The first and most important step in cam maintenance is inspection. Inspect your cams frequently. If you have any
reason to doubt the integrity of a caroming unit (or any of your gear) heed your instincts and retire it. If it is a
Metolius product, you can send it to us or inspection. You should destroy retired gear to prevent any chance of
Look at the teeth on your cams. If they are worn unevenly, it probably means that the cam has lost its shape and
is unsafe to use. Check for slop between the cams and the axle. There should he some free-play, but too much
play indicates that the axle holes in the cams have become oval. Compare the free play to a new cam to get an
idea of how much is acceptable.
Inspect the cable body carefully. It is okay to tweak the cable to straighten it after a fall, but if any of the wire
strands that make up the cable have been broken or severely kinked, the unit needs to be retired. Look at
the springs and cam stops, which can break if the unit is improperly placed and then loaded. Also take a look at
the axle. It's possible to bend the axle of a small unit in a hard fall, in which case it needs to he retired.
The most likely place to find damage to your units is the trigger wires or the sling. You can tweak the trigger
wires to straighten them if they become bent. Try to adjust the wires so all the canes retract at the same rate.
When fully retracted, the cams should meet in line with the stern. Keep an eye on the swaged joint on the
trigger wire. It is the most likely place for the wire to fray. If the sling or the stitching show major signs of
abrasion, or if any of the stitching is broken, the sling must be replaced. Metolius will
