Assembling Transmission

Assembling Transmission

Place reverse idler gear in transmission case with the flush side of the gear to the rear of the case.

Next insert transmission reverse idler shaft through case and gear, turning it so that the flat side of the shaft faces countershaft hole in case (See A, Fig. 481). This lines up the shaft so that it can be locked in place when the reverse idler shaft retained is installed.

Place a little cup grease on the sides of the two thrust washers and position them in each end of the transmission case so that they line up with the transmission countershaft holes in case.

Next grease the two countershaft gear bearings — short and long — and insert a bearing into both ends of the countershaft gear assembly. The long bearing fits into the end of the small gear. (See Fig 479)

((479))

After inserting the bearings into the ends of the countershaft gear assembly place the assembling in the transmission case, meshing the small countershaft gear with the reverse idler gear.

Next line up the two countershaft gear thrust washers and the countershaft gear assembly with the countershaft holes in the case and insert countershaft through washers and countershaft gear assembly. The shaft is tapped into place with a brass hammer. When installing turn the shaft so that its flat side (See A, Fig. 482) faces the flat side of the reverse idler gear shaft.

Next place reverse idler shaft between flat side of shafts and fasten it in place with lock washer and screw. (See Fig. 477)

Line up the transmission low and reverse sliding gear with the transmission high and intermediate sliding gear, making sure that the faces of the grooved collars come together (see A, Fig. 483) with the small gear to the front of the case.

((483))

If a new main shaft or a high and intermediate sliding gear are to be installed, select the parts so that the gear is a snug sliding fit on the shaft. The gear should have not more than .002” clearance on the shaft (check with feeler). The clearance my vary from .002” down to a point where the gear will just slide on the shaft of its own weight or with a slight pressure of the fingers when the shaft is held vertically.

((484))

After lining up the gears insert the transmission main shaft B with ball bearing assembled, through the rear end of the case and through the low and reverse and high and intermediate sliding gears. The shaft is guided downward until the transmission main shaft ball bearing seats into the bearing seat in the case.

Next place bearing retainer gasket on end of transmission case and assemble transmission main shaft bearing retainer to gear case by installing the four lock washer and cap screws. These screws should be drawn down tight and wired. When installing retainer be sure it is assembled with the lubricator fitting pointing downward.

Next place pilot bearing over the end of the main shaft and collar assembly, then place transmission main drive gear over bearing on transmission main shaft, making sure that the main rive shaft ball bearing seats in ball bearing seat in transmission case.

Position clutch housing to transmission case gasket on end of transmission case and assemble clutch housing to transmission case (See Fig 484) by installing the four cap screws. The assembly is then installed in the car as described in the February Bulletin.

Before installing the gear shift housing see that the gear shift housing gasket is in place on transmission case, the gear shift lever in neutral position and the transmission gears on the main shaft are spaced so that the gear shifter forks line up with the collars (See A, Fig 485). Next pour in sufficient gear lubricant until it reaches the level of the filler hole in transmission case.
