Camshaft Removal and Reassembly

What is the first step in the process of removing and reassembling a single overhead camshaft?

• Clean the ‘Cylinder Head’ in the ‘Parts Washer’

• Loosen the camshaft bearing caps

• Inspect the bearing surfaces for wear or scratches

• Remove and clean the camshaft

How should the camshaft bearing caps be loosened?

• In any order

• In the order recommended by the manufacturer

• In reverse order of the tightening sequence

• All at once

Why is it important to note the position of the bearing caps?

• To ensure proper alignment of the camshaft

• To prevent oil leakage

• To identify the front of the engine

• To make the reassembly process easier

What should be done if the camshaft bearing caps are not numbered?

• Leave them as they are

• Mark them using a dot punch or ‘number’ punch

• Replace them with numbered caps

• Clean them thoroughly

What should be done after removing the camshaft?

• Inspect all bearing surfaces for wear or scratches

• Clean the ‘Cylinder Head’ in the ‘Parts Washer’

• Reassemble the camshaft to the cylinder head

• Tighten the nuts in several passes of the proper torque sequence

What should be done if the bearing surfaces of the camshaft show wear or scratches?

• Replace the camshaft or rebore bearing surfaces

• Reassemble the camshaft to the cylinder head

• Clean the ‘Cylinder Head’ in the ‘Parts Washer’

• Inspect the bearing surfaces of the cylinder head

How should the nuts be tightened when reassembling the camshaft?

• In any order

• In the order recommended by the manufacturer

• In reverse order of the tightening sequence

• All at once

What should be done after tightening each camshaft bearing cap?

• Check for oil leakage

• Check if the crankshaft can be rotated by hand

• Inspect the bearing surfaces for wear or scratches

• Apply more torque to the nuts

What should be done if the crankshaft cannot be rotated by hand after tightening a bearing cap?

• Remove the camshaft

• Check for oil leakage

• Remove the bearing cap and check for the source of the interference

• Apply more torque to the nuts

What should be done during the assembly of the camshaft?

• Oil the camshaft bearings with light engine oil

• Clean the ‘Cylinder Head’ in the ‘Parts Washer’

• Inspect the bearing surfaces for wear or scratches

• Tighten the nuts in several passes of the proper torque sequence
