Topic tags/keywords: jointer grizzly g0604 pulley spiral shelix

So I’ve had my Grizzly G0604X (6” jointer) for a year or two now and it’s been great. After a bonehead move by me while planing some reclaimed pallet wood, all 4 blades were pretty well shot and with Grizzly offering a discount on the Byrd Shelix cutterheads right now, I decided to treat myself to a little upgrade…

Well, here is where my dilemma kicks in: For the LIFE of me, I can’t figure out how to get the pulley off the cutter head drive shaft… every post I read just glosses over this aspect like it’s a cakewalk but my pulley just will not budge.

I’ve removed the bolt & washer that secure the pulley to the shaft. There’s no set screws holding it. I’ve tried a pulley puller but that just ended up snapping a chunk of the inner edge of the pulley off (I’ve already received a replacement from Grizzly).

The parts diagram shows a couple retaining rings (Part #67) but I haven’t found how to access/remove them (I don’t even know that they’re pertinent to this situation)

Can anyone offer any help? I’m as stuck as my pulley is.

You may not be able to just wrench it off. Tighten the puller then tap the center bolt shaft of the puller with a hammer, then tighten the puller slightly more and continue to tap the center shaft with a hammer gradually pulling the pulley off.

The easy solution is to just buy new bearings. I did a review on the same cutterhead and the covered using a pully/gear puller in the review- but not in depth.

I had a hard time getting the puller claws around the outside of the bearings due to limited clearance between that and the blades. It did work, but it wasnt easy and it was a struggle in patients to get all three claws seated with the puller “bolt” centered on the cutterhead shaft. Once all three claws are set and the puller is tight the “breaking” force is immense, but once overcome, its pretty easy. I struggled getting both pulleys started but once the puller is “set” its just muscle. (if you haven’t already- take the blades out of the old head. )

edit: thinking about it- i’m pretty sure i got two of the three claws tight, and kinda forced the third in by taking a small fraction of a turn out of the bolt but keeping the two claws seated, taught almost like snapping it place by effectively tightening the two set claws by trying to raise them (pushing the bolt from the top in the direction of the free claw) to get the third in place and at the same time loosening the bolt ever so slightly to allow the third to snap in.

PS: I’ll add I was very very close to just ordering new bearings- but kept fighting it for a few more min and got it and the second was much easier – after having a better idea that it’s actually possible.

Well, if the existing pulley is already broken, and you have a replacement, you don’t need to be too gentle. Worst case, cut or grind it so you can get a good bite with the puller. Or just cut or grind the pulley off. Or cut the shaft itself. Have you considered trying a torch to heat up the pulley; might help it loosen up.

I just went through a head change-out with a G0490W (8”). I had no problem getting the pulley off, but found the retaining clips impossible to remove. The head made it impossible to get to the holes in the clip. I had a mechanic friend try every snap ring pliers he had and none would work. We ended up beating the shaft loose from the bearing with a sledge. Once the bearing was loose, and I could slide it down the shaft a bit, I could get the retaining clip off. Since the end of the shaft had mushroomed removing the bearing wasn’t worth the trouble. I would strongly recommend having a spare set of bearings on hand; they are inexpensive, it’s a good idea to change them anyway, especially if you have some mileage on the old ones.

I thought it was funny that the youtube video Grizzly has showing the process for changing the head doesn’t even mention a retaining ring. When I contacted customer service they had no suggestions at all.

Good luck. The spiral head is great once you get it running. It is worth the effort.
