HYDRAULIC FLUID CHART

    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 .
