Then all should be good unless there is a manufacturing issue that we are not aware off! Did you change the pinion?

That’s what I thought but wanted to make sure.

Didn’t replace the worm drive as looked ok. Perhaps I’ll take it all apart again and check.

I mean the drum will pull in and out on the crankshaft which is normal but wear in the shaft or bearing will allow the drum to wobble on the crankshaft like if you put a ball bearing under the centre of a dinner plate.....well how else do I explain what I mean:confused1: It will....wobble!

I pulled apart again and I would there is wobble. I’m not sure how much is tolerable.

But cross referencing to the other two saws I had to hand, echo 2511 and a 200t, it seems similar to those. Can’t imagine there would be no wobble (for clarity as opposed to float in and out).

Find it hard to believe it can be wear on crankshaft as it’s not that old (2 yr approx) and I don’t use it even every week let alone every day.

Here’s a pic of the bearing on the crankshaft with me pushing it from one side to show the gap.



Enjoying the Arbtalk lessons. Thanks

Worm gear is obviously not perfect but doesn’t seem to be the issue....there may not even be an issue, I’m just wondering out loud really!!

I’ve just compared to another 550 and looks the same so I think I’m worrying about nothing. As you were [emoji23]
