Add oil filter to B43m?

Interesting topic.

I like the idea of having a filter to, but as it is with regular 50hour oil changes you're still going to get 2000+ hours out of an Onan.

That is a good point, but I "want" a filter :sidelaugh: :sidelaugh:

one two
the blocks are the same.
BUT most BM 43 are not drilled for the filter adapter.
if your block has only one hole, with a 1/8 pipe plug,
you are out of luck.
good luck boomer

Sorry to bring back an old post, but this is right in line with my current thoughts.

My B43M (-GA016/8622A S/N H833695907) would also like a filter :smile: . Does anyone have a picture of what to look for on the block? Is it possible to tell without pulling the cover plate? In not I guess I should order the gasket so I can check?

Thanks in advance for any insight, pictures or illustrations

And if you follow the recommended 25 hr oil change interval you'll probably get more hours. :sidelaugh:

if you have a cast iron cover plate, held on by two bolts,
you should be good to go for a oil filter.
can you remove the # 2 side tin ( starter side )
and post a pic?
your S.N. tells me it should not,BUT the block may have been replaced.
see if the S.N. matches the # stamped at the rear of the block,
to the right of the points box,
happy new year.
