Quick help please......LT40 Blade Drive Wheel Alignment
« on: March 01, 2012, 09:10:31 PM »
I am doing a complete alignment on my LT40.  I have taken the guide roller assemblies off and started to check the blade wheels for alignment.  The Drive side is a 1/4" off by checking it with the blade guide alignment tool.  The business end of the blade is higher than the back of the blade.  The manual says to adjust the vertical adjustment screws.  I loosened the bottom screw and tightened the top to tilt the wheel down but no matter how much I loosen the bottom adjustment screw and tighten the top one, the wheel wont move. 

I am about to pull my hair out.

I don't know what the problem was but I tried to adjust the wheel up and when I did that it freed up.  I was then able to adjust the wheel down and get it to within a 1/32 of an inch.

I've just started the alignment and blade guide replacement job on my mill, just take your time and go step-by-step.

Yes.  That seemed to help also.  I don't know why but it wouldn't tilt the wheel down until I tilted it up and then back down.  Strange but it worked.

A can of penetrating oil will help to free it up. Disassembling, and wire brushing the parts, then applying a light coat of oil will go a long way to make sure that you are accurate and that no wood fibers are holding it in place, as they will shift leaving you pulling your hair out again in just a short time.
Just get out the book and go thru it step by step and a good alignment will hold for quite a long time.
