Series 11 Drive Clutch Weights

A new series of drive clutch flyweights have been developed and are now available for purchase from Polaris. The new “Series 11” flyweights feature an aggressive shift curvature, and thinner profile.

Each flyweight is priced individually.

Drive weights are matched within .5 grams of each other and packaged in packs of three.

Weight / Part Number:
11 -- 70 / 1322523
11 -- 72 / 1322524
11 -- 74 / 1322525
11 -- 76 / 1322526

When compared to a series 10 weight, the series 11 weight has more weight distributed at the beginning of the profile curve and does not tuck under as much as the series 10 weight. Because of this difference, the belt--to--sheave clearance must be checked and washers may need to be added to increase the belt--to--sheave clearance after installing any series 11 weight into a drive clutch that
was previously equipped with series 10 weights.

The procedure for increasing the belt--to--sheave clearance by adding washer(s) to the spider is outlined in all Polaris snowmobile service manuals.

When cross--referencing between series 10 and series 11 flyweights, a series 11 flyweight will function similarly like a 2--gram heavier series 10 weight. For example, use a 11--68 when replacing a 10--70 flyweight.

more heel weight and less tip weight on the series 11's. they work better for lower rpm use or mountain sleds. the 11's come out of the hole better than the 10's, but the 10's work better at high speeds.

thanks for the info, I've been running polaris weights in my cats for years, but had never heard of the 11's which i saw in my new hpe catalog, looks like a few more sets of weights for the tool box.
