    You'll probably be ok Unless your machine has a 5000 transmission.


    My new beer holder spilled some on the trails - in it's hair and down it's throat.
    Joe Camel never does that.

    I think it’s a 7000 but not sure. Any way to tell. All of the info on it is gone.

    I think the most common engine out of the factory was a 295 or 297 single cyl JLO rated about 18hp. The primary clutch may or may not work. There were at least 2 different shaft sizes in the 2 strokes and various belt widths. If you are looking at inexpensive repower using what you have that is understandable. In my opinion, a 4 stroke will make for a much better trail machine, but probably at a much higher cost. As ArgoJim stated, the Baker-Hill 5000 was a weaker trans, but with a B-H 7000 or t-20 any motor within reason will work.

    Aside from transmission limitations, the biggest question is: How do you plan on using the machine?

    looks like a 7000. From what i understand the 5000 doesn't have reverse and that looks just like my 7000. looks like you have some spring issues though

    What's going on with that convertor? Look at the trans tag it should be stamped.
    Also outer bearing diameter is either 5/8 or 7/8.
