ABSTRACT:
An hydraulic tensioner using engine lubricating oil as its operating fluid is mountable on an engine block by a mounting plate serving both as a mounting adapter and as a closure for an oil reservoir opening in the tensioner housing. A gasket between the tensioner housing and the mounting plate prevents leakage of oil from the reservoir. To facilitate installation of the three-part assembly consisting of the tensioner, the mounting plate and the gasket, the three elements are temporarily secured together before mounting to enable the installer to handle the three elements easily with one hand. The temporary assembly of the three elements together also reduces the likelihood of damage to the gasket. Separate rivets, or bosses formed in the gasket, can be used to hold the elements together before mounting.
