Topic tags/keywords: grizzly g0771z trunnion issues

First time post. i wanted to show the issues I’m having with my new saw. The trunnion does not track up and down properly. I have checked most of the stuff i can think of. I also have already sent an email off to Grizzly and i will see what response I get from them.

I was hoping someone could maybe chime in on a fix, or this is a common issue with this saw. i read others that had close to the same issues with other saws. all seem to just return the saws. i really dont want to go through that. i do like the size. the fence seems to be keeping adjustment etc…. but the most important thing to me is whats not working correct.

thanks ahead of time.

the video i made of the issue is here : https://youtu.be/ZvpvVYdhgJo

Sorry to hear you’re having issues with it. I just got one of these and mine doesn’t seem to have this problem. I’m interested in hearing what they say about. Hopefully they can come up with some type of solution so you don’t have to deal with sending it back.

thanks for the reply!, glad to hear that yours does not do that! may just be an isolated problem.

I am only guessing right now. i think that the pivot hole in the arm is machined crooked/ out of square, if the pin was bent it should still move strait up and down, unless the pin is spinning with the arm.

im waiting on Grizzly to let me know what they want to do, i sent them a link to the video too.

ok, here is an update. talked to Grizzly. I originally decided to just return the saw and upgrade to the G01023RL. but there are none of them in stock, they would not have any until April. They are also out of stock for a replacement of the G0771Z (not sure when they would be in). So i decided to try to figure out what is causing the issue and just get parts sent to me. its down to 2 parts. the one is the arm for the arbor(part #38), the other is the part that has the pin the arm pivots on(Part #70). without the motor, riving knife, etc. the arm still does not move up and down straight up and down.

I am going to mount the arm to the table of my mini mill and see if the bore is out of square to the faces. i will try to post pictures or links to video when I’m done.

Attached is a response I got from Grizzly today:

“We appreciate your interest in our products. The G0490 Jointer is currently out of stock on backorder and is expected to arrive in our warehouse on approximately March 30, 2018. Also backordered is the G0771Z Table Saw, which is expected approximately April 13, 2018. Once received, backorders are processed and shipped to arrive in approximately three to five business days. We do fill backorders first, and shipping and handling charges are prorated and charged as the items are shipped from our warehouse. We apologize for the delay and any inconvenience this may cause.”

I am having serious second thoughts about buying from Grizzly. They are having factory issues in China and it seems their quality control is not up to par right now. Many people who have actually gotten orders recently have had QC issues it seems.

Hopefully you get some resolution soon.

im not saying there is or is not an issue with QC. what i do know is that when you do contact grizzly you do get to talk to a person. i know for myself that the fact that i just bought a $1000 saw and there is problems, this should not happen. i also know i have bought new TV’s and they dont work out of the box either. i would still buy from grizzly, the price for what you get you cannot beat. being able to talk to someone that is willing to fix the issues, thats hard to find. I know i will be very happy with this saw soon as the problem is resolved.

dont give up on them yet.

Some hesitation is understandable, but keep in mind just how many machines that Grizzly sells overall. I suspect Grizzly sales may be as much as most of their competitors combined. Most people buy without issue, and just use their machines successfully. Those with issues are far more likely to post about it on the internet. Reading a few complaints about Grizzly doesn’t necessarily mean they produce more defects than their competitors, but due to the sheer number of units sold, it’s logical to read about higher numbers of problems. It’s been a while since I bought any new equipment, but it still appears that Grizzly is a reputable company who stands behind their machines, and offers a great value in most of their machinery.

Not trying to sway you one way or the other, but did want to point out the bigger picture.

I checked my alignment again after I had some burning and I actually do think I have a similar issue! I don’t think I was checking carefully enough before. I didn’t have a dial indicator at the time, so it was difficult to get a more accurate measurement, but ordered one and have one on the way. I have a call in to tech support and am waiting to hear back. Let me know if you make any progress. Hopefully there’s a fix that doesn’t involve too much disassembly. .

CCC118, sorry to hear you are having the same issue. the part that is most of the problem is part #38. i was sent one and it made the problem a lot better, it is not perfect though. the largest issue is the design of the lift itself. if the bore in part #38 is off just a little from the face it will cause major issues at the farthest point away from the pivot point.

replacing it is very easy. you should not have any issues with it. you will just need some tools. snap ring pliers, some metric sockets.

I am running my saw now and its doing a lot better than it was. if yours is moving good and then it goes way off when it is lower, there may be some casting flashing that is hitting causing the arm to flex. i did fine mine had that issue on top of the part just being machined wrong.

Tony, thanks for letting me know. I’m glad you got it working better. How far off would you say changing the blade height is throwing off the alignment after changing the part now? I need to decide if changing that part will make it close enough to be acceptable or if I’m better off just sending it back, which would be a huge hassle.

the saw is within .007-.010 i personally would like it better, but it really is close enough for what i think i will be doing. before the part change it was off almost a 1/16. its way better than it ever was.

when i changed the part. these are the steps i took. unplugged saw first thing.
1. removed the covers.
2. remove the blade
3. remove the riving knife arm by removing the snap ring behind the arbor
4. loosen the belt adjust bolt, removed the belt.
5. remove the motor by removing the pivot nut and the adjustment bolt. i just set the motor on a little stool and did not remove any wireing.
6. remove the part #38
7. remove the arbor
8. remove the bearings, you can tap them out with a small peice of wood, brass punch, the bearings have just a snug fit. not a lot of press on them.
9. reverse the procedure to put back together.
10.then you have to align the table to blade again.

i dont think i missed any steps, if i did sorry. was writing this from my head.

Thanks Tony, I’ll talk to tech support again on Monday and see if they can send me that part.

After a week of going back in forth with tech support, they’ve finally agreed to send me the part, however it’s backordered and they need to source it. They said that it might take an extra day or so. Hopefully they’re right, as I’m starting to run out of patience. I’ve had the saw for about a month and still don’t have it fully up and running. I detailed this on another forum, but they miss-drilled my extension wing holes when I first got it so I couldn’t even fully assemble it for a while until that was corrected. They were not drilled in a straight line and wouldn’t line up with the table and needed to be elongated. I’m hoping I can get this sorted out soon.

Have your say...
