Camshaft runout
1. Place the Y-blocks on a perfectly flat table and place the camshaft on them with journals No.2 and 4.
Attention. Do not interfere with the camshaft support with the journal Na1 (from the camshaft toothed pulley side), since its diameter differs from the diameters of the other four necks.
2. Install the dial indicator (A) vertically on neck No.3.
3. Turn the camshaft by hand one revolution and measure the camshaft runout with a dial indicator (indicator reading from one extreme position to the other).
4. If the measured value exceeds the maximum permissible value (see section "Service data and specification" at the end of the chapter), replace the camshaft with a new one.
Camshaft cam height
1. Use a micrometer (A) to measure the cam height.
2. If the measured value exceeds the maximum permissible value (see section "Service data and specification" at the end of the chapter), replace the camshaft with a new one.
Axial play of the camshaft
1. Install the camshaft.
2. Install the camshaft covers.
3. Using a dial indicator, measure the axial play of the camshaft (see section "Service data and specification" at the end of the chapter).
Valve lifters
1. Measure the outside diameter of the valve tappet (see section "Service data and specification" at the end of the chapter).
2. Measure the inner diameter of the valve tappet hole in the cylinder head (see section "Service data and specification" at the end of the chapter), (www.monolith.in.ua)
3. Calculate the valve tappet clearance:
(Valve tappet clearance) = (Valve tappet bore inner diameter) - (Valve tappet diameter)
Compare the obtained value with the standard one (see section "Service data and specification" at the end of the chapter).
