Upper Bracket Function
The 576420702 serves as an upper structural bracket within the applicable handheld equipment assembly.
A simplified arrangement can be represented as:
Upper Bracket 576420702 → Cushion / Supported Assembly → Lower Bracket 576420802
The exact configuration varies by model, but Husqvarna parts diagrams show the upper and lower brackets positioned with associated clutch, cushion, bearing, and housing components.
The bracket helps maintain the physical relationship between these components during equipment operation.
Upper & Lower Bracket Arrangement
In applicable equipment, 576420702 is paired with:
576420802 – Lower Bracket
The two components occupy different positions and should not automatically be treated as interchangeable.
Upper Bracket
576420702 – installs in the specified upper position.
Lower Bracket
576420802 – installs in the corresponding lower position.
Their shapes, mounting relationships, and surrounding components are determined by the specific equipment design.
M5x0.8 Identification
The factory description specifically identifies the component as:
BRACKET UPPER M5X0.8
The M5x0.8 designation refers to the metric fastener/thread specification associated with the bracket description.
When servicing the assembly, use only the correct equipment-specific hardware and do not assume that visually similar fasteners are interchangeable.
Handheld Equipment Applications
Parts references identify 576420702 for a range of Husqvarna handheld equipment, including applicable:
- String trimmers
- Brushcutters
- Edgers
- Hedge trimmers
- Pole saws
Known model families using the bracket include applications such as the 125RJ, 130C, 130L, 322L, 522L, 524L, and multiple 525-series machines, although compatibility varies by production version.
Always verify the exact model and serial/product information before ordering.
Structural Support Function
A bracket's primary purpose is to provide a rigid mounting or supporting interface between components.
Within the applicable assembly, 576420702 helps maintain:
- Component positioning
- Mechanical support
- Assembly alignment
- Proper mounting geometry
- Separation between adjoining components
Because handheld equipment produces vibration during operation, correct bracket condition and mounting are important.
Vibration & Bracket Condition
Trimmers and brushcutters operate at relatively high engine speeds and naturally generate vibration.
A damaged or loose bracket can potentially contribute to:
- Component movement
- Rattling
- Misalignment
- Abnormal vibration
- Increased stress on mounting hardware
- Wear of adjoining components
If the original bracket failed, inspect the surrounding assembly for the underlying cause rather than replacing only the bracket.
Common Reasons for Replacement
Replacement of the 576420702 M5x0.8 Upper Bracket may be appropriate if the original has:
- Bent
- Cracked
- Become distorted
- Developed mounting-point damage
- Sustained impact damage
- Developed excessive wear
- Become loose
- Been damaged during engine service
- Been damaged during clutch service
- Developed corrosion
- Been lost during disassembly
A bracket that no longer maintains its original shape or mounting position should generally be replaced.
Possible Signs of Bracket Damage
Depending on the exact equipment configuration, a damaged upper bracket may contribute to:
- Excessive vibration
- Loose components
- Rattling
- Improper component alignment
- Movement around the clutch or engine assembly
- Difficulty securing associated components
- Visible bracket distortion
- Repeated loosening of mounting hardware
These symptoms can also originate from damaged cushions, housings, bearings, clutch components, or fasteners.
Bracket Inspection
Inspect the existing 576420702 for:
- Cracks
- Bending
- Distortion
- Corrosion
- Enlarged mounting points
- Damaged mounting surfaces
- Excessive wear
- Missing material
- Impact damage
Pay particular attention to areas around fasteners and component-contact surfaces.
Lower Bracket Inspection
Whenever replacing the upper bracket, inspect the corresponding 576420802 lower bracket where used.
Check for:
- Cracks
- Bending
- Distortion
- Loose mounting
- Excessive wear
- Damaged fastener locations
Damage to one bracket may indicate that the adjoining bracket has also experienced abnormal loading.
Cushion Inspection
Husqvarna parts diagrams show 576420501 Cushion alongside the bracket components in applicable assemblies.
Inspect the cushion for:
- Cracking
- Compression
- Deterioration
- Tearing
- Distortion
- Missing material
A deteriorated cushion may allow additional movement or vibration within the assembly.
Clutch Area Inspection
Because Husqvarna diagrams place 576420702 in assemblies containing clutch-related components, inspect the applicable area for:
- Loose hardware
- Damaged clutch components
- Bearing wear
- Housing damage
- Excessive movement
- Abnormal wear
For example, Husqvarna's 525RS parts documentation shows 576420702 alongside the lower bracket, upper cushion, clutch housing, and bearing.
Mounting Hardware Inspection
Inspect applicable:
- Bolts
- Screws
- Washers
- Retainers
- Threaded mounting points
Look for:
- Damaged threads
- Bending
- Corrosion
- Missing hardware
- Stripped mounting points
- Looseness
Correct hardware is necessary for the replacement bracket to remain securely installed.
Upper Bracket vs. Lower Bracket
Do not select the bracket solely by approximate shape.
The upper and lower brackets have separate OEM part numbers:
Upper: 576420702
Lower: 576420802
Always confirm which position requires replacement before ordering.
Why Correct Bracket Fitment Matters
Equipment brackets that appear similar can differ in:
- Overall dimensions
- Mounting-hole locations
- Contours
- Fastener configuration
- Component clearances
- Upper/lower orientation
- Equipment compatibility
An incorrect bracket may prevent surrounding components from aligning correctly.
For this reason, use 576420702 as the primary replacement reference.
Installation Considerations
Before replacing 576420702:
- Shut off the equipment completely.
- Allow the engine and muffler to cool.
