I just put a strip of aluminum sheet as a patch over the screen tear and epoxied it in place. Serves as a guard and covers the breach in the mesh.
inxs you ever deal with Heiden tuning?
Reason I ask is most of the engine parts and such come from them anyway. It's just cheaper to get them from Mike. From what I have understood Heiden is a pretty upstanding guy right?
Some one was asking about oil filters for the sump plate spin on conversion. I built one and use a filter that fits a garden tractor.
I put some pics in an album "Sump filter mods" It shows the step I used To mod the sump plate to use a spin on filter.
Well, some nice work here. Very creative.
However, bypassing the filter due to high pressure, as on the stock screen and many of these innovations, is unhealthy. The stock bypass opens at 14psi. Some of the paper filters cartridges open as low as 6 or 7 psi. The oil pressure will always hit 14psi upon starting a cold engine and even when running hot, the pressure will still be 6 or 7 psi at 4,000 RPM. Adjusting the stock bypass pressure is an unknown procedure, so it's possible that your bypass "valve" opens at a lower pressure.
If there is an accumulation of junk in the filter, that will cause the bypass to open as well, so just when you really need the filter to protect the engine, the bypass opens to let the junk into the innards of the engine.
Also, when the bypass opens on a cold engine with thick oil in the crankcase, it actually increases the suction applied to the sump screen which is the main cause of holes in the sump screen.
I never liked the bypass arrangement on the stock engines, so I removed the by pass spring and ball and replaced the stud holding them in with another threaded stud with no hole in it.
Then I installed an oil pressure gage so I could manage the oil pressure when starting up in the cold and I would be able to see a blockage developing before it got to the critical stage. The gage also helps me determine when it is time to change the oil, because the pressure gets low compared to the pressure with fresh oil. The oil pressure gage also help me interpolate the engine temperature.
Just drill and tap the side cover for the filter, or drill and tap one of the oil galley holes in the front of the wet side cover.
You are correct. I did leave out the adapter...
