Re: V-belt replacement
I have a pic of the motor pan. But can't figure out how to upload it from my android picture gallery! It won't attach,and I see no error message.

Now my belt at fast(riding ABOVE the outer rim) clears the way tube by about 1/4".
i.e. It does NOT interfere?????
I am wondering IF the control sheave is not open as much as it should. But that would lead to suspicion of belt length etc..

Re: V-belt replacement
All the post I have read and videos say to set the high speed or 5200 rpm the belt should be running at one sixteenth to one eighth inch below the motor sheve. In what condition would the main belt run in the higher position you describe?

Re: V-belt replacement
I bought the belt from Jacob Anderson. They must be working on others.

Re: V-belt replacement
"MY" procedure is to set the high speed adjustment so the belt rides the same on the motor pulley at fast as it rides on the idler pulley at slow. I feel that evens out any things that are 'weird'. The idler pulley limits the range of adjustment available(the motor pulley merely responds to that so as to maintain belt tension). I think the belt is slightly 'narrow' since it is an off the shelf automotive belt.roneg wrote:All the post I have read and videos say to set the high speed or 5200 rpm the belt should be running at one sixteenth to one eighth inch below the motor sheve.

As I mentioned the headstock is not 'standard' since it has poly-v stuff and a non-standard belt as well as an altered motor mount. FWIW the motor is also reversible. The poly-v belt tension(eccentric setting) is set near 7 oclock(new belt). That makes the motor offset less that if the eccentric was adjusted for increased tension(towards 9 oclock).
I will review this thread so as to maybe solve the mystery. Something is being overlooked. Not tonight!

Re: V-belt replacement
The eccentric does alter the position of the idler shaft but I seriously doubt enough to cause the belt to rub the tubes. My eccentric is set at about 7 o'clock.

Re: V-belt replacement
Upon reviewing this entire thread, no flash of inspiration occurred.
The Jacob belt, though not 'oem' dimensions(?), I agree should be close enough and not cause this tube rubbing problem.
I am actually back to what I said above re the control sheave not opening sufficiently to move the belt away from the way tube.(as the belt moves towards the outer rim of the motor pulley[closer to the way tube], the control sheave should be opening).
That is not satisfactory since it earlier it appeared the idler pulley was TOO FAR open causing he belt twisting in side out.
I am left only with suspicion re the assembly of the idler shaft etc..
We have not examined it closely(no pix). There is also the concern re the Gilmer belt riding too far to the rear.
So I think the next step is to take a close look at the idler shaft etc. from the quadrant loop to the external shaft.
It was mentioned earlier the PO had the motor 'rebuilt'. I do not think that has any relevance to this problem.

Re: V-belt replacement
Take another showing the idler sheave and back towards the rear end of the idler shaft. Should show idler sheave, gilmer pulley/belt and casting with retaining clips.
I notice a couple of things(not necessarily related to belt problem).
The casting is fractured and apparently a piece is resting on the quill in the first pix.
The seal material from the idler bearing is coming loose?
