    Rebuild Question

    got the six speed in apart Thanks alot to Graysteal M6's Write up., and fount that the 1st/2nd syncronizer keys where sheared off.

    now with the questions.

    Replacement part list ATM:
    1st/2nd Sycronizer keys
    3rd/4th scronizer keys
    1st/2nd shift fork pad
    Isolator cup

    Now that i have it apart is there anything else i should replace?

    after second craped out the gear didn't spid down i had to grind it in. was that because of the Keys or should i replace the Friction cones for 1st and 2nd?

    Also from the ginding i find it hard to slide the 1st/2nd Synchronizer Sleeve on too the 2nd gear, from the grinding there is alittle lip on the gear teeth and the sleeve, can i take a little metal file and smooth that down??? or do i have to replace all that????


    I can post pic's later when i get home.

    Thanks in advance for all your help.

    Sounds like you're off to a good start. I would definitely replace the blocker rings while you have it apart though, it would be foolish not to since they are a wearable component. They are also relatively cheap, and you can buy them in a set for all the gears at once.

    If the synchro keys are sheared off, it will make it damn near impossible for the synchro assembly to engage a gear, since the keys push on the blocker in the first stage of synchronization. Some wear on the synchro sleeve teeth is normal, but if its too badly worn it will have to be replaced. The teeth should be in the shape of of square with a pointed top (like a house), if they are badly worn and don't resemble that shape at all, the synchro assembly should be replaced.
