Bendix question...centrifugal weights... what is their mechanical function

[Freakie]

I have pulled more than a few bendixes and repaired them with bits and pieces of others over many years...I understand 99 % of how the bendix does its job, but I cant fathom how the centrifugal weights with that crappy liitle spring helps it to do its job.....I am tempted to delete that whole mess and try it, but maybe someone out there can give me an engineers perspective.

tks peeps

They had to add weight to the screw to make the gear react to the starter spinning up. There is nothing else that actuates the gear.

The spring in there is typically the weakest link in the bendix....I want to put 2 garter springs in as a backup in case one snaps......any thoughts on that...tks v much

Thank you for an intriguing reply JC...I really appreciate it. I am trying to visualize how those weights move outwards when the starter is spinning up to the point where they touch the barrel that limits them flying apart, which must be the point at which something magic happens, much like you have explained , so I am going to try 2 springs and see how things play out with this config....will report back how the meshing part is better or worse.

The garter springs are wear items, its easy to see if you look at them. Just replace it every season.

Our dealer here would only sell the whole bendix....no garter springs only. However I put a second spring in and have tested it now a number of times and engagement is perfect every time an gear retracts perfectly so this is a back up in case the one breaks.....I think it's good insurance

You can rob a spring off of a seal of about the same size, check your local parts house, Polaris uses the same bendix and some individual parts are available from them but not the spring.......................

Thats exactly what I did....i took 2 from Yami main bearing oil seals I had ..They are slightly thinner than the OEM but the same diameter so that why I wanted to double up.
