Hilliard Extreme-Duty Centrifugal Clutch - 3/4in. Bore, 12 Tooth, 35 Chain Size
Hilliard Extreme-Duty Centrifugal Clutch
This clutch is easy to install. The directions are clear with good diagrams. The new clutch made a notable difference in the pick-up and top speed of the go kart. I purchased the clutch because it handles heat build up well which is needed for extended clutch life when used by novice riders or on short courses that require a lot of slower speeds.

The new clutch was easy to order and install. Works great and made all the difference possible. Got it in 3 days and price was great too.

Best Clutch for General Use
This is by far the best clutch for the money. I have used this clutch on many Go kart and Mini Bike applications. If installed with the proper gear ratio, heat is no longer a problem, as with older or cheaper versions of this product. Also this clutch, is made in the USA!!!

Bought this for my mini bike rebuild project. Ordered with the standard springs (2300rpm engagement) and ultimately bought three other varying spring sets. I chose the red springs for general use (1200rpm engagement), works great, spring changes are very simple. No special tools required.

I acquired a used go-cart frame less the engine. I purchased a new engine on ebay and everything else from Norhern. This part worked flawlessly and installed in minutes.

Nice Heavy Duty Clutch
I'm giving this 5 stars - Running it on a homemade yard kart with a 6.5HP engine ( haven't used long term yet so i can't positively vouch for durability yet) This is not my first clutch - it seems very heavy duty compared to others i have used. Runs very well and strongly!
- i'm surprised by the negative reviews. 1 thing: a reviewer above was angry that it failed when only being run 3/4 speed - you need to know that "partial throttle" is bad for any centrifugal clutch! If the engine is not spinning fast enough the clutch will slip, get too hot and fail.
Be sure you read the directions for use and especially OILING! You can't just squirt oil into the thing! If you oil the clutch surface it will ruin the clutch - only oil the bronze bushing!

Noisy grabby clutch
I put a 6.5 HP clone engine on the grandkids' minibike and fitted this clutch. Followed all the instructions about lubrication. Within minutes, it was making nasty noises - like the chain was catching on something. Took off all the chainguards, checked alignment, tension - all OK. It's the clutch. Don't know what's going on inside - maybe the shoes are sticking as they engage? The noise only happens as you accelerate - stops once the clutch is fully engaged. But it makes an awful racket getting there. I just don't like the design of this clutch, with the c-shaped return springs. Bought a Max-Torque - smooth, quiet and works great.

This clutch did not last 30 min. of light use. We ran the go-cart at 3/4 speed 1 block, stop and change drivers, drive 1 block, 3-5 times and the clutch seized up.

The sprocket I ordered from Northern was exactly what I needed. I searched the internet for the right part until I found this site. It was very helpful in helping me pick just the right part.
