Just Bought A 6.5HP HF Motor "HELP"

[Jasoninsane123]

ok everone i just bought my kart today as a project for me and my brother well he just went to HF and bought the 6.5hp motor and the converter does dont line up at all its off by like a inch and i don't see anyway of making it line up would it hurt it being off a inch i think it will but would like info about it and the shaft on the motor is 2 1/4 "Please Help"



P.S heres a pic with the old motor on it

Off by an inch- what- sideways? No, you definately don't want to run it that far out of alignment. Suppose you bolt the engine on, and hit us with 3 or 4 good pics from different angles.
You may have to adjust your jackshaft positioning, or engine mount.

What was wrong with the tecumseh on it?

Jason, on Yerf-Dog engines these had a spacer which was approx 3/4" wide by 3/4" bore, the shaft on these engines Yerf-Dog ordered had longer shafts to fully accommodate these torque converters. You'll need a 3/4" spacer to move the backplate out on the shaft, the back plate will go on fully and reveal only about 1/4" remaining on the shaft to put the hub/main section of your drive clutch on. That 1/4" is just fine for supporting the remainder of the section because unlike standard chain drive clutches, this hub is a solid piece, the only thing you'll need at this point is a longer 5/16 fine thread bolt large washer and lock washer to hold this together.

so its safe putting the hub/main on the motor shaft if only 1/4 of it is showing to put the rest of the driver on it i was just kinda scared of it breaking snice it was only 1/4 of it was on the motor shaft

Its well made... don't worry about that hub.

hehe i think its alittle less then 1/4 just don't want that crap spinning at 3000rpms and break

Considering it is this way on several thousand karts, because only Yerf-Dog ordered these longer shaft engines from what I can tell, you should be fine.

you could always make your own mounts are re-rig everything if all else fails!

got the kart running but when i give it gas it jerks really bad once its moving its fine just when its not....anyone got a answer for this problem o and a other thing the spring in the drive where alittle streched and once the the kart is running it moves alittle

It is fairly common for karts with torque converters to creep a little bit when idling. As far as the jerking goes, that mainly means your clutch is not clean enough.

well i tryed it before i hooked the throttle up to see if it will move it did fine but then i dropped the dang drive and had to put it back together feel like a dumbass i think it screwed one of the springs up and now its causing the shoe to open sooner then its suppose to i will still order the springs from you and clean the converter to see if it will fix the jerking


P.S i think its the springs causing it to open sooner and making it move when i start it "if im wrong please correct me"
