Product Overview
Belt squeal, visible belt flutter, repeated belt loss, a crooked running belt, or rough pulley bearings can point to a worn tensioner. An incorrect belt, misaligned pump, damaged bracket, oil contamination, or another seized accessory can quickly damage a new assembly.
The spring-loaded assembly maintains drive-belt tension and guides the belt as engine speed and load change. It is not the cooling-fan idler sold under other Bobcat references, so compare the mounted location and complete casting.
Match 6735884, pulley diameter and width, arm and spring layout, mounting pattern, belt path, loader model, serial break, and product photos. Some listings combine this tensioner with separate pulleys that are not included here.

Frequently Asked Questions
Q: Can a bad tensioner make the loader throw belts? A: Yes, but belt size, alignment, worn pulleys, contamination, and driven-component bearings must also be checked.
Q: Is this the cooling-fan pulley? A: No. It is identified as the drive-belt tensioner assembly replacing 6735884.
Q: Will it fit every Bobcat 753? A: No. Bobcat serial breaks matter; compare the original assembly and parts catalog.
Q: Is this an original-equipment part? A: No. This is a new aftermarket product. Brand names and part numbers are used only to identify compatible applications.
