Some of you may be aware of my on-going starter problems. If not, a description can be found here:
https://www.defender2.net/forum/topic76268.html Decided to dive under the DC today to see what’s what with the starter, which I feel is the culprit. I noticed that there is a clear, 2mm gap between the ‘head’ or drive-end bracket of the starter motor and it’s mounting point, as per the photo. I gave up long ago assuming something like this would be wrong, as I have learnt what peculiar beasts Defenders are. However, I watched a video where a chap removed his starter from his 2.4 Tdci and before he started it was flush. Can anyone confirm what the case should be? Is this badly fitted? Is this an incorrect starter? It seems odd to me that it’s not flush as surely that adversely affects the drive pinion’s connection to the engine’s pinion? On a wider note, the starter not working a new battery draining in 48hrs, there seems to be a fair amount of corrosion around the solenoid. Could this be draining the battery? Hhhhhhhhhhhhhhhhhhelp!!

I don’t think there should be any gap there, so something is wrong.

Doesn’t look right, does it? As it happens I have finally resolved the non-starting problem, it was nothing more complicated than a 5€ battery swap in the fob. The old battery was affecting the passive immobiliser, hence turning over but not starting. With the new battery it starts like a dream now, but this gap is still curious. Monsieur Le Grenadier

Have you ever had the starter off/replaced? Almost looks as though it has been replaced with a locating dowel still in the housing and one on the starter meaning that it couldnt sit flush.
Other than that it must be the bolts are loose. Might be wrong as to which bit exactly the gap is showing in though! Steve 02' 110 TD5 Double Cab Rebuild Thread |

Normally there is an annular register on the starter motor which locates the starter into the bell housing. This is to ensure correct alignment of the starter pinion to the flywheel ring gear. The starter motor should also abut against the bell housing to ensure that the starter pinion correctly meshes with the ring gear, if there is a gap then you are relying on the tightening of the bolts to axially position the starter.
It may be worthwhile removing the starter, inspecting the flanges and refitting ensuring that the starter abuts against the bell housing prior to fitting the bolts. You can also look at the wear patterns on the pinion and ring gear at the same time. Not easy to explain but hope it makes sense. Defender 90XS SW Mini Countryman Cooper S Morgan Plus 8 |

Thanks all for answers. Wasn’t easy working today, -7c and snowing heavily. I’ve looked on line and the Britpart version (I have no actual idea of the make of mine) does seem to have a rubber grommet around the bracket, which may be what mine has. It will be filled with crud. I’ll give it a dig out and see what is in there. But it is starting perfectly normally. Indeed strongly.

Hello Grenadier
This is a close up of my replacement Starter Motor (also for a 2.4 MY2011).... from Land Rover Click image to enlarge A couple of observations: 1. If you DIY this it is possible but you'll become convinced that LR started with the Starter Motor and built the rest of the vehicle around it... a common observation when working it out as you go with self (harm) maintenance, but the whole job is in an area that is very tight / unseen / working blind and often at arms reach... but with care + time it's achievable, I dare say that some will find it easier than others. 2 Look again at your starting position, in particular the tightness of the bosses (to the left of the mating / sealing gasket) these come into close contact / alignment with the bell housing, it is possible yours is ok. From memory the Starter Motor locates 'positively' and 'nestles' into position nicely. 3 Going back to DIY if you do this yourself... as it may well feel like a semi-major effort consider carefully what you bolt on, you really don't want to do this too often. I've come to the view that saving so much but maintaining my own vehicle I tend to avoid any factored part containing either metal, rubber or any wiring 
Good Luck  SKIP
