1970 steering column question

[davek]

so just the 4spd and auto on floor have this key release? This would not be for cars auto on the column? thanks Dave

 

[dadsbee]

No such beast on my '70 floor shift, that's what the one year only lock out linkage is for.

 

[davek]

This is not supposed to be on my car,71-79

 

[davek]

were dos it bolt up to?

 

[davek]

is the 4 way on the column?

 

[dadsbee]

Yep..

Can't help with the linkage attachment, I have no pics and haven't seen the bottom of my SB in over 20 years. It'll be on the hoist in the months to come when I get it ready for Talladega... but not sure when that's gonna start.

OP pic looks like 72-74.

IIRC 70/71 had a thicker "push to release" button without the thin extension designed for a sticker which said so.

Yeah, dadsbee is correct. My '70 doesn't have that key release lever at all.

 

[davek]

can I use the column without the lock out linkage?

 

[dadsbee]

Cleaning up my work bench and found this that I printed out... from here! Can't find the original thread it came from. Got under my car to find my linkage is gone, other than it looks correct from the engine compartment with a link on the column lever. The link rod is just jammed up between body and frame rail to hold it in "park" so the key comes out.

 

[davek]

so the interlock does not go on a 4spd? thanks for your help dadsbee.

 

[dadsbee]

I actually believe there is an interlock for the '70 x 4 speed and you have to put it in reverse to get the key out.

1970 was the first year for the steering column mounted ignition switch. This included a steering wheel locking mechanism for the first time. The lower column head casting is what locks the wheel and prevents the ignition switch from allowing the key removal while the wheel is unlocked or in gear. For ’70 the lower column casting is connected to a shift tube that would be used for a column shift automatic. Most of the “’70 Lock out” linkage is the same as the automatic column shift linkage. As mentioned, on a 4-speed, it needs to be in reverse, has an additional rod from the lock linkage to the reverse lever on the 833. For floor mounted automatics, it needs to be in park.

Starting in ’71, the gear lock-out was omitted, no longer had the shift tube in the column and lockout linkage on the floor-shift cars. The lower column casting still locked the wheel but had the manual tab and provisions for a label cast into it. Picture above is the later casting. With the later design, the casting rotation direction to the locked position is reversed from the ’70 version as well.

On a ’70 column, using it without the lock-out linkage would require the lower casting and shift tube to be fixed into the unlock position. However, this could allow the wheel to lock if the ignition switch is ever shut off for any reason in while the vehicle is in-motion, as there would not be anything to prevent the ignition lock from going back into the wheel locked position.

As stated by 72RRGTX both auto and 4 speed on floor had the lockout. In fact the tube is the same with the lever. Only the manual three speed on column had a different shift tube.

Yes you can use the column without the linkage attached. The housing turns by hand. Many folks disconnected that linkage in the day.

Obviously the column auto did not need the linkage since the shift handle moved the column housing and would only allow the key to come out when in Park. But again it used the exact same shift tube, the linkage was just connected to shift the auto transmission.

A floor shift housing is round/plain. Shown, is a 70 Coronet housing set from column auto. The bottom housing has the mount for the shift handle. A Floor shift would be solid with no mount. Also no shift indicator on the other 2 housings.

Was looking for something else about my hubs Dave and found that the ENTIRE exploded view, of every part and attachment of the lock out, is shown in the 1970 FSM !

 

[Dragon Slayer]

The parts manual, also on line, have great diagrams too. Helps with assembly.

 

[davek]

I looked at manual on my mopar and didnt see it.
