Starter Ring Gear Question

[A.K. Boomer]

ive got a spare starter that has a longer pinion on it ..but still the same amount of travel

the originals starters pinion looks unworn ..the wear has only taken place on the ring gear.



well... we will see ..put the old one back on .......if ok for a period of time ......it will be left on ....if not will swap for the spare one ..

spare one will have to be taken apart cleaned up ...its an unknown bought from car boot sale for £1

all the best..markj,

Holy crap is that the original ???
Very possible this could be your entire problemo...

to rotate the flywheel to a different position ..requires me to take the box out ........when the time comes to do that .....i will replace the ring gear..

No --- I said just get the starter properly fixed and then run it ---- but if it ever comes out then you might as well rotate things,

You most likely have enough ring gear teeth to scrap your car....



What pic above is the original? and what one were you using ?

[Mark McGrath]

Mr Sleepy and Terry G are correct.It`s a pre-engage starter and there is no spiral or helix.
He needs to disconnect the power lead from the solenoid to the starter motor and power the solenoid with the starter out the engine.He can then measure what travel he actually has,not what he thinks.
My money is on the sprag.

Aboard --- so it that the original up above?

they are way way different, you cannot JAM that lower one in and expect it to work good ---- it's way longer pinon depth !

unless there's been a mix up from the start... (no pun intended)

[aboard_epsilon]

the lower ones pinion ...is longer ..yes

but in such a way ..in that the extra length will be just be un-used..

the length of travel is the same.

but the starter field coil housing is longer ........i think this is a more powerful starter for the diesel version ..diesel version has same gearbox .

both are magneti marelli make

Aboard Epsilon yes quite right mine being back feed

I would be very surprised if there was no sprag clutch.
You can verify this if you still have the starter apart grab the pinion with a pair of pliers and hold the armature.
You should be able to rotate the pinion in one direction. It will probably take a bit of force.
