Help! - Input Shaft Main Bearing Question

(long post, sorry!)

I rebuilt my sammi tranny yesterday. Used the step-by-step writeup at Izook.com, and got through the entire rebuild in just under 5 hours. I am not a mechanic, I've never looked at a tranny before. I did have use of my brother's tools and shop space - and his guidance and a little help to remove and seat a couple bearings.

Things were going really, really well. Every time we took a bearing off, we matched it to the bearing number in the new rebuild kit, as well as to the physical specs. We had everything done on the countershaft AND the mainshaft, when we ran into some trouble. After we removed the *last* bearing from the front input shaft, we opened up the remaining bearing box, and found that the only bearing we had left was NOT a sealed unit bearing. The bearing that was originally on the input shaft WAS a sealed bearing. We double, triple and quadruple checked each and every bearing we had on there, and looked at the boxes (which we kept), and there is no way we mismatched anything. The kit DID NOT include any sealed bearings! I had little choice at this point in time, since I couldn't leave the tranny at his shop and since the reason why I was rebuiding the tranny is that the bearings were shot. I didn't want to put the old bearing back in there, so we went ahead and put the 'open' bearing on the shaft (same bearing number, only the suffix was different), and put the case back together.

Needless to say, I need to know ASAP if that open bearing in the front of the input shaft is okay to run. It looks like it will get lubed the same as the rest of the bearings, and there are some passages that will get the gear oil up to the bearing. But it is in the very front of the case. My gut says there was a sealed bearing on there for a reason.

I'd like to hear from some of the tranny experts before I put that tranny back in. If there is no way I should run that open bearing, I'll bite the bullet and open the case back up (ugh) and put a sealed bearing on there. I'd also like to hear from you guys before I contact the vendor that sold me the rebuild kit, so I'll have my facts straight and my act together before I call them and let them know how disappointed I am in their 'kit'.

Needless to say, I am not a happy camper right now, and all advice is greatly appreciated!

(vendor name withheld pending outcome of my issues)

Re: Help! - Input Shaft Main Bearing Question

Spacedude,

I recently purchased a rebuild kit from Trail Tough and have not installed it yet. Reply to this with the bearing number in question and I will check mine to see if it is sealed or not. Depending upon who you bought the kit from, it might tell you if the open bearing was a mistake or not.

Re: Help! - Input Shaft Main Bearing Question

Brad - thanks for the reply. Here is what I got with the kit:

1 - input shaft to mainshaft needle bearing

1 - 6228NR (End of counter shaft bearings - with circlip retainer. Pretty wobbly.)

1 - 62/28

1 - 6304N


1 - 6206N (IIRC, this was the center bearing in the mainshaft. It was toasted)

1 - 6305N

1 - 63/28N (this is what I put in the front. The bearing that came out was a 63/28 LU)

Re: Help! - Input Shaft Main Bearing Question

Most rebuilders put an open bearing in the front so it can get oil to it instead of using the sealed one .

Sarge -

Thanks for the reply! It was just very frustrating to get to the last bearing and not have it match. It was even more frustrating since the kit had absolutely NO install notes included with it to explain the potential differences in the bearings.

I guess if I was a professional, then I'd expect that. But as a hobbyest, I would think that the Vendor would have at least included a few notes, etc.

Re: Help! - Input Shaft Main Bearing Question

No problem . I know myself I need to include some better instructions with my own products , I'm just as guilty of that . Sometimes some of the things we take for granted are not realized by the customer , it just makes for headaches .
