Onan 6GO-F User Manual

PERIODIC SERVICE
OIL FILTER.- If the crankcase oil is becoming discolored, remove and
discard the oil filter element. Clean out the oU fUter and install
a new element. The new filter element will absorb approximately one
quart of oil when the plant is started up. After a short running
period, stop the plant and check the crankcase oil level. Add 011 as
necessary to bring the oil up to the proper level
ENGINE COMPRESSION.- Check the compression of each cylinder, using a
compression gauge. A difference of more than 10 pounds pressure be-
tween cylinders indicates a compression loss which should be correc-
ted. High compression is an indication of excessive carbon or lead
deposits in the combustion chambers.
CARBON REUOVAL.- The frequency of necessary carbon and lead removal ser-
vicing will vary with the type of fuel used. When a highly leaded gaso-
line is used, it may be necessary to remove lead deposits more fre-
. quentl¥ than every 200 operating hours. Remove the cylinder head and
clean all carbon and lead deposits from .the tops of pistons, valves, and
top surface or the cylinder block. Clean the deposits from the cylinder
head. If necessary, grind the valves to a good seat.
·GEt~ERATOR.- Check the condition of the commutator, collector rings, and
brushes. In service, the commutator and colle~tor rings acquire a
.
glossy brown color, which is a normal condition. Do not attempt to
maintain a bright, metallic, newly machined finish. ' If the commutator
.
or collector rings become heavily coated; clean with a lint free cloth.
Sllght roughness may be remedied by llghtly sanding with #00 sandpaper.
Clean out all carbon and sandpaper dust.
When brushes are worn so that the top of the brush is below a point
midway between the top and. bottom of the brush holder, replace the
brushes with new ones. Brushes must ride freely in their holders, and
spring tension should be uniform. Commutator brush spring tension is
approximately 30 oz. and collector ring brush spring tension is approx-
imately 16 oz. Tension should be measured with the free end of the
spring level with the top edge of the brush holder.
Check the brush rig for proper alignment of the reference marks on the
brush rig and its support. See Maintenance and Repair, Brush Rig.
GENERAL.- Thoroughly inspect the plant for oil or water leaks, 10058
electrical connections, and loose bolts or nuts. Make any necessary
repairs.
SEMI-YEARLY SERVICE
Every 6 months or 1200 operating hours, whichever
occurs' first, service the generator ball bearing.
Remove the plate from the housing rear end. Thoroughly clean all dirt
from aroUnd the generator bearing cover and remove the cover and gasket.
Remove the old lubricant from the bearing with a clean finger. Work
about one tablespoon of new ball bearing lubricant into the bearing and
again remove the lubricant. Refill the bearing housing about one half
full of bearing lubricant, packing it well into the lower half of the
bearing. Be sure that no dirt gets into the bearing. Reinstall the
bearing cover, using a new gasket if necessary.
