Husqvarna Floor Grinder Drive Plate 505033201 10 1/2 Inch Holder Disc (PG 820 HTC 800 RL Planetary Machine Mounting Diamond Resin Tooling Slabs)

Husqvarna 505033201 Holder Disc Mounting Plate

The Husqvarna 505033201 holder disc mounting plate provides precision diamond tooling alignment and dynamic balance for PG 820 and HTC 800 RL planetary floor grinders. Manufactured from heavy-duty stamped steel to factory OEM tolerances, this 10.5-inch drive carrier secures diamond grinding segments and resin polishing pads under continuous high-torque surface prep conditions. Installing this direct-replacement carrier disc dampens harmonic machine vibrations, prevents uneven tooling wear, and maintains flat floor contact across commercial concrete slabs.

Best Used For:

• Planetary Grinder Head Rebuilds: Replacing worn, warped, or vibration-damaged tool carrier plates on Husqvarna PG 820 and HTC 800 RL machinery.
• Tooling System Transitions: Adapting rotating grinder drive heads to accept both Redi Lock diamond grinding blocks and hook-and-loop resin polishing pads.
• Large-Scale Floor Leveling: Maintaining dynamic head balance and uniform downward force across multi-head setups to eliminate floor gouging.

Key Performance & Safety Features

• Factory OEM Precision: Engineered to exact Husqvarna and HTC manufacturing tolerances for flawless hub centering and zero radial runout.
• Heavy-Gauge Steel Construction: Resists mechanical warping, rotational deflection, and fatigue under aggressive grinding pressures.
• Dual Tooling Compatibility: Securely accommodates metal-bond diamond segments and velcro-backed resin polishing pucks.
• Harmonic Vibration Dampening: Balances rotating mass to protect upper spindle bearings and drive belts from premature mechanical wear.
• Corrosion-Resistant Plating: Industrial surface finish shields against rust, jobsite moisture, and caustic concrete slurry.
• Direct Bolt-On Fitment: Pre-drilled factory bolt pattern ensures fast, straightforward installation on planetary drive assemblies.

Technical Specifications

Pro-Tip: Check mounting plate flatness with a straight edge during routine maintenance cycles to ensure warped carrier plates do not cause premature diamond segment wear or uneven floor scratch patterns.
