jointcbvirginmedia.com Posted May 12, 2019 Share Posted May 12, 2019 Hi,I’ve got a 1.4 K series. Every now and then regardless of the engine being cold or hot the starter motorplays up. When I press the start button, it just makes a whining noise.If I turn the ignition switched off get out and and rock the Caterham back and forth in gear.Then then get back in press the starter button with the ignition on, the engine will start normally. It has got a lightened flywheel fitted and covered about 4K miles from new.Any advise would be appreciated.RegardsJon Link to comment Share on other sites More sharing options...

I once had a Morris Minor with a bent starter motor shaft. It behaved just like that. I kept a spanner in the glove box to turn it a bit.I'd imagine that other faults in the Bendix drive or the engagement with the flywheel could do the same. So start with visible inspection of the starter motor and the teeth on the flywheel all the way round....I'd also check the battery voltage at rest, minimum during cranking when it does start, and at 3,000 rpm.And all of the relevant wires and connections including the earths.Jonathan Link to comment Share on other sites More sharing options...
SM25T Posted May 12, 2019 Share Posted May 12, 2019 Sounds like the bendix isn't flying out to engage the flywheel teeth if it isn't cranking the engine. Remove the starter and clean the external mechanism with petrol or brake cleaner. Link to comment Share on other sites More sharing options...
revilla Posted May 12, 2019 Share Posted May 12, 2019 Do you know what kind of starter you have? If not can you post up a photograph? Some of the early ones used direct drive starters with Bendix gear but most K Series as standard had a geared Magneton starter which was if the pre-engaged type, meaning that the solenoid physically engages the gear before it makes the contact which turns on the motor and so if the gear doesn't engage, the motor can't power up. A lot of them have then had these replaced I've the years with WOSP, Bride etc. The symptoms you describe would probably indicate different things in the different kinds of starter. To be honest whatever the fault, the most likely best remedy would be to have the starter motor overhauled by a local motor factor or auto electrician.
