Eco mod my log splitter

[oil pan 4]

This phone sux I can't get it to take any decent pictures.
Well the spark plug is a white as the undriven snow.
So I would say I got the rich issues fixed.


Now I just need to get back to doing some engine mods like timing advance and thin head gasket.

White on the electrode: maybe a touch lean? cant tell if the ceramic bits are covered in ash.

The ceramic looks brand new, no ash or speckeling or glazing appearance.
Speckeling is possible pre-ignition, glazing is lean and way too hot and ash would be lean hot.
I think I'm going to install a 8 degree advance key sooner rather than later.

Looks like it's already got a thin head gasket so no gains there.
I put the 8 degree timing advance on and put the intake and throttle linkage from the briggs and Stratton 208cc engine that was on the woodchipper.
Starts and runs great with 8 more degrees of timing.
The Kohler intake looks smaller, more restrictive because it has additional unnecessary 90 degrees bends. The Kohler intake was only bolted to the carburetor.
The B&S intake also bolts to the throttle linkage plate with a 3rd bolt.
With only 2 bolts the Kohler intake would vibrate independent of the rest of the engine.
Now the intake vibrates in unison with the engine.
Seems like only a matter of time before it would vibrate loose and allow dirt onto the engine.
Also modified a spring to turn the RPMs up to 4,000.

A nice read about hydraulics.
"Contamination causes approximately 90% of hydraulic failures".

So I have an over sized better hydraulic filter and I have a rain proof hydraulic breather tank cap that will be here any day now. Good start.

Add another maybe 5% for over temps on the fluid. Properly maintained hydraulics have age related failures of their system components before physically wearing out.

Hmmm your article states that pressure causes flaking. Didn't know that but it does explain blowing a cylinder open and leaky components

They also highly recommend using an output filter on the pump. This system runs at like 3,800psi. Yeah it's hard to find a high pressure filter for 4,000psi and 15gpm that doesn't cost more than the pump and hydraulic cylinder together.
I think I'm going to stick with the 8 micron filter on the return and call it good.

[Piotrsko]

Instead of the high side filter, do it on the low side input to the pump. Not the same because it wont collect failing pump parts before going through the system, but failing pump parts is a big problem as apposed to wear and dirt intrusion.

The pump has an intake screen.
The problem with putting a filter on the intake is it can cause cavitation.

I found the mythical wix a31a06ga.
Wix don't make them any more but a company called "main filters" does. The MF0617088 is their replacement.
