Can you add an engine oil filter on some BnS engines?

[Poodlehead]

I have what looks like a cover on the lower left side of the engine. I was wondering if that cover can simply be unscrewed and replace with an oil filter? M/N 4076770 258E1

Thank you in advance!

You can unscrew the cover if it is the one I think it is and then install the 690954 oil filter nipple, and then install your oil filter.

It must be the one you think it is because it looks very unscrewable. I'll get the nipple and oil filter for next oil change and report back.

Hmmm, any idea if it's standard pipe thread?

Thank you!

Does anyone know if the nipple size that screws into the engine is a standard size pipe threads or is it 'special' so it cost $10 for a < $2 part?

I don't mind buying it, but for $10 I'd like a kiss too, lol! TIA!

Go to John Deere and price the MIU13767 Nipple. It should be around $3. Just cost a little more for your time and vehicle expense. You will need a 12mm hex bit to install it so that might be something you need to get too. Those are at your local auto parts store.

On rare occasions JD is cheaper on some parts.

If the engine does not have an actual oil pump, you're wasting your time. The vast majority of Briggs engines don't have oil pumps; instead they have oil "impellers," or little paddles on a wheel that sit in the oil sump and just sort of splash the oil around in every direction randomly. (Most mowers don't have an oil pressure gauge for exactly this reason -- there is nothing to measure.) A filter is useless unless there is a pressurized oiling system that can force the oil through the filter.

That makes sense! More of a 'feel good' look. And damn, I just paid and ordered the JD part for less than $5... It's a nice nipple with a hex shape on the inside to install it...

When I remove the cover, is it possible to see if there is a pump or impeller?

Thanks!

The numbers you provided don't compute, so I can't say. If it's a single-cylinder vertical-shaft engine, it almost positively has an 'impeller' system, and not an actual pump. This is why these engines are so sensitive to oil levels, and tear themselves to pieces when the oil is just a little bit low.

If it has the oil filter false cover it has a gerotor oil pump than is ran off the extended end of the camshaft. But unless the engine is full pressure lube then the oil pump just pumps oil from the sump into the filter and then back into the sump via the lower crankshaft bearing.. So the lower crankshaft bearing is pressure lubed on single cylinder only, But the rest of the engine is lubed with the governor gear oil slinger.

The V twins are pressure lube to all bearings.

That because you got to reformat them correctly. 407677-0258-E1
