Mazda CX-5 Service & Repair Manual: Timing Chain, Chain Tensioner
Purpose, Function
Timing chain
-
The timing chain transmits the rotation force of the crankshaft to the camshaft to perform the rotation timing of the crankshaft and camshaft.
Chain tensioner
-
The chain tensioner constantly maintains the timing chain tension and the timing chain operation is stabilized.
Construction
Timing chain
-
The timing chain is installed between the camshaft sprocket and crankshaft sprocket.
-
Lubrication of the timing chain and each sprocket is performed using the engine oil from the engine front cover.
-
Improvement of the rigidity of the chain guide and tensioner arm and the stability of the timing chain operation have reduced the sliding resistance.
Chain tensioner
-
The chain tensioner is installed to the cylinder block (engine front).
-
An oil pressure type chain tensioner has been adopted for the chain tensioner.
OPERATION
Chain tensioner
-
Fluctuation in the timing chain tension by oil pressure and spring force is suppressed, and the tension is maintained at a constant.
