I am in need of a Lucas M35A 6V or 12V Starter Motor for a J2. After years of using a 6V in a 12V J2 the commutators have finally worn away and need replaced.
If you have an armature that would work too.
I would also entertain sending it to a good shop to be repaired, but could use some advice on where to send it.
Thanks in advance.......

| They may a bit harder to find in the US but the best way is to convert a later starter that was used in many BMC/BL cars use your front plate and starter dog and you have a 12v 4 pole starter. |

Terry, by front plate, do you mean the plate that bolts up to the engine? I guess the one at the front as mounted on the car carries the 4 brush holders?

| The front plate of the starter motor as the original is a 3 bolt mounting as opposed to the replacement 2 bolt you need to use the new rear plate as it has the 4 brushes if you are a perfectionist you would need to change the position of the power cable, I have used one like this for many years and replacements are cheap and plentiful. |

Further thought Terry, When you say front plate and starter dog, do you mean just that, i.e. using the modern armature? If possible, might it be easier to use the old armature and only the yoke/fields and back plate of the new motor?
Cheers,
Dave |

| The starter dog assembly has to come off anyway to change the front plate and I am not sure if the old armature would match up to the four pole field coils. |

Would a brief description of this "restomod" be a useful addition to the document downloads, technical section?
Even if the description is not detailed, the fact that it is possible and has been successfully done is useful to owners who are not aware of the possibility. |

Thanks Terry. I assumed (always a bad idea!) that front plate and armature would come out as one.
Yes Nigel, an excellent idea if anyone is up for it.

Hello Boys,
you canīt fit a later, made from the mid 1950s on, BMC/BL starter motor to a MMM engine.
The flywheel ring gear of the later BMC/BL engines are different,
number of teeth and the desings of teeth.
Also the pinion gears of the stater motor are different.
@ Mike, if you canīt find the parts you need in US,
the M 48 starter motor for TC XPAG engines fits and work.
These starter motors are esyer to get in US.
This company rebuilds starter motors.

If you have no chance to get one - this could help to get the car running,

Carl, I think pinion question was covered above:

The TC XPAG tip could also be added to the restomod tip though; useful. |

Carl, I can't help feeling the OP would jump on a high torque starter on any Triple M car like a ton of bricks.

Trigger warning:
Those who are unduly sensitive and or have an originality fetish should read no further as to do so may offend and cause irreparable damage to their bibendum suits.
If it comes to a choice between originality but a non running vehicle and a pragmatic but unoriginal change to ensure running and enjoying a MMM, then I would go for a high torque starter and raise two trafficators to the OP! |

| My twopence worth ,12v and 6v armatures are interchangeable , field coils determine the voltage of a starter , armatures from 1950/60s m35s will not suit MMM [the pinions are not compatible ], field coils from 1950s/60s are compatible [early copper are better than later aluminium].The best combination I have found is m35a or very early m35g armature with 3 bolt flange,m35a body [looks better] m35g field coils, and m35g 4 brush holder plate. The TC starter [m418] needs angle grinder surgery to fit [the body and front flange foul the block ,at least on an N type. Geoff |
