Appreciate your help Aaron - you're certainly more experienced in understanding "Spanish-English" than I :thumbsup:
Uruguyao - I may be mistaken in believing Ford used a pump mounted at the timing case.
I'm thinking more and more the pump is driven off a gear at the end of the camshaft - it's certainly at the rear of the engine. This cannot be used on a 135. That being the case, a hydraulic pump which will match the mounting holes on the RH side of the timing case where a power steering pump normally is fitted would be the best option, if a suitable pump can be obtained. The gear which would drive it I believe is certainly capable of coping with the load - it is about 1" wide. Trucks have a small "PTO" drive off their gearbox for operating a hydraulic pump for a tilt-tray, dumper body and many other applications. These drive gears are sometimes as small as 5/8" wide.
But I'm also wondering what is the reason you need a larger hydraulic pump? What equipment would you use it to operate? And does it need to be permanently-mounted? I'm also thinking an additional pump driven by the PTO shaft might be an option?
Sorry for the confusion and all the questions.
