Title
(EN) RETENTION OF HYDRAULIC LASH ADJUSTER IN ROCKER LEVER ASSEMBLY
(FR) RETENUE DE RATTRAPEUR DE JEU HYDRAULIQUE DANS UN ENSEMBLE LEVIER OSCILLANT
Abstract
(EN)
A rocker lever sub-assembly for use with a hydraulic lash adjuster including a rocker lever arm having a bore wall that surrounds a first bore configured to receive at least part of the hydraulic lash adjuster therein, the bore wall having a second bore that intersects the first bore, and a retention device for insertion into the first and second bores to retain the hydraulic lash adjuster assembled with the first bore. The bore wall defines a retention bore at the intersection of the first and second bores. The second bore is positioned along the bore wall to position the retention device in the annular groove of the hydraulic lash adjuster such that the hydraulic lash adjuster can actuate about the retention device. The retention device can be removed from the second bore to disassemble the hydraulic lash adjuster from the first bore.
(FR)
Un sous-ensemble de levier oscillant destiné à être utilisé avec un rattrapeur de jeu hydraulique comprend un bras de levier oscillant ayant une paroi d'alésage qui entoure un premier alésage configuré pour recevoir au moins une partie du rattrapeur de jeu hydraulique à l'intérieur de celui-ci, la paroi d'alésage ayant un second alésage qui coupe le premier alésage, et un dispositif de retenue destiné à être inséré dans les premier et second alésages pour retenir le rattrapeur de jeu hydraulique assemblé avec le premier alésage. La paroi d'alésage définit un alésage de retenue à l'intersection des premier et second alésages. Le second alésage est positionné le long de la paroi d'alésage pour positionner le dispositif de retenue dans la rainure annulaire du rattrapeur de jeu hydraulique de telle sorte que le rattrapeur de jeu hydraulique peut actionner le dispositif de retenue. Le dispositif de retenue peut être retiré du second alésage pour désassembler le rattrapeur de jeu hydraulique du premier alésage.
