First drive of spring

[Young Ed]

The 48 started on the third set of pump pump pump crank crank crank. Drove the first 100 of the 120 miles home without issue. Cruising along at 60 and the speedo jumped down to almost 0 and then sprung back to 60. Odometer never turned again. What happened?

Hey Ed, glad the ride was fun, the darn odometers, mine has done the sticking thing too, the speedo, and trip odometer is fine though........

Something be stuck somewhere. These cars are never done and always need TLC but isn't that why we love them. Seriously, hope it is a simple fix although removing the speedo unit is always a fun job.

No trip odometer on the lowly plymouth. I have one busted up speedo and I think maybe one intact one to try and get a repair part from.

Glad you got it out and home. Look forward to seeing you with it on the road.

For what it is worth, the odometer on my '41 was not working. I had a spare speedometer from another '41 that I planned on swapping in. When I removed the broken one and compared the two, I discovered that the internal mechanisms were different even thought the outside faces were the same. Different suppliers? I ended up having to replace the odometer number cylinders and it works fine. My point is that you may find that the parts do not swap from one unit to another.

Jim I have noticed the same thing in the p15 ones and in my 39-47 dodge truck ones.

I haven't had those problems -yet - but of course my speedo reads about

15 mph off and the odometer isn't really accurate, but it's turning. It

seems to operate ok in warmer weather, but when I drove it a couple times

this winter, the needle jumped way up to the high side and was crazy.

So, I just unhooked it til things warmed up. When I drove it in cooler

(but not real cold) temps about a month ago, it was behaving fairly normally again.

I have two or three other speedos, including one that appears to

possibly have been worked on once years ago.....will try them out

when it's warmer and I get in the mood to stand on my head (under

the dash, that is). I tried taking out the bottom cushion of the seat,

but then you still have the frame to contend with. So I'd just as soon

leave the cushion and work on the slant.
