    Hello

    I want to change my derby cover. Can someone tell me the name of the tool I need to take the bolts out? I know its not your standard allen wrench. Is it a hex wrench?

    I am also going to change the gasket, but was wondering if there is anything I need to be aware of before making the change. Trying to avoid leaks.

    Thanks

    It's a T27 torx head.

    When you get a set of Torx wrenchs buy a good set .Cheap ones will strip out right away and ruin the head of the bolt. Craftsman makes a pretty good set and they have a life time warranty.

    Yea, don't buy Harbor Freight Torx tools. Mac, Snap-on and Matco all have good ones.

    A good set of Torx screwdrivers are real handy to.

    Thanks All.

    Have my eyes on a set from Craftsman.

    I was told that changing a derby cover can be tricky. Looks straight forward to me.

    Is there anything I should look out for?

    Changing out the derby cover is very simple. I've even reused the same gasket when pulling it off, course that don't mean you shouldn't change it.

    tighten the bolts up evenly, I had a friend who tightened one all the way and then did the next one and it leaked, he took it back off and set it on the bench and you can see it is warped, Todd

    I have a few tools from Harbor Freight to and while most are fairly good the Torx 1/4 drive set sucked. They all rounded out at their corners. My Mac tool 3/8 drive set works good. The thing about Harbor Freight is all their tools are made mostly in China. Most all of my hand tools and roll-a-round tool chest are Mac Tools. I was a MAC Tool distributor for 8 years.

    When it comes to hand tools I have found that MAC tool are at the top..(Cost and Quality) I am more or less a "shade tree",but, I have found poor quality tools cost more in the long run than the cheap ones. I call the cheap one "throw away tools" and usually in the middle of the job when they break down and ruin the project!!!!

    Don't tilt the bike, it must be straight up or you'll get leaks.

    Any set of tools that have a "lifetime warranty" would be good enough for a DIY guy, like Craftsman. Mac &Snap-on if you do it for a living.

    forgot to say, get a brick or piece of wood to place under the kickstand to level the bike if you don't have a better way to keep it straight.

    A good torque wrench is also recommended. And like previously stated, tighten evenly.

    Always tighten evenly, in steps on a star pattern.

    check manual but I'm guessing no more than 10 ft pounds
    get a torque wrench...

    With some torque wrench's 10 pounds won't be real accurate so a inch pound torque wrench for lower values might be more accurate.

    12 inch pounds - 1 foot pound

    believe it or not I've been asked that question...
