    Has anyone done their own underdrive pulley install?

    Anything I should be made aware of?

    Anyone feel it wasn't worth doing themselves?

    I did the cam and torque tubes install last year on my 2011 hammer, it wasn't easy but wasn't awful either.

    I called a local dealer and they'd charge $250 and id have to trailer it about 1.5 hours to get it done or I can just do it myself.

    Leaning at doing it myself but just making sure I'm not going to deeply regret it lol.

    Thanks in advance.

    If you can turn a wrench, not hard. Have new exhaust gaskets. Soak the exhaust nuts a day before you start. Torque is 180 on the nut. Not all 1/2" TW go that high. I pulled the timing cover and locked the crank. There are other methods. People use impacts, I used a breaker bar because I didn't want the hammering on the trans. Wait until your done to have that celebratory brewski.

    biggest tip .... the stock pulley nut is held on with red locktite. use a torch and heat that thing up before you try to remove it and it will come off much easier. especially if you have an impact with a 1 & 7/8 socket (BIG f**ker)

    They
    HF does have a new tool line ..... Icon.
    looks decent quality. Lifetime warranty. Not cheap either. Yes pulley is doable with right tools and know how. Just have to know how. @PreachSF has best advice yet. Take it ..... after all they make the pulley !!

    After you get the bolt out of it make sure you use some brake cleaner and a right angle pick to clean all the threads before assymbly. Never hurts to run the bolt all the way in the cleaned threads once with just your fingers. Any resistance means more cleaning.
    It's been a while since I did mine, but I think I used a specific sized drift to lock up the transmission before removal(May have been when I dd the clutch...). Don't want to hurt the trans gears.

    It's an expensive socket for limited use. Especially in mm for those in the USA. Try to find a friend of a friend who's a heavy duty mechanic to try and borrow one.

    Exhaust was a c-word. Lots of penetrant and patience on the studs. Would hate to break those off. Tape off the fins on the heads/cylinders so you don't beat them up getting the headers off/on. I used blue masking tape. The big nut was interesting. Impact ended up making the job easy. After getting that big old nut back on take it easy on the small bolts holding the lock plate in place, easy to over tighten them. Your gonna love the pulley, maybe my favorite mod. Cams are right up there too. Have fun!

    Thanks! This was helpful and encouraging.
    I'm getting excited to feel the difference the pulley brings.

    The exhaust is the worst part of the job.I used a piece of wood about 1/2 by 1and 1/2 by 4 inches long I put between a tooth on the sprocket and the swingarm to keep it from turning when I loosened and tightened the big nut.As been previously mentioned use a bit of heat on the nut first to soften up the loctite.It might be a good idea to put a bit of lube on the splines before you put the new pulley on.Splines have more of a tendency to wear if dry.
