3.3 V-Belt and Clutch
3.3.1 Checking the V-Belt
Aer 200 hours of operation, remove the upper belt cover
to check the V-belt tension (Figure 2). Tension is best if
the belt bends about 0.4 in when depressed firmly with
finger between shas. Loose or worn V-belts reduce power
transmission eiciency, causing weak compaction, reducing
the life of the belt itself.
NEVER attempt to check the V-belt while the engine is running. Severe
injury can occur if your hand is caught between the V-belt and the clutch.
Always use safety gloves, while the engine is o.
3.3.2 Replacing the V-Belt
Remove the belt covers. Use an oset wrench (13mm) or the like on the vibrator pulley
(lower) fastening bolt. Utilize a waste cloth or the like at midway of V-belt on the le side
and while pulling it back strongly, rotate the oset wrench clockwise so that the V-belt is
removed.
3.3.3 Checking the Clutch
Check the clutch simultaneously with V-belt. With the belt removed, check the outer
drum of the clutch for seizure and “V” groove for wear or damage. Clean the “V” groove
as necessary. Wear of the lining or shoe should be checked with running check. If the
shoe is worn, power transmission becomes deficient and slipping will result.
Whenever the compactor’s vibration becomes weak during normal
operation (regardless of operation hours), check the V-belt and clutch
immediately.
