the wheel drive assembly approx. 1-1/2 in. (38 mm).

15. Ease the wheel drive assembly back into the windrower
leg, but don't push it all the way in tight. Adjust brake
line so that it is once again vertical, and tighten fitting
(A). Push wheel in until you can still see the bolt heads
at (A), leaving a gap of about 1/4 in. (6 mm).
NOTE:
On the left-hand wheel motor there is a speed
sensor. Be careful not to damage it when
reinstalling the wheel drive.

remove the two hex bolts (A) at the center of the drive
wheel. Remove cap (B), and flip over so that the dished
side faces in. Replace bolts (A). The cap will press on
a pin that disengages the gearbox.
