*Must* be engaging? Isn't the pinion thrown forward into engagement
with the ring gear due to its interia and being on mounted on the
coarsely threaded shaft of the starter motor. If the pinion is sticky
on the shaft the motor will still spin but the pinion not engage. This
fault can be a random in nature as the shocks from the motor starting
and stopping can free the pinion... Fits the OPs orginal description
fairly well.

Old inertia type - that's right. Modern pre-engaged type have the
solenoid push the pinion into mesh.

And Landrovers have the **Modern** type??? Wow, theres a suprise.

The 200/300Tdi (and optionaly 2.5TD) starters being the "modern" type.

But not *must* be engaging, it all depends on the timing of contact
closure in relation to expected pinion position. However that is straw
clutching. B-)

Bu what ever spining without apparent engagement is a starter fault
either a sticky pinion on shaft or sticky clutch.

> And Landrovers have the **Modern** type??? Wow, theres a suprise.

I suspect there is a change over period sometime in the 70's or 80's.
Or prehaps between series and Defender, I'd expect Discos, Rangies etc
to be all pre-engaged. B-)

Going back to the 2.25 engines on the Series III, the petrol and diesel
engines have totally different starters. The petrol has a relay-only
solenoid on the bulkhead, and (I think) an inertia starter. The diesel
has the solenoid on the starter motor, closing the contacts and
physically moving the pinion into mesh. As an ex-farmer, I tend to think
of the latter type as standard, and don't have a special mental label
for it.

Well its off...And its a Valeo Starter Motor. The motor housing and
cables seem in good nick and the small cog (dont know what it should
be called) on the end of the motor doesnt look too warn considering
its done 150,000miles. The ends of the teeth are only very slightly
warn.

So, I guess its time for a new solenoid.

The "small cog" or pinion should be stiff to turn by hand in one
direction and impossible to turn by hand in the other. If it is easy to
move then that is your problem. The clutch that lives inside the pinion
has failed.

Good luck

Thanks for this Marc,
The pinion would move round in one direction, but not in the other.
So from above clutch is OK?

Thanks
Jon

 
>Thanks for this Marc,

>So from above clutch is OK?

Yes sounds OK.

When the clutch does fail the starter will normally engage ok but will
spin out after a couple of turns and "wizz". Not normally a problem on
TDI engines. The TD engine using the same starter requires much more
cranking to get started and they knacker the clutches more often.

This is what I suggested right back at the start of this thread.
Incidentally, they sometimes fail so that they seem ok by hand too, and
the only way to be sure is take a leap of faith and replace them.

Ok guys, head scratching time....Perhaps.

Richard promptly delivered the new solenoid so I put it all back
together last night.

On the first turn of the bloody key there was lots of whining and
starter motor spinning noises but no engine turning over.

Given this is exactly the same as what was happening before the new
solenoid, perhaps its the clutch?

After a lot of swearing I decided to take it all appart again and put
my old solenoid back on and closely examine the teeth on the flywheel.



Flywheel:
Looks like new, no badly warn or missing teeth.

Starter:
With the starter motor on the ground and a spare 12V supply I fired up
the starter. Instantly the pinion flys out and I can hear the same
noise that I can when its on the motor (using both solenoids).

An interesting point that my father pointed out was that when the
starter was spinning but not starting the engine was that the fan was
turning ever so slowly???

This would be indicitave of the starter motor clutch would it not??
Assuming that the starting resistance of the 200tdi is greater than
the ability of the starter clutch to lock out fully?

Also, I decided to take the starter appart last night. The workshop
manual says that there should be a rubber pad (item 10 in the link
below) in amongst the clutch workings - I have absolutely no traces of
this left in the body.

Starter motor brushes, windings and magnets all look fine.


Options:-
1. Someone mentioned the clutch a while back. Would that be the
general concensus now? If so can I buy a new clutch assembly?

2. Buy a new starter motor...Are they exchange units?
3. Is it worth getting one off a scrapper?

Any advice please. I really need the vehicle back on the road.

thanks
Jon

sounds a lot like it, unless the ring gear is loose on the flywheel. Unusual
but not unheard of. More likely that it'd fall off altogether than slip
though, I would think.

>2. Buy a new starter motor...Are they exchange units?

generally, yeah.

>3. Is it worth getting one off a scrapper?

pays yer money and takes yer chance, innit. You could get a good one, you
could have the same fault or a different fault. If it's dead-easy to get
apart, worth it. If it's a PITA to get off and on again, then I'd go with
an exchange one to avoid having to do it again too soon.

New one seems to be ball park £100

Its a definate PITA to get on and off

New "clutch assemblies" are ball park £40.

Several other people have said clutch assemblies tend to be quite
consumable on these so its getting a new assembly put on tomorrow.

Fingers crossed!!

I'd image that an exchange recon should be slightly cheaper than that?
Just had the one for my car done and it was about £70

Ok - I rest my case. Do what you should have done to start with - buy a
new one way clutch/pinion assembly, fit it, and it'll work again.

Poor electrical supply, usually through earthing circuit.
try running starter motor directly with jump leads, if it works then
this likely to be problem,
Or battery not delivering enough amps, check with a clamp meter or jump
lead your battery to another battery.
