Gear shift rod repair kit
Posted: 20 Apr 2011, 18:51
Blatant plug warning!
Here's something that I am testing before releasing to you good people (spot the difference!)

Most of the damage to the original nylon tips seems to be due to degredation of the nylon due to exposure to oil-based grease, causing it to soften and then tear/fracture at age-related cracks in the mouldings.
Once I'm happy with the durability of the repair and there are some clear instructions for installation, they will be available as a DIY kit.
You will need to remove the lever from the vehicle but fitting is genuinely easy (you don't need any special tools, not even a bench vice) but you will need to allow setting time for the epoxy that is necessary to "pot" the repairs firmly onto the tips before fitting. Strip out 20 mins, degrease and glue the same, leave overnight and fit in the morning. Faff about for an hour to get the shift right and then
Needless to say, the difference in shift quality is remarkable! I also applied some bitumen sound deadening pad offcuts to the gate box, it nearly stops the clanging and clonking, much more refined.
I'm also using Rocol MX22 silicone grease as an alternative as it doesn't attack plastic or rubber and has no solvent so won't wash off. Should be good on the lever ball as a replacement for polygrease too.
These kits will obviously fit 4-speed levers as well, 5-speed kit now in development and will be tested very soon.
Thanks to Aidan for the dimesions, loan of the spare shift rod for testing and for reminding me repeatedly to get on and develop this original concept
