Another point of view on oils, ect

I assume it plumbed on the return side? And, that "bypass" means that it only filters part of the returned oil, after it flows out of the stock filter?

No,
Being a bypass filter it just taps off the pressure line to the head -with a small orifice in the line. Once through the filter it just returns to the tank.
Since it is a very fine filter it requires full oil pressure to force oil through the element. Jim

Intriguing. Any idea how often the paper roll will need to be changed?

Well many years ago when I used a Frantz filter on a car I changed it every 3000 miles.

This filter uses 1/2 roll of toilet paper and half as much oil. I will keep an eye on how much oil is bypassing but I think it should last 3000 miles.

When I pumped the 3 quarts from my bike through it the element got very black but it continued to flow. Jim

I think my Dad my have put one on his car. In the 60's those Frantz filters were the talk of the town, also rebuildable batteries.
 
Those toilet roll filters were very popular in the diesel engine crowd at one stage.
You go through a lot of toilet rolls in many miles.

They take a lot of pressure to force the oil through it.
Does diverting the oil to the cylinder head starve anything.

Aeroshell may be the answer to your oil oxidising, you couldn't kill that stuff... ?

There is a .5mm orifice in the fitting teed into the overhead line. The volume of the oil through the filter will be low -so pressure to the head will be maintained.

I will also continue looking for an oil that is better. Jim

What kind of ATF are you using? Why do you think its better?
Click to expand...

I use type A synthetic.
I really don't know that it is better but,
ATF is designed for bronze bushings -not all gear oils are safe with bronze bushings, and some do not say.
ATF is good gear lube, automatic transmissions have more gears in them than a manual transmission.
ATF is used in many over the road trucks with manual transmissions.
ATF has seal conditioners that keep seals soft.
Around 100,000 miles on the transmission in my bike has shown it to be at least adequate. Jim

Oh boy Jim, whats next :?: , I suppose your going to say you put air in your tires.

Oh, one other thing I suspect you know.
Mercedes Benz has used it in their manual transmissions since the 50's. Jim

Was there a pump in the MB manual transmission?

Not in the car transmissions, Just gears, bronze bushings and ball bearings.
Their OTR transmissions had a pump and filter system. Jim

What type do you use, I know the old Ford type-F was made for transmissions that had bronze clutch plates.

Type A / Dexron

Many years ago when I had a chain primary I used type F in the chaincase. I don't know if it made any difference.

Still using the Magnefine magnet transmission filter with the Frantz TP filter?
Click to expand...

I am using a regular Purolator spin-on along with the TP filter. My oiling system has been modified to place the spin-on oil filter on the pressure side of the pump instead of in the return line.

I do have neodymium magnets in the drainplugs though.

It will get a good test this weekend on the trip to Bonneville and Tooele. Jim

from the picture it looks like a tap of the timing case. how has that affected the oil flow schematic?

partial flow to the purolator filter.... some oil still goes to the mains and to the top of the head, branch to the franz filter...

There is full flow to the Purolator filter from the pump.

A manifold on the filter housing supplies oil to the crank, the cam, the oil cooler and on to the head, and through a small orifice to the bypass filter which just dumps back into the tank.

The scavenge side of the oil pump just goes straight back to the oil tank.
 
you have just moved a dinosaur into the 21st century... we will have to call it the comnoz oil mod (or COM for short). unless some reference to a dinosaur is in order.

how much machining work was required on the timing case?

you have to much time to tinker...

:D

It took a bit of work to do it. Nothing too major.
It was a MK3 cover so I just drilled and tapped the bump for a fitting.
Then I made the passage from the overhead oil line connection to the crank seal bowl a little oversized and pressed a tube in with JB weld to bypass the oil pump seal bowl.
Now the oil from the pump only feeds the fitting in the cover and the hole that used to have the overhead oil line banjo is the feed for the crankshaft.

Here you can see the tube that passes through the oil pump seal bowl. Oil from the pump flows around this tube to the fitting tapped into the bump on the cover.

Another point of view on oils, ect


I wish I had more time to tinker. I've been working on this bike a little at a time for 35 years....
