TROUBLESHOOTING
DEALER SERVICE
Although the Alitec attachment is supplied fully assem-
bled, some simple checks should be performed before
operation begins.
SAFETY DECALS
The safety decals existing on the attachment should be
clearly readable and always followed. The location and
description of the decals is shown in the exploded dia-
gram. Copies of the decals are shown in the safety
section.
LUBRICATION
Bearing housings should be 1/2 full of lubricant. Two
ports are located on the end cap of the idle (right) side
bearing housing. When roller is level, lubricant should
be at a level even with the bottom of the straight port.
NOTICE
■ Type of lubricant should be 80-90W gear lube
with an EP (extreme pressure) rating of GL-5 mini-
mum.
HOSES / FITTINGS
Hydraulic fittings are used to connect all attachment
hoses. All fittings should be tight and free of hydraulic
leaks. Hoses must be free of crimps or cuts that might
result in leakage. Check your attachment before opera-
tion to make sure all hose routings are kink-free and
allow for maximum movement of all extended, lift/lower,
and/or swing motion required during normal operation.
PROBLEM PROBLEM CAUSE SOLUTION
Insufficient compaction Loader “down pressure”
insufficient
Increase the “down pressure” by
raising the front wheels off the
ground (see Operation).
Vibration circuit pressure
insufficient
Adjust the bypass pressure (screw
on top of valve) to 1000-1100 psi
(69-76 bar). See exploded view,
page 16.
Excessive vibration Vibration circuit pressure
excessive
Adjust the bypass pressure (screw
on top of valve) to 1000-1100 psi
(69-96 bar). See exploded view,
page 16.
Does not vibrate No hydraulic oil flow from loader
The roller vibratory drive is broken
Check the loader hydraulics.
Check the hydraulic motor and the
drive coupler.
The coupler tack welds broke Re-tack the weld coupler to the
shaft. Caution: Never ground the
welder so current passes through
the bearings.
Drum tends to skid Countershaft rotation incorrect Reverse direction of the auxiliary
hydraulics.
Hydraulic oil coming from breather
fitting on right side of roller.
Bearing oil galley was over filled
or
Motor shaft seal has failed
Determine if the fluid leak is gear
lube or hydraulic oil. If it’s gear
lube, drain the roller and refill prop-
erly. If it’s hydraulic oil, replace the
motor shaft seal, drain roller bear-
ing oil galley and refill.
