Topic tags/keywords: jointer motor

Hi,
got a problem seems like. I’ve tried to include a sample motor to go by. What the problem is the belt is staying on, but the round cylinder keeps sliding off of the metal rod that is attached to the motor. There is a small square like pin that goes inside a groove and you tighten a set screw down on it. Problem is after my shop vac gets tired of picking up the dust the jointer will start to blow chips from the blade. At this point is where I usually clean it out again, but if I let it go the knives will stop and the little block has come loose and the round cylinder isn’t snug against the motor anymore.

Any ideas, i’ve tighten the block pretty good I thought.

Thanks,

Kevin

It needs to be tighter. If it is an Allen set screw, you need a longer Allen wrench to snug it up.

If the pulley is aluminum, and it has run sloppy, the hole in the pulley may be galled (worn and distorted) so the pulley won’t seat squarely on the shaft, and even if the set screw is snugged down it will loosen itself pretty easily.

Loosen the set screw and, with the key stock (square piece of metal) in place, can you wobble the pulley? You can often tell by looking at the pulley if it is galled.

A really smooth running jointer often got that way by getting quality pulleys and a segmented belt.

Kindly,

Lee

Thanks Lee,

I’ll take a look tomorrow when I get home. I’m thinking it may just need to be tighter. Once I get the pulley on the rod it doesn’t move at all.

Well Lee, it looks like I just overlooked something small perhaps. There is a set screw that holds the small rectangle piece and there is also another set screw that I didn’t see. I tightened that one down and let it run for a few minutes. So far it’s not slipping.

Hopefully that was all it was.

Thanks,

Kevin,

This is a very common problem. The set screws that hold the key on a pulley will generally vibrate loose unless you apply a product called “Loctite” to the screw threads. It comes in different grades for different applications. The blue thread seal is all you need. Its about $5 for a little bottle, but a little goes a long way.

Mcase,
Thanks for that tidbit of info. I’ll get some and slap some on it :)
