Help with a Rapidor Power Hacksaw

what are you cutting? check the brushes first. and the bearings. might just need a tune up.

Thanks The machine will be used to cut mild steel up to say 3" diameter I think the problem lies with the bearings, but as I have nothing to loose I will strip the motor down and check.

those are easy to repack or replace.

motor stripped and bearings repacked. The rear of the armature is a sloppy fit in the bearing and may be turning in rather than with the bearing. The front is little better and the bearing O.D. is a sloppy fit in the front housing.

can you shim and center line the drive? also check and see if the armature is out of round. i've had egg shaped ones that made the shaft wobble. great for special effects.

Thanks

Many thanks

bearings replaced with lots of bearing retainer to take up the slack. Motor runs well and sounds good. Job done.

excellent. if maintained, motors can lost a long time. the brushless ones should be good for years of non stop labor. good job.
