A substitute for the 2282-25, LEFT SIDE, is BCA-208FF or MRC208SZZ or SNR6208EE. For the smaller RIGHT SIDE 2280-15. use BCA 304 or equivalent. Toss out the unreliable copper disc seals and leave the bearings sealed with seals as fitted.....Joe

it was just what I was looking fore.But there is only one thing of which I am in doubt about, instead of roller bearing
the other you write about is ball bearings.would main drive gear squirm and lie in a greater pressure on

Mickael: I am not sure what you mean by the main drive gear squirming. Actaully, the ball race runs in its own track so the side thrust is bassically within the ball race unlike a roller bearing which needs thrust washers to control its position. as for the shift rod, its indepenent of the main drive gear but I am not sure what rod you are reffering to as there is the clutch pull rod and also the fork shifter guide shaft or rod. Please clarify what your concerns might be using ball bearings. People have used em for years iJD Tranies ncluding myself also on JD trannies.
harbor vintage put sealed bearings in mine .they needed the case, the large nut that holds the main shaft in and the shaft for the slider gear .i know they machined a few things. i just don't know what things

Fellas, If You go with the bearing numbers I posted earlier in this thread, NO MACHINEING IS REQUIRED, That is on 1925 to 29 including and VL trannys beyond 1930. BUT, 1924 and earlier transmissions are done up several differnt ways as the bearing is narrower on the sprocket side..1924 and earlier Right side bearing is same as 25 and on to the 1030's.....Joe

what I mean,was that I thought mayby the output shaft would twisting,and put a bigger pressure on the mainshaft..
just some thoughts I had about it.
now when we use ballbearing..?:)
