Replaced pump and have good hydraulics. But when operating the
tractor the hydraulics occasionally pulse - dragging on the motor.
sometimes it will pulse every ten seconds and it makes the engine
work. TIA
 
There is a pilot valve in the demand driven hydraulic. It is located in the hydraulic block on the right side (see parts diagram in caseih.com) this orifice can become partially blocked, and it also has a screen that plugs up. If it is .030" it might be drilled to .040" to reduce or eliminate the pulsing. Jim
