Hofmann Monty 455 is a legendary, though now discontinued, workhorse in the tire service industry. Known for its versatility, it was designed to handle everything from standard passenger car tires to more challenging motorcycle and ATV wheels, including the notoriously difficult Harley Davidson belt-drive rims.
The "story" of its operation and maintenance is built upon several critical mechanical systems: 1. The Core Structure: Chassis & Body The foundation of the Monty 455 begins with its robust
(Part 2115456), which houses the internal pneumatic and electrical components. : The machine is enclosed by specific (3015444), (3015445), and
(2115500) panels that protect the inner workings from shop debris. : Clear safety and operational guides, such as the "Electric Risk" (3014098) and
(3015483) labels, ensure technicians navigate the machine safely. 2. The Clamping Power: Turntable & Jaws At the heart of the machine is the Complete self-centering turntable (2015590). Clamping Jaws Hofmann has largely moved on to the "geodyna"
: These (3008225) are responsible for gripping the wheel firmly. They move via a series of (2201203) and are driven by a Turntable Cylinder (typically Ø 75). Protection
: To safeguard expensive alloy rims, these jaws often utilize nylon or plastic protective covers. 3. The Bead Breaker: Forceful Precision
To separate the tire from the rim, the Monty 455 employs a side-mounted Bead Breaker Blade Assembly Complete Blade (2200140) is driven by a powerful pneumatic cylinder. : It is operated by a dedicated Bead Breaker Pedal
, which is strategically positioned to avoid confusion with the turntable controls. Return Mechanism : A heavy-duty Bead breaker spring
(3008952) ensures the blade returns to its starting position after each use. 4. Pneumatic & Air Treatment Systems As a pneumatic machine, air quality is vital for longevity. : The machine features a Water separator, pressure regulator, and lubricator
(2015577). This cleans the incoming air and adds a fine mist of oil to protect internal seals. : Over time, the Cylinder Seals
(e.g., Piston Gasket 4208231) are the most common parts requiring replacement to prevent air leaks and power loss. 5. Essential Accessories While the Monty 455 boasts a direct-drive system
No tire change is complete without the smaller tools that facilitate the process: Tire Lever : A standard Tire Lever
(3009516) is included for prying the bead over the mounting head. Lube Container Tire lube container with cover
(2200091) is mounted directly to the machine for easy access to mounting paste.
