Starter Motor Pinion and Flywheel Gear Ring

[Klaus Schlueter]

Hi all,

is it correct that the pinion of the starter motor and the gearring on the flywheel are not lubricated (running dry)?

If so, is it advisable to smear some grease onto both teeth (as far as possible) when I install the new uprated starter motor as there is a new pinion running on an old --and I guess worn-- gear ring?

Hope you can help. Many thanks.

Yes, you are correct, they run unlubricated. Putting grease on them won't help as it will simply get flung off at the rpms involved, and could (just) lead to clutch contamination. But the splines the starter gear slide on might benefit (something at the back of my mind is saying you should use a special dry graphite lubricant there, hopefully somebody with a better memory than I will confirm or refute that).

Hi Klaus

Have you considered replacing the ring gear whilst your at it? It's a straight forward job provided you have access to an oven.

Interesting post. Don't forget wear on the gear will on be in one or two places on the gear as the engine stops in the same place. 90 % could look new but its the 10% that does the work. Obvious to some but unknown to others

Bruce, I have considered it but of course I try to avoid that! That's why I aske here on the forum as I learned from my previous thread concerning the electric connection of the uprated starter that some of the members have changed the unit already. How are their experiences? And what do the professional Stag repairers know about this subject?

Edd, very interesting! I didn't know it and would like to understand these facts. Do you know the reason?

It's mainly due to the crank coming to rest on its next cycle. Ie no ignition so it free wheels until the next point of being the compression causing the most resistance then stops in the same place.i would have thought a v8 had more stop places but the idea is to check these wear areas not the rest. I'm not a expert in this so most of it is my understanding but I'm not far off I used to replace the gears and was always a heart stopping moment dropping them on hot hoping they sit nicely. The remove you just drill a hole in the side and ping they come off.

Many thanks Edd, I will think about the stopping situation and check the ring gear carefully.
