ABSTRACT:
This disclosure relates to improvements in hydraulic dashpot chain tensioners for the timing chains of motor vehicles. A kit for modifying existing chain tensioners is disclosed which can be readily connected to a chain tensioner to eliminate leakage of air into the dashpot. The kit comprises an open, cup-like oil reservoir adapted to be sealingly secured to the chain tensioner in fluid communication with the dashpot. Baffles are arranged adjacent the open end of the cup member to prevent loss of oil therefrom by reason of centrifugal forces acting on the oil.
