Topic tags/keywords: grizzly 6 jointer cutterhead gib

I have the older G1182 and don’t have the right wrench to remove the bolts for a knife change. The manual is not helpful. Two questions:

What is the size of the gib bolt?
Are they left hand thread?

Don’t know the size, but you can bet it’s metric. I have found it necessary to grind the wrench thinner, as there may not be a lot of room behind the gib. Then it becomes a dedicated wrench. The bolts will not be left hand thread, but you screw the bolt out (counterclockwise) to tighten the gib, clockwise to loosen (screw the bolts in) to loosen the gib.

I agree – I’m betting on metric as every other bolt on this machine is. The set I have is thin enough – just not the right size. I emailed support at Grizzly. Thanks

I have that jointer as well. I had to find a really thin wrench. I happened to have one but if not I would have just ground one thinner.

To close the loop on this thread, here is Grizzly’s reply (I love their support):

The gib bolts are a right hand thread; however, you must tighten the bolt into the gib to loosen the gib. We have not had this version of this machine for many years, but I believe that it should be 12mm. I know that you should have received 2 wrenches with one being 8mm/10mm and the other being 12mm/14mm. If it is not the 12mm, it is more than likely the 10mm. Please note, that if you do not have the original wrenches, the thickness of the wrench could be too much to fit into the slot properly.

Gotta lovem. I am betting on the 10mm or maybe 8mm. Knowing the product line is the first step in having a job in the public. Also a giant step in customer relations. Good luck with your endeavor.

Have your say...
