1.	Which of the following when decreased reduces the bearing clearance?(a) Number of shims(b) Number of valves(c) Displacement of the piston(d) Number of spark plugsThis question was posed to me in class test.Asked question is from Valve Timing Technologies topic in section Valve Timing Technologies of Automotive Engine Design
Answer» The CORRECT answer is (a) Number of SHIMS For explanation I would say: SEVERAL shims are present on each side of the bearing, within it and the cap are also provided in the cast type for adjustment of CLEARANCE. Taking out several shims LEADS to a reduction in the bearing clearance.
