An improved pin housing sub-assembly configured for reliable assembly and stability as an intermediate sub-assembly. The length of the plunger return spring is greater than the diameter of the spring well in the pin housing, such that the spring cannot be accidentally installed sideways in the well. During assembly, the non-compressed longer spring places the pushrod seat flush with the end of the pin housing. A shallow annular groove is provided in the inner wall of the pin housing near the outer end thereof, and an expansion ring may be installed therein when the plunger return spring is slightly compressed. The expansion ring holds the sub-assembly together as an intermediate but is displaced by the spring tower in a subsequent assembly step to become the locking ring between the pin housing and the spring tower, as in the prior art.
A pin housing sub-assembly for use in a valve deactivation hydraulic valve lifter, said pin housing sub-assembly comprising:
A method for assembling a valve deactivation hydraulic valve lifter comprising a pin housing sub-assembly that includes a pin housing, a plunger return spring, a plunger sub-assembly, a pushrod seat assembly, an expansion ring, a first groove formed in the pin housing, and a second annular groove formed in the pin housing and positioned between the first annular groove and an open end of the pin housing, said method comprising:
