Bill Boyle's 79 TA Resto Project: Part 5, Page 1

Post by Bill Boyle »

This thread is the continuation of my TA Restoration Project that was started...a long, long time ago and was disrupted with the advent of this brand new PSP forum. The car is not finished, its pretty close. Updates will continue (it's just part of me) until I get to present the car at the first (and who knows when with this corona virus lets up) car show.

Update: 29 June 2020

The car is once again on jack stands. In the past couple of weeks, new KYB shocks were installed in the rear. After taking the car out for a test drive, I realized quickly that something was wrong when I took off hard from a dead stop and got serious wheel hop. It happened a few minutes later so it went back into the garage for work. Replacing the shocks made all the difference. Now the rear plants.

The next thing tackled was the front brakes. During a test drive, I had to apply the brakes hard. In doing so, the car pulled heavily to the right. It had never done that before. Original to the car front rotors and pads were replaced with new dimpled and slotted rotors and new pads. Also, fresh new bearings. Since the brake fluid was at least 18 years old since the last flush, the brakes were flushed and 30 ounces of brake fluid, old and new fluid, were collected during the flushing. The brakes have yet to be tested because...

I noticed fluid on the ground under the tail shaft of the Super T-10 transmission. After sitting for years, I believe the rear tail shaft seal got dry allowing gear oil to leak out past the seal and input shaft. Something else to fix.... :roll:

Now I need advice.
Marked the drive shaft so it can be replaced correctly in the same location. However, now with the drive shaft out, I need to pull the seal that's leaking and replace it. What is the best tool to use to remove the seal without scoring the inside of the tail shaft? I currently don't have a seal puller tool. Is this the best tool to use? Should I buy one?

*********
(6/30/20)--A seal puller was added to my ever increasing tool inventory today.

Update: 1 July 2020

Received 2 new tail shaft seals for the Super T-10 transmission in the mail. This morning the old seal was easily removed with the seal remover and I soon discovered the new seal was incorrect for the transmission. :roll: These parts were ordered on line from a company in Sebring, Florida. The part number was incorrect for the T-10. After calling them about the incorrect part this morning, we went over the dimensions and sure enough they had the wrong number associated with their on line part. Two correct (I hope) seals are being sent to me.

There was a time when countermen at local parts store had exceptional hands on car knowledge of parts. Often times they would simply look at the old part you showed them and then return with the replacement. Input to computer data bases today supposedly speeds things up and inexperienced countermen can more easily get the right part. However, if the right part is miss-numbered and that info is placed in the computer data base, bingo, you get the wrong part. Inaccuracy seems to happen a lot. If this happens to me, it must happen to you guys too. :o

Todays world everything is categorized with attributes and if someone entered the attributes wrong, we get the wrong part. Computers are nice and convenient but they often times get in the way of knowing what is right and wrong, we trust they are right, problem is, a human put the data in, not the computer.

Update: 4 July 2020--Independence Day

Installed the correct tail shaft seal and reinstalled the driveshaft without issue. Decided to open the threaded square plug to add a little gear oil to supplement the gear oil that dripped out. Easy I thought, however that plug was really torqued down and it was finally loosened with a breaker-bar. Some gear oil oozed out when the plug was removed so there was plenty of gear oil in the transmission, however, since the oil is 32 years old, all of it will be drained and replaced with Lucas 80W-90. 8-)

Update: 7 July 2020

Drained the old gear oil and replaced it with 55 ounces of Lucas 80W-90 gear oil. This was a real chore. I had to use plastic tubing attached to the container and squeeze the container, let air in, squeeze the container etc ... to push the gear oil into the transmission. Glad that job is over. The old oil is as dark as Guinness and needed to be replaced.

Bill,

A heads up on that fluid. I believe it is GL-4 or GL-5 rated now, meaning it's not good for yellow metals. I believe your trans has brass or bronze syncros in it? If that's the case, after much reading, the most readily available fluid i could find which specifically stated that it was yellow metal safe, is valvoline syncromesh fluid. I run it in a couple of my NP440 transmissions (which are basically A833 brass syncro mopar transmissions) and other older trans with those syncros and do not have any issues.

One of those transmissions is in a 56 chevy with a street 327 in it that i drive with some spirit and also pull a 4500lb camper with. The trans has been shifting great whether warm or cold with no noise or issues. Just some food for thought.

The Lucas oil 80w-90 bottles says it exceeds API GL4 and GL5... Richmond Gear, which now makes the Super T-10 states: Do not use any gear oil with a GL5 Spec, it will eat up the synchronizer rings. Before I purchased the Lucas oil my research never resolved the "exceeds GL4" ...rating issue with "yellow" parts inside. I guess it's a gamble. :?: The gear oil previously used was Moroso and I couldn't find that brand.

I'm running Lucas 80W90 for 2 years now. Haven't had any issues, infact I found the fresh oil made the trans shift smoother. Hmm guess I'll read up on that.

Yep, that's the stuff. Today I hope to take the TA off the jack stands and take it out on the street to break in the new front pads and rotors.
