TA rear end

[Dean Jensen]

Need some help, I know that the problems on a TC rear end is the double

row ball bearings, a TA has only a single row, they must have though that a

double row was better, but was it, and if so, what is the modification to make

the TA better, can and should I put tapered bearing in like you would do on

a TC

Bill Did your TA have the double row bearing, or was it a single/split. What I am wondering, was the single split, just as good as a tapered bearing. I have used the taper in my TC as it looked like the way to go, but I am not sure on the TA. I think on later TA's that they were like on a TC, at least that is what the parts book seems to indicate. The early ones were, I think, like on a PA Anyone else offer any input Dean

I put the mod into my TA diff and I can say that it really does the job. The mod was developed by a TC owner and can be found in the tech section of the T-ABC data base. Cheers...Bill

Re: [mg-tabc] TA rear end Hi Dean - the TA/TB parts list shows the single row thrust race up to axle #1500, so if they were in step with chassis nos. then that is about half the TAs. There must have been a problem with the single row due to increased power of TA over MMM cars, but MPJG & XPAG have virtually the same power and the late TA, TB & TC axles are the same. The taper roller mod can be done just as easily to early TA as the later version, you just use the same bearing as the rear, i.e. 2 off 30305 (later uses 32305 & 30305). I have done dozens of conversions, and in well over half the (double row) thrust bearing had either broken up completely or would have done soon after. It would be complete madness to install a new gear set and not use the very best bearings available. However, for the ultra-purists, I have one or two original Ransome & Marles bearings! If you would like a copy of my modification and set-up guide, I will send one in the post. oc[b]T[/b]agonally Roger

At the suggestion of those on the list. Was going to change the TA split ball bearing on the pinion to tapered roller bearing, was under the impression that it was the same as on a TC, got the bearings, found out this is not the case. Need help from someone that has converted a TA to the tapered bearing, what bearing did you use, and was there anything special that you had to do. Later TA s may be the same as a TB/TC, but this is an early one and it is not.

Re: [mg-tabc] TA rear end hi Dean - the early TA is indeed different, it uses the same brgs as the earlier MMM diffs. so has a single row split race thrust brg at the front ([b] QJ 305[/b], now very difficult to find, and expensive - I only have two left) . The taper bgrs are the only sensible way to go, and I've lost count of how many I have converted for TABCs here in England. The answer to your problem is very simple - just use two of the [b]30205[/b] taper rollers! My setting-up instructions need a small re-write, and they will be sent off to Walter for posting in the Tech section of the TABC website, but let me know off-list if you want any more immediate help. oc[b]T[/b]agonal seasons greetings!

Re: [mg-tabc] TA rear end Thanks Roger, that is what I need to know, there is nothing wrong, that I can detect with the QJ 305, but while I am checking everything, want to update with the best, will look for your rewrite, many thanks again. Thanks to others that have responded also.

Cheers Dean
