Belt Drives EVO-11S - Manual (Page 2)

to HD specifications. (Electric impact is preferred).
For 1986-89 taper shaft models, you must use the
stock hub nut and seal kit included. (Fig. 5)
5a. For spline mainshaft models, 1990-up, apply
mainshaft when sliding the rear basket assembly
on. This procedure is necessary so that the hub and
mainshaft will fit together properly and will not let
the mainshaft spin inside of our hub. (This
procedure is not necessary on taper shaft models
1986-89). (Fig. 6)

Fig. 5 Pictured here is the seal kit installation which is supplied
with all 1986-89 belt drives only. A sealed hub nut is supplied with
all kits 1990- up. A stock HD hub nut with seal must be used with
all 1983 and earlier kits.
(The belt drive was designed with the use of stock HD frames. The shaft to shaft dimensions on a stock Softail is
12.825" and on an FXR it is 11.325". The number of teeth on the pulleys and the number of teeth on the belt was
engineered to exact fit using the above dimensions. If aftermarket frames, engines or transmissions are used then
these dimensions may very slightly, you may have to address this problem so that the kit will fit properly. We will
not be able to help you with this problem, this is an issue to be addressed by the manufacturer of the after
market parts that you may be using.)
