. Weld spatter, dirt and dust can af-

fect cross slide operation. Mount

in a suitable location.

The 6-3/4 in. (171 mm) square mount-

ing hole pattern in the cross slide car-

rier permits mounting one cross slide

on top of another to provide X-Y

movement.

5. Bearing Adjustment Procedure

. Using callout items from the parts list to perform the following procedure.

The guide wheels are fastened to the wheel plate with special mounting bolts. These bolts pass through shouldered bushings that are inserted into

the guide wheel. There are two types of bushings; the fixed or concentric (callout item 12), and the adjustable or eccentric (callout item 13). The eccent-

ric bushing has hexagonal flats.

Pre-Load Guide Wheel Adjustment:

1. Check concentric guide wheel mounting bolts for tightness.

2. Loosen the eccentric guide wheel mounting bolt just enough to allow rotation of the eccentric bushing. Make the following adjustments in small

increments.

3. Rotate the eccentric bushing to a point where the guide wheels contact the track.

4. Hold the guide wheel firmly between your fingers and move the wheel plate along the track. At the same time, rotate the bushing to a point where

the guide wheel does not skid on the track. Tighten the wheel bolt snugly so that this temporary adjustment holds.

5. Repeat this procedure on the second eccentric guide wheel.

6. A proper adjustment is achieved by repeating steps 4 and 5 until a uniform resistance to motion is attained by “feel” along the entire track.

7. Fully tighten the eccentric wheel bolts to fix both adjustments.

. Both eccentric wheels need to be adjusted prior to performing this final tightening to avoid binding of the carriage.

8. Apply wicking thread locker to wheel bolt threads from top of wheel plate. Use loctite 290 or equivalent.
