510 Link Belt

I'm posting this separately since I had to do an extensive search to verify that the correct length for the link-belt was the same as for the Mark V. IT IS NOT. The correct length is 32 (NOT 35 lengths). Installed it today and perhaps I should also post this on what I found when I did an exhaustive search on this site.

I replaced an almost new belt and the link-belt is much quieter and seems to run smoother. I haven't run anything under stress yet but don't anticipate any difference.

The Harbor Freight belt has 69 links; enough for a Mark V and a 510.

The Harbor Freight link belt has slighly longer links than the Power Twist link belt. I believe there is only 2 different lengths of 1/2" link belt links existing so 35 links for the Power Twist and 32 links for the Harbor Freight belt as starters.

I recommend operating the link belt of 20-30 hours to wear in the links segments and then check the internal clearance between of the link belt at the top of the control/Idler sheaves to the headstock casing when the speed control is set to SLOW. If you get a whinney noise at the slowest position, it is the link belt hitting the motor shaft so I adjust away from SLOW a letter or two until the noise stops. The link belt is still too short when you have the whinney noise at the slowest position. I may add or remove a link at that time to get the link belt even or just sightly above rim of the control/idler sheaves.

Bill, what you just posted is REALLY IMPORTANT TO KNOW. Otherwise several of us would be searching this site and the internet trying to figure out how to fix something. Thank you.
