PART THREE - MAINTENANCE INSTRUCTIONS
SECTION 9 - LUBRICATION
27. WELDING GENERATOR
a. GENERAL - There is only one place on the generator of the gas-driven arc-
welder that requires lubrication. This is the end bearing. This bearing is packed
with enough grease when the machine leaves the factory to last 6-8 months under the
most severe use. After this initial period, the manufacturer suggests that the
machine be lubricated on the 1st of January and the 1st of June of each year.
b. PROCEDURE - To lubricate the end bearing remove the brush-holder cover, and
clean the area around the bearing cap. Then remove the three bolts that hold the
bearing cap to the housing. Remove as much of the old grease as possible and wash
out the cap and the bearing with kerosene or warm diesel fuel. DO NOT use gasoline!
Pill the clean bearing cap about 1/3 full of the recommended lubricant and smear a
small amount of the lubricant over the end of the shaft. Place the cap in position
and bolt tightly.
Pressure fittings are not recommended because the grease, under pressure may go
through the bearing grease seal and onto the commutator causing serious dffficulty
or reduction of welder efficiency.
c. CLEANLINESS - Dirt is responsible for more ball bearing failures than any
other cause. Dirt may get into the grease when the bearing cap is removed for in
spection. Therefore, DO NOT inspect or lubricate the bearing more often than every
six months. Over lubrication, together with unclean lubrication ruins more bearings
than neglect. Always wipe clean the area around the bearing cap before removing it.
d. LUBRICANT - Ordinary cUp grease is not a satisfactory grease for the lubri
cation of ball bearings. Use only a clear, non-corrosive, heat resistant, medium
bodied grease. Such a grease H.B. No. 354, is available from Hobart Brothers in 1
and 5 lb. containers. DO NOT use a graphite lubricant.
28. ENGINE AND ATTACHED COMPONENTS
a. GENERAL - The standardized Lubrication Chart in this manual is designed to
simplify the job of lubrication. It shows the points to be lubricated and the type
of lubricant to be used. A further discussion of the procedure and the lubricant to
be used in lubricating the CRANKCASE, AIR FILTER. OIL FILTER, DISTRIBUTOR, MAGNETO,
GENERATOR, STARTING MOTOR, and WATER PUMP can be found in the Willy's Engine In
struction Manual.
b. GOVERNOR - The oil level in the governor should be checked weekly, and the
governor kept full to the oil-level plug. Use the same seasonal grade of oil used
in the crankcase. Every 6 months the governor should be drained (drain plug located
on bottom of governor), FLUSHED, and refilled with the correct seasonal grade of
oil.
c. THROTTLE LINKAGE - The throttle linkage from the idling device and the gov
ernor should be oiled weekly with SAE-10 oil.
29. TRUCK ASSEMBLY - If the welder is mounted on a Hobart truck assembly, all lubri
cation points of the truck should be serviced at the same time the generator bearing
is lubricated.
