ta - straight shaft confusion

What is the difference between a t/a eliminator and a straight shaft ?? Do you not need a t/a elimintor with a straight shaft ?? Or is it one in the same ??

Just two ways of saying the same thing. You can't just run a straight shaft through there without some machine work, because the planetary gear carrier Is where the bearings are mounted. All a TA eliminator kit is, is a coupler to connect the two shafts together in the middle of the TA and a carrier without the planetary gears, take out the sprag clutch ( ramp and rollers) and no more TA. It would be straight shafted, as they say.

It would be easy to make your own eliminator with parts you already have in there, but I guess to most people it is worth the $350 for the kit, to not have to mess with it.

Well if you dump the TA, you need the replacement shaft to be hollow. Or the oil flow to the front bearing. The hole is only about 5/16th"s . The oil comes from the pinion gears and flows to the front bearing through that shaft. You will have to do both splits to do this also. At the clutch and the rearend.

You don't say what tractor. If mechanical T/A IH made some without T/A. Several parts were changed though. One shaft can't just be added.
If you could find salvage parts from a non T/A and transmission driven PTO tractor in good shape a straight shaft from clutch to input shaft can be used with a splined coupling joining them. On a T/A tractor the transmission input shaft is part of the T/A unit.
IH made some mechanical non T/A tractors with dry center housings. Oil was only in the transmission housing. Not many non T/A tractors compared to T/A ones though.

I just don't understand why people are so dead set on "eliminating" the TA?!?

It's just as much work to eliminate the TA as it is to fix it.

Once it's fixed, the chances of you EVER having to work on the TA again as long as you live are slim to none. It will probably outlast your children, as long as it isn't abused.

As to cost, if you just replace the ramp and roller part of the TA, which is the problem in 95% of the cases, it's actually CHEAPER than a TA "eliminator kit."

OK now iam getting it. I am wanting to pull the t/a because the tractor is being built as a puller with app 600 hp.

Thanks everyone.

It's really not hard to understand, some people don't want a TA.

It is VERY difficult to understand. Every logical and rational argument comes out in favor or keeping and fixing the TA.

Of course when it comes to tractor pulling, logic and ration are in short supply... You have to admit that 600HP is not terribly logical or rational! Probably the most logical part of that conversation IS eliminating the TA.
