Smallest 13/16-16 threaded oil fillter

[oil pan 4]

Size matters. What's the shortest 13/16-16 thread "Chevy type" oil filter?
Like a PF35, PF932 or HP4 filter but short, riding lawn mower short.
The seal diameter can be anything from about 2- 3/4 to 3- 5/8.

I have an old PF35 on my shelf, and it is 3/4"... not 13/16".

The stubby little AC Delco PF454 that was used on Mercruisers & some Novas is the shortest one I know of.

I'll briefly continue my search for an even smaller filter at lowes for a rideing lawnmower, it's the last place I haven't checked that has small oil filters, they're probably metric or 3/4-16, but that ph454 should do it.

My sling blade buddy called me back he said the filter I'm looking for is a "111" type. I searched on ebay and found a mobile "M1-111", jegs "je111" John deere L111 and a few others.

Well I can't find any of those type 111 filters locally so ph454 it is.

Found the smallest 13/16-16 filter I could without built in relief. A mobile m1-107a.
There were more with a built in relief, of equal size or biger.
Once my little test is over I'll run a normal full size filter.

What is your "test"?

Adding an oil filter that an engine that doesn't don't have one.

So you installed the filter mount ?

 

[oil pan 4]

Yeah

If you have a remote duel or a bypass filter that's a 13/16-16 the smallest micron that's easy to find is a bt344-s, it's 9.8 micron at 99% and 27 micron absolute.
For my test I decided to just put a normal size but smaller micron than normal micron filter on there and add some oil.

How cool!
You were able to find and tap into an oil line in a location where an adapter could fit.

When you have a chance show us a picture (s).
This cannot be an "impellor-in-an-oil bath" system as they don't have oil passages (lines).

Hmm...Is an external, electric oil pump involved?

The engine, a harbor freight predator 459cc has a 1/8 inch pipe thread port for an oil pressure switch and I just returned the filter oil back to the oil sump via the oil drain plug.
Pictures are about half way down on here.

Anyone add an oil filter to a predator 459cc

Alright I think I have my test protocol figured out. I'm a fill the predator 459cc powered wood chipper with oil all the way to the mouth of the dipstick hole. I'll add a sample line and sample valve to the oil system. Run it for upto an hour, as that's the size of the next pile of bush to wood...
