Dunno about setting a new spring, sounds like a pretty hazardous job, but you could do a kickstart conversion or pullstart conversion instead.

haha your probably the 3rd person to say that. i already have the spring coming. i suppose i should take photos and make a write up if it goes well.

Good luck.. it is not supposed to be user serviceable :/ it can be fatal to service it.

I've heard bad things can happen if you try to do it yourself.

Good luck. Don't die.

Death by spring. If I had to choose a way. This would be it.

Any ideas on how to wind this be thing up?

Here is how i put this into here.

after trying to hold the spring by hand and have some one hold it together.... i decided i need some kind of jig.

out of a 2x6, piece a dowel, and a lagged bolt i came up with this.

the circle is the point where the spring would slip into the case.

what i did was hook the spring over the bolt and the gear over the dowel. then strapped a giant zip tie 36" (from hardware store)

as i spun the gear, i had someone else zip closed the spring.

(i ended up spinning the jib to get the leverage without letting go of the gear)

after the spring reached a point within the circle. just lifted it up and set it in the case. some strategic positioning of the zip tie head might be needed. but as it slid in the case slid the the zip tie off. bolt on the safety plate as fast as you can. DONE.

may need to carefully pry out the zip tie. the spring will pinch sandwich it against the case. needs no detailed explaination.

Where did you buy the spring? I cant find one anywhere.

Re: Honda NC50 Install new starter spring

Must have got lucky and found it on eBay.

Re: Honda NC50 Install new starter spring

They aren't available anymore. I got lucky that my local Honda motorcycle dealer had been around since the 60's. So they had a couple. That was years ago tho.

Re: Honda NC50 Install new starter spring

The answer to your original question, "how tight to set new spring" is really about what diameter is needed to drop into case. These were never meant to be taken apart. Rather they sold the entire transmission cover. Security torx in the 70s is what keeps those springs in place for a reason.

Looking at parts diagrams will affirm that the spring was never available separately from Honda. Too much liability that way.

Congrats. (edited)

Re: Honda NC50 Install new starter spring

If just the spring end is broken , it can be 'fixed'.

Clean the spring with brake cleaner and / or alcohol . Cleaner , the better .

Heat the springs damaged end , glowing red hot , shape it , water quench it .

Repeat the heat , then oil quench it .

In that^ order , the spring should be tempered and ready for use .

At least , that has worked for me . ;)
