W9 Loader on D15II

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I have a D15II SC tractor that I picked up very reasonbly and it came with a rebuilt motor. I want to put a loader on it and picked up a W9 loader for nearly nothing; still has the original material tines and even has the original jay hooks for the rear mounts. Loader has pipe frame and square tube loader; the mounting tabs for the trip handle have never even been welded and all other original Freeman welds are very good. Plan is to build proper full brackets for suitable side mounts, plus extending brackets rearward for full mounting to the rear axles. 

Instead of mounting the crankshaft driven pump, adding a vertical resevoir and brackets for seperate valve block (controls), I am looking at mounting a V&M "add a valve" so I can use the tilt cylinder I need for the bale spear that will be mounted in-place of the original manual bucket. Loader portion framework is solid and mounting a smaller cylinder for the tilt action is not a problem.
Question is, will the tractor hydraulic resevoir supply enough fluid for the small tilt cylinder, in addition to the one way lift cylinders on the loader; will this damage the pre-set on the internal pump? Will volume be an issue when loader is lowered to the ground and small cylinder for tilt is also retracted?
Tractor has already been rewired with a 12v neg. ground alternator, so solenoid of "add a valve" should not be an issue.
Rear lift arms will not be needed as this tractor will be for loader use only.
Thoughts are welcome as I will be mounting this loader for full hyd use, just wanting to get around additional resevoir/operating valve bank as stated.
Thanks

	Web site for V&M "Add-A-Valve" is www.vandminc.com, for those that want to check these out. Would be interested in any feedback anyone has on past use with newer or older tractors. Thanks

	Tim You may want to look into the 12V self contained hydraulic pump/tank/electric valve setups that are used for tail gate and dump trailer lifts. I have a single acting one on my tilt bed carhauler trailer and a doulbe acting one I hung off the side of my D14 for the hydraulic chute director. Both have a large enough resevoir to run a fairly big cylinder. They sure do eliminate a lot of plumbing and do the job well.

	Your tractor has the high pressure/low volume hydraulic pump. So it only pumps 1.5 gpm. I don't think it would supply enough oil to both the lift arms and hydraulic bucket. If it did, it would function VERY slowly.

	Thanks guys, point well taken and this is why this forum is so handy as reminders like gpm detail get pushed to the side sometimes; at least for me. Speed of operation is not really an issue for me, but DSeries4 brings up a good point. Greg's idea is something else I have considered and may be the best all around choice to allow 12v pump running of the smaller two-way cylinder for tilt, while leaving the one-way rams plumbed directly to the single service outlet and using the lift/lower on the quadrant. I have no real need for replacing the single acting cylinders anyway as the original loader frame cylinder mounts are not heavy enough to deal with those return stresses; if I had two-way, I would be tempted to use them and break something ........ Thanks
