How to Select Piston and Bearing EBS00KNV
DESCRIPTION
*For the service parts, the grade for fitting cannot be selected between a piston pin and a connecting rod.
(Only 0 grade is available.) The information at the shipment from the plant is described as a reference.
●The identification grade stamped on each part is the grade for the dimension measured in new condition.
This grade cannot apply to reused parts.
●For reused or repaired parts, measure the dimension accurately. Determine the grade by comparing the
measurement with the values of each selection table.
●For details of the measurement method of each part, the reuse standards and the selection method of the
selective fitting parts, refer to the text.

18. Loosen and remove the installation bolts in rear cam sprocket.
●Loosen rear cam sprocket installation bolts by fixing the hexagonal portion of the camshaft.
19. Remove vacuum pump and cylinder head rear cover assembly.
●Remove and install vacuum pump, sprocket, drive chain and
chain guide as an assembly.
●Loosen mounting bolts in reverse order shown in figure.
●Do not remove any bolts not shown in figure. (Especially
never remove M6 bolts on vacuum pump.)
●Use seal cutter (special service tool) or other suitable tool to
remove.
INSTALLATION
1. Install vacuum pump and cylinder head rear cover assembly
onto cylinder head. Refer to EM-142, "
ASSEMBLY" .
●Apply Genuine Liquid Gasket or equivalent (Refer to EM-111,
"Precautions For Liquid Gasket" .) to area shown in the figure.
●Attaching should be done with in 5 minutes after coating.
2. Tighten mounting bolts in order shown in the figure.
3. Install rear cam sprocket mounting bolts by fixing the hexagonal

●Attaching should be done with in 5 minutes after coating.
CAUTION:
Never start engine with vacuum circuit being open. If
engine is started and vehicle is running while vacuum
pump is open (with vacuum hose disconnected), blow-by
flow rate will increase and engine may be damaged.
6. Install in reverse order of removal after this step.
●When vacuum hose is connected, insert it securely by at least
