Hydraulic Pump

[gloved1]

Hi Tractor people,

Can anyone please verify for me that a hydraulic Pump from a Super Major would be the same as from a New performance Super major. I am slowly working me way back towards the pump being the issue with my Hydraulic Fault finding and have sourced a replacement but it is for a Super major as opposed to N.P Super Major.

Thanks

Its the same pump, that pump could be used in all tractors from 1952 to 1964 but needs a small right-angle elbow for the earlier tractors.

Further to Brian's post and to perhaps clarify the situation, the pumps are indeed,as he says, the same. If you are frowning and thinking "but I thought they were different". It is the gearing that was changed from Super Major to New Performance Super Major. So if you obtained a hydraulic pump from one (attached to its driven gear) it would not "fit" the other, without swopping driven gears.

The change occurred (according to my book) at 08C960337. The driving gear on the PTO shaft went from 33 teeth Super Major to 34 teeth with the New Performance Super Major. The driven gear on the pump went from 21 teeth (Super Major) to 18 teeth on a New Performance Super Major pump. I hope that is right Brian?

Thank you for that clarification Brian and Timee. I assume the mixed messages I was receiving was in reference to the driven gear.
