Red and Green Clutch Springs

[jpswift1]

I hear a lot of talk about red and green clutch springs. I was just wondering which one would give me more low end torque. I have a 694cc flat twin 18HP Briggs in my Hustler BIGFOOT. It is geared down much lower compared to a standard Hustler beacause the BIGFOOT has 26" tires from the factory. I am getting the machine back together and I was wondering if it will have enough power to get up big hills and deep mud. If anyone thinks that it would be better to put a clutch spring that gives me more torque I might do that while I am reassembling the machine. Any input would be appreciated.

red and green clutch springs

I was re-reading some postings on Route 6x6 about a guy who put the red clutch spring in his Max IV. He estimated that changing from the green clutch spring to the red clutch spring, raised his engine rpm,s to around 2,200.
In fact, it was loud enough after he changed from the green spring to the red, that he was considering changing back to the green spring for duck hunting, because the red spring made the motor rev up more, make more noise ,and scare away the ducks.

the red spring is not going to make the engine rev more, it keeps the secondary clutch in low gear longer, wich gives you more low end power for going up hills and going through thick mud.

The paint on my clutch spring on my Hustler is all off of it, so I really cant tell what color it was. Do you guys know if I can get a red clutch spring from RI and is it easy to change?

red and green clutch springs

I called Recreatives on friday and they do have the red springs in stock. I talked to a tech on the phone about how hard it was to install the red spring if I decided to buy one. This is what he told me :
1: first you have loosen your motor stand and host the motor out.
2: I think he told me you need to remove 4-6 transission bolts that hold it in place, and then tilt the transmission to remove the spring.
3: you also need a special spring removal tool, other wise, when you loosen the bolt that holds on the spring, it will shoot out!

This is not a hard job, I would assume, for some one with good mechanical skills

I am in the middle of just putting my Hustler back together since I removed every nut and bolt on it for restoration, so I think this would be a good time to do the clutch spring. I have done just about everything when it comes to 6 wheelers except I havent messed with the insides of clutches. It doesnt seem too bad though. Thanks for the help!

Green to red clutch springs

I was just wondering how much more low end power you get when you change from one spring to another?

On both the Hustler and the Max it's easier to take the driven side Torque Converter off with the trans out of the machine. Typically the CVT is rusted to the trans shaft.
Suggested removal method:
1. Remove trans from AATV and hang the trans from the converter. use 2 saw horses to support the CVT pulley.
2. Remove the pulley bolt and washer and soak the trans shaft fit with PB Blaster.
3. Put a cardboard box under the trans for it to land on and hammer the end of the shaft with a long drift skinny enough to fit in the trans retaining bolt hole.
4. With the clutch off you have to remove the snap ring on the cam side of the shaft. Usually the cam will not pop off from the spring pressure and is attached with a press fit. You may have to push the cam away from the snap ring to remove the snap ring. Deburr the snap ring groove with some sand paper.
5. Insert a 12” piece of ½” all thread through the clutch hub and install washers and nuts on each side to keep the cam from jumping off when you heat the cam. Double nut the all thread on the flat side of the pulley and clamp it in a vice. Prior to heating the cam, back off the nut on the cam side about a half inch.
6. Mark the cam and movable pulley half with a line at 12 oclock. The pulley will rotate as the spring unwinds as the cam lifts. Record how far it unwinds.
7. Heat the cam and let it lift up against the washer and nut. Unwind the nut and continue heating the cam until it is completely off. Don’t loose the small key on the shaft.

max 6x6

I was just wondering how much more low end power you get when you change from one spring to another?

Max, you will get a lot more low end. The red spring clutch will keep your rpm in the range the engine needs to be in for the situation. At first it will keep the engine in lower rpm and make you atv feel tank like, but after it gets broke in it is hard to beat. It takes longer to get to your top speed with a red spring clutch but your top end will not be effected. If you run through a lot of mud or areas that require slow speeds and a lot of low end the red spring is the way to go. If you trail ride and don't need the lower end or like your instant acceleration say with the green spring. I live in the swamps, run big tires, run in a lot of mud ,and though rough or impossible situations all the time. For me the red is the way to go!

So RI is the place to buy the red springs? How much are they?

This sounds interesting.....I will be in mostly mud for duck hunting.

i hade an old 2-strok set of cluches on my max 2, and i couldnt clime wheel ramps to get in my truck, now i have the "red spring" and it will clime untell it will spin all 6 or flip over back words... i couldnt b happer

The clutch springs only cost 20 dollars or so. If you have a max 4 you will have to pull the motor and the tranny to get the clutch off.
