Hi all,

I have uploaded pics of my rusty kart onto the link below.

Basically from what I can gather, I need a jackshaft sprocket.
I have no clue what size and how to put these peices back together once I find the part. Basically I am 100% lost.

Would love it if anyone can help. Pics in link.

Cheers all!

ok. well your kart is a Yerf-dog model# 3020 its a re-called model. has some pretty bad steering issues. There was a repair kit put out. so it may have already been fixed. The clutch should be a Max-torque 20 series unless it was changed to comet some time in its life.

It would be much easier to simply buy a new driven clutch. this should do it, http://www.bmikarts.com/item/Max-Torque-Driven-20-Series---Outboard-400806-6326
(unless the clutch happens to be a comet)

Hope i helped

I am not too sure what type of TC you have there, but if you look at this link

Thanks guys! Do you know what size of jackshafy sprocket I would Need?

It does say comet on the peices I have here.

 

[YerfDog2012]

Wow those links are amazing!!!!
Is there a standard jackshaft sprocket size for this yerfdog/techmuseh kart?
Once I figure out wich one to get, I goin to search for a site that will ship to canada

 

[spyder1968]

i believe most jackshafts are 5/8ths....some are 3/4". as far as sprocket size goes....
first you need to determine what size chain you need......usually 35 or 40/41.....
then ....what size rear tires? .... and how many teeth on the axle?
from there i am sure there are plenty of people on here that could advise you on a good setup!

You say you need a jackshaft sprocket. What sprockets do you have? Give us the tooth counts of all of them. Maybe close up post a pic or two here in your thread of the engine and drivetrain so that we can see what you have

 

[cumminsbayou4x4]

[YerfDog2012]

You guys are awesome!

[YerfDog2012]

10-4! I will make that happen asap!! Thnx guys!

 

[YerfDog2012]

Hi guys, sorry the the delay in response. I have counted the teeth on the axle sprocket and its a 60 tooth sprocket.

Mainly I want to see if any of you can let me know what size of jackshaft sprocket I need to get.

Basic pics http://s1168.beta.photobucket.com/user/leafjutsu/library/

Close up pics coming soon. I really appreciate all your help!!
Sincerely,

I'm not an expert by any means, but I'm gonna guess it had 10 tooth sprocket on the jackshaft.

From your picture you have a 12 tooth sprocket.

 

[landuse]

From your picture you have a 12 tooth sprocket.

How could you tell???

I would suggest that you go for a 10 or a 12. A 10T will give you more torque, but less speed. If you are riding more offroad, I would go for a 10T.

He can't tell. Its a 10t 1/2" pitch 5/8" bore, C sprocket from the factory.

Though so. There is no sprocket visible

 

[qtband]

If he has a 5/8 jackshaft, the driven from BMI that is linked above has a 3/4 bore.

 

[YerfDog2012]

Thanks everyone!! So its looking like a 5/8, 3/4 bore 10t jackshaft sprocket eh? Man if this works I swear I wish I could buy you all lunch lol.

I know the pics aren't great. I was investigating how I was going to take of the plate on the jackshaft to install the sprocket but my shaft is beat and I might have to do some filing to be able to get this plate off.
