Taper limit: 0.08mm (D1-D5, D2-D6)
Round limit: 0.05mm (D2-D1, D6-D5)
Piston pin outside diameter
Measure piston pin outside diameter. If out of specification, replace the piston pin.
Piston pin outside diameter: 13.996～14.000mm
Piston ring
1. Push the piston ring parallel with the piston into the specified measuring point of the cylinder (10mm
from conjunction surface).
2. Measure end gap by space gauge. If out of specification, replace the piston ring.
End gap (installed): Top ring 0.15～0.30mnm
2nd ring 0.30～0.50mm
Oil ring 0.2～0.7mm
3. Install piston ring to piston, and measure side clearance between piston ring and its slot by space
gauge. If out of specification, replace the piston ring.
Side clearance: Top ring 0.04～0.08mm
2nd ring 0.02～0.04mm
Oil ring 0～0.22mm
Crankshaft
1. Measure diameter of crankshaft main journal, crankpin diameter and crankpin width. If out of
specification, replace the crankshaft.
Diameter of crankshaft main journal 34.997~35.009 mm
Crankpin diameter 30.997~31.009 mm
Crankpin width 21.00~21.07mm
2. Measure crankshaft run out. If out of specification, replace.
Crankshaft run out limit: 0.05mm
Crankpin oil clearance
1. Put a piece of plastic space gauge on to the crankpin in parallel to the crankshaft.
