Looking for a water temp sensor for a DD 6-71 from the 1959. Any suggestions as to who might have one or a replacement for it?

Thanks
 
Hi,
I don't know for sure but, if you have the old one, it might match up to something they have on the shelf at NAPA for old GMC trucks. Or, just get a later, skinnier one and bush the hole with a brass adapter. Those sensors were NTC carbon and were pretty common back then iirc.

As to your alternator question in another thread, I don't know that answer either. I haven't worked on a 6-71 since the 90's and, even then, the in line engines weren't really used in industry very much and reusable parts for the V engine were getting pretty rare.

You might try to find an old bus boneyard. They might have what you need but I'm guessing they're going to want some serious money if you can even find a match.

I think I would first look into maybe finding someone to rebuild the thing for me.

Sorry I couldn't be of much help.

Good luck.
 
Thanks for the reply. Getting harder and harder to keep her running!

Any suggestions on someone that might rebuild the alternator? Likely not a cheap date either but...
 
Approximately where are you located? I'm still a member of iATN (international Automotive Technicians Network) and will ask for rebuilder suggestions on the forum.
 
Apologies, I was thinking that you have the old gear driven generator mounted on the gear housing at the rear of the engine.
Now I realize that it's much more likely belt driven off the crank pulley. Is that correct?

If so, I remember that we used to use the Delco Remy "one wire" alternator as a cheap, easy to adapt replacement on just about everything in the field that could drive the pulley from the crankshaft if you select the correct pulley diameter and length of the belt.

I Googled them and see that the GM "style" is available from.Jegs , Amazon and other upfitter outlets in 63, 80, 100 and 140 amp versions.

Anyway, if you only need it to charge a starting battery and possibly run a light load like instrument panel and running lights, 63 amps should be enough to get the job done.

Lots of pictures and wire up diagrams on the net for them.You may need to fabricate a belt adjuster or mount bracket
but I think that they fit many applications right out of the box. They are also inexpensive enough to allow you keep a spare or two on board.

Good luck.
 
You can buy anything to rebuild a 71 series. A 1959 probably had a generator and the alternator replaced it. I have 671 twins from 1947. No problem rebuilding. I put 4 valve heads on.
The sender for the water temp gauge is standard. Any autoparts store should have one.
