Topic tags/keywords: question jointer

I have an older Grizzly G1182 6” jointer that I found on craigslist a couple years ago. Up until now I have not had any problems with it. Starting last week it makes a loud clank when I start it up but then it sounds normal once it is reved up. When I try jointing a board the motor looses power and bogs down the cutterhead, it comes to a complete stop after I am 3”-4” into the cut. I am attempting to make a very shallow cut and the blades are somewhat sharp. I suspect that either the motor is bad or the belt is slipping but I am not sure how I can safely find out for sure. What happens when a motor goes bad? Can it loose power like this or does it just completely stop working? How can I test to see if its the belt slipping? Any help or insight anyone can help is appreciated.

It’s easy to check the belt. With the tool unplugged, just squeeze the belt halfway between the motor and the head. It should deflect about an inch.

A third possibility is a slipping sheave. Check those at the same time. Check the set screws for tightness, look for a missing woodruff key.

If indeed the motor is losing power, then check the wiring connections at the switch, the plug and at the motor itself (under a plate or cover of some kind). If those are snug, and if it’s the original motor, it could well be toast. Early Grizzly motors had a less than shiny failure rate.

Fortunately it is quite easy to replace a motor on a jointer.

Belt slap at startup is a known issue with Grizzly jointers. Newer models have a belt tensioner to prevent the problem.

A loose belt might explain the belt slap, as well as apparent loss of power.

I was having a issue with my 8” grizzly which I bought in July it would make noise at start up and I noticed power loss when using. I took the cover off and the belt was fine it was the gear pull had come loose. I tightened down pully and the problem went away. I wounder if your having the same issue I did, I hope that helps.
