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.
Timing Chain Removal/Installation
WARNING:
A hot engine can cause severe burns. Turn off the engine and wait until it
is cool before servicing.
CAUTION:
If the camshaft is rotated with the timing chain removed ...

A/C Compressor
Purpose
The A/C compressor circulates the refrigerant in the refrigerant cycle.
The A/C compressor compresses the gaseous refrigerant atomized by the evaporator,
and by pressurizing the gaseous refrigerant, liquification by the condenser
is facilitated.

Turbine/Input Shaft Speed Sensor, Output Shaft Speed Sensor [Fw6 A EL, Fw6 Ax
EL]
Purpose/Function
The turbine/input shaft speed sensor detects the rotation speed of the input
shaft (low clutch drum).
The output shaft speed sensor detects the rotation speed of the output shaft
(primary gear).
The turbine/input shaft speed sensor and output shaft speed ...
