TSA001 bearings

[Chrism3]

My TSA just started making a very rough noise, and when I turn it off there is something still slowing down inside after the blade has stopped. I can only guess that it's the bearings. Has anyone had experience of replacing them? Are they readily available?
Thanks
Chris

I don't know about pulling it apart but it looks like parts are available from the UK http://www.tritontools.uk.com/Triton...pricelist.html

It wasn't the bearings after all. The fan blade had come off its spline on the armature and was freewheeling. Don't know how, and luckily it hadn't been damaged or hit anything else. Pushed it back on and it's going fine.
There was a lot of compacted mdf dust around the housing, so took the opportunity to give it a good clean up.
Interesting to find that the saw has a gearbox to slow the blade down - I hadn't appreciated that before.

Spoke too soon. Did a couple of long cuts and it happened again.
I'll have to investigate a more permanent fix.

I'm not sure how the fan attaches or the fans' material - pressed on and splined? But with press fit items coming loose, or when we are fitting such items we use Loctite products. Check their site and look at which of the retaining compounds - 638, 648 or 680 best suits your actual situation.

Thanks for that - sounds useful. I was think of putting a circlip on, but Loctite may be a better option.
It's a splined fit with a fine spline all round - no keyway. The fan is made of pressed metal.
There is more spline on the armature that could be used, but then the fan would foul the locking mechanism for the shaft.
Looking at pictures of replacement armatures they look less likely to ride off, so it seems a change was made somewhere along the line.

Well, having looked at the price of Loctite (~$50 for 50ml) I might think about that!

If you know any automotive workshops, I'm sure they would have some and "gift" you a drop or two You don"t need much.

Looks like Loctite 660 is what I need, made for splines and comes in a small tube.

If the splines are worn, excellent choice.

I used the Loctite 660 yesterday and let it set overnight. Today I gave it a workout on some long pieces of Jarrah and so far so good.
Thanks Lappa for the Loctite suggestion.
