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.

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.

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.

Welded to the bolt? Maybe try unsrcewing it. Didn't think 'B's were that early.

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...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 |

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

Thanks for explaining farther Codger. I just wanted to make sure the problem did not get bigger.
Mel you have it, but even more you found it and got pictures over her too.

Mel to the rescue. Those are the books that are indispensable because unlike the tractor books, most can not be found online @ minnpar, and who knows how longs those will last.

Ok.....Man you guys are making me work hard here!!!...Dug through our archives and library and did find this Garwood book. They did make a hydraulic blade set up for all the dozers at the time. Cal's right that the cable blades and units seem to be more popular then. Also as he says...the HYDRECO pump was the main player then.....the pump in your picture I'm sure is a HYDRECO. I'm also sure the whole hardnose assembly is Garwood with maybe some modifications. The parts book of course does not mention HYDRECO by name. If I get them posted right the last picture....albeit disappointing...does not show getting the yoke of the pulley. I'll look at a HD 9 tractor tomorrow that might give us some help. Don't break anything ....cause yes..you should be able to build one. |

I can see that happening with a nodular iron crankshaft of a Ford 460 engine. I've seen the crank snout snapped off on those engines from using belt driven hydraulic clutch pumps. High engine rpm and the all or nothing engagement these offer is brutal via shock loading.
One shouldn't need to hit this very hard at all. The trick is to set up high frequency vibrations through the parts with mechanical leverage in your favor. An air hammer does a great job for this. It is possible that front yoke is bolted to the front plate on the backside also. This plate and yoke assembly is then bolted to the sheave. If so, and with the four capscrews removed as shown, side force via hammer to the remaining yoke ear would break it loose.

My experience of someone hammering on a crank shafted ended very badly. Was a Ford 460 in a New Holland bale wagon if a gas engine may have a weaker crank. But the pully needed to come of crank to replace hydraulic drive belts. It had places to use pusher bolts but threads where stripped owner elected to use chisels as a wedge as suggested here. It came off and new belts installed. A mile down the road the crank broke. And that is a literal mile ran 10 minutes at most. As a interesting fact the bale wagon owner also had 4 or 5 HD 9 crawlers for tillage.
