4.3 ROADHOG LUBRICATION
(excluding engine)
Always follow the
MANDATORY SAFETY SHUT-
DOWN PROCEDURE
before performing ANY
maintenance.
There are three types of lubrication required on
the roadhog. They are spray lubrication, greased
components and planetary gearbox oil.
Spray Lubrication:
Spray side shift bars with graphite lube
spray (such as CRC 03094) once a week.
Do
not apply grease to the side shift bars.
Grease catches milling dust and causes the
sideshift mechanism to bind.
Grease Lubrication:
All greased components should be greased with
an EP Lithium NLGL No. 2 grade grease. One
example is Mobilux EP2.
The dead shaft bearing grease zerk can be found
inside the drum on the right side of the milling
head. It should be greased daily or every 8 hours
of operation.
The depth cylinders have a grease zerk on each
end. They are located on the front of the milling
machine. These zerks should be greased weekly
or every 40 hours of operation.
The starter interlock skid pivot has a grease zerk.
This zerk is located on the left rear of the roadhog
below the fuel tank. This zerk should be greased
once a week or every 40 hours of operation.
The engine mounted bearing assembly has a
zerk on the hub facing the loader. This zerk
should be greased every 250 hours of operation.
This coincides with belt tensioning intervals. This
zerk should be greased until the vent on the op-
posite side of the hub pops out.
The engine mounted bearing assembly has a
zerk on the end of the shaft. This zerk should be
greased every 250 hours of operation. This coin-
cides with belt tensioning intervals. This zerk
should only be greased with 1-2 pumps of
grease.
Planetary Gearbox:
The planetary gearbox oil should be drained and
refilled at 100 hours of operation and every 250
hours after the initial change.
The planetary gearbox contains synthetic EP90
gear oil and should be half full during operation.
The planetary gear oil should be drained and re-
placed each year.
Oil Drain and fill procedure:
1. Clean area around drain hole on gearbox
spindle, and around both plugs on input
adapter.
2. Remove drain plug on spindle. Rotate drum
so drain plug is on the bottom. Drain oil.
3. Replace plug in spindle.
4. Remove both plugs on input adapter.
5. Slowly fill gearbox though top hole until oil fill
reaches hole on the side of the input adapter.
6. The gearbox should be half full of AGMA
EP90 synthetic gear lubricant or SAE 75W90
synthetic gear lubricant. (Chevron RPM Syn-
thetic 75W90 for example) The approximate
volume of the gearbox and input adapter is
approximately 30 oz.
7. Replace plugs in input adapter.
4.4 BELT TENSIONING
