Yes...I was going to  mention to Cal...we started buying those books probably 20 years ago on ebay....they were cheap to almost free....we bought everything we could get our hands on if we thought we didn't have it.....brochures..flyers...service bulletins...parts ...service...Garwood..Caro...Baker.  People were cleaning there shelves and we filled ours up. It's all gone now..seems like...occasionally some will show up...and of course there's lots of the common stuff that's helpful...but sellers appear to be emotionally attached to it...probably not having a clue what it's for.  Don't know if I'll ever get it all sorted...but it's fun to look through it if I think It will help someone.

 Hector...not sure about the pump splines...looking at the book of the picture I posted...it appears the pump shaft is plain and keyed to match a splined insert (2) to the drive shaft yoke.  Looks like the splined insert might be 10 splines.....but we don't know if that's what he  has...can't tell by the pictures he has posted

Danny...I think Hector (GEMDOZER) was thinking he might have some parts that would help you...was interested in how many splines on the pump?   Can you get the yoke of the end of the pump and take pictures of the pump or those parts maybe?
  Here are pictures of an HD9 crankshaft pulley...it should be the same as yours....all the HD9s should have come to there dealers with no blades...so all of these were the same. 1 picture is straight on....one a little from the side hoping to show some depth...as per Cal...it covers the bolt that holds the pulley on.....and of course someone might have modified something in the last 60 years....that would of course void the warranty...LOL

I think you do have the setup Mel shows but it is behind the plate the broken part is attached to. From the side smack the broken u joint flange on both sides and that front plate should start to break free. Rust is holding it fast in place.

Danny....were getting close....I'm still curious about the end of the yoke that goes into the pump? Can you get that off...lets see how that looks...splines...straight shaft with keyway?  If we can see that then everyone knows what you need.  Hector (Gemdozer) said he might have some parts...and if not....I know Codger and I would concur with Cal that all of that could be fabricated up pretty easy.

You can see the grease fitting on the housing to grease the shaft going through that housing. Pull those six bolts and split the house off the pump.

If'n it were me, and looking at those splines, I'd replace the pump also as it's splines are also beaten upon. The original pump may have parts available and could be rebuilt; this is possibility also.
