Thank you for your purchase of the best Sportsman clutch on the market, The Red Devil Flame!
Assembly
·
Check the engine's
crankshaft for smoothness and cleanliness. Remove all dirt, rust and burrs.
·
Install the clutch, sprocket towards engine (unless you are
using our outboard 9-10 tooth kit or are mounting it outboard due to room
limitations), checking to make sure the clutch does not extend over the end of
the crankshaft
·
You will only have
three pieces to install, the drum/sprocket assembly, center keyed washer, and the drive hub
·
The drum assembly
consists of drum, inner race, sprocket, and washers
·
The drive hub
assembly consists of hub, shoes, springs, and red finger guard. Do not operate the clutch without this
guard!
·
Slide the
drum/sprocket assembly onto the crank, followed by the center keyed washer, then the drive hub assembly (If mounting
outboard install the drive hub assembly first, center keyed washer, then the drum assembly)
·
Install the clutch mounting bolt
·
You’re Done ! It’s that easy
Adjustment
Clutch
engagement needs to be set 200-400rpm above peak torque for the engine. Your
clutch comes preset for the class and engine specified. Every engine has a
different torque curve, so sometimes adjustment is necessary for peak
performance. If you don't know the peak torque
rpm and your clutch is not accelerating like you feel it should there are many
different spring combinations available. One of the largest issues we see are clutches with engagement higher than peak torque which
causes slippage, heat, and costly repair. Today’s OHV engines use torque at low
rpm to accelerate, use the torque your engine has.
Important things to check for
performance
Shoe wear: Every couple of race weekends,
inspect the shoes for cracks, overheating, and glazing. Using 80 grit sandpaper
scuff the shoes to remove any glaze. They do not have to be perfectly shiny.
Spray off the shoes with compressed air and then clean with wd40 and a rag.
Drum wear: When inspecting the shoes, pay
attention to the drum as well to see if we are beginning to glaze over. Scuff
with 80 grit sandpaper as well, and clean in the same way as the shoes.
Inner Race: The inner race for the sprocket
is made from heat treated, hardened steel. Inspect for
any cracks or wear. Clean with WD40 and a rag.
Sprockets
Clutch drive
sprockets are taken very seriously in the design of our clutches. We use only
SMC brand sprockets. They are heat treated, precision
machined, and cost the same as more inferior products. Sprockets should be
cleaned with brake cleaner, dried, then lubricated with High Temp Red Bearing
Grease. Grease is for bearings, Vaseline is for skin care. We will not warranty in any way, any
clutch that is using the WMS or other cheap knock off sprockets. Do yourself a
favor and buy good drive sprockets, whether it’s from us or another supplier.
Cleaning
We recommend cleaning
the clutch after every race weekend. Remove from the kart, spray off any dust
or loose material with compressed air. Spray the entire clutch assembly, drum
included, with WD40 and let the clutch soak for a few moments. This does two
things; It allows the wd40 to loosen any grime and
dirt on the parts, and it allows the parts to maintain their correct coefficient
of friction and wear. DO NOT use Brake Cleaner, carb cleaner, or any other
harsh degreasers; This will strip any oils from the
parts and cause a very aggressive engagement and accelerate wear dramatically. We
will not warranty in any way, any clutch that is cleaned with harsh chemicals.
