SPICER/NAPCO AXLE Caterpillar


Notes On Testing

Usage:

If properly installed, the rotating (or overrunning) wheel should cam out easily by hand, rotate freely in both directions (steps 4 and 6 and steps 4B and 6B) until the direction of rotation is reversed unless reverse pressure on the opposite wheel is relaxed.

With the standard-type No-SPIN, the clicking or indexing noise is normal and quite prominent as the driven clutch alternately disengages from the spider and then re-indexes with the spider during the time it is rotating.

With the silent-type No-SPIN, however, only faint indexing noises will be heard, and possibly none at all until the direction of rotation is reversed when the clutch will re-index and a slight indexing noise should be heard. If you do hear repeated loud indexing or clicking sounds when checking a silent-type No-SPIN, one of the holdout ring and clutch assemblies may not be properly assembled to the spider. (If a No-SPIN is disassembled for any reason, be sure to see the service section for proper reassembly.)

If either wheel (with either type No-SPIN does not rotate or cam freely in both directions, recheck each step in the installation procedure. Also, check both hand and foot brakes for possible drag caused by improper adjustment. Check again to be sure taht all thrust washers have been removed.
