Speedometer problem '48 Pilot House

[Monkey Truck]

My speedometer just quit working. Before it went dead, it spun around in circles a few times, went haywire, then just dropped to zero.

I removed the cable and re-greased it and it seems to be working fine.

I pulled the speedometer and tried to disassemble it to see if there's some sort of malfunction inside the unit. However, I couldn't get the chrome ring face that holds the glass off the housing. Seems as though the rings in each of the four mounting holes are riveted to the base.

Has anyone experienced this, or has any suggestions?

Thanks.

so let me help you with yours:

1. You mean the cable is working but the speedo is still going crazy?

That seems to be my problem too. It made some wierd noise and would

jump all over the place, so it's disconnected at this moment. I plan to use

some fine oil for the cable (bicycle chain lubricant) and then (and this is

what I'm hoping will solve the noise and jumping around...I think there is a

screw-post that exposes a felt lubricant blotter on the back of the

speedometer that keeps the speedometer mechanism oiled. I will lube

both the cable and the unit and re-attach the cable, then take it for a

test drive.

Are you sure you want to take it apart? (If it aint broke don't fix it)

2. I carefully drilled out the brass eyelets on both my speedo and instrument

cluster. The brass eyelets I am told are available at some hobby/craft

stores, but I used a S.S. phillips head machine screws and S.S. finish

washers in my re-assembly. I could always re-do them to original if I

found the brass eyelets and installation tool.

Hope this helps,

Hank

Thanks Hank. Yeah, it's just totally dead now, it won't read any speed. I tested the cable and the cable is working properly. I would rather not take apart the speedometer (don't want to open up a can of worms), so I'm not sure if that's even something that's worth trying.

there is a very fine circular spring just below the faceplate, my guess is that it broke. It is really fine and difficult to get to, I agree with sending it away

I just got my speedometer back in the mail yesterday from Scott's and it looks great. Not only did they fix it (rare broken part inside), they cleaned it up, repainted the needle and made it look almost like new. It was a little spendy, but worth the price.

Thanks again for the reference.

Guess all mine needed was a few drops of 3-in-1 oil and a saturated felt wick on back of the unit. Please post a picture of what Scott's was able to accomplish.

Thanks,

Hank
