Belt Drive

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.

Drive belts wear differently based on environmental conditions and vehicle duty cycle. If the vehicle is operated in extremely hot or cold climates, or is exposed to significant dust/debris/road salt, the lifetime of the belts may be significantly reduced. The belts should be replaced per the maintenance intervals, Preventive Maintenance Tables.
