    Default First problem with the D2....

    The Pony Carb was being a bit tempermental when I got the D2 home so I took the carb off and it had trash inside . I then cleaned all the lines,fuel tank,sediment bowl plus the carb. I discovered also a torn gasket which I need to replace. Enclosed is a picture which shows the center piece of the gasket seperated and laying to the right on the table. Also the carb numbers from the brass tag.Can anyone help with a source ?

    CYSCO,
    There are alot of sourses that you can get the gasket's from.
    Alot of guy's will prob write back with that information.
    What I ended up doing is go to napa and buy some gasket paper and make it yourself.
    Besides,there are alot things you'll need gasket paper for in the future.
    I own an compressor shop and we cut out oddball gasket's on a daily basis.
    It's certainly not rocket science.
    One word of warning, when you bolt the two carb bodies together DON'T use excessive poundage or you'll strip the thread's.
    EASY DOES IT.
    That thing is going to start right up!!!!!

    I made new gaskets for my D4,Compressor is right,sometimes the carb casting can be a bit flakey,you dont want to strip the threads.
    Good luck with it.

    Default Carb. Gasket

    I think the gasket you want is a 9B4838 so I,m sure your Cat dealer would have one.

    Default Gasket

    Thanks guys....I am not very close to a Cat dealer so I may try the gasket making route first. I have done this before and it is not to bad. I agree on the not to over tighten the screws. Learned the hard way on Holley carbs.

    If there's a John Deere dealer not too far away, you can get the gasket kit from them. It's a Zenith TU4C carb and if I can read my scribbles correctly, their number for the kit is K2067.

    The K2067 kit is a partial repair kit for about $35.
    If you just want the main gaskets the JD # is now RE528697 (runs #8 - $13)
