New Style Starter - Part Wanted
Posted: 18 Oct 2020 20:35
Evening all,
I've been investigating the upgrade/refurbishment of the new style starter mechanism fitted to the Kokusan ignition Morinis.
For those who don't know, this starter engages from a smaller motor via a two shaft sprag clutch assembly with a cush drive. The unfortunate thing is the cush drive material degrades and disintegrates over time (they are getting on for 30 years old!!), often making its presence known by bits in the sump and a rattling from the starter. NLM made an aluminium piece to replace the cush drive which did the job but after a few years has been known to disintegrate. I fitted one of these to my Coguaro and on the recent rebuild mine had indeed developed significant wear.
Now what am I after? Well to fit the NLM conversion you have to clean out the remains of the rubber cush drive and remove the metal containment ring to allow the new pieces to go on. As part of my investigations I have got hold of some cheeses (those who know will understand!!) made of Vulcolan 90 as originally specified by Ing Lambertini but not implemented by Cagiva more than likely due to cost. To fit these I need the containment ring and I'll be blowed if I can find the one I took off mine. I know I didn't throw it out but having cleared out all my hidey holes I have had to admit defeat.
So if anyone has a trashed unit with a containment ring I would be interested.
For those of you with the new style starter (Dart, Coguaro, Excalibur and New York) I hope to come up with an effective economic way of repairing the starter other than the laborious carving of bits of rubber or using bits of suitable diameter O ring.
John.
