ABSTRACT:
A pre-assembled unit 10 for use in assembly of an engine valve system 150 in an engine 152. The pre-assembled unit 10 includes a spring 14 for providing a force for urging an engine valve 156 in a first direction, a spring seat 20 engaged with the spring 14, a spring retainer 78 for maintaining the spring 14 in a concentric position around the valve 156, and locks 82 for lockingly engaging the spring retainer 78 and the valve 156. The spring retainer 78 and the locks 82 transmit the spring force to the valve 156. The pre-assembled unit 10 includes a retention member 120 for temporarily maintaining the spring 14, the spring seat 20 and the spring retainer 78 together prior to installation into the engine valve system 150. The retention member 120 cooperates at its upper section 130 with the locks 82 and at its lower section 124 with an oil seal 22 on the spring seat 20 to hold the spring retainer 78 and the spring seat 20 in engagement with the spring 14. The retention member 120 is removable from the pre-assembled unit 10 upon relative movement of the valve 152 and the pre-assembled unit 10 during assembly of the engine valve system 150 in the engine 152.
