Section 04 ENGINE (2-STROKE) Subsection 04 (TOP END) All Engines except 947 DI – Remove both spark plugs and bring one piston to Top Dead Center a using a TDC gauge. F01D2IA 1. Bring piston to TDC 947 DI Engines – Remove both direct injectors and bring one piston to Top Dead Center using a TDC gauge. Keep spark plugs in their holes. All Engines – Obtain a graduated burette (capacity 0 - 50 cc) and fill with an equal part (50/50) of gasoline and injection oil. 1 F00B0BA 1 1. Graduated burette (0 - 50 cc) – Open burette valve to fill its tip. Add liquid in burette until level reaches 0 cc. – Inject the burette content through the spark plug hole on all engines except 947 DI and through direct injector hole on DI engines until liquid touches the top hole. F00D0HA 1 1. Top of spark plug hole NOTE: The liquid level in cylinder must not drop for a few seconds after filling. If so, there is a leak between piston and cylinder. The recorded volume would be false. – Let burette stand upward for about 10 minutes, until liquid level is stabilized. – Read the burette scale to obtain the quantity of liquid injected in the combustion chamber. 126 smr2004-Complete Line Up 28
Compare the obtained value with the table below. Thevolumeshouldbewithintheallowablerange. If the volume of the combustion chamber is not within specifications, change cylinder base gasket thickness as follow. A higher volume dictates a thinner gasket. A lower volume dictates a thicker gasket. All Engines except DI NOTE: When the combustion chamber is filled to top of spark plug hole, it includes an amount of 2.39 cc corresponding to the spark plug tip. The following table of combustion chamber volume includes this value. All Engines ENGINE COMBUSTION CHAMBER VOLUME 717 31.2 - 34.0 cc 787 RFI 34.7 - 37.9 cc 947 DI 45.7 - 48.4 cc – Repeat the procedure for the other cylinder(s).
