    77 Kawasaki z400 timing advancer

    Hi,
    I have had a small go at getting this off and it is not budging. Is the timing advance bolt left hand thread. The bolt is marked with an ĎLí but the simple manual that I have does not state direction and I canít find anything on the net about it. Thanks in advance. Deano.

    Re: 77 Kawasaki z400 timing advancer

    I have a shop manual for a KZ400 & 440's. Which I just read several times about the advancer removal and install but says nothing about left handed threads.

    I've have worked on 100's of these back in the day but don't remember if that bold it left handed threads. But the "L" on the bolt makes me thing it's left handed threads.

    If you have a impact wrench I'd try it a couple of hits to the left if it didn't loosen then give a couple of hits to the right.

    Good luck!

    It's a "7" not an L

    Hardness of 7

    Loosen as a normal bolt. A 3/8" impact will make it easier. Hold the larger and loosen the outer smaller one.

    ooooooooooooo

    I have a shop manual... I just looked again and it sure looks like a L and not a 7... but being RHF seems right!

    I've been racking my brain all day thinking about this. Called a couple of old timers like myself how worked on these back in the day. None of us could remember the bolt being LHF and we felt it is was the manual would state that.

    Plus with the engine running counter clockwise what would be the purpose of it being LHF. None of us remembered the "L" / "7" being on the bolt.

    Mystery solved... I'll sleep better tonight thanks to you Pete...

    not an impact gun. An impact driver. Like a big screw driver with a sockett on the end
    You hit the top with a hammer while holding the handle to turn it in the direction you want to go.
    NAPA and others will have one.

    No, a 3/8Ē impact gun. I use a DeWalt cordless to do stuff like that.

    My mistake. But it must really be on there if you need that much torque. Or is it for the speed

    It just shocks it off. It's the only way to get JIS Phillips head screws out in carbs too. :-)

    It's either JIS or Phillips, not both. The 17mm is just a slotted nut to turn the engine over.

    I got it off fellas. Just had to modify a cheapo spanner so the 13 socket would go on properly.

    Now I am into the clutch. Thanks again.

    Re: 77 Kawasaki z400 timing advancer

    Glad you got the bolt off!!

    I have one I've brought back to life... its 1974 KZ400 and hadn't ran since 1978 only has 2,300 miles.

    The carbs were a REAL mess, got them all taken care of. The disc brake was a total mess, had to replace the master cylinder, brake lines and all the seals in the caliper. Couldn't get fluid to pass through the brake lines no matter what I tried

    Next new petcock, tires/tubes, battery, oil/filter. After getting it running I discovered the intake booths needed replacing which wasn't a surprised... replaced them & sync the carbs.

    Then adjusted the valves and cam chain did a little test run with the gas bottle hanging on the handlebars and it ran like a new one.

    Only think to complete is sealing the inside of the tank!

    FYI... if you end up having to replace the brake lines this might help!
    I couldn't find any for a KZ400 but I purchase a line kit for a Z1. It comes with the upper and lower rubber hoses and the steel line. The steel line won't fit (per-bent for Z1) but the 2 rubber hoses worked great.
    The steel line should be good, may need to be cleaned out.
    The upper hose Z1 hose is about 3 inches longer but looks and worked fine... the lower hose is about 1 1/2 inches longer and caused no issues either.

    Good luck... PM me if you have any questions or I can help!

    Re: 77 Kawasaki z400 timing advancer

    Thatís really good information Wayne.

    I have cleaned and bench synced the carbs. Had to replace the diaphragms. They were shot.

    The intake boots should be here any day. They had very minor surface cracks on them. Had a bit of trouble getting them off but got there eventually.

    The front brake was quite bad. I gave that a good clean and have replacement seals, just got to put it together.

    The master cylinder is seized. Iíve got a kit for it and have
    some special circlip pliers but still have to modify them to get that apart.

    Iím just going through the clutch at the moment. Ordered a couple of friction plates.

    The tank is pretty clean but I will put some cleaner through it.

    So, I intend to get it started first, then Iíll complete the brakes and forks. Once she is a runner, Iíll tackle the cosmetics.

    Thanks for the info on the brake lines, Iíll have to do something there.
    Thanks.
    Deano.

    Is that because of the climate there Pete?

    Maybe I should have ordered an extra set ha ha.

    Iím in Australia. Pretty warm here.

    In a milder climate they "Might" last three years.

    Buy an extra set, seal them in like three ZipLocs and keep them under the bed in the dark.

    My pleasure on the lines.

    You've got a really nice looking bike and something worth restoring, looks really nice for a 42 year old bike

    KWICK is right on the intake booths... we had the same issue in southwest Florida... same issue with ALL models of Kawasaki using rubber intake booths... we made a ton of money replacing them.

    The sad part first time replacement ones many of the screws broke off or the Philips head would strip because of the salt air. We'd use "never seize" and allen bolts so next time that wouldn't happen... trust me there would be a next time.

    Keep up the good work...
