    Hi,

    I went to change the piston and bearing in my '17 tc125 today and after a bit of inspection i think there is excessive play in the big end bearing. I can't find any tolerance specs online nor can i find a repair/ workshop manual. Does anyone know where i could get one from?
    The rod rocks side to side 1.4mm (measured at the small end), the gap between the side of the rod and crank is 0.64 mm and there doesn't appear to be any vertical or twisting movement of the rod.
    This all seems a bit sloppy to me.

    Measure between the thrust washer and the rod. Seems like most small bore engines should have about 14 thousandths. 25 does seem a bit much. But I am not familiar with these newer bikes. The top has to be able to allow the piston "float' slightly as it moves through its stroke in the bore.

    thanks for your reply. Yes that was where i measured- between the thrust washer and rod. 25 thou" / 0.64mm is the gap.

    Not a big deal most all cranks have at least 19+ thou,
    Most important dimension is total width of crank shaft to the main bearings.
    This amount of free play is critical.
    Any up and down movement on the rod is no good.
    Top rod wiggle is ok even new they have it.

    As per the shop manual, axial play of lower connecting rod bearing, .017 to .0295
