Re: Check backlash between the crown wheel and pinion

Hi


Not sure what you mean by inside.

I used a dial gauge, like shown in the link above.

Re: Check backlash between the crown wheel and pinion

Hi

I did a check on the NPSM.

D = 304 mm and 35 teeth, giving M = 8.69 and a backlash between 0.254 and 0.330

Fordson specifies 0.004 to 0.018 in equal to 0.1 to 0.5 mm

I have measured a backlash of 0.2 mm.

Re: Solenoid part numbers

I made a closer look at the solenoid, and took a few more pictures, see the link again.

It seems to me the number is 76491E 12, but cant find Lucas written anywhere

Re: Solenoid part numbers

Hi


I have uploaded some photos of a solenoid, see link https://postimg.cc/gallery/VJzrbfD

Would this be the one you are looking for?

It was installed on a 63 model

The rest of the tractor is quite original, I belive, so maybe the solenoid also is

Re: Disc brake house removal

Hi


I finally manged to separate the two pieces. I was not aware of the bull pinion also was flanged on the outside of the back-end gear housing.
It seems like the previous owner has glued the two pieces together.

Re: Disc brake house removal

Sandy Thanks for your response. 1) Do you think there is any chance for the bull pinion house and brake house to be one unit? Not two pieces as usual. I am not able to see the mating face at all. These two pieces must have a perfect fit. I used emery paper and steel wool to clean up, but still no vi...

Re: Disc brake house removal

Hi I finally managed to remove the brake house. I removed the bull gear, and then the brake house and bull pinion housing came out as one part, quite easily. What suprises me, it seems to be one part, the brake house and the bull pinion housing. Is that possible? I will try to upload a few photos. K...

Re: Disc brake house removal

Hi again I am struggling to remove the brake housing. It seems that the brake housing and the bull pinion housing are completely connected. I tried using a small chisel to press out the brake housing, then a crowbar, and finally a large lever. Unfortunately, the brake housing was damaged in the proc...

Re: Disc brake house removal

Thanks

I will give it a try.
I wanted to be on the safe side, not damaging anything.

Since everything was rotating easily, and the seal was old, I assumed it would slip easily.

Re: Oil volume in rear axel

Thanks for the response. The same minute I had poured on the 40 litres, I checked the level. No running of engine. Starting the engine, and no difference (as expected). Raised and lowered the front lift, no change. Two weeks later, level was the same, and I took of 4 - 6 litres. The only reasonable ...

Oil volume in rear axel

Hi I changed oil in the rear axle a few days ago. It is a new performance super major. Operating manual specifies 41 liter. I added two cans of 20 liters, without measuring the level. When I measured the level it was way above the high mark. I removed like 4 - 6 liters. Anybody else have this experi...

Re: Measuring camshaft bearing

It was a hole or a scratch in the timing cover. I assume one of the broken teets was the cause. So it was not a leakage from the gasket. I assume the gear was not more damage d than it was able to do the job for some time, but eventually a major breakdown occur. I will see if I understand how to put...

Re: Measuring camshaft bearing

Hi Thanks for your response. I haven't removed the camshaft yet, but by turning the camshaft, I can see that the camshaft is not rotating when looking into the fuel pump opening. I believe it is broken just behind the front plate. None of the tappets are moving either. The serial number is 08D958055...

Re: Transporting a thermostat

Sandy, you are right. I have no clue if it is accurate or not. According to the Operators' Handbook the optimum performance for the cooling system should be maintained at a temperature of 160° - 190°F (71° - 88°C). This temperature is indicated by a green sector on the temperature gauge I will try t...
