The Multiquip 21-2090 Rear Chain 5/8" Long is a genuine OEM replacement designed for TB11E and TB11G Tufftruck power buggies. Sourced directly from Multiquip, this chain matches the original specification for a direct, bolt-on installation with no guesswork on fitment. It is confirmed compatible with both the electric-start and gas-powered variants of the TB11 series. Keeping the drive chain in serviceable condition is critical to maintaining consistent haul performance on the jobsite.
Key Features
- Genuine OEM Chain Integrity — Manufactured to Multiquip's original link pitch and tensile strength spec, ensuring consistent load transfer through the drive system.
- Correct 5/8" Pitch for Direct Installation — Sized to mate directly with the existing sprocket configuration on TB11 series buggies, dropping in place of the worn chain without modification to sprocket spacing or tensioner position.
- Confirmed TB11 Series Fitment — Verified for use on TB11E and TB11G Tufftruck power buggies by Multiquip part number 21-2090.
- Drive System Continuity — A worn or stretched rear chain causes slipping, loss of tractive effort, and uneven load hauling; replacing it restores full power transfer from the drivetrain to the rear axle.
- OEM Part Number Traceability — Ordered and fulfilled under part number 21-2090, eliminating substitution risk when restocking or cross-referencing against service documentation.
The rear drive chain on a power buggy transfers rotational force from the drivetrain to the rear wheels, allowing the machine to carry and move heavy concrete loads across a worksite. Over time, chain links stretch, wear, or develop tight spots that reduce drive efficiency and place added stress on sprockets and bearings. A worn chain left in service can ultimately lead to skipping under load or complete drive failure, so timely replacement with the correct OEM chain is the most straightforward way to restore full haul capacity.
