WOSP high torque, lightweight, gear reduction starter motors are manufactured in the UK. Unlike alternatives in the market place these are built using only 100% OE parts and units, therefore can't be rivalled on quality.
In most cases WOSP starters are designed with an indexable 360 degree mounting plate meaning no obstruction should get in your way when installing.

The main advantages over the original starter is the durability along with a weight and space saving. The improved performance means they also reduce loads on the vehicle's battery and electrical system.
Direct replacements to the original item, plug & play / fit & forget.
All units come with instillation instructions and a 12 month warranty.

  What Is This Part?

The starter motor is the electrically powered component that cranks the engine before it can run under its own power. Its drive engages the engine’s ring gear, allowing the motor to turn the crankshaft through the initial starting cycles. It works with the battery, starter control circuit, main power cable and engine earth connection. Because faults elsewhere in this circuit can produce similar symptoms, diagnosis should establish that the starter itself needs replacement.

What Does This Part Do?

• Cranks the engine: Converts battery power into the mechanical rotation needed during starting.
• Engages the starting drive: Connects the starter’s rotating drive to the engine’s ring gear for the cranking phase.
• Responds to the starting command: Works with the vehicle’s electrical starting circuit when engine starting is requested.
  
  Why Replace This Part?

A starter motor may need replacing when internal electrical wear or mechanical damage prevents it from cranking the engine correctly. Worn brushes, deteriorated solenoid contacts or bearing wear can contribute to slow, intermittent or absent operation. A damaged drive can also cause engagement problems or abnormal noise during starting.

Before replacing the unit, check battery condition, main cable connections and earth straps. High resistance or an inadequate electrical supply can make a serviceable starter appear faulty. If testing confirms an internal starter fault, replacement addresses the affected assembly rather than leaving the underlying problem unresolved.

When to Replace This Part?

• Clicking without cranking: Investigate repeated click-but-no-crank episodes after checking the battery and connections.
• Slow cranking: Consider replacement when testing confirms poor starter operation despite a healthy electrical supply.
• Intermittent starting: Investigate a starter that operates inconsistently, including faults that appear when hot.
• Failure to engage: Inspect when the starter can be heard spinning but the engine does not turn.
• Grinding or scraping: Check the starter drive and mating ring gear for damage before fitting a replacement.
• Visible damage: Assess damaged terminals, housing or mounting points during removal and inspection.
  
  FAQs

• Can a weak battery cause the same symptoms? Yes. Load-test the battery and check voltage drop through the main power and earth connections before condemning the starter.
• Does a click prove the starter has failed? No. Clicking can accompany an inadequate power supply as well as a starter fault, so electrical testing is needed.
• Should the starter be replaced if the engine cranks normally but will not start? Not without diagnosis. Normal cranking indicates that other causes of the no-start condition should be investigated.
