Series 3 starter motor

It's not pre-engaged on the Series, any of them, it's the same as the old Austin Westminster. I don't know the Lucas number though.

The number sounds familiar from something, but I'm damned if I know what.

OK, thanks. Obviously a dud lead! I was struggling to find the link between LR and Triumph!

In that case then I think the Triumph Renown would have the same starter, as would the same engined Standard Vanguard.

Why not get the existing one rebuilt (or does it not have one full stop?)

Series 2.25 Diesel has a pre-engaged starter motor. Petrol versions use either a M418G with bendix or a 2M100 with bendix. Diesel versions use a Lucas, but the only reference number I can find is on Series 3, a Lucas 26321 - this appears to be the later fully sealed type, similar to the 2M100. Early Series 2A diesels appear use a pre-engaged M418G. Petrol versions with a bendix use a two bolt fixing, diesel pre-engaged versions use a three bolt fixing. The two bolt fixings are fairly standard, the holes are normally 180deg apart, however 3-bolt fixings seem to come in a bewildering array of different configurations, depending on fitment.

It's worth noting that Lucas M418G starters were used in a wide variety of applications, from bendix to pre-engaged, also with reduction gearboxes, and even as a motor to power hydraulic systems - just with a simple gear on the end. M418G only refers to the motor, not the attachment. An awful lot of British 50/60/70's cars used a M418G of some description.

I do have an automotive electrical after-market parts catalogue in the garage, this might cross-reference your Stag to a LR part, I will have a look at it tomorrow.

Alex,

Fascinating. Thank you. It is amazing what you can find out on this list! Maybe the solution is to find another M418G and just swap the motor part (which is giving me the problem as it is too weak to turn over the engine) - and yes I have made sure it isn't a dud battery - at one point I had two land rover batteries in parallel connected directly to the motor and it still only just lurched over! (And did those leads get hot......)

Cheers

Thoughts that spring to mind (in no particular order):

- worn bushes causing polling. A cheap, easy fix.

- worn brushes/commutator. A cheap, slightly harder fix.

- buggered armature. An expensive easy fix (so long as you can find a replacement armature)

And further to this:- Type M418G Lucas part no. 25605 L/R part no. 236287 with sundry repair kit L/R part no. 244718 but probably N.L.A

Type 2M100 which is a direct replacement for above, and supercedes it L/R part no. RTC3854 Sundry repair kit 90608178 which are available. If you need the Lucas part number to cross reference with the Triumph I can look at one and post later today.

That may work, however, be aware that the length of the nose of the starter can differ as well, which means that the length of the rotor changes....
