Diagram reference number 6
What This Product Does
The rotating impeller supplies cooling airflow within the air-cooled engine assembly. It works with the surrounding housing and ducting; it is not an electrical generating unit or a replacement for the complete alternator.
Functions
- Moves air through the cooling assembly.
- Supports heat removal from engine components.
- Replaces an impeller with damaged or distorted blades.
Technical Details
- Part number: 90110601003.
- Blade count: 11; fan diameter: 245mm; pulley diameter: 3.75 inches.
Symptoms of Fault
Reasons to inspect the fan include unusual vibration, scraping sounds, fractured blades, distortion or contact marks inside the housing. Higher engine or oil temperatures can also warrant a cooling-system inspection, but do not confirm an impeller fault on their own.
Why Replacement Matters
Renewing a damaged impeller addresses impaired airflow and mechanical imbalance. Before fitting a replacement, inspect the housing, mounting hardware, belt alignment and alternator bearings so that an underlying assembly fault is not left unresolved.
FAQs
What should be checked if the fan rubs?
Inspect assembly alignment, hardware security, spacing and housing condition rather than assuming the blades alone are responsible.
Does this replace the alternator?
No. This component is the fan / impeller; the diagrams identify the generator and housing separately.
How should suitability be confirmed?
Compare the vehicle details, engine references, fan dimensions and pulley specification with the existing assembly before ordering.
