1961 RPO 582 Fuel Injection Generator Bracket

[Richard M.]

I'm making a parts buck of the 315HP FI engine with it's 1102268 generator and 3711685 reproduction 4" pulley with NO offset.

The AIM shows the 3768152 generator bracket, with a note that the offset holes should face DOWNWARD, yet the picture shows them UPWARD

Which is correct?

Here is what I have installed, and it appears to be alright with the offset holes UPWARD, as pictured in the AIM.

I have a slight alignment issue with the assembly. Generator is rearward about 1/8". My HB and WP pulleys are properly aligned, yet the generator is rearward. Since the generator has solid mounts, there isn't much room for adjustment. This reproduction 3768152 generator bracket measures to spec, 1 5/8"H x 7 1/8"OAL. I'm unsure why the non FI generator (1102043) uses a offset 3 5/8" pulley, and this generator application has no offset pulley. It seems that a offset 4" pulley would align better.

Any ideas? (never mind).....

edit...I fixed it. I had to loosen the manifold and bring it forward, then loosened the generator brackets and moved them forward. i got just enough from everything to get a perfect alignment.

Richard,

They key is proper alignment and what gets you there, as you've found with the alignment of the fan belt, which is going to be important at higher speeds so as to not throw off the belt and also for wear in general. Same for the bracket. I'd assume that engineering meant what was written and that the drawing is just an artist's conception. But, unless there is some interference with the bracket one way or the other, I'd do what gives the best overall alignment.

Bob, Thanks.

Someone pointed me to a photo in Noland's C1 book, page 375, of a Parts Buck RPO 582 315hp engine, and it has shows offset holes... Upward, just like the AIM. When I built my parts buck for trial fitting, I set the generator bracket with the offset hole Upward, before I saw the references, thinking it'd give the generator the ability to tilt further inward, away from the manifold brace. This seemed to make it easier to attach the drive belt too.

Here you can see the offset direction, magnified with a eyeloop.

It also shows the manifold brace for the generator U-bracket quite clearly, unlike the AIM.

However, they say to leave the U-bracket loose to ease belt installation. I simply removed the adjusting brace, slipped the belt on, then moved the brace back in position and attached the bolt to the generator and it tightened fine.

While doing this trial fitting, I decided to write a document outlining some of my experiences when trying to get proper drive belt alignment on these engines.....attached below. It starts off trial fitting a 1102043 tach drive generator, then the 1102268 FI generator.
Special Thanks to fellow member Dave Zuberer for his help to document my information. He created and annotated a html file to a pdf for me. I may make changes and additions to it in the future. I'd like to add a Addendum regarding Harmonic Balancer and Pulley differences at a later time. If & when I do that, I will update here.

Rich -

After downloading that file, Adobe won't open it - it says the file is corrupted.

Re: 1961 RPO 582 Fuel Injection Generator Bracket

Strange, I just downloaded from the above link I uploaded and it loaded properly. I'm running an older version of Adobe though. 8.8.1

Can you check your version, while i update mine and I'll see if it has problems.

This is the one Dave sent me the other day. I'll drop him a line and see what he's using too.

I just upgraded to the latest 10.1.4 and it loaded fine John. Not sure why you're having errors. I'll email the file to you directly to see if that copy will work without errors.

Rich -

The file you e-mailed opened right up with v11.0.09 - don't know why the file I downloaded from here didn't. Must be aliens.

Richard,
Thank you for this excellent amount of information on the C1 pulley installations. If any of you out there are working or thinking about working on your generator /pulley alignment issue this PDF file is priceless. This is where the NCRS Technical Discussion Forum is such a great wealth of information. Thanks for sharing this with all of the C1 guys.

Wayne,

Glad it may help, and thanks for the nice comments. It does take some time to plan and photograph and write this stuff up, and I always like to learn and share whenever I can. Ever since I joined in the 80's, back then I always looked forward to the Restorer and all of the restoration articles. The authors of those articles were then, and still are, my heroes. Back in '86 I finally bought my dreamcar.... my '59. I was so infatuated with learning about it and those guys and their "knowledge on paper" helped me so much. Now that I have a few years experience with my own car and restorations I've performed over time, I like to put it down in the 'puter and pass it around. And also I must say a special thanks to fellow member Dave Zuberer for converting the html's to pdf's for distribution and enhancing my write-ups with his diagrams and notes. He makes them so much better looking. Thanks Dave!

Also, our TDB software has had many upgrades to allow more photos and larger file upload capability too. That makes it much easier to share as well. Special thanks to the developers for giving us the tools to do this kind of sharing and technical mind-melting.

Please see this new thread in the link below with a more appropriate Title with the latest updated PDF file of the above document. I cannot edit the earlier post to update the attachment due to Forum editing restrictions.

Re: 1961 RPO 582 Fuel Injection Generator Bracket

Last night I finally finished the rebuild/restore of this 2268 generator from a looooong time ago..

I used new NTN (Made in Canada) sealed bearings, new brushes, new hardware and a complete clean and refresh of the case to bare metal. Tested the field coils(~7 static ohms) and cleaned the armature commutator on my lathe, then tested with my growler and all good.

I first used semi-gloss on the case and gloss on the end-frames but it didn't look right, so I redid it all with low-gloss on the case and semi-gloss end-frames. To me it looks better. Delco tag mocked up with screws for now but will get rivets later. I had 2 generators and made one good one from the parts using cast iron endframes.

I'm going to to a "motor-the-generator" test using a ammeter to check spec and may do a quick tutorial with a video.

How to connect the battery and Motoring the generator. Meters were used to test voltage and Motor Test draw current.

Left meter is current. Right meter is voltage.

My 1961 shop manual lists max current in this test at 4.8 to 5.5 A. My reading of 7.6A at 12.4V is higher than spec.

After usage I'd expect this to be reduced. The new bearings are of the sealed type and much more stiff than the unsealed original oil-fed type.
