Am wondering if either an incorrect bracket was installed for this 292 or maybe, if it has been installed backwards or upside down, never paid much attention to it till now.
The photo has the same type of belt adjuster bracket as I have. The problem is that it runs out of adjustment or maxed out before the belt is tight enough using stock size belt.
The shop manual isn't too clear on this, and further muddys things by showing it installed two different ways. Currently installed pointing "down" with the slider and spacer at the generator itself.
Pretty sure can get a little more adjustment by flipping it up, and it would be a lot easier to adjust belt tension by having the slider portion attached to the block, too. Anybody have a diagram or some insight on this? Photo isn't clear, though not mine. Thanks!
How is the lower bracket installed, though? Is the sliding part attached to the block, or the generator? It can't be correct now because there is no room for adjustment, it's pegged all the way out and belt is too loose. Seems like about halfway or 3/4 along the slot would be typical for adjustment range in something like this.
edit: Looks like the F100 bracket is supposed to be straight - the one installed is curved or J shaped?
My bracket has about a 45 degree curve in it. The slot is on the generator side.
The adjusting bracket is attached to the middle bolt of the engine mount and points down.
Your parts look correct.
What is the diameter of your pulley? Mine is about 3 3/16 measuring across the face of the pulley, not the actual diameter of the groove. My belt is toward the end of the adjustment, but I don't know how old the belt is. When I bought the truck the tires looked new, but the date code indicated they were 14 years old.
I thought of that right away of course, tho stock belt "should" work. Just made me wonder what the deal was. Could be the fan pulley is a bit different diameter, parts gets replaced after 50 years. I did just replace the generator with one that has a slightly smaller diameter pulley, enough so the belt won't tighten anyway.
I bought a belt for my 66 with a 352 that the parts store indicated was the correct belt. It was about an inch to long so I had to use the make 3-4 trips to the parts store method to get a properly fitting belt.
Is it possible that you got a generator for a 223 I6? They look similar but the location/orientation of the ear on the generator where the slider bolts is a little different. I have a V8 generator on my 223 and had to use a different slider bracket to make it work.
Here's how mine is put together. Plenty of adjustment room, though a pain to adjust. (I think last time I used a 2x4 to put tension on the belt--a three handed job!)
I'll have to check but It passed the eyeball test side by side. It's a standard 12 volt Ford generator used for a long time. I have enough parts laying around to make a "good" generator but am really trying to avoid pulling that thing again. Flipping the bracket might get a little extra, going to try that. Failing that just go with a smaller belt. edit:
Hell, it just needs to run to a different bolt hole is all! I really need to get better lights in the garage, that's my story anyway.
Thanks ND! Works fine now plenty of belt adjustment when installed correctly.
The old generator armature had been turned down to about nothing. The brushes had hardly any wear. But couldn't get a decent charge rate for some reason, even after adjusting the repro script regulator.
Now it's charging a little high with the new generator, and a slightly smaller pulley might be part of that. Have a NOS Motorcraft regulator that will install next and should be about perfect.. We'll see.
edit: Works slick! even with headlights, heater running on high it tops out at high RPM @ 15.2 volts around 32F. Even seems to idle better bit that's probably my imagination.
