Re: Blade tracking problem


 

¿ªÔÆÌåÓý

??? ??? I would pull the blade & check each wheel for deflection both in & out & side to side . Have you ever checked the oil level in your gear box ? I checked mine he day I brought it home used . I could see that it was one of the newer saws with very little wear visible till I got the blade cover off & the gear box cover off . I bought mine with a bad motor , but I got it real cheap . I could see where the blade had been scraping the inside cover at both the top & bottom . That was the easy fix , I think I replaced one bearing & adjusted . But before I could adjust the wheels I had to address the gearbox issue . Mine was bone dry . There were 3 seals on one of the shafts all of which were installed wrong , I replaced 2 seals & maybe a bearing . Fortunately I caught mine before it had caused a lot of damage to the brass gear inside the gear box . The dry gear box on these saws is more common then you would think .

Make sure your wheels are both turning true & flat . I see that the parts list for these saws?? ( the ones they currently sell ) shows 2 seals but I could only find one in the parts list . I was able to get the #'s off the bad ones & went to my bearing house & got some good quality seals . I think there's only 2 different bearings in these saws , I went on Amazon & got a ten pack of each for @ $20 .

The other day I was cutting some stock with my HF bandsaw when I noticed a new scraping sound coming from the area of the bottom (drive) wheel.? Further examination showed that the blade was riding far enough out that it was scraping the inside of the blade cover.? Thinking that I just needed to adjust the tracking (something I haven't done since buying the saw), I started in on that -- but quickly discovered that the blade was riding properly on the upper wheel.? Not quite touching the flange.

Some additional experimentation showed that the drive wheel tracking problem is eased when I reduce the blade tension a bit.? I don't think I'm overtightening the blade and bending the frame -- I'd think the upper wheel would be more affected (but I could be wrong about that).

I'm not hearing any noise from the drive shaft bearings so think it's unlikely they have worn enough to cause these symptoms.? Maybe I just noticed something that is common to these lightweight machines?? On the other hand, if the problem is flexing in the drive shaft, that could be a recipe for metal fatigue and eventual failure.

Comments?? Has anyone else observed this?
