Default Tilt lock repair

I finished reassembling my steering column yesterday after fixing the lose bearing and worn tilt pins. Now I have a problem I cant find and answer to from searching. I have only found results for lose screws, bad bearings, incorrectly assembled bearing, or worn pivot pins.

The tilt adjustment wont lock. I can move the wheel up, and down the same way as if pulling the tilt lever with out touching it.

Page 36 in this .pdf is the spring etc involved with latching the detents for the tilt:

This is a Fiero column with some differences in column-lock but all else is very basic Saginaw.

That spring is installed correctly. For some reason I always get the weird problems. It looks like I need to disassemble it again to try and fix this new problem.

You can assemble missing the detents but it's pretty difficult. Look at pages 27 - 29 of the .pdf.

I have the column apart again. The detents are there, but will not catch the pin on the other side to lock the column. They try and catch, but if I bump the wheel they wont hold.

I haven't had one apart for quite some time but you need to install the tilt lever and pull the lever towards you for the detent pins to slip between the housing and the two levers with the notches. Easier for me to do than to try and explain.

Go back to the .pdf at maybe page 26 or so and it's described pretty well. Maybe start at page 23 and then go forward. I don't think the detents are actually engaged and the housing ready for the pivot pins until maybe page 30.

3F5B-14, 15 or maybe 16 in the FSM depending on year.

Looks like I need to find a replacement detent one of them got bent somehow, and I think that is the cause of the problem.

I doubt you could bend one. They will appear somewhat staggered because the teeth are segmented so that there's only a 1/2 click on each for adjustments. Both aren't latched at the same time. Here's an eBay housing that you can see the stagger in the detents. This is normal. Could you have bent a pin in the other half of the housing? Maybe but I doubt.

You'll have to remove the tilt pivot pins to start over and I believe you realize and have done that or you couldn't see the detents.

Patience LOL

I learned something new. There are at least two different designs for the detents, and at least two different pin setups. I replaced the part of the tilt housing you linked, and it does not have the correct detents. The lower half of the tilt has 2 pins with different sizes. The replacement housing is setup for one pin in the lower half.

Its not as good as I was hoping but better then it was before, and it works now.

Yep. Dave has provided one of the best guides to rebuilding the Saginaw columns available. I used it to rebuild a '90 model Jeep tilt with great results. Since the tilt Saginaw is in all GM and most Jeep vehicles of our era, the Jazzman .pdf is very useful. I wish it woulda been a Vette collapsible column but that part isnt hard either.

The telescoping/travel aspect of the column is the same/very similar to the C3 and of course Cadillac. I've posted this before I'm sure but if you really want to do the upper tele/travel use Jim Shea's papers:

Nearly anything Saginaw related can be absorbed from his very well documented papers. Gear boxes and racks also.
