Part Identification:
Visual diagrams (schematics) with exploded views clearly identifying each part and its corresponding part number.
Part Ordering:
Crucial for ordering correct replacement parts, ensuring compatibility and fitment.
Basic Assembly Reference:
Provides a fundamental understanding of how components are assembled, aiding in DIY repairs and maintenance.
Part Interchangeability Reference:
While not explicitly stated, parts lists can sometimes hint at interchangeable parts across slightly different models or revisions, requiring careful cross-referencing.
Part Number Lookup:
The primary procedure is the accurate lookup of part numbers for ordering and replacement.
Depth:
Highly detailed for parts identification and sourcing. Does not typically include repair instructions or diagnostic procedures, but is essential for any repair involving part replacement.
Schematic Detail:
Typically provides clear, often hand-drawn or digitized line art schematics for each major sub-assembly and component group.
Compatibility Check:
Essential for ensuring that parts from different years or variants (if any) are compatible, using the part numbers as a reference.
Digital Format Potential:
If digital, likely PDF with searchable text if OCR'd, otherwise image-based pages.
Digital Searchability:
If provided as a digital PDF, searchability for part numbers or component names (if text is embedded) significantly enhances usability.
Digital Access:
If digital, allows for quick searching and printing of specific pages relevant to a repair.
Original Print Quality:
Reflects 1990s technical documentation standards, typically clear line drawings and legible text.
Diagram Clarity:
High importance on the clarity of exploded view diagrams to accurately identify small or visually similar parts.
Original Binding:
Typically saddle-stitched or perfect bound for printed manuals.
Original Paper:
Standard quality paper for technical manuals, designed for clarity of diagrams.
Engine Type:
Likely a two-stroke, single-cylinder engine, typical for Beta trial bikes of this era. Specific displacement and bore/stroke not provided in product description, but Alpina 240 implies approximately 240cc.
Bore X Stroke Estimate:
Likely around 72mm x 60mm or similar, resulting in approximately 240cc displacement.
Horsepower Estimate:
Estimated 25-35 HP range, common for 240cc competition trial engines of the period.
Torque Estimate:
Estimated 20-28 Nm, typical for a competition 2-stroke engine.
Carburetor Type:
Likely a Dell'Orto or Mikuni carburetor, specific model number would be in the manual.
General Maintenance Focus:
While the manual is a parts list, understanding component wear based on part identification is key to preventative maintenance. For example, identifying specific piston ring part numbers informs when ring replacement might be due.
Engine Top End Overhaul:
Depending on usage, piston/ring replacement might be recommended every 50-100 hours of hard use. The manual would list the specific piston and ring part numbers for various oversizes.
Engine Oil Type:
Manual would specify recommended 2-stroke pre-mix oil ratio and type (e.g., semi-synthetic or fully synthetic for competition).
Transmission Oil:
Manual would specify the type and viscosity of transmission oil (e.g., SAE 75W/80 or 75W/90 GL-4).
Common Wear Items:
Based on the era and type of bike, common wear items include clutch plates, piston rings, air filter, spark plug, brake pads, fork seals, and wheel bearings. The manual details the specific part numbers for these.
Suspension Leaks:
Fork seals and rear shock seals are common wear items. The manual provides the specific seal part numbers for replacement.
