MAN — Inspection of the Belts

Routine Preventive Maintenance 4. If the engine is to be out of service for more than 30 days, remove the batteries and store in a cool, dry place. Keep batteries fully charged. Have any batteries that fail to hold a charge replaced. 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.
