Greenlee 1346 bandsaw gearbox

[alfadan]

I purchased a Greenlee 1346 bandsaw a while back. I dropped the saw backwards and bent the input shaft. I tore it down and straightened the shaft and replaced the two oil seals.
There is virtually no information on the innards of this gearbox so I thought I'd put some pictures and bearing/seal info for anybody in the future.
The input shaft is .625 with a 3/16 key.
Input seal: SKF 7661 (inner seal lip is very tight and needs worked around the seal face, chamfer the front of the sealing surface if you can)
Output shaft: .875 with 3/16 woodruff key.
Output shaft seal: Timkin 471646
The input shaft with worm gear rides in two tapered bearings. It is retained in the housing with an internal circlip under the input shaft seal.
Input bearings: Timkin M12649 (qty.2)
Output bearings: Timkin LM119 49 (qty. 2)
Housing gasket .025 thick.

The manual says to use 10w-40 motor oil. I used 15w40 diesel oil.

The Greenlee 346 may use the same gearbox.
Hope this helps someone.

alfadan - A hearty and belated thanks! My 1346 gearbox started leaking and I just pulled it to try and figure it out. Your info makes that process a lot easier.

Was trying to cut some 1" angle miters to make some frames for a project - and I just could not get the angles to be consistent...
Turns out...
1. The drive wheel was missing about 20% of the tire...
2. (The remains of) both tires were severely cracked and hard as a rock...
3. The non-drive wheel bronze bushings, as well as the associated steel shaft attached to the tensioner were also well worn...
4. Both the fixed and moving clamps were out about 40 thousandths from mating "flat"...
5. 5 of the 6 blade alignment bearing races were way looser than they should have been...

I bought this via Craigslist maybe 5 years ago, and have just been using it for various non-critical stuff. Time for a little love, I guess.
Spent about $100 in parts, and all should be well soon.

Some questions:
Did you make your housing gasket of paper? Or ???
Have you figured out a means to attach a hydraulic cylinder for downfeed control?

Of the probably(?) thousands of these sold in the (I assume) 70's and 80's, not many folks posting any questions/comments/concerns/upgrades.

Best.
