Starter motor sticking?

For the last couple of days I have been getting a noise on start-up which sounds a little like a dry bearing. After a quick rev of the engine the noise goes away, I am assuming, as the starter disengages and all is then as normal. I will remove the starter to investigate, but can anyone suggest a reason as to why I am getting this symptom? I have the wadeing plug fitted and have not been through any unusually deep water in the last couple of weeks anyway. Obviously (200Tdi) the starter is the pre-engaged type and is engaged by the solenoid before the motor starts to run. I guess that there is a spring that returns the pinion once the key is released and the solenoid returns - other than the solenoid return spring that is? Any suggestions where to apply oil or grease to resolve this problem?

Cheers

The starter dog mechanism should be bone dry Chris. Any lube will attract dust/grit, which would jam the mechanism. The solenoid piston has a return spring, and then there's an operating fork that links the piston to the starter dog via a pivot point between the two. You can bench test starter motors with an old battery and a set of jump leads and you can easily see the mechanism working (or not). It might be worth mentioning that there's a directional clutch behing the starter dog - you should be only able to turn the cog on it's own in one direction.

This says it all then...

There are two pictures to show the amount of end float on the shaft - looking at an old starter I have here (awaiting reconditioning) there is an awful lot of end float! It can be pushed further out than in picture 2, +/- 5mm or so in total.

There is a lot of what I think is ATF about... This also explains the clutch slipping little. How will I tell for sure if it is ATF or engine oil? It is well black from clutch dust anyway. :(

Short term I think I will buy a new starter and then degrease it next week when I fit a new clutch and do whatever needs doing to the gearbox/engine oil seals... It has to be ready to go to Wales on Friday. On the bright side, at least I found this out before Pyrenees week. :)

The trip away to Wales was supposed to be the shake-down run for the Pyrenees. I guess it still will be to some extent - but the clutch will get changed and the leak mended before we depart for the foreign. :) If I could only decide on the type of oil...

No problem tomorrow, hopefully the Landrover will be OK but failing that I can nick Sandbag's car. :)
