 Topic: A/C HD16DP charging generator source?
Posted: Yesterday at 4:12pm |
|
Anyone know if a 1966 A/C HD16DP charging generator... even used... can be had? The one on mine has never worked since I have had it and I am just getting around to addressing it. Also... if the specs... i.e. output current and voltage is known that would be greatly appreciated. I know the system is 24 volts but I have to believe the generator output is a bit higher than that. I know there is a regulator involved as well.

I converted a couple of Caterpillar bulldozers to the bigger Delco 24V alternators, it was a fairly easy switch, also eliminating the need for an external regulator. If I were you I would do the same on the HD16.

Eric is 100% right... Get rid of the generator and regulator problems and go with an alternator with internal regulator...
capacity wise, most of the generators in that era were 30 amps MAX... Unless you have a bunch of headlights on the tractor, 30 is fine... If you go with an alternator it might be 30 -35 or 60 amps... all are OK.

Something like this... you have to figure out the mount and pulley / adjustment is the biggest deal..... Make sure the SPEC says "IR" Internal Regulator... Some dont..

If the old generator has two 'mounting ears' at the bottom you may want to look over which make and model of a 24V Alt. would be the easier to adapt. There is one on Amazon that fits older A-C and Fiat-Allis machines, very reasonably priced as well. My picture posting skill failed me today or I would have put it on here

Here in Oz a common replacement is a Bosch 24 volt internal regulator. 55 amp I think. You can buy it with a mounting bracket.
I had no problem lining the belt pulley up with that mount welded to the generator bracket on an AC Forty Five grader. That was about 12 years ago so I don't remember if I had to change the belt length.
The Delco generator pulley fitted the shaft of the Bosch so the bigger section belt of the AC wasn't an issue. The Bosch doesn't use a Woodruff key so some Loctite was needed to keep it on.
