these inspections. An idler sprocket and chain
tightener are used on most engines to adjust chain
tension. During operation, chains increase slightly
in length because of stretch and wear. Ad-
justments should be made for these increases
whenever necessary.
When you are installing a new chain, peen the
connecting link pins into place, but avoid excessive
peening. After peening, make sure the links move
freely without binding in position. Cotter pins
must be secured or the joint pin ends riveted,

carried at all times. Always check engine timing
after installing a new timing and accessory drive
mechanism.
