DRIVE GEAR TRACKING

The TC-3 is shimmed at the factory so that the drive gear sits flat against a .88” (22mm) flange when the release handle is in the up position. If the flange dimension is other than .88” (22mm) the shims under the TC-3 gear box mounting will have to be changed accordingly. See Figure A.7.

TC-3 units are shipped with a helical tooth NOTE: drive wheel that is suitable for use on a smooth drive rail. A straight tooth gear (T13586) is available for use on a drive rail

with a straight cut knurl.

CARRIAGE BEARING TRACKING

Bearing tracking can be checked by placing a strip of white paper over the area where the bearings ride. With the drive gear disengaged (handle down), move the carriage over the strips. If the tracking is correct the bearings will leave a uniform trace on the paper. See Figure A.8. If traces are not corrrect add shims as necessary. See Figure A.9.
