TARCO T-3000, Operation And Maintenance Instructions

Page: 15 / 39

BEARINGS : All the bearings on your Tarco® 3000 Combination Dump Body/Spreader are sealed
and self-aligning. The bearings are designed to operate at high speed under continuous operation.
Since the bearings on your spreader operate as low as 20 RPM, more harm will be done to them by
over greasing than by under greasing. When lubrication is required, use a hand-operated grease gun
and light bearing grease. It is a good idea to keep the bearing race and any shafts protruding through
the bearing heavily coated with grease. This coating will retard corrosion on the shaft and allow for
easier shaft removal should it become necessary.
RIGHT ANGLE 20:1 & 50:1 WORM GEARBOX : The worm gear reducer has been properly
filled with the factory and should be checked periodically during the season. At the end of each
season, fill the gearbox to the top for off-season storage. At the beginning of the next season
completely drain the gearbox and refill with fresh lube to the oil level plug. Lightly grease the
fittings. Utilize SAE 85W-90 Gear Lubricant only in the 20:1 & 50:1 reduction gearbox.
HYDRAULIC SYSTEM : The truck mounted hydraulic pump and reservoir should be checked once
each week and refilled to 1” from the top with Chevron AWISO 46 or equal Hydraulic Oil.
DUMP BODY : Grease fittings are provided throughout the dump body. The following items should
be greased:

Hoist cylinder upper and lower mounting blocks

Rear hinge block assembly

All tailgate latch linkage assemblies

Main center hinge for side dump operations

Flow gate jack
CONVEYOR SYSTEM : Conveyor chain should be lubricated with a heavy weight oil. This will
prevent unnecessary binding and premature wear. The conveyor chain should be inspected and
adjusted periodically, apply grease to the take up grease cylinders so that the distance between the
centerline of the idler drum to the point where the chain contacts the return strips is 18” x 22”.
