According to Haynes, there is a stepped pin used to lock the cam gears when adjusting valves. Anyone know the size? It is time for the ordeal, and the dealer wants a half ton of money, so I either will go to another mechanic, or do it myself.
Thanks.

There is a company - the name I cannot recall - that has parts for the new Triumphs, not just accessories but engine and frame parts. I also think they are listed by part number so if the Haynes has that, you should be able to match it up. A hunt around this site may get you the name.
Why not order it through the dealer if you're going to do it yourself?

You can find the pins at BikeBandit.com
go to T-100 Triumph Parts, under
Service Tools, they have part numbers
and cost.

Here's a reverse engineered drawing.



I run a machine shop so it was no problem to make a pair according to the drawing. Other people have just used a grinder to make a good approximation. The important thing is to have the step and to have something close to the .236" (6mm) and .156" (4mm) dimensions.

The tool shown in the Triumph manual is shaped like an allen key. Around 3" long with the short part 1".
The design you have will work but if you drop it it may fall into the engine (ask Dazco about stuff faling in).
The L shape won't fall in.

The Triumph Part is 3 items, hence the cost:
2 pins (so you can do exhaust and intake at the same time but jeepers, you don't have to)
1 spanner thingy (incase you need to disassemble the cam gear, which you don't, or if you've let the pins slip and the cam gears 'unwind' you need the spanner to 'windup' the gear)
I felt dumb when I got the part has the pins are hardly precision made, the gear slips a bit and you need to finnese all upon reassembly - heck use the dimensions previously posted and make one from an allen key, tape along ribbon to it so you don't drop it down the enginer.

Me, too. Forgot to put that part in, so making a stepped pins is no big thing, except I am sick of making stuff when the day is over.

The tool I show was reversed engineered from the one shown in the Haynes manual. It does indeed work just fine to hold the backlash gears but your suggestion to "idiot proof" it is a good one that you should pass on to Haynes.
