OM 4080
INTRODUCTION
This master timing tool kit speci cally compiles to give a comprehensive range of the engine timing locking tool for
the cam belt, the chain and the gear.
For Honda, Mazda, Daewoo, Hyundai, Subaru
Important kit is for working on the motor, e.g. the timing belt, the general motor setting, and the camshaft.
MODE D'EMPLOI
1. Valve Timing
Valve timing is essential to the ef cient performance of the Petrol or Diesel engine.
The valves are opened and closed by the camshaft(s) which are driven by the cam belt, chain or gears
from the crankshaft.
2. Crankshaft Locking Tools
The Crankshaft TDC Location Pin is designed to screw into the cylinder block and to provide a stop for the
crankshaft to be positioned against to set the TDC position.
Turn the engine in the normal direction of rotation until the timing mark on the injection pump sprocket lines up with
the cast lug on the timing cover.
Remove the plug from the cylinder block access hole and screw in the TDC location pin.
Slowly turn the crankshaft clockwise until the web makes contact with the end of the pin. Number 1 cylinder is now
set at TDC on ignition stroke
3. Camshaft Setting/Locking Tools
Camshaft setting/locking tools are used to accurately align a datum slot, located in the end of the camshaft, with
the top face of the camshaft housing to hold the camshaft at the TDC position.
Follow the service manual instructions to remove the camshaft cover and timing chain covers.
Turn engine in the normal direction of rotation until the camshaft setting/locking plate can be inserted into the
machined slot in the end of the camshaft.
When tting Camshaft setting/locking plates, feeler gauges/ shims of equal thickness can be inserted under either
side of the plate until all free play has been eliminated. The camshaft is now locked in its timing position and service
work can now be carried out.
4. Tensioning Tools
The tension of the chain is vitally important and must be set using the tensioner. If an automatic tensioner is tted it
should not be tampered with.
Manually tensioned chains must be tensioner to the manufacturer's speci cations.
