DZ170 CDI High-Load Cam Follower YSE1236 by YS Engine  [YSE1236]

High-load cam follower for DZ170 CDI

This cam follower is an RC-scale replacement designed for the DZ170 CDI ignition assembly. It transfers motion from the rotating cam to the valve actuation gear on small two- and four-stroke RC engines, helping ensure steady timing under tuning and running conditions.

Produced as a serviceable spare, this part addresses wear at the contact interface; installing a new follower removes slack in the cam train and helps restore precise timing without changing internal components. It is supplied as a single item for scheduled inspection and swap-out during engine setup.

Fitting the follower is straightforward for experienced hobbyists: remove the ignition or cam cover, inspect the seating and cam face, replace the follower with the cam at rest to prevent misalignment, and reassemble with original fasteners. After fitting, re-confirm timing and smooth cam operation before calibration runs.
