The inner diameter of the sleeve is 5.510–5.530 mm.
Calculate by subtracting the valve stem diameter from the guide bushing inside diameter to obtain the standard backlash between the valve stem and guide.
Standard backlash value:
- inlet - 0.025–0.060 mm;
- release - 0.030–0.065 mm.
Maximum tolerance:
- inlet - 0.08 mm;
- outlet - 0.10 mm.
If the clearance is greater than the maximum, replace the valve and guide bushing.
