60.Using a soft mallet, drive the mainshaft forward in the case to free the mainshaft gears from the countershafts.

61.Remove the No. 2 (upper right) countershaft from the case by lifting the front end off the front bearing cone and then sliding the countershaft through the opening.

Removal is easier if the transmission is in the vertical position.

64.Using tool J 34630 or a slide hammer, remove the upper right reverse idler shaft (next to No. 2 countershaft location). To prevent damage to the reverse idler gear, catch the gear as it separates from the shaft.

68.From the top of the case, slide the mainshaft reverse gear and Lo/reverse sliding clutch forward toward the front of the transmission.

69.Using a pry bar, move the rear end of the No. 1 (upper left) countershaft away from the mainshaft as far as possible without damaging the bearing. Block the countershaft in this position, using wadding made from rags.

70.Tip the front end of the mainshaft outward and remove it from the case.

Be careful when handling the mainshaft assembly, the reverse gear is free on the shaft and can fall off during handling.
