Starter motor Series 1 Jota

I got my starter motor today and unfortunately (my school boy error), the motor comes with a 9 tooth bendix drive and I needed a 14 tooth drive. They claim (probably rightly) that the motor I bought is entirely compatible with the MO 102 (which also has a bendix drive with 9 teeth). Reality is I should have got the MO 102LB which has interchangeable drive gears. Lesson learned. I've messaged them in the vain hope that they might have a 14 tooth bendix gear that will fit.  The cost of shipping it back will likely cause me to write this one off to experience (All 250 Euros of it).  If that proves to be the case, I might have a starter motor to give away :(

Bugger!!
 
I'm sending two starters for refurb today, to Robson & Francis in London, as recommended by fellow Laverda owners.
Bosch unit for a 180 and a SJCE unit for a 120.

They strip and assess them, then advise what work is needed and how much. If I decide not to proceed, they charge 10 quid for the return postage, that's all.
Will report back in due course :)

Hi Piet, do have a Bosch part number for the field coil assembly? Is there a kit? Thanks!

You mean, like in "Repair your starter in 3 easy steps on a Saturday arvo"?  No. 

The field coils come pre-assembled and need to be fitted to the clean, de-rusted housing.  Also, soldering the brushes is involved, you need a big soldering iron for that.  Dunno about the Bosch part #, will have to check.  1:15am here, nah, not now...

Update.

A few weeks later, both starter motors were stripped, inspected and rebuilt - field coils removed and re-insulated, armature rewound, new brushes and bearings fitted and the outer casings shot blasted and resprayed. GBP?280 each.

I've not had the opportunity to test them yet, but I now have two 'as new' starter motors on the shelf for future use.

Great service and good communication throughout from the guys at Robson & Francis :)

Thanks Piet..I am curious if the BMW airhead starter field coils are the same as Laverda? The BMW parts are plentiful and cheap.
