Scandi Posted January 2, 2019 Share Posted January 2, 2019 Happy New Year! I'm experiencing an unusual problem with my 200Tdi 1993 110 Defender. The last few weeks I have noted when turning the key, the starter kicks in and whirrs but does not turn over the engine. After a couple of attempts it eventually starts fine. Now however it refuses to engage just about all the time. It is a Valio starter. I have taken it out as I thought the bendix might be gunked up on the shaft, but no. I have stripped, cleaned and reassembled it. I can move the bendix out all the way by hand without any difficulty other than the solenoid return spring. Bench testing also show the drive sprocket throwing out with force all the way and motor turning on as would be expected. I also thought the sprocket might be slipping in the one way coupling, but no. I'm unable to make it slip even when mounted in a vise and with a big wrench. When putting it back in the car it still does not seem to engage the flywheel. The teeth on flywheel and starter look fine although it has done some nearly 400,000 km. Any ideas?

steve b Posted January 2, 2019 Share Posted January 2, 2019 It sounds like the clutch/freewheel in the pinion assy. is slipping under load even though it feels tight on the bench ? Steve b Quote Link to comment Share on other sites More sharing options...
Scandi Posted January 2, 2019 Author Share Posted January 2, 2019 Hi Steve, Thanks for a quick response. I have been thinking just that, but I'm a bit sceptical since I have put great load on the sprocket when holding the shaft in a vise while trying to turn the sprocket with a pipe wrench. It won't budge even a bit one direction and is completely free the other. Quote Link to comment Share on other sites More sharing options...
western Posted January 2, 2019 Share Posted January 2, 2019 My starter occasionally does the same, but starts ok on the 2nd try, just living with it for now, will get a new starter soon & get the original rebuilt. Quote Link to comment Share on other sites More sharing options...
darthdicky Posted January 2, 2019 Share Posted January 2, 2019 Check the earthing too, mine used to to do similar and I think it was cured by putting a new earth strap from the battery box to the chassis. Quote Link to comment Share on other sites More sharing options...
Maverik Posted January 7, 2019 Share Posted January 7, 2019 Bendix clutch in your starter motor has worn out and is slipping - the wee barrel's wear in the wedge shaped holes and it no longer grips - it happened to me in April 2016 - i cut it open to have a look see. You can usually buy the clutch as a separate part and just replace. I would recommend this other than spending your money on a non original starter motor...

Scandi Posted January 7, 2019 Author Share Posted January 7, 2019 Hi, and thanks for your input. I was thinking the bendix clutch is buggered, but why is it working just as it should when I test it in the vise? I am unable to find a replacement part for this particular starter (Valio) here in Nairobi so I decided to get a new starter and that has worked well.
