    specialty tools for slx780

    So i'm taking apart the 3 780's. and i'm wondering what specialty tools i'm going to need to remove cylinders and reinstall rings and pistons.
    My list so far is:
    Ring compressor
    glaze breaker(honner)
    Micrometer for pistons
    inside mic for cylinders

    For taking apart the pump and nozzle i think i need
    removal tool for the impellor
    removal tool for coupling.

    I guess i'll need an alignment tool also.
    to buy or rent?
    any help here ....thanks

    My list so far is:

    Ring compressor--i have never needed one, use wide zip ties or a small screwdriver to get the rings in.

    Glaze breaker(honner) -get a christmas tree hone, works well and hard to destroy your walls. Or find a vw repair shop and see if they will hone your cylinders. Very similar to old vw engines. My local shop charged me $10 a cylinder
    micrometer for pistons-good to have but not needed
    inside mic for cylinders-again if you are just honing --imho not needed

    for taking apart the pump and nozzle i think i need never had to do a pump so will defer to the guri
    removal tool for the impellor
    removal tool for coupling.

    I guess i'll need an alignment tool also.

    No need for ring compresser as mentioned above. Squeeze rings with one hand (ring pins properly aligned) and slide the cyl on with the other.

    Mic you really shouldn't need.

    You will need feeler gauges for ring gap and piston to cyl wall clearances.

    Hone you shouldn't need since it's very cheap to have done for you usually locally. They can also check your bores for you at the same time, so you really don't need a bore gauge either.

    Impeller removal tool- yes

    Coupler removal tool- Maybe (you can use a REALLY big adjustable wrench with a cheater bar) But the tool is nice.

    FYI: an impeller and coupler tool can be made from an old drive shaft if you have a damaged one. Guys have just heated and bent one like an "L".

    So i jammed a rag in the exhaust port and put a big ass pipe wrench on the coupler and a 3 foot cheater and she came loose easily.
    Christmas tree honer is timely.
    I'd like to hone my own cylinders since i've got about 11 to do. I'll practice on some dogs and get good at it. Then on to the keepers.
    I could use a tutorial on measuring cylinders,ring gap and when it's necessary to go oversize with pistons and rings etc. Is there one buried in this site?
    Thanks

    The online manual should have what you seek.
