Re: {Chrysler 300} 1962 Speedo Cable Question....

I think you can simply epoxy or JB tip back on , after cleaning off any oils . ( brakecleen) almost no torque there IF speedo is as free as it should be . Should spin totally freely .

All of the other email is right .

The square tip is used with a universal cable kit , to allow cut and fabricating the round cable to length . — that crimp not being done right or loose is not uncommon . You can buy the universal cable kit at auto parts store. — was the old one snapped? Also new one may have saved your speedo if it backed out of the crimp due to stuck speedo overloading it .

The oil inlet for bushing on some has a screw or cap (1/4-28) but later have a pressed in indented cup you cannot get out unless on bench .

Sometimes missing the cap , 1/4 28 allen set screw works.

however I have been in there 7-8 times over the years, and while the inlet bushing can and often will seize , they lubed some small gears inside with really junk grease that turns to a rock . Sometimes white grease ( worst of all— that stuff is junk) or hard dark front end grease .

What gets greased are the odometer drive reductions . At least one is nylon . So if stuck there and then forced , the nylon tooth strips . = screwed . Been there.

About 1/2 of the ones I got into had locked up odometer drive problems — and the bushing too. If cleaned and lubed first they worked ok . I use 75w mobil one , oil , it stays and cannot harden inside . Bushing a lighter oil

For these reasons taking it out just makes sense .

If you do this yourself , be extremely careful not to touch or bend extremely fragile aluminum cup the needle moves with ,, I just grabbed the first one I did — to pick it up — and bent it , ( cup projects out, of course) then it scraped , could never get it right again ( needle will erratically wave way up and come back again )

Sitting at 15 mph may be a simple zero adjustment — easy . When out .

or someone has been in there .. hope not .

Or — if stuck odometer is not addressed , and then you fix by “freeing it up “, you have no odometer . Can’t tell from

outside of it ...

Also , kind of a takeaway , speedo shops are pricey but so is 150

speedo .. once out ? FYI The 120 needle spring is different will not track on 150 , ( I tried swapping whole works into 150 face) that whole needle / spring part of it is unfixable , for me anyway . All pressed together fragile little pieces like a wristwatch , cannot get apart , hairspring bends instantly . once bent , done for . slow easy very gentle is the rule ..

Good luck ,

ps also a long thing elsewhere about worn lower needle / cup support bushing , also causes jumping,( cup gets misaligned) but that is a high mile thing)

Yes, you can pull the cable from the housing. Not sure what you meant by " The cable tip ". How long was that cable tip ? If its brand new maybe they will replace the cable or repair it. Send pictures.

If you install a good cable to the transmission and the speedometer and if the speedometer is frozen you can break the cable inside the housing. The cable will spin at the transmission end and with the speedometer end not spinning it will twist momentarily and break.

There is a small oiler hole at the top of the speedometer . I had one that was frozen and with time and patience you may be able to get it loose without removing it from the car. get an inspection mirror and you will see it.

First of all, protect your carpet.

I first sprayed it with PB blaster. Other penetrants should also work. You only need a little bit. let that soak in. Another shot, soak in, another shot, soak in. I have a short piece of cable ,about 6" long, that I then inserted in the speedometer. By hand try to twist the cable back and forth. If is does not move do more PB Blaster. Let it soak again and try twisting the short cable end.

Once you get your speedometer head free it may go back to resting on zero. If not you will have to remove it for repair.

Once I got it free I then put a drop or two of lite oil in the oiler and let it soak in. Let that soak in and add two more drops. I used sewing machine oil. Once it was oiled and spinning free I inserted the other end of the short cable to a cordless drill and spun it. I think the drill had to be in reverse.

With patience you may get this speedometer head free again.

Others may reply with other ways to get this free.

Good luck and have a Merry Christmas and a Happy New Year !!!!

The History / Issue:
- 1962 300 Sport - Sitting for 8-10 years playing dead; after I cracked the 413 block, living on the 405 freeway in So. Cal; ugh!
- My wife bought the car in 1989 & wasn’t too pleased with me overheating her car; as she had built that 413 with the dual inline carbs
- It has a 150 speedo, that worked fine many, many years ago.
- Now my 17 year old has rebuilt a 383 for the car, installed it & we picked it up from the brake shop today.
- The speedo seems to be frozen at 15mph.
- I unscrewed the (brand new from Imperial Services) speedo cable from the back of the speedo head…the cable tip fell on the floor
- I suspect the speedo was frozen….the cable was spinning in its housing….and separated the cable tip from the flex cable
(I will get under the dash tomorrow…take the speedo tip & slide t back into the speedo head….see if I can rotate the speedo one way or the other with my hand. I suspect it will be frozen. Then what? Pull the speedo out of the dash?)

The Question:
- Can I pull the flex cable out of its housing…had the tip re-crimped back on…slide the flex cable back in WITHOUT pulling the transmission end out of the trans & thus its fluid?
- OR - Do I need to pull that speedo cable off the side of the transmission, capturing the trans fluid & pull off the speedo gear to be able to slide out the flex cable?

Thanks!
