Heavy Duty Planetary Rebuild Kit1.76 Ratio
Sonnax offers the HD planetary rebuild kit 28922-01HDK, which includes several heavy duty components and all the parts needed to rebuild or refresh a Powerglide planetary with 1.76 style pinion spacing, including Sonnax 1.80 and 1.69 ratio carriers. This kit is a substantial upgrade for greater reliability, wear resistance and longer service life in the Powerglide® planetary. The pinion thrust washers are steel-backed, bimetal washers impregnated with a very wear-resistant PTFE layer to reduce friction and stress from rotating pinion gears. The figure 8 thrust washers are further strengthened with a wider web between the two ends. The retainer plate is heat-treated steel and tougher than standard plates. The rear sun gear thrust washer incorporates an enclosed thrust bearing within the thrust washer that eliminates compression and distortion of the standard thrust washer due to input shaft thrust loads.
