Topic tags/keywords: question porter cable tablesaw cant get the height adjustment to work on my table saw hoping someone has gone down this path before

My first time asking a “forum question” so here goes: I purchased the above model table saw from Lowes about two years ago…Other than being really HEAVY (compared to the 10 in Sears Table saw I was replacing after 25 years of faithful service) it assembled just like the instructions called for and after buying a “better blade” went into immediate use…I have built numerous projects and have never had a problem until this afternoon…When I tried to raise my blade after cutting some 1/2 inch dados in some 2×4’s the adjustment wheel just spun (without raising the blade)... After unplugging, I flipped the saw over on it’s side to get acess to the bottom…It LOOKED like the shaft had simply come loose. Two small allen screws which hold one of the two 45 degee bevel gears together…Took a while to figure out how to re-attach….BUT, after I got the gear back on the shaft and the teeth meshed the blade still won’t raise or lower?There has to be some little tiny detail I’m missing Has anyone had a similar problem with this “otherwise” OUTSTANDING saw….well, until today…

Is the wheel spinning on the shaft or is the shaft spinning? Could be a broken rollpin in the handwheel.

First off: Howie I “DID NOT” attempt to flag your response…just have never done a Forum question and wasn’t sure what the flag button was…so if anything is sent to you regarding that subject PLEASE let me know as there is NO ISSUE with anything…OK

When I pulled out the short shaft, it consisted of the hand wheel (held on with an acorn nut) a small sleeve, spring, and the blade locking handle…inside, there’s only the bevel gear (held in place by two allen screws) and two, I guess alignment washers…they seem to take up a tiny bit of movementto further keep the gears meshed together under a little pressure. The plastic handwheel fits over a “key” (actually, a flat – when you look at the end view of the shaft it’s like a “D” the handle fits tight, in other words…Once I got the gear put back on…the whole assembly “seemed” to turn correctly…you could rotate the other “gear shaft” and it, in turn, would rotate the other one (including the handle) It’s just this motion does NOT raise and lower the blade assembly and motor…THAT assembly will slide (freely) up and down on two “other” steel shafts, but not as a result of cranking the adjustment wheel, itself…I’ll look in my manual for this roll pin, but I didn’t see anything that looked to have “broken off” the shaft and I didn’t find any broken pieces when I cleaned out underneath the saw, before trying to “see what was wrong”...

Thanks again and I’ll let ya know if/when I get a solution…

Thanks for reply…I’m going to give the Porter Cable guys a “try” today…I was just hoping yesterday, since I was right in the middle of working on my project I’d get LUCKY!! It being Saint Pat’s Day! Problem is, one year warranty has run it’s course (no big deal – I’ve always had pretty good luck with my power tools – my Dad taught me the value of proper maintenance and safe operation)...Also, it goes without saying sometimes you get someone, at a company, who really really knows their stuff…and then there’s the “other” possibility? But I do plan to try them as well…I will make sure, since I’ve asked for the “assist” , to post the solution – soon as I find out WHAT THAT IS!!

I am having the exact same issue. Could you share what the fix was?
