Mazda Bongo V6 Hydraulic Cam Belt Tensioner – This is an after-market copy of the cam/timing belt hydraulic tensioner for the V6 petrol Bongo. It has been sourced from USA; the genuine Mazda ones from Japan are ferociously expensive!
Typically, hydraulic tensioners can operate with a larger range of dynamic belt lengths than mechanical tensioners. Due to the length of stroke of the actuator and the lever design the hydraulic tensioner system is particularly suitable for large V6 or V8 applications.
2.5 Litre V6 Petrol – (J5) – Chassis (SG5W).
It is part number 12-770 at the bottom of this diagram.
