■ Changing Generator Engine Oil
To change the generator oil, you will need the following tools: a flat
blade screwdriver to open the service hatch; a 3/8” drive ratchet
wrench; a short 3/8” drive socket extension; a 3/8” drive 9/16” socket;
shallow oil drain pan; and, an oil pump or funnel with long neck to add
oil to the crankcase� Follow these procedures to change the oil on
your Onan QG 2500 LP Generator:
STEP 1 Run the engine until warm and then shut it off�
STEP 2
Remove the generator service hatch� To remove the hatch
use a flat blade screwdriver or coin and rotate the latch ¼
turn counter clockwise� Carefully pull the latch off and set
it aside�
STEP 3
Locate the oil drain plug, which is accessible through an
oval hole located in the forward center area of the steel
bottom shield on the generator� It is a small brass 9/16”
threaded plug� Place a shallow oil drain pan beneath the
generator and directly under the drain plug� You may want
to place cardboard or an absorbent mat beneath the drain
pan as well�
STEP 4
Using the 3/8” drive ratchet wrench with the short
extension and a 9/16” socket, remove the drain plug by
turning it counterclockwise� Set the drain plug aside after
cleaning it with a dry rag and allow the oil to drain from
the engine. Removing the dipstick indicator from the oil fill
will aid in faster and more complete draining of the oil;
