    I am only going off what I have read on here, I haven't dealt with them myself.

    Default A slight problem

    Got the new blade and pulled the idler pulley off to check the ball race (sic).

    A bronze bush greeted me, and a very worn one at that. And the shaft has noticable wear as well.

    Gearbox end is all OK.

    So there's a few options on how I repair this.

    Such is life.

    The worst that can happen is you will fail.
    But at least you tried.

    I can't remember that post, have you got a link to it ?

    I gave up working in the shed today when it got to 41C at lunch time, damn hot here.

    I've machined a bronze bush to fit the pulley centre (Dufor spring shackle bush).

    This has a much larger centre diameter than the original. I will then make up a sort of very thick Speedie seal to press onto the worn shaft. This will give it a larger rubbing /load bearing area.

    Bronze is damn hard stuff, so this saw has done some serious work at some time. The pinion gear in the GB looks like new, so maybe that's been replaced.

    I pondered over fitting ball races but went this way for now to avoid issues and get the job done.

    The pulleys on these saws only turn relatively slowly, so the lube should last a long time.

    That's about it for now.

    Cheers

    Congrats on the saw. If you plan on doing a lot of 45 and 90 degree cuts this might help. I made up a triangle out of 50X6 FMS set at 45 deg. with a hook on it to catch on the fixed plate, it was made a bit longer as well so that the blade trimmed it to length as a marking/lineup point. Makes life a lot easier, not having to reset it after every other cut.

    looks like you have it nailed rob i just had a look at mine fortunately its not worn and i checked out the parts list looks like remove spring pin 105 remove shaft 107 and replace bearings and shaft as neccessary in your case no need for the parts list
    the spacer behind the wheel is very basic i must say

    I have the same saw is a great little saw much better than the new model

    I had to replace the bronze gear in the gear box and make a new drive shaft, I also made a stand wit coolant pump from an old bed and a pond pump

    IIRC the bush in the gearbox only wears on 1 side and I cheated and turned it around.

    Rob to spur you along this is realy pushing its limits but i cut off a piece from a 5 inch piece i got from a scrap metal place
    had to turn it near the end but it worked mine doesnt cut all that square but much easier than a hand saw

    BASIC, that's the understatement of the year - it's just a small loose collar cut out of some thin walled tubing. LOL.

    I'm going to ditch that, and machine a flange on the inner end of the Speedie seal, and that will rub against a similar flange machined onto the Dufor bush in the pulley. This should be a way better arrangement.

    Thanks for all the tips and links guys, I will go through them all.

    I see on the JET model much like mine, they have an adjustable support bracket from the back of motor mount plate down to the rear of the swing arm section.

    Anyone got that on theirs??

    Cheers

    Why is the bronze gear worn near the edges and not in the centre?

    Looks like the mesh point is not correct.

    That's an oops. I meant bush but my memory may be wrong. Input shaft? Something else all together?
