Mounting A Jackshaft

[qtband]

Does this jackshaft mount use spacers between the mount and the karts mounting plate?

 

[Whitetrashrocker]

I would definitely use spacers.

What kart is it, just for giggles?

I'm working on a Dingo, but I don't remember where I got the mount from....

with the slotted holes and as thick as the steel is, I think it's a Jack shaft mount / motor mount combination.

I would be tempted to remove the original mount and weld that one in its place...but then chain tension might become an issue. Maybe cut the sides off the jackshaft plate and mount it flat under the engine?

This is my idea as of now. That way, I can adjust the torque belt distance and the chain tension.

I though the jackshaft might slide over the base mount. The old but good black and gold Dingo did indeed use spacers, a fancy “stud” (per the manual) with a hex center. Last page, part reference 23, part number 1356. I bet it might show up on the interwebz

I like it. You’re not using hockey pucks or stacking nuts on bolts.

#23, the stud, is what I need to use. I found another plate that I used instead, but if I find those studs, I can use it on the next kart.
Thanks.

 

[Whitetrashrocker]

I used these. Fit well.

I figure if you use the stand off studs, you preserve the kart's versatility according to what drive system you want. Unbolt the jackshaft and you can use a chain + centrifugal clutch and turn it into an American Express or the clone of a Rupp Dart Kart or Clark Cyclops, etc.

The only real concern then is the chain guard under the kart, if you use really small tires. Just options, options, options.

Just to follow up.
My dingo has 18" turfsavers on the rear and the "guards are about 2" off the ground. Here's a Pic from when I peeled my floor pan. You can see the guards.

Oddly satisfying photo.

I have the same guard on my Dingo--was wondering whether to cut it off or something. I need to measure the distance from the guard to the ground and then the sprocket distance to ground. There's probably not much ground clearance to be gained by cutting it off

They are there for good reason.
Another pic for proof.
I made a pan for the rear area to keep dirt and rocks out of the engine area. you can see the beating it took.

Thanks everyone for the help and ideas!
