Belts for Truckmount Maintenance


A frequently overlooked item is the belts. It’s easy to just think that simply if they look good and if they’re not causing issues then there’s nothing to worry about. But, often times they can be misleading by appearance and break without warning. Many manuals suggest replacing at certain intervals and re-tensioning in between since they do stretch once in use. This can be very important in the case of machines that don’t utilize a tensioner pulley such as a 370ss Since they are directly attached to the shaft of the engine, all of the torque gets absorbed by the belts. This stretches them fairly quickly and must be re-tensioned every 100 hours in the case of the 370ss. Regardless of the configuration it is wise to follow the maintenance interval chart to avoid an emergency repair.
