The Multiquip 502010220 is a genuine OEM Adjust Bolt 10x50 MDR-9D/G designed for MDR-9D series power trowels. As a direct factory replacement, this bolt maintains the precise fit required for proper blade pitch adjustment on your trowel. Sourced from Multiquip, it matches the original component specification so you can restore your machine to full working order with confidence. DHS Equipment stocks this part so you can get your trowel back on the slab without unnecessary delays.
Key Features
- Genuine OEM Construction — Manufactured to the same material grade and thread specification as the original bolt, ensuring correct torque retention and resistance to the repetitive stress loads common in blade adjustment systems.
- Direct Drop-In Replacement — Sized at 10x50 to match the original mounting position on MDR-9D/G trowels, threading directly into existing hardware without rework.
- Confirmed MDR-9D Fitment — Verified for MDR-9D series Multiquip power trowels, so you can order with confidence knowing this is the correct part for your machine.
- Preserves Blade Pitch Accuracy — A correctly functioning adjustment bolt allows operators to dial in precise blade angles, which directly affects surface finish quality and troweling efficiency.
The adjustment bolt on a walk-behind or ride-on power trowel is a critical hardware component in the blade pitch control system. It allows the operator to set and hold the correct blade angle relative to the concrete surface, which determines the finish quality and the machine's ability to progress through each troweling pass. When this bolt becomes stripped, corroded, or breaks under load, blade pitch control is lost — causing uneven finishing, machine vibration, and the inability to complete a proper surface cure cycle. Replacing it promptly with the correct OEM part restores accurate pitch control and keeps the finishing process consistent.
