    I was looking for an easy way to mount a DIY jack shaft.
    This is what I ended up with.

    I see I am not the only one that put my engine on the centerline on the OCC. That jack shaft set up looks real similar to mine. I used Chromoly tubing and the 5/8 x 1 3/8 bearings.

    Retmachinist,
    Just wondering why you didn't go multi speed. That was the object of my project. I monitor all your posts. You do some good work, but then I'm used to being around machinist and toolies!

    Bandito,
    I bought the bearings and shaft on line ($40), the bearing sleeve is 1-1/4" black iron. The pedels freewheel. The motor also freewheels with the clutch engaged, because I was going to pull start only. Now I think I'll weld the motor freewheel so I can also bump start also.

    I have an old 3 wheeler and think the jackshaft idea will suffice but not sure what I need or where to get it. Can anyone help.

    Sheepdog31,
    FYI, I know your new, note the date of the thread, upper left above the user name. Original post was OCT, 09. No big deal, normally oldies are for info, you may not get a reply, just so you know. Still good info.

    Wow that is not what I had envisioned. I have built a motorized 3 wheeler but didn't look anythin like that.
    What kind of speed are you looking for, to figure the gear ratio. How many teeth do you have on the rear sprocket. After my last PM to you I wasn't sure what you had decided. What is the circumfrence of the rear wheels?

    Sorry sheepdog,
    Guess I was talking to the wrong person. The kit your looking at is the most popular with a good track record.

    I have a bunch of jack shaft parts sitting around doing nothing. I have a complete New 3/4" kit (keyed shaft and keys,hangers,bearings,sprockets), I also have some extra freewheels and freewheel adapters.
    PM me if your interested need them.
    Cheers

    I got a shifter kit from sickbikeparts.com and it came with directions. attached is the photo of the remodeled or welded change to this 3 wheeler and I have received the shifter kit with a jack shaft and free wheeler included but however the standard shift kit did not include the bearings and races for the new bottom rack crank set. I had to spend another 25 bucks for that item. a little dissappointed in that. I have the jack shaft installed and waiting on the bearings and races. also have the motor mounted. Because of this bikes unusual design I was able to mount the jack shaft on the second post and not on the first as a rear motor mount, got lucky there.
