Assuming no one has repaired your starter in the past with bits from another you should find the model number (like M45, an arrow showing direction of rotation, and possibly the Lucas part number stamped on the cylindrical body of the motor part.I very strongly suspect that the pinion throw will need to be adjusted when a new solenoid is fitted. I do not have the data for your starter so I can not tell you what the gap between the pinion and end bracket should be when energised with 6 volts. This could also be a worn motor brush problem (being intermittent) so it would probably be best to get the whole thing tested and repaired. Most larger towns have a starter and alternation repair specialist so its a question of looking on-line (BR phone book, Yell etc.) to find your local one. Take careful note where all the wires go and record it BEFORE you take the starter off.

Sorry, I was not trying to suggest that you read the information with the starter on the engine. Rather that once it was off you would have more chance to see the numbers and arrows. You may be lucky and get through a season but my advice is to get it tested and repaired now rather than get let down miles away from anywhere. Changing the solenoid really only involves two bolts and unhooking the armature but setting the pinion throw requires a 6 volts supply I think, plus feeler gauges and a dimension I do not know. If the pivot for the arm that is used by the solenoid to move the pinion has no locknut on it and no arrows cast into the motor casting then no adjustment is required. If you remove the solenoid and clean the armature again no adjustment is involved. I think that you can even take the contact cap off the solenoid for cleaning and no adjustment is required. However to do that you need to be a dab hand with a large soldering iron and make sure it goes back on the same way it came off. Tony Brooks
