A small problem always pops up when i hit the road sawing. The blade tensioner on my lt40 gave out during a blade change yesterday. I have the parts located and will be picking them up this morning. Is there any difficulty in this rebuild?

 We just rebuilt ours yesterday. The only problem was those "too small" allen head screws. We could only get one out. I took the unit to a machinist to have the others removed. If you run into the same problem you may be able to loosen them by tapping with a small chisel. It was quicker for me to drop it off and have it done. I'll replace the screws with cap heads later. As for now,I coated the screws with "anti-seize".

That was a very simple rebuild.  I didn't have anyone there to take any pictures, and my hands were too oily to fool with the camera.  Refilling the reservoir with ATF took the most time.

I only rebuilt half of mine, the tightening side.  The entire unit would have to be removed to replace the bandwheel side and mine wasn't leaking, so I let it be.  The kit has the seals for both sides.

Here is a picture of a failed rubber seal.  It had actually extruded between the piston and the cylinder wall.

This is my refill bottle with a tube spout.



I don't actually remove the threaded tensioner, just screw it all of the way out.

My blade tensioner failure actually prompted my Comfort Zone thread.  It happen the week before I was scheduled to travel that 160 miles one way.  If it had waited a week later, that $15 break down would have cost me big time.

Awe, I'm actually ashamed that I questioned this task. I think the phrase "So easy a caveman can do it" applies here. ::)


And.... Thanks guys!

Mine needs to have this done, where are you guys finding the bottle with the long flexible tube at?

When I had a LT40 I would just use the spray bottle that I used to lube the rail and chain. You will miss the small hole a bit but not enough to worry about.

Many parts stores have a display of the oilers at the checkout.  I'll look and see if I may happen to have an (almost) empty one.

Thanks for the offer MM but I don't want to impose on you. I'll have Patty look when she's there on Monday getting a battery for the 4 wheeler.

Norm;
I just use a common plastic pepsi bottle.

I located some clear plastic tubing similar in size (1/8 inch or so) to the tubing on a bike or 4-wheeler battery vent!

I drilled a hole, slightly smaller than the tubing in the middle of the pepsi bottle cap and squeezed the end of the tubing and pushed it through the hole in the cap.

Once inside about ΒΌ inch I just flexed it a little and it expanded outward against the drilled hole.

Works great!

Thanks Chuck appreciate the help.  :)

I use a large plastic syringe without the needle and a small piece of tubing on the end. Had some on hand that I use on the llamas and horses. Worked great for me.

   Norm, check Patty's sewing room (if she has one). Sewing machine oil also comes in those
little bottles with the pull out flex spout.

Yup, We have a Kenmore bottle that is well over 40 years old that came with Pat's first sewing machine.



That little spout telescopes out of the bottle 8" and all of the way back in for storage.

Hmmm Patty does quite a bit of sewing but I'm not allowed to play with her toys. Something about go break your own stuff.  :D

Thanks again for all of the help guys.
