starter motor

[rita]

2 Years ago I replaced the 2.2kW heavy duty starter with the 2.0 kW standard one.
Flywheel ring gear is the same for either model. It's impossible to change the solenoid
contacts.

The solenoid is on the bottom of the starter on the heavy duty one, and the solenoid
is on the top of the light duty one, so yo will have to wiggle the cables a bit but it all
works OK.

No problems since.

Hi Patnben,the bit I was concerned about was, Quote::old starter has 10 teeth but new 1 has only 9.

Quite right to be concerned BUT,

It's not economical to produce an engine with different flywheel ring gear for the odd
cold climate versions, I think this is determined when the vehicle is on the production line.
The heavy duty starter is 10% more powerful, 2.2 kW against 2.0 kW.
The heavy duty starter is probably capable of spinning the engine 10% faster
hence 10 teeth on the pinion.

So to my mind, it makes sence to design both starters to fit the same ring gear.
It looks right, feels right and sounds right and has never been a problem.

Do you have an alternative theory ?.

Ben.

Old starter 10 teeth

New starter 9 teeth Do you recon this will be ok.?

A few people have done the swap, not heard any adverse reports, Ben's been running it for a year with no probs & he ain't daft by a long shot, one of the people that it's a good idea to listen to when they tell you sumat.
if it fits & does the job, what's the worry, different number of teeth, different diameter? Are the teeth the same size? If they weren't I'd have thought it would be immediately obvious by the horrible noises that would result. It's the same engine doing the same job, as Ben said why would they fit a different flywheel?

hi all,
thanks for all your input especially like to thank patnben for reassurring me that the starter motor will fit & do the job ok.the new 1 is a OSGR 2 kw,i got from bongobits. didn't get a chance to fit today because of weather, but will let you all know how i get on. hopefully get it fitted tommorrow. thanks again.................... steve

Steve,

We have an opportunity to clear this up, I still have my old heavy duty starter
and could measure the distance from the centre of the pinion to a fixed point
on the starter. If you did the same thing with your new light duty starter then
we could calculate the difference in the distance of the pinion to the ring gear
which would allow both types to fit if it were different.

hi Ben,
fitted new starter motor yesterday i didn't bother measuring anything but it fitted in with no problems & fired up first time. it all seems fine hopefully there will be no problems as you mentioned before there no reason why it shouldn't have fitted. so i think we can safely say that both types of starter fit ok & do the job. thanks for your help....steve
