As a direct OEM replacement, part 18129 is produced to the same specifications as the original hardware that ships on these machines. Whether you are restoring a worn tub assembly or completing a scheduled repair, this pin delivers a straightforward, no-guesswork installation. DHS Equipment stocks genuine Multiquip parts so you can source what you need and get your buggy back to work.
Key Features
- Genuine OEM Construction — Manufactured to the same dimensional and material specifications as the original pin, ensuring the tub frame assembly seats and pivots correctly without slop or accelerated wear.
- Direct Hardware Replacement — Drops into the existing tub frame cross mounting points on WBH and WTB series buggies with no rework to surrounding components.
- Broad WBH and WTB Fitment — Confirmed for WBH16, WBH16E, WBH16F, WBH16EF, WBH16EAWD, WBH16EAWDF, WBH21EPA, WBH21EFP, WTB16, and WTB16PD power buggies.
- Structural Integrity at the Tub — A correctly fitted cross pin keeps the tub frame rigid and properly aligned under load; a worn or missing pin leads to tub movement, uneven dumping, and premature stress on surrounding frame components.
- Verified OEM Part Number — Order with confidence using Multiquip part number 18129, the exact reference used in the manufacturer's parts documentation for these models.
The tub frame cross pin is a structural fastener that locks the cross member of the buggy's tub frame in position, maintaining the geometry of the tub assembly during loading, transport, and dumping cycles. Without a correctly sized and seated pin, the tub can shift laterally or rock under load, placing stress on welds, pivot points, and the dump mechanism. When this pin wears, bends, or goes missing, operators may notice excessive play in the tub, difficulty controlling the dump angle, or visible movement in the frame structure — all of which affect both productivity and operator safety on the pour.
