Description
Overview:
This is a genuine Husqvarna gearbox bush (part no. 503 32 44-01) designed to support and guide rotating shafts inside walk‐behind mower transmissions. Made from durable, precision‐machined metal, it acts as a wear surface to reduce friction, maintain shaft alignment, and keep the gearbox running smoothly. It replaces worn or ovalised bushes that can cause noise, vibration, or play in the drive. Built to Husqvarna's original specifications, it ensures the correct fit and function in compatible gear boxes, including popular models such as LB448S and LB548Se. Choosing this OEM bush helps restore performance, extend service life, and protect other drivetrain components from premature wear.
Key Features:
- Genuine Husqvarna OEM component for assured compatibility and quality
- Precision metal sleeve provides stable shaft support and smooth rotation
- Manufactured to factory tolerances for a secure, accurate fit
- Helps reduce gearbox noise, vibration, and uneven drive
- Durable construction for long service life under load and vibration
- Designed for seamless integration in specified Husqvarna/Klippo gear boxes
- Straightforward to install with standard workshop tools
- Supports efficient maintenance by replacing only the worn bush, not the full gearbox
- Helps protect gears, seals, and shafts from accelerated wear
- Suitable for professional and domestic mower servicing
Typical Applications:
Used when servicing the drive gearbox on walk‐behind mowers to correct shaft play, rough running, or excessive noise. Typical replacement points include input or output shaft locations where the original bush shows wear. Ideal for routine maintenance, workshop overhauls, and in‐season repairs to keep lawn and grounds care equipment operating reliably and efficiently.
