D17 Live Hydraulics project

   JK, sorry- I went back and checked my posting... dunno why I posted 2.6gpm, SHOULD be 2.6 CUBIC INCHES per Revolution.  At 1800rpm, that comes out to 20gpm.

I WOULD have gone with a vane-pump, but I frequently idle the D17 way down to 'creep' it carefully into position.  My Clark IT-60 HAD a vane-pump (and closed-center hydraulics) and regularly shelled out (and seized up) vane pumps, but worst of all, when it was idled-down, it went so slow that the vanes would retract, and there'd be no lift or tilt, no steering (yikes!) and general uselessness of the machine at low speed.

My general expectation is, that no matter WHAT I run, I don't think I'll ever run an implement that needs more than 20gpm at 2000psi... and it'd probably be a ditch-mower (flail, etc) or something similar.  To get that, I'll be at max goverened speed.  When using a log-splitter, or the backhoe unit, I don't think I'll need more than 5-6gpm, so burbling along at 650rpm will be just fine.

	And Sensei- I looked at the Steiner ref, and it's cool that they have a coupler listed... I found it curious, however, that it didn't list it as fitting the Allis tractors... seein's how it does, in fact, bolt up. Then I looked closer... Your coupler is listed as being a 1" x 20 spline shaft, which is a common standard size for SAE2 and SAE3 hydraulic pumps. I used a less-common standard 7/8 x 13 spline shaft, because it will fit down the center of the stock bolster crank-hole. A 1" shaft won't fit my Series 1 bolster... if I remember correctly, the bolster hole was just big enough for the 7/8" shaft to fit and engage the coupler, and leave mebbie 0.060" 'play' before striking the bolster bore, and a 1" was too big to allow a proper lineup. I sure hope it'll fit yours... Edited by DaveKamp - 28 Nov 2011 at 9:39am

	Hi Dave, I have the project finished, the adapter I bought is for a 1" 10 spline not a 20 spline. The Max shaft OD at the adapter (splines) is 1.0". The adapter bolted right up to the pully. The shaft area where it goes through the bolster is 0.8 inches. The ID clear on my D17 series 1 is 1.30". It fit through with no issues of alignment at all and I can remove it with no problems!

	Hi SC! Cool that it all fits! if it's clearing okay, then power to 'ya!!! I"m wondering why Steiner has it listed, but doesn't include the compatibility to AC...??? Between a barrage of business road-assignments, I've been working on my snowblade installation, so haven't made much progress on my live hydraulic setup... but I'll get back to it in a bit. Eventually, my snowblade (a 7.5' Meyer) will lose it's electric hoist/swing system, and get quick-connectors and a lift ram for using the live hydraulic system, but for now it'll be using a battery. Stay tuned!

	I have a Farmall 504 diesel of 1962 vintage. Early 2nd year. It has a crank pulley that also has hand crank finger bosses. It also has a hole for a crank in the bolster! Who hand cranks a diesel? I feel they were using up old parts at the time! CT

	To make modernizing your tractor easier, we offer these front mounting kits for purchase. No machining required. Make sure your front pulley has provision to bolt adapter hub! Tractors earlier than: D14 engine serial #149-11562/ tractor serial #11476 and D17 gas tractor serial #15931/diesel tractor engine #104840 DID NOT leave the factory with the front pulley that has the 4-bolt pattern for adapter hub.
