Question about RCA CC4252 Camcorder
It's been a while since I worked on the RCA full size camcorders as well. It sounds as though the load motor is "jogging" because the mode switch is not in time with the mechanism. I think there are timing marks on all the cams and gears in the unit and an indicator arrow on the mode switch. Set the mechanism to the "stop" mode and align the main cam index mark to the load motor drive cam, be sure the mode switch arrow points to the load motor drive gear "hole", this tells the micro the unit is in "stop" mode.

Tips for a great answer:
a flat screwdriver to unseat the tabs that hold the front top cover
in place. This will expose the flywheel and pedal arm connection
points. Rotate the flywheel by hand and determine whether lubrication
will accomplish the repairs. If the bearings are exposed, use a
grease gun with an extension nozzle and lubricate both bearings with
lithium grease. If the bearings are damaged or sealed, proceed to the
the front and side covers on the main frame. Hold the flywheel with
one hand and use a box wrench to loosen the bolts that secure the
pedal arms at each side of the flywheel. Pull the arms away from the
flywheel and remove the bearings from each side.

grease and reinstall them. Sealed bearings must be replaced. Reattach
the pedal arms to the flywheel. Replace the main frame covers and
front top cover to complete the repairs.

owner's manual for the exact type of grease for your unit.

joints and attachments with moving parts such as handle bars, wheels,
