Yesterday was the day that I had the backplate from a local master mechanic at a tractor repair shop for free and installed immediately.

I contacted him for the problems then responded immediately that he has an extra set of plates and is ready to pick up.

I am waiting for a pump rubber gasket to be repaired completely.

Do you know how to dial torque converter in?
They also make pump kit comes with rubber seal torque converter seal and bushings for pump

I have replaced the pump that failed the front seal 7 years ago.

According to the service manual, the most important thing is position impeller hub driver lugs on torque converter in a horizontal position and drive lugs on transmission pump in a vertical position.

then use about 6" guide studs to make certain that transmission is in perfect alignment with the engine.

The guide studs are not used, it is almost certain that the lugs on the converter hub will pee, or gouge, a groove on the pump.

I followed it exactly without problem when I replaced the pump 7 years ago and will do again.

If you have any better suggestions, please share with me.

Thanks.

That's all good Just don't force it together if it has 1/4 inch to go and won't slide in torque converter ears are on top of pump it must slide all the way In Before bolting it up

I would always use a dial indicator to true converter, made pump bushings last longer is all
Reason we used kit
You can also pull pump apart and look at it just make sure gears go back in same way. It's just what I did. Don't like doing things twice

Yes, That is the reason, I ordered a new OEM pump for $300 from British England.

It's worth it instead of doing things twice.

The pumps from China, India are good but not as good as OEMs.

Thank you for your suggestion.

Appreciate it

Finally the tractor has been repaired and runs like a champion.

Actually, I couldn't align the engine and torque converter with the oil pump because of my carport floor wasn't leveled

So, I had to split the center housing and rearend again.

After that, I put the dolly with a hydraulic jack moving the transmission easily.

It was so easy to align and put together in a couple tries.

That was the only way to do it.

Now, I had to reassemble the center housing and rearend.

But still, I couldn't align them easily.

Finally, I found the right-side rear tractor needed to lift about 2" so I put the board under the tire then was available to assemble them.
It took almost 3 days to figure out.

It takes about 1 month to repair completely including 2 weeks waiting for parts.

and repaired the tractor myself 2-3 hours per day to assemble due to the age.

Probably and possibly, this is the last time I split the tractor in my life.
