How to fit a genuine Triumph front mudguard extension.
« on: May 11, 2016, 06:07:26 pm »
At the risk of telling you  how to suck eggs, I hope someone finds the following  useful: The mudguard extension arrived through the post together with four plastic rivets and zero instructions. I found the Triumph official, "full fitting instructions" on line which talked about the need for a plastic rivet gun (cos we've all got one of those in our tool boxes haven't we?) and nothing else useful at all. So this is what I did...

Remove front mudguard by undoing the lower Allen bolt only, of the two which pass through the mudguard in front of the fork leg on both sides of the bike (don't try to move the upper bolt it's likely to be rusty and only serves to hold the shiny front bit of the mudguard onto the matt black rear section.) I then removed the single Allen bolt behind both fork legs. this allows the mudguard to be removed forwards.

Now offer up the extension and when you are happy it's in the right position with minimal gaps between it ,and the main bit, mark where the holes are to be drilled (5.5mm drill bit) using typist's corrector fluid. 
Drill the holes by resting the mudguard on a piece of wood so that the drill bit doesn't shoot through uncontrollably once the hole has been made.
I then mixed up 2 pack epoxy resin and glued the extension into position. (Can't do any harm and it'll prevent any play between both parts should your  riveting be less than super tight.)
Now the most important bit...
In the absence of any specialist riveting tackle, just pass the long " male " half of the rivet though from the outside of the mudguard and then push  the female half on  until it will go no further. Place the mudguard with the head of the male half of the rivet  flat against a block of wood and hold it steady. ( a second pair of hands comes in very handy here) Now you want a small metal tube , long enough to clear the other (pointy) end of the rivet and with a diameter small enough to sit against the rim of the female rivet half. I used a 1/4 inch drive 6mm extension socket which was perfect. With a soft faced hammer,  tap on the end of your tube (socket or whatever) until you've driven the inner (female) half of the rivet up nice and tight with no play in the joint. Repeat this for the other 3 rivets.  I found an extension piece attached to the socket gave me more control and accuracy when I was doing the two side rivets.
You may now want to clean all those little places which you can't get at so easily when the mudguard is attached.
Replacing mudguard is easy , just remember not to do it up too tightly , it's only plastic and may crack if you're a bit over enthusiastic.

Thanks Paul, My extension is in the incoming section of the garage. I'll review your coaching before installation.

Cheers

Studley,

If you haven't done the job yet, my suggestion would be to get the plastic riveting tool.  They are probably available at many auto supply stores but I got mine at Princess Auto for about $30.00.  It is supplied with a small assortment of plastic rivets and is a good quality tool.  (I haven't had that opinion of everything PAL sells.)

If you're not a "tools guy" or simply don't want to spend the money, then Paul's method (he seems quite resourceful) may be a reasonable alternative.  With the riveter, you don't have to remove the front mudguard and the setting of the rivets is easy and should contribute to a quick, good quality installation.

My thoughts,

Theo

Hey Theo, thanks as well. I did two fenda extenda's on my Explorers and used ABS glue / cement. Not sure what application method I will go with on the Trophy but likely ABS cement. If I feel I can get the components to align for that one chance you get with that stuff. :>) You could say it holds..DAMHIK.
