I dont know how to multi quote on here.
Would it work to pull the pto unit off my dads CA to borrow? He does not have any belt powered implements. Only a small 3 point point bush hog. Would the center pto splines be the same from my early B to his CA? |

If your dad has a 3 point hitch, then it runs off his hydraulic pump which is part of the PTO unit/ housing.... The pumps do not interchange between the CA and the B... so i assume the HOUSINGS are different and the pump drive internal is different

your best bet is to got to WOODS and buy a pulley for the original B shaft, or buy a pulley with a 1 inch bore and have someone machine the taper to the smaller shaft.
maybe call these guys and talk about the "old style " pulley. https://store.germanbliss.com/woods-l59ac-b-1-allis-chalmers-b-undermount-mid-mount-rotary-cutter-mounting-frame-assembly-parts Edited by steve(ill) - 21 Oct 2020 at 1:11pm |

I called them and they didnt know what I was talking about.
I ended up finding a pto unit at a local tractor salvage it even has the hydraulic pump. I put it on yesterday and it works. Now I can mow. Not sure how the hydraulics work right now it is open but not pumping fluid. It has a thing that turns two ways I figured it is for kicking it on or off. Right now it is not spitting fluid out so it must be in the off position. I will put a bucket under it and rotate it the other way and see what happens. For now I will leave it in the position that its not pumping and put a plug on it. I just dont want to run it dry or hydro lock it. |

there should be a rod about 8 inches long pointing straight forward under the seat... You pull that UP and it engages the PTO shaft and drives the hydraulic pump.. The pump just circulates oil until you move the SECOND lever.
I dont see it in your photo, but on the side of the pump / valve there are two round discs, one on top of the other, about 2 inches in diameter.. The ENGAGE rod hooks into the inner round plate and rotates it... In the center position is HOLD... rotate one way and you get OIL OUT of the pump... rotate the other way and you get FLOAT DOWN ( oil returns from the hose/ cylinder back into the pump cavity....... the round disc should be spring loaded and set in the CENTER position if everything is loose.. It may be rusted and need to be sprayed with WD40 ... or it may need disassemble and cleaned internal.

the photo below is an exploded view of the B hydraulic pump / valve... the two discs you are playing with are #34 and #33... spring #14 allows them to move seperate of each other.. The ROD #7 moves plate #33 and as it rotates it grabs #34 and rotates it also.. They must move freely and not stick to each other..... Items #24 are the PISTONS.. it is a piston pump... the "valve" portion is all the parts on the top of the photo. If it has been dry or dirty oil put thru the valve, you can have sticking of the spools.. Externally you can get rust / sticking / binding of the plates.

The valve bolts on with 4 bolts/ studs... One option if you are not using the pump is to remove it and bolt a 1/8 inch thick plate over the hole to cover it and keep the oil inside... then you can play with the pump on the bench........... get the manual if you are disassembling the pump.

Right on. Yeah It had those plates and I can move them Separately by hand.I will probably pull it off and make a plate until I find a reason to have hydraulics on it. I will need to pull this thing all apart someday before I paint the tractor to put new seals in anyways.

this is GREAT! I can finally help someone! i am going thru this right now. I got a used WOOODS L59 mower and the white pully will not fit my shaft. if you read closely the WOODS manuel addresses it and says you need to get a newer PTO with the bigger shaft. the way i understand is the rear and side shaft were small, then the side shaft got bigger and finally the rear (PTO) shaft was bigger also. there is also shafts with the lobes to run hysdraulics. i took another pto to SANDY LAKE IMPLEMENT to get the PTO box checked out before installation. Im currently waiting till i can get tractor outta shed to install mower. probably will not get belt and stuff installed till spring.

The pulley was available at one time for the small shaft .Because. My customer got back to again this week and is selling his B now, so if he gets it sold , I will be getting the pulley (for small shaft ) that I got from Woods a few years ago for him. When I do I will post it in Classified .

nonetheless ,still dead. If all else fails ,Read all that is PRINTED. Just because you do not have the tools for job , it dose not make it a bad design. |

JC... the original B came with a 6 spline PTO rear shaft of 1- 1/8 inch diameter.... They later changed to 1- 3/8 inch diameter which is a "standard" for a lot of older tractors... You can buy an adapter sleeve to put over the smaller shaft if needed... Of course the larger 1-3/8 inch shaft in the new housing would be a better idea.

Looks like Fred will eventually have the remedy you need to take care of that issue. To me, that would be the easiest thing to do. No pullin' yer' hair out. Purchase the smaller diameter shaft pulley and its a done deal....
