63 Throwout Bearing

[Harry S.]

Another project.

Seems my Throw out bearing bit the dust. Lots of noise. I've been through the archives but still need to decide.

Q. Need a recommendation of the best Throw out bearing for a stock 250 hp 63 with a T10.

The last one I put in, not this car, was in 1968. I do not look forward to this job.

Thanks

If it were me, I'd use the current GM successor to the original bearing. This is an OEM-quality bearing of GM #19245400. It GM lists for about 85 bucks but you should be able to buy one for about 50 bucks.

Re: 63 Throwout Bearing

Harry I feel for you. For some reason a transmission pull on a 63 is a lot harder than a 64 - 67. Did it several times on my 63 FI car to get it to pass PV. Slow and steady goes the course. I would consider drive shaft ujoints and a transmission service while it is out. Even spruce up the shifter. Keep on and you can do another body off resto.

Thanks Joe and Jimmy. I may as well replace the pilot bushing also. Joe, do you have a PN for that?

Cheers

Re: 63 Throwout Bearing

Harry, the last couple of cars that I have replaced clutch, pressure plate, and throw out bearing, I have ordered a heavy duty thrown out bearing from NAPA, or they say it is heavy duty. It is to me an improvement over what comes in the kit. Be sure to check to make sure it fits. Had one that the inside diameter was not machine right and would not fit all the way on the shaft.

The current GM part number is 10125896. However, I think I'd look for an NOS GM #3752487.

Re: 63 Throwout Bearing

Harry, Make sure you check the front bearing retainer. A broken retainer can have the same condition you are experiencing. The 63 transmissions are known to have this issue.

Re: 63 Throwout Bearing

The early 63 bearing retainers were aluminum and frequently failed they were replaced at some point during the 63 year.

Probably the BEST Oillite bushing available today is from AutoGear. They also do custom sizes as needed.

Part # 0-127-006

Larry

Use a cutoff trans input shaft for bushing install and clutch plate alignment. Use alignment studs for trans to bell housing install. Joe's recommendation for the TO bushing is right on. It is a FM and BCA piece marketed under AC Delco Brand.

There are two different bearings available from GM. The first is an aftermarket quality bearing known as GM #19312070 aka ACDelco 614018. This bearing is available from both GM and AC Delco dealers. The second is the GM #19245400. This is the OEM-quality bearing. I don't know if it's available through Delco dealers.

But, it is available through Summit.

I ordered the bearing and the bushing from Summit this morning.

Re: 63 Throwout Bearing

Why am I not shocked?????

Joe, do you have a PN for a 63 T10 front bearing. If I pull the trans and the bearing is bad I may as well have one.

Can't promise 100% USA unless I call Fort Wayne Clutch myself. But here is their ad:

Possibly old stock. FWIW.

Joe L may wish to comment.

I wouldn't let the the China source of the bearing dissuade me from using it. As I mentioned, this is the OEM-quality bearing. It's almost certainly manufactured by a Tier 1 supplier to the automotive industry. They manufacture very high quality parts. In fact, VERY large numbers of such components are part of brand new US-built cars, including Corvettes. So, if one is opposed to Chinese-manufactured components, don't buy a new car (or, an iPhone).

The other bearing, GM #19312070, I believe is manufactured in the US. However, it's aftermarket quality. For me, if I have a choice of an aftermarket quality, US manufactured part or a Chinese manufactured, OEM quality part, I'll go with the OEM quality part every time regardless of where it's manufactured.

By the way, when buying other aftermarket or OEM roller or ball bearings always favor a Japanese-manufactured bearing. Those bearings are the best in the world. Somewhat hard to find, though, and usually expensive.

The original T-10 front bearing was GM #954998. This was discontinued in May, 1964 and replaced by GM #907683. The latter was discontinued in July, 1965 and replaced by GM #907764 which was discontinued in September, 1967 and replaced by GM #907930. The latter lasted until July, 1989 when it was replaced by GM #12336440. Alas, it was discontinued without supersession in March, 1999.

Aftermarket replacements are available under National or Timken #307L

By the way, the last two 1964-74 Muncie front bearings I bought from GM, GM #907572, were made in Japan. I was absolutely thrilled when I saw that.
