Terex TW85 - V-Belt

7 Maintenance and care
88 TW85
7.9.6 V-belt
Check or tension V-belts only when the
engine is turned off.
Risk of injury!
• Check the entire V-belt for damage (visual
inspection).
Replace damaged or worn V-belts
immediately.
Checking V-belt tension
We recommend the use of a belt
tensioner gauge in order to check the V-
belt tension. The tension check must be
carried out according to the
manufacturer’s manual.
When new V-belts are mounted, their
tension has to be checked after the first
15 min. of operation, and adjusted if
necessary.
Checking Tension Without Using a Belt
Tensioner Gauge
• To check the tension, press the V-belt with your
thumb in the middle of the greatest free length,
and measure the sag.
• Using medium thumb pressure of approx. 45 N,
the V-belt sag should equal approx. 10mm.
Tensioning V-belts – Coolant/Fuel Pump
• Slacken the fastening screws (71/1, x2) on the
control handle.
• Rotate the fuel pump (71/2) until the tension is
correct.
• Re-tighten the fastening screws (71/1) of the
control handle.
• Check the tension again.
Tensioning V-belts – Generator
• Slacken the fastening screws (71/3, x3) of the
generator (71/5).
• Adjust the generator using the screw (71/4) until
the V-belt tension is correct.
• Re-tighten the fastening screws (71/3).
