Just a short note to say the job to replace the oil seals and bearings on our Dexta is done and all looks OK after a few days work. (4
Hectares slashed, several rolls of hay put out etc)My one addition to the standard oil seal/bearing replacement was to use a "speedie-sleeve" on the axle where the inner oil seals run.
These are stainless steel sleeves designed to press fit onto a shaft and provide anew surface for the seal. (the Speedie sleeve I used is
numbered CR99212 -for the 2.125 inch shaft, approx 1 inch long, it covered the 0.007 inch groove worn by the old seal) If anyone wishes to buy bearings, the cone (The bit that goes on the shaft with the rollers in it) is numbered 387 and the cup (the outer bit
that goes in the hub) is 382. These are recognised by the bearing companies and the parts are sold separately. In Aus the retaining rings were readily available at $Aus80 each, as were the inner oil seals. The outer seals, like the bearings are
standard items that could be brought from a bearing shop! Getting the bearing off the axle (after removing the ring using a 3/8" hole drilled all the way through ... carefully avoiding the shaft)
required more push than I had. A friend of a friend helped out with a 30ton press that made short work of the obstruction to progress
(about 10 ton was needed to shift the cone on one side, the other about a ton). Appropriate amounts of heat as suggested by Limpan earlier in this thread made reassembly a treat. I did have to remove 1 x 0.020" shim to get the axle freeplay to within the 0.004-0.012" tolerance specified ... hope that was just wear
rather than me making a blue! Thank you all for your help with information to allow the job to proceed. regards David
