oldiron user Posted January 28 Share Posted January 28 Oil holes disappeared. The lube hole is still there, but apparently when remanufacturing these the seal ring area is renewed by machining off the area and replacing with a sleeve with new ring grooves. And when the sleeve decides to rotate on the shaft there goes the oil holes and TA no longer works. It ran for maybe 25 hours before doing this. Anybody no any more about the rebuilding process? 1 Quote Link to comment Share on other sites More sharing options...
ksfarmdude Posted January 28 Share Posted January 28 Wow that's sux Where did you get your parts from ? Quote Link to comment Share on other sites More sharing options...
Matt Kirsch Posted January 28 Share Posted January 28 Frankly expect to see more of this in the future. You can't keep rebuilding the same cores over and over and over and over and not run into situations where the wear in some area is just too great. The options are machine a whole new part, or try and patch it with a band-aid. Guess which one costs less. Quote Link to comment Share on other sites More sharing options...
Ed Leaman Posted January 28 Share Posted January 28 You are correct in the process used by some of the re builders, Machined and a thin sleeve pressed on. Never saw that happen without the center part of the shaft (inside the sleeve) taking a twist and only remember two twisted in the ring area in my time of being around Ta's. This one appears to have been improperly fitted and it probably turned when scrubbed against the bushing wall. Wonder what the bushing that it rides in shows for clues? In defense of the re-builder's, the reusable cores for 13 spline (larger shafts) have gotten real hard to find. And Matt is correct in the cost assessment, But I would say that there are lots of TA Shafts out there wearing that fix with out causing any troubles, it has been used for a few years now, and most have been successful. There are a few places building new shafts but they are spendy! ed Are they iron sealing rings ? 1 Quote Link to comment Share on other sites More sharing options...
oldiron user Posted January 28 Author Share Posted January 28 Thanks Ed, I was hoping you would see this. Yes, I guess you would call them iron rings. Bushing isn't bad, but probably a little more marked than it should be for such low hours. I know you can't tell a whole lot from the picture.

NCIH1466 Posted January 28 Share Posted January 28 Ed rocks! Just had to say it....top notch TA people! 1 Quote Link to comment Share on other sites More sharing options...
Ed Leaman Posted February 1 Share Posted February 1 The bushing we need to see is the one in the "red" cast housing that actually surrounds those cast rings. it will have 2 circles of holes that direct oil to the clutch pacs by forcing it between those rings. in to the shaft and endways through the shaft to the clutch pacs.

oldiron user Posted February 6 Author Share Posted February 6 Oh, I should have known which bushing. And responded sooner. TA came from A & I, and guess what, they aren't interested in the deal because they don't have a warranty card on fie for this T.A. We are thinking about staking the holes to the inner shaft (to prevent more turning) and reopening the holes in the sleeve in the right place. Crazy or not?

ole 815 Posted February 6 Share Posted February 6 So they need warranty card prolly, because that is a Hi- Capacity TA. A&I needs to cover their end, why no card? If only 25 hours? 5 year warranty if I remember correctly. Quote Link to comment Share on other sites More sharing options...
ksfarmdude Posted February 6 Share Posted February 6 Nothing worse than getting inferrior parts , Last T/A I installed was a mechanical diode version from Case-IH it also had a 5 yr warranty with out stupid warranty cards to send back I never had any problems with it Quote Link to comment Share on other sites More sharing options...

I would just find a shaft and put it in there, If you need help locating one pm me or find my cell number or try (888-Lea-mans) Can you post a picture of the sprag? I assume its the one with the big brass bushing used to keep things straight? On this picture here whats the reason for the rust around the bushing?

oldiron user Posted February 8 Author Share Posted February 8 As for the rust, guess A&I or Hy Capacity would have to answer that. And I will contact you concerning a new shaft. Thanks Quote Link to comment Share on other sites More sharing options...
Ed Leaman Posted February 9 Share Posted February 9 Is definitely a Hy cap TA, I was looking for the sprag to be like BMD sold. But that sprag is what HYCap sells. Quote Link to comment Share on other sites More sharing options...

Ed, I'm thinking 2015 or before was the last year, of the BMD/A&I style TA. I know in 2016 A&I was for sure sourcing them from Hi-Capacity. BMD & Allied both used a sleeved input shaft also if needed. Mark Quote Link to comment Share on other sites More sharing options...
Ed Leaman Posted February 11 Share Posted February 11 I liked the BMD style sprag better (was actually a Dana product and promoted through Aer-Vac) than anything built until the wider Renoud came out in the late 80's And I still have some of them running in places where nothing else would have stayed.

Ed Leaman Posted February 13 Share Posted February 13 I never learned who Mr. Boykin had doing his work but we sold a ton of his sprag kits in our ta's back in the 70's, and 80's Quote Link to comment Share on other sites More sharing options...
