Reference: "Parts List, Jeep Models CJ-2a and CJ-3a", 3rd Edition, printed 1949. Group 17-07, page 69. For sake of consistency, I'll try to use the same nomenclature that Willys used in this parts manual.
The Willys parts list is lacking complete detail of the column shift parts. There is no exploded view of either the clutch assembly, or of the gearshift lever. Some components are simply not identified at all in the parts list, while others are only included as parts of sub-assemblies.
*** NOTE: I believe ther's something "wrong" with one of the parts shown in this assembly procedure: the "Guide Pin". See the comments under the photo below describing the guide pin assembly, and also on the guide pin detail & drawing page.
Comments, suggestion and corrections are welcome.
Pictures below all link to higher resolution images (1024 x 768), if you want closer detail.

Housing & clutch parts laid out in order of assembly. From left to right: Control shaft: p/n 640608 |
The lower bias spring and its thrust washers are slipped on the control shaft. The upper thrust washer is held stopped by a cotter pin through the control shaft. (Note the use of temporary 6d nail in place of a cotter pin). |
||
|
The 1st/reverse clutch lever is slipped onto the control shaft, past the hole for the clutch pin (compressing the spring), and the clutch pin is inserted through the hole in the end on the control shaft. As shown here, the clutch is disengaged from the pin. |
The same as at left, but 1st/reverse clutch lever has engaged the clutch pin.
|
||
|
The clutch housing/bracket is threaded onto the 1st/reverse clutch lever.
|
The 2nd/3rd clutch lever is threaded into clutch housing/bracket. Lower end is complete at this point. |
||
|
The shift lever parts, left to right, top to bottom (excluding steering column): Control shaft guide pin (for lack of a better
word): not identified in parts list |
Here the guide pin is attached into the bracket on the steering column. This pin has a bore in the lower end (seen in pic at left), into which the end of the shift lever fits, through a slot in control shaft, inside the shift lever mounting bracket (more detail below) Normally held in place with a spring pin (6d nail used here).
|
||
|
The upper bias spring fits into a recess in the lower end of the guide pin. The control shaft then slips over the spring, the guide pin, and into the space on the column bracket. |
Here all the parts are slid completely together, The guide pin and bias spring are completely hidden. The rivet through the control shaft, at right, is the stop for the bias spring. |
||
The bore in the guide pin, seen through the slot in the control shaft. Note how the bore is misaligned with the slot in the control shaft. This corresponds very closely to the 20º offset noted in the guide pin pages. I think this is an error in drilling the hole. Things SHOULD line up! In use though, it shifted just fine. |
Now the clutch bracket is put in position on the steering column. A woodruff key in the bracket fits a slot in the steering column. Normally bolted down at this point. Another photo shows the clutch arms held in the neutral position during final shift mechanism adjustment. |

|
Back at the upper end, the shift lever is inserted into the bore in the guide pin and aligned with the bracket. My anti rattle spring is broken, so not shown. |
The fulcrum pin is inserted from the top, and fulcrum screw threaded in from the bottom. Assembly on the steering column is complete. |
