I've dismantled my 1275 Midget box ready for renewal of bearings and baulk rings. I'm stuck, though, or rather the large bearing at the rear of the third motion shaft is. Is there a way to remove it without a hydraulic press or puller? Not keen to cut or break it, in view of the potential for damage to the shaft.
I just bashed mine off, ie drifted it rearwards, it doesn't matter as you're replacing it with new bearing anyway. When installing a new one, heat the bearing in the oven for a short time and it will just drop on with no need to do any brutality to the new bearing ! I'm literally just doing all this malarkey myself this evening !
I'm sure whether you are talking about removing it from the gearbox or from the shat itself. In either case the speedo drive pinion clamping nut can be used after making the appropriate adapter to either bear on the casing or to grab the bearing.
I think my main problem was that I didn't understand that the diagrams and instructions for the 1098 box don't translate directly to the 1275 box. On the 1275 you can't get a hammer to the bearing as first and second gears can't be removed until after the bearing, as the shaft has a permanent flange between second and third. In the end I cut the bearing with a Dremel and chisel with no damage to the shaft. Spent most of the afternoon removing the retaining ring behind third - on the 1275 this has not one, but two springs and plungers! Still trying to work out how to put this back together......
Like the sound of using the case and speedo drive nut as an extractor, but I'd cut it before I saw this.
Thanks both, and good luck with yours Lurch. We know how to have fun, don't we?
