odometer & Tripometer

[Gerald C.]

Neither of these work on my 1967. I've moved the tripometer to hopefully get the odometer moving and nothing registers.

Is there a way to fix these without taking the cluster out?

Thanks
Jerry

Jerry,
I would start with the easy way first. Pull speedo cable and see if cable is broke.

If not broke, check that gear is in tranny.

If it is, hand turn, drill is better, cable (with wife watching gauge) to see if needle moves.

If not check back here.........

Re: odometer & Tripometer

Gerald let me add to Gene's post. If the Speedometer is working it's internal to the Speedometer. I have had this in the past and it's a gear in the speedometer. Others can maybe tell you what gear. Symtoms are speedometer works, but odometer and trip don't work.

Re: odometer & Tripometer

One thing to look for on the trip odometer is that the cable from the cluster must pass through the hole shown in the picture below. If it is not routed through the hole, the cable will kink and bind and the Trip Odometer will not work. I learned this the hard way and it is not shown in the AIM. You can do this lying on your back or maybe take the seat out. PT

My apologies...I should have mentioned that the Speedometer works!

PT,

Nice signal switch. Is that a replacement cam on your original or is that a replacement switch?

Jerry, I bought that NOS switch from LICS for $70 and the guy there told me that was the last NOS switch they had for '67's. PT

Gerald -

Very common/chronic midyear failure in the odometer gear train (doesn't affect the speedometer); the speedo assembly has to come out for repair (which means the cluster has to come out first).

Thanks everyone. Looks like a winter project!

Pat , do u mean that the speedometer cable must pass through this hole or does the cable from the tripometer pass through this hole ? Secondly, where does the speedometer cable pass through the firewall ? thanks Del

Pat , I asked a dumb question about the hole and cables , I looked on my dash and realized the speedometer cable would never be able to go through that hole . By the way couldnt find the tripometer cable in the AIM ... . Del

Re: odometer & Tripometer

My trip odometer/odometer let go at about 35k on my 63. I had to replace the brass gear which was chewed up. Has worked fine ever since until today (45k), knock on wood, but I am still afraid to use the trip odometer for fear of incurring the same failure so I just let it go w/o resetting. With the cluster out, it is an easy fix. Getting the cluster out is the pain.

Del, it's on page G235 but it doesn't show the detail of the cable going through the hole but it's gotta go thru the hole. PT

Patrick,

There is a page in the '67 AIM that looks almost the same as your photo, UPC 1Boltweld-A9 (G43 in my AIM). There is a GM 3826920 U-Nut Asm. called out (Item 22), looks like it implies there should be one for each of the Item 23 bolt & L.W. assemblies across the top of the instrument panel. This is the same U-nut part number that is used at the rear of the parking brake cover reinforcement (1ASM-F12, item 4) and one is also used on each of the four front grille brackets (UPC 11-13-B1, item 7).

I don't have any of these clips at this location, and I don't see any in yours.

Is this an AIM error, or should there be U-nuts under each bolt w/attached lock washer?

Scott -

Those item #22 U-nuts go in each "window" opening in the lower windshield frame, and accept the #23 bolts that attach the main dash panel; the U-nuts can't be seen with the main dash panel installed, as its front flange covers the lower windshield frame (except at the openings for the lower garnish molding nut locations - 1Asm, F19, View A).
