BT3000 Stripped arbor threads

[Roy]

Hello,

I am in line to pick up a moderately used BT3000 for $75 locally. The owner says that the arbor itself and the arbor nut is stripped. Looking at the ryobi web page it says a new arbor is around $11.00. Is it relatively an easy fix and a pop-in replacement? And is that really the going price for a new arbor? If that is all that is wrong with it, is this a good deal? Thank in advance.

I'd have to say that if the arbor is stripped there could be many more issues with the saw. I'd be hesitant to spen $75 for a saw with that problem. I can only guess on the cost and availability of an arbor but yes it is a simple drop in replacement, well maybe not simple and maybe not drop right in but a direct replacement without the need for fitting. I've not done so so I'm also guessing here but I'm thinking you'll at least need gear puller(s) and a press for reassembly.

the arbor is probably not that easy to replace.
Besides, i wouldn't buy a saw from someone who stripped the arbor - indicates a hamfisted owner...

I agree.

Putting in a new arbor is going to require new bearings (in all likelihood) and unless you know that there is nothing else wrong, may be a complete waste of time.

If you could get the saw for 25 bucks, it might be worth it. Then you are only risking that much assuming it can't be fixed. A new arbor will require the gear puller and/or a press. A machine shop could do this for you without too much trouble but it will cost 30 or 40 bucks.

Ya, you have to wonder how the arbor threads got stripped in the first place.

[LCHIEN]

on second thought they could have just been cross threaded.
If that's the case you could rethread them... but its a left handed thread, the die would be hard for me to find.

I would think the arbor is a lot harder than the nut which is a dull, brittle alloy... the arbor would have survived mostly a cross threading. As I have put forth before, you reallly don't have to crank hard on the arbor nut, just snug. The nut self tightens when rotating the correct way (which is why they used a left-hand thread, so it doesn't loosen.

Does the original owner know about that left hand thread deal? It is possible he is trying to put a rh hand nut on and it won't go and he assumes it is cross threaded.

BT3000 stripped arbor threads?

I would be a little leary of that saw from the start..... I'm thinking that he is
a type of owner that did not take care of the saw and read his owner's manual
before using it. Why not try and run the saw with no blade and see if there
are any issues with it before buying ? If the motor and controls seem ok, then proceed from there to purchase. I would try and find a local machinist who could re-thread that arbor with the proper threads and then install a blade and see
how well the saw would cut. You might end up with a decent saw for a small investment...who knows?
