I’ve recently purchased a 10-speed 1978 Meddings MF4 Mk3 pillar drill which has high range and low range Tufnol gears - the high range gear is stripped and needs replacing. I mainly do woodworking, so this kind of maintenance is a learning curve for me.
Having started to disassemble the gearbox I was hoping to obtain some advice on removing the bearings from both the input and output shafts (15mm and 25mm diameters, respectively) as some of these need replacing (damage and play between inner race and rest of bearing) and at least one needs to be removed to allow replacement of the gear anyway..
From what I’ve seen bearings should be removed with the force applied to the inner race (I had previously thought of using some 3-legged gear pullers to try and get them off). There are budget sets of bearing pullers available online and it’s stated these are 2” or 3”, for automotive use, which are obviously larger than the shaft sizes on this machine. I’ve not seen any smaller sized tools available and wondered if anyone could suggest a way these bearings might be removed.
I’d be very grateful for any information or advice anyone might have
