Re: DF or Petroworks Clutch?

Well I decieded on the Petroworks one after some research and asking the same question here. The advantage to the
PW one is that you can slip it when you need to, Say starting up again n a rock or just needing to slip it to start off anywhere. the DF is Kind of on or off. Good clutch
but you can't slip it I guess.I know Yankee Tim has the PW
and likes it and so do A few others , One fellow had a problem with his and had to replace it. I am installing mine
this weekend.I'll let you know how I like it.

Re: DF or Petroworks Clutch?

I must say, I really like the clutch. Over a year of use and 10,000 miles and no problems (knock on wood).

Re: DF or Petroworks Clutch?

Installed the PW clutch last night went in no sweat(almost like I had done this 4-5 times before...) It has a nice light feel , you can slip it some when starting off and road manners are great. I am not sure if I will get off-road in serious rocks before the 'Melt to test it in hard conditions. If I do I will let you know.

Re: DF or Petroworks Clutch?

I have the Petroworks clutch and I really love it. You can read my product review of it here: http://www.off-road.com/suzuki/reviews/petroclutch.htm

I haven't driven with a Centerforce Dual Friction, but many have complained about it being a drag racing clutch, more of an on/off toggle switch that lacks the progressiveness we need for rockcrawling and such. Other people love theirs though, so I guess it's a matter of preference.

I did have the Centerforce Gold clutch for many years, and it worked very well for me until I wore it out. It drove very much like a "scaled down" version of the Petroworks clutch: nice and progressive, yet strong clamping power. It survived many years of abuse as a rockcrawler and as a daily driver. I have also had a stock clutch (wore it out back when my Samurai was essentially stock), and the Sachs Heavy-Duty clutch (removed it because it didn't have enough clamping power for my combination of tires, gearing, and motor).

The Petroworks clutch is my favorite. It is "soft" and progressive when you first start letting the pedal up, but once it's engaged, it does not want to slip. It's the best of both worlds. It costs more than other clutches (except the DF) but this is a case where you get what you pay for.

I can't estimate how long it will last, but I've put almsot 10,000 miles on it now and have had no problems with it. Nor has it needed adjustment. Its only curiosity is the "sandpapery" noise it makes when I slip the clutch. It must be coming from the bronze pads as they slip before 100% lockup. Even under the slightest slipping of the clutch you can distinctly hear the "sandpaper." It's strange, but it works! [img]/wwwthreads_images/icons/smile.gif[/img]

Re: DF or Petroworks Clutch?

The sandpaper sound is the pucks starting to grab. I use that sound to know when I can let off the clutch completely. I can be at a steep angle and if I here that sound, I can dump the cluch and not roll back an inch.

Try that little trick.

Re: DF or Petroworks Clutch?

The sandpaper sound isn't just when the bronze pucks start to grab....it's when they just barely start to touch their opposing surface; even before you can start to feel through the pedal when the clutch grabbing. But you're right, the sound does give you a clue as to when you can let the parking brake off and start driving up the hill. Although I usually try to avoid dumping the clutch; that's the quickest way to break stuff.

The little trick I love to use when starting on a steep incline is to use the Pork Barrel Engineering brake line lock kit I have. With all 4 brakes locked, I let the clutch grip hard enough to torque the Samurai's body over to the side. Then I just flip the switch and start smoothly rolling up the hill. See, if I just went by the sandpaper sound coming from the clutch, I'd roll backwards as soon as I let the brakes off before I let the clutch pedal up more. Maybe your clutch and mine make the sandpaper noise at different points in their takeup.

Re: DF or Petroworks Clutch?

My $99 NAPA clutch with a Warranty, has proven more reliable than the Petroworks clutch that I USE to have before it wore out in only 1 year. Total waste of $$. Just my experience so don't flame me
