Does anyone have measurments for antiratchets i seem to have lost mine Thanks Dan
Diameter on drive sprockets with 2,52" pitch:
7T = 5.50"
8T = 6.25"
9T = 7.05"
10T = 7.85"
7T = 5.50"
8T = 6.25"
9T = 7.05"
10T = 7.85"
sorry need spacing from end of shaft 01 700 mm
i treat each shaft differently based on what antiratchets are being used and came up with a fairly straightforward procedure. probably not the cut and dried answer you were hoping for.
due to the variances in hub widths, depending on supplier, i simply find the center of the shaft based on the location of the stock drivers. measure the distance between the two inner drive wheels and locate center(1/2 the distance) and mark it with a good sharpie pen or metal scribe.
you want your antiratchets to be between 8 7/8" to 9" center to center, depending on the track. (measure the track windows center to center). installing the antiratchets slightly to the out edges of the windows seems to make the track run straighter.
now measure the width of the hubs on your new drivers, do the math off of center and factor in your window centers along with the desired center to center on the drivers. take some notes and press away.
be sure to align the timing marks on the drivers. as mentioned, suppliers differ in hubs, and even from set to set. also, some hubs can actually swell a bit in the pressing process so use the drive lugs and a square for your final measure.
