Gear Shift Bolt
« on: May 21, 2016, 09:15:38 pm »
After hearing all the problems with the bolt and getting the bike ready for my up and coming Europe trip i thought i would change it and keep the old one in the tool roll. so i got a new one from triumph this week the part number has been superseeded to a new number (part number T3331614)  it now has a cut in the center to let grease to sit there ha ha if only triumph would put some in it, mine was as dry as a bone i decided to remove all the locktight from the new bolt and clean the old stuff from the frame as if it does break i want to be able to remer now.ove it. as a far as i can see if it does come lose it will not come out as it will hit the foot plate now its much smoother to change. i also fitted my stebel horn and checked my rad hose clips all good and tight so I'm a bit happier now

Thanks for sharing,  knowing these can fail,  my dealership did remove and re-grease mine on its last service (free of charge ),  if this part has indeed been `modified' to retain the grease ,  then next time,  I'll get them to replace it with this part .
   Just make's me wonder though,  if it is  a `redesigned  / modified' part due to failures,  surely  Triumph should  be having these replaced at the dealerships and does this mean the `modified ' bolt is now being fitted to the new Bikes of the production line ?    :187:

I've prepared in readiness too  :002:

Drilled out pivot bolts on both pedals...





Now I'm all ready for the next drop...!

yes that a good mod but as a new bolt is only about £5.00 i just got a new one and kept the old one as spare, but cleaning the locktight off the bolt and coppersliping the thread is the way to go as the amout of it put on would make hard to get it out.

Skiprat had the original idea but he threaded the pivot bolt too.

Agree with you on the Threadlock, hopefully I should know fairly quickly if they start working loose  :002:

I have a spare Allen bolt in the tool kit - just in case.

That looks like an effective and relatively simple Mod  :047:

With there being no shoulder to the end of the thread where it meets the main body
( as on the original part ), it should be stronger and less prone to breaking off  :028:

It surprised me when the 8mm drill cut through both pivot bolts like they were made of cheese, no wonder they break off so easily.

Interesting to hear that they have changed the design of that bolt and nice to see another mod/way of dealing with a possible failure. Maybe that 'all the way through' bolt would just bend rather than snap? Or could it end up snapping off the lower section of the aluminium casting?
Maybe that's why Triumph used this design of bolt in the first place, I dunno??
