Inspection of the Belts
Inspection of the Belts
Detroit™ Gen 5 Heavy Duty engines utilize a specially designed belt material
which is exclusive to the Original Equipment Manufacturer (OEM). Replacement
with an aftermarket part may lead to shortened maintenance intervals and excessive
noise. Consult with an authorized Detroit™ service outlet to obtain proper engine
belts.
Belts will track slightly forward on the non-grooved pulleys when the engine is
running. Once the engine is turned off, the belt will re-center itself. Do not use any
type of cleaning solvent on the rubber parts of the tensioner or on belts. Detroit
does not approve the use of belt dressing or other like products as this may result in
premature belt wear. The belts should be replaced as recommended in the
maintenance tables using the appropriate engine duty cycle, Refer to section
"Preventive Maintenance Tables".
Inspect as follows:
1. Check the maintenance records to be sure the belts are not overdue for a
maintenance interval, Refer to section "Preventive Maintenance Tables".
Have the belts replaced if necessary.
2. Inspect the belt contact surfaces for chips, flaking, cracks, and discoloration
using the guidelines listed below. If any damage is noted, have both belts
replaced.
