The H9 thru H32 (.287” thru 1.00” diameter) Cam Followers require a Steel Ball/Set Screw and
an insertion gage for installation. The steel ball/set screw is used to anchor the cam followers
to the follower wheel and the insertion gage kit is used to insure proper installation. The new
cam followers need to be pressed onto the follower wheel to the position prescribed by the
gage (if they are pressed in too far, the will not turn freely).
Cam Follower Installation Procedure
1. Obtain spare parts kit, cam followers and insertion gage kit.
2. Select proper insertion gage. The spot-faced type gage should be used if the cam follower
mounting surface is spot-faced. If no spot face is present, the flatted type gage should be
used (see gage illustration, above).
3. Place insertion gage around the outer diameter of the cam follower while pressing onto the
follower wheel.
4. Refer to the following chart to determine if the steel ball and set screw or the set screw
only* should be used for anchoring the cam follower. The anchoring hardware may not
always align exactly with the groove on the cam follower but it will always align within an
acceptable range. The cup point style set screw is always required.
* If steel balls and set screws were supplied with the original unit, continue using steel balls and set screws (reuse
original set or use set provided in the spare parts kit).
