Thanks Jon

i had that problem so had a heavy washer machined to put between the nut and the sprocket and was enough to get the sprocket on real tight.

Hi Team,
the sprocket hub protrusion measurement is so there is about equal compression on the sprocket bellows seals on each side of the sprocket.
With the sprocket being too far onto the hub, the inner bellows will be over compressed and the outer will be under compressed and so may leak both oil out and dirt in--brass bellows will likely split in the short term--as mentioned above track frame alignment becomes an issue and so can be hard to achieve a suitable alignment.
Cheers,
Eddie B.

the washer was only about 1/8 inch thick--so that would put it in 1/8 max---and being the track from had 1 1/2 inch toe out when i bought it and got it back to within 1/4 inch toe out i figured i was in the ball park--seems to be working ok after 5 years of use. And i believe the bellows seal is only on the inside surface of the sprocket
