    Had some bad luck with my tt600 coz one spark plug was buggered and sheared off in the head. Ive tried lots of common things to remove it but it must be melted to the head coz it even snapped the easy out tool trying to remove it!.
    So i need to remove the head but cant find any info on how to go about it.
    Has anyone here removed a tt600 head?
    Can anyone offer me any advice please?

    Yo, have you any pals/aquaintances, maybe members on here who have a manual.
    Is there a manual on ebay etc etc,
    Manual to download online? There are a lot of pdf ones these days for around a £5 I would have thought the bike is old enuff to get one. I do autojumbles, they are good source.
    You prob thought of all these already but there yer go. Not worked on one myself :frown:

    I have just done my 955 head with the engine in the frame, its not difficult and can be done without a manual providing you have a little mechanical knowledge and aptitude.
    While the 600 is a slightly different engine, I personally would have no problem tackling it. Do you feel competent enough to have a go?

    Hi
    Ill try again.. I did make a post two days ago but it disappeared..
    Remember this is just a general overview based on my own experience, I have never worked on your particular engine so allow for that.
    Obviously first remove battery, tank, seat, air-box and any plastic that prevents access to the engine.
    Remove throttle body from engine and hang out of the way with a cable tie. Leave throttle cable on.
    Remove RH engine crankcase cover
    Remove rocker box cover.
    Remove top radiator hose and radiator, if oil cooler is attached to rad then split and leave oil cooler attached to pipes but hanging under engine.
    Remove exhaust down pipes.

    Important now, find the cam timing marks, there will be marks on the crank end that line up when the LH cylinder is at TDC, this will also bring lines into play on the cam wheels. The 955 has horizontal lines on the cam wheels when the crank marks line up. Once you have this position established tipex the marks for clarity.. from here on in DO NOT turn the crank. you may with to photograph these marks with your phone for future reference
    Remove cam chain tensioner, careful, it has spring tension behind it.
    Now remove cam bearing shells and fish cams out from under the chain, hold the chain up with some old wire or string to stop it falling into the bottom.
    Once cams are off you can unbolt the head. on the 955 you need to lift the head about ten mill to allow you to wriggle the chain slippers out, you will need the slippers out because you dont have room to remove the head with them in (unless engine is out)
    Remember to slacken the head bolts in a sequence that starts on the outer ones and ends on the innermost always going to the farthest away bolt next, and a little at a time to prevent the head warping.
    Thats it really, head off. keep something over the exposed parts to prevent anything falling into the engine, go work on the head, buy a new head gasket, renew the cam chain (I would) and give the mating surface a good clean.

    Hope that helps

    Martin

    It is easy and logical. Basic rules for any engine really. One thing with the Triumph though, wet liners... so once the head is unbolted dont turn the crank at all as this can disturb the liners and cause a leak.. If you dont disturb them they will be ok.

    Ok thats something i didnt know.
    Im currently close to lifting off the head but i have a problem with a head bolt that wont budge. Its snapped two tools so far and its the outside heah bolt closest to the front. Its exposed to the elements but its the threads that are stuck. Need a blow torch to heat block up to see if that works

    NO NO NO not a blow torch please... apply loads of WD40 or similar.. Give bolt a good solid blow from above with a drift and heavy hammer, tap your socket on and try again. If it doesn't go repeat.. The shock from above stretches the threads microscopically and releases the crud.. I have NEVER had this method fail and I've done some tight ones, leave the blowtorch in the blacksmiths shop..

    I'm saying socket, 955 are cap heads so use a good socket to allen converter, but very tight yes..

    The bolt is a torx bolt like all the other head bolts but its outside. I have smacked the hell out of it from every angle and i can see the head moving slightly but the treads are stuck. There is no way of wd40 on the threads. It has broken two torx tools in half and ive only got one left! Nightmare

    I sorted it now thanks.
    I heated up the block around the bolt.
    Put mole grips on bolt head and the torx on it and it finaly went.
    VEey tight.
    Now sorting the head. Need a head gasket now

    World of Triumph.... not cheap. Well done, think about a cam chain too, mine was well shagged when I went inside..

    For the 955 they say in sequence to 20 newton meters, then again to 27 NM.. That's bloody tight.. Not really any help unless you decide to wing it without the 600 figures, must be similar..

    Update.
    Had a nightmare trying to time up the cams as when you line them up the arrow on the crank seems just past the line but if you move it 1 tooth it goes the other side of line.
    I read on net that someone else had the same issue so i fitted it where i think it was when i stripped it going by photo graphs.
    i started bike tonight.
    its got a tap now while its running.
    i ran it for 1 min and it ran fine but the tapping didnt stop!
    Back to square one!

    Bike stopped tapping and runs fine.
    I cannot work out what the tapping noise was but after stripping it down twice i decided that timing was spot on and that nothing was hitting the valves i ran the engine up and revved it to 5k and held it there and tapping slowly disapeared and i was out on it yesterday.
    Thanks for peoples help
