Description

Overview

Clutch Belt Tensioner Thermo King SLXe SLXi keeps the clutch belt drive loaded correctly on later no-pulley setups used across these trailer refrigeration units. Because the pulley is separate, it suits repairs where the tensioner body has worn, started to bind, or lost stable belt control.

Features

• Automatic clutch belt tensioner supplied without pulley.
• Built for Thermo King SLXe and SLXi trailer units, including 100, 200, 300, 400 and Spectrum variants.
• Separate-pulley format suits later replacement setups rather than older one-piece tensioner styles.
• Useful when the arm or spring action has worn but the pulley choice still needs to be handled separately.

Specifications and Materials

Clutch Belt Tensioner Thermo King SLXe SLXi is the automatic tensioner assembly for the clutch belt drive and is sold without the pulley. It suits the later separate-pulley arrangement, so match the existing setup before ordering if the unit has had earlier drive parts replaced over time. Part number: TK-77-3251-AM.

Compatibility and Fitment

Check that your unit uses the later clutch belt tensioner without pulley, then match the SLXe or SLXi series and the separate-pulley layout before ordering. This cross-reference listing means this part is a suitable replacement for the part numbers and applications shown. Some changes in installation may be required. 77-3251, 773251, 77-3189, 773189, 92-9487, 929487, 77-3228, 773228

Compliance and Safety

Shut the unit down fully before belt work because this assembly sits beside moving pulleys and spring-loaded drive components. Also inspect belt condition and pulley condition at the same time, because a fresh tensioner cannot correct a damaged belt or a worn pulley on its own.

Trailer Applications

Clutch Belt Tensioner Thermo King SLXe SLXi suits clutch belt service on SLXe and SLXi trailer units when the tensioner body no longer holds steady belt pressure. It also suits upgrades from older with-pulley tensioner layouts to the later separate-pulley arrangement, which is why buyers should match the existing bracket and pulley style before ordering.
