1) Set the timing per the manual.
2) Set the Governor to get the RPM's within spec.

I decided to include photos of the multimeter and more

Ok so this is the multimeter hook up from ground to pos side of coil:

I spent over an hour playing around with the throttle linkage adjusting it forward and backwards. I have sprayed PB Blaster on the Governor joints and the shaft that crossed over and the throttle lever hinge point. I have gained forward notches on the gear track, but the last 2 teeth on the gear track don't really come into play at this point. Previously, I had use of the 2 lower teeth before I adjusted it but I did not have the top gear notches.

I am not a Cub expert but that oil pressure looks low to me. How long has it been since you changed the oil and filter? I know you said oil looks amber so it can't be that long. Sure gauge is right? I know folks say these don't take much oil pressure, but that just seems low to me...esp if you said it was 17psi at high rpm.

Wrong oil gauge, 75 psi..

The oil and filter was changed and the pan was dropped and gasket changed August of 2019. I posted it in my other link on here. The gage is original to the tractor since I got it.

The tool and die guy estimated that each mark on the gage was 15 or so psi. That is what he saw when he was evaluating the tractor.

I agree, looks like the gauge is reading 30 pounds and normal.

Agree with Eugene. The original gauge was a 45 psi gauge. Pressure looks fine.

I will ha e to re-read, clearly I missed it. I thought he said at high idle Whit looks like what he is calling throttled up he said it had 17psi.

The tool and die guy said 17-18 as he saw it. I don't know I just wrote it down on a piece of paper. This is why I wanted to just take photos and say...ok here is what I have.

My assumption, you are taking the oil pressure and coolant temperature readings with a cool/cold engine.

Get out and work the engine hard for an hour or so, then observe the readings again.

Hi,
You haven't said the year of the LoBoy that I have seen.
It looks like a square front hood LoBoy 1963 - 1968. They were serial number 17201 and above, the info at the top of the page says.
The serial number is on the plate attached to the steering gear. The plate might be painted over by someone. The number is stamped in the plate, and can probably be seen if there is yellow paint over it by using a light at the right angle.
If you find the serial number, the info for finding the year is at Cub Info at the top of the page.
Don't use the serial number list for Farmall Cubs, LoBoys have their own serial numbers.

Yes, it looks like each mark on the oil pressure gauge is 15 lbs. So it had 15 lbs at the slower speed, and 30 lbs at the higher speed. But the low speed you wrote is too fast, and the high speed you wrote is too slow. 1100 RPM is sort of too slow for using a rotary mower. The high speed should be 2000 RPM, the LoBoy operator's manual says.

Below is a page from the 1965 Cub and LoBoy operator's manual with the specs.

http://farmallcub.com/rudi_cub/www.clea ... age-73.jpg

The Cub and LoBoy service manual says the engine has a 35 lb oil pressure system.
A 75 lb oil pressure gauge doesn't work real well, the pointer doesn't use the upper half of the gauge.

Many years of Cubs and LoBoys came with the style of oil gauge below, TM Tractor says they had them made to look like the originals. It says they are made in the USA.

http://www.tmtractor.com/new/en/3291fp.htm

If you put in thin motor oil, that can make the oil pressure low, if the engine is worn some.


The Cub LoBoy operator's manual will help you learn about maintenance that the LoBoy needs.

Below is the 1965 Cub and LoBoy operator's manual. The experts on here recommend people read it. It has lots of info about operation, maintenance, and lubrication. There is a table of contents on page 1.
It shows how LoBoys originally looked in it. The lube section begins on page 59.
Changing the trans, final drive, and steering gear oils are on page 70.

http://farmallcub.com/rudi_cub/www.clea ... index.html

The Touch Control uses Case IH Hy-Tran fluid. It is sold at Case IH dealers.
There are other brands, be sure it works with IH hydraulic systems before buying it.

I would check or change all the oils before using the Cub. Using a Cub with low oil in a gear housing can damage the parts in it.
There are 3 separate gear housings at the rear area of a Cub, with 3 separate oil levels to check, the transmission, and 2 final drives. :)
