hi all -i am buying a chain and sprocket kit from ebay for att600 -ihave a speed 4 -seller tells me almost all parts are interchangable between the 2 bikes and the kit is perfect for a speed 4 -is this true- dont want a mix up thanks again ..mike...

The parts are interchangable however...

The older TT600's came with a 14 tooth front and 42 tooth rear sprocket. (3:1 drive ratio). Triumph later updated them to 15 tooth front and 45 tooth rear (still 3:1) to reduce wear on the chain slider/guide. Id go with the 15/45 if possible. FYI 15/45 needs a 108 link chain.

not sure who you were going to use on ebay but i went with lm spares in hereford.
they were doing a d.i.d x ring gold c&s set for £100 ish delivered. i gave them a ring and they changed my order to a 15 front and 47 rear sprocket. good people.

def don't go lower than 15/45 mind. you'll be ordering a new chain rub strip faster than you can blink....!

Hi,
I was thinking about doing this job over the winter, I've got a 2001 TT. How long should it take and is it a hard job ?

GNTurbo6 · 08-27-2009, 05:16 PM

Took me a couple hours the first time I did but I could probably get it done in 30 minutes now.

are we talking chain n sprocks or chain rub strip???

Lads,
It's both chain and sprocket,I plan to do this over the winter as a wee project.

Cheers

it's not too tough a job- rear sprocket is a case of undoing the bolts, chucking the old sprock away and installing the new one. i left the bike on the side stand whilst slacking them off.

front sprocket can be a bit of a pain. my chain had snapped so i wasn't intially able to use the old chain and stick it in gear to lock the sprocket.

eventually i lock wired the old chain on, put the bike with the front wheel against a wall, stuck it in gear and got my wife to sit on it with her foot down on the rear brake. a large breaker bar helped too.

as i didn't have to cut the old chain off i skipped that bit. but if you do have to break the chain grinding off the soft rivets or angle grinding it is def the way forward. many a chain tool has been broken trying to punch out the rivets.

feed the new chain through, carefully install the o rings, lube 'em good, press on the plate...not too much or it'll bind. do it slowly and keep testing it's movement.

(chain tools are great for pressing it on or you can use mole grips and a small socket over the pins.)

then use the other attachment on the chain tool too 'mushroom' over the rivets. you can use a punch too round them over too.

in the absence of both i have pushed on the plate and very gingerly ridden to my local shop and had them mushroom the pins over.

hope this helps.

Spring the 10 bucks for the rivet style link. If you don't have a tool, find someone who does and have them help you. In fact, the $60 tool is far cheaper than the plastic that gets chewed up when the chain lets go. Even if it doesn't chew up the plastic, it will leave you waiting by the roadside when that link pops. I personally like the rivet links because they afford me a false sense of security.

Now links don't tend to explode or let go with any regularity, but over time, mine have seemed to do just that. Minibikes, dirtbikes, go karts, street bikes, riding tractors... all the same.

Of course, my TT doesn't have a guard on it which might be the bigger issue with destroyed plastic.

never remove your front sprocket with the bike in gear. the last thing you want to do is bang the transmission around and break or bend any parts(most likely shift arms). leave the old chain in place and stand on the rear brake. If you use an impact it will come right off.
