Pic. 2.284. Placing a plastic gauge on each camshaft journal: 1 - plastic gauge
Clean the working surfaces of the camshaft journals and bearing caps. Lay the camshafts in the bed of the cylinder head. Place a piece of plastic gauge on each camshaft journal (pic. 2.284).
Install bearing caps. Tighten the cover bolts with a tightening torque of 16 Nm.
Pic. 2.285. Flattened plastic gauge
Measure the width of flattened plastic gauges at their widest point and determine the clearance (pic. 2.285).
The radial clearance in the camshaft bearings is shown below.
Standard:
- inlet - 0.035–0.072 mm;
- graduation - 0.025–0.062 mm.
Maximum allowable:
- intake - 0.10 mm;
- graduation - 0.09 mm.
If the clearance is greater than the maximum, replace the camshaft. Replace bearing caps and cylinder head if necessary.
