Leaky Neutral Switch Case Fix

[davis]

Just wanted to share an idea on making the Neutral Switch Case leak-free. I got tired of cracking the (old) plastic cases from either installation or engine vibration so I cut a groove in the shifter drum shaft for a #013 (1/16" nominal) o-ring and wrapped teflon tape on the center screw threads. I haven't run with this modification, but bench tested it using kerosine without leaking. I also had some success with using rubber washers under the three mounting screw heads.

Bob was unable to post a pic of his fix. He sent it to me and asked if I'd post it, so here it is.

     Bob,
           Great job on fitting an 'o' ring to the change drum. I fitted a neutral switch just last week and within hours was taking it off again to try resealing it. Occurred to me that BS could have so easily installed a seal on the shaft.                     Brian

Thanks Brian.

If you don't want to replace the shift drum (as I am going to do this winter) the teflon tape on the longest screw that can be fit in (13mm) will slow down the leak significantly.

Brian,

I see that Bob calls it 'teflon' tape...I'm not familiar with that, so wondered what we would buy over here...PTFE?

           Hi Steve,
                          You are right, Teflon tape in the US, PTFE here, same stuff.                            Brian.
