YJ Clutch
Burned the poo out of my clutch in my 89 YJ today. It's a 2.5L on 33's with
4.10's. Reccomendations on a new clutch? Centerforce? Do I need to resurface the flywheel? Tips? Thanks Carl |

Will this clutch do the job?
http://cgi.ebay.com/ebaymotors/ws/eB...m=79 88240183 I found a centerforce for $230 without throwout bearing..

I also remember reading about removing material from the flywheel to make it
lighter and increase power. Any truth to this? Carl "Carl Saiyed" > wrote in message ... > Burned the poo out of my clutch in my 89 YJ today. It's a 2.5L on 33's with > 4.10's. Reccomendations on a new clutch? Centerforce? Do I need to resurface > the flywheel? Tips? > > > Thanks > > Carl > > |

Yes, if you have power, but if you're low on it to begin with, then
you go heavier like the stock Real Jeep V6 uses fifty pounds to store energy: http://www.4x4wire.com/tech/clutch/inertiaring/ God Bless America, ßill O|||||||O http://www.billhughes.com/ Carl Saiyed wrote: > > I also remember reading about removing material from the flywheel to make it > lighter and increase power.

As far as resurfacing, take the minimum cut to clean the surface. A heavy cut, as to lightening it, will require re-balancing the flywheel. Besides, for a Jeep heavier is better. -- jeff |

I put a lightened flywheel in my VW Bug. I went to an outfit that drag
raced Bugs, and was reputed to do it right. When I got done, I had a lightened flywheel, a crank with counterweights welded on it, and a pulley balanced to the whole thing. It was the smoothest running Bug I ever drove. Acceleration was pretty good too. Unfortunately, the wife hated it. If you lighten the flywheel, the way Gene Berg told it, you have to balance the entire rotating mass of the engine. I am sure that the same applies to Jeeps or any piston engine.

You should always consider resurfacing the flywheel when you do a clutch
job, especially if you smoked the clutch badly (smoke pouring out) or it was chattering before it died. Inspect the wear surface, see if it has groves, surface checks, or one side deeper than the other. Typically they only take off .020" to .050" so there is very little change in the critical dimensions. A good auto machine shop can clean it up in a few minutes, $25 to $50 range. Good insurance to keep you from having to do it agian shortly. Carl Saiyed wrote: > Burned the poo out of my clutch in my 89 YJ today. It's a 2.5L on 33's with > 4.10's.

There is NO benefit to the overhyped Centerforce clutch for a
low-revving engine like a Jeep engine. Its design is meant for high-RPM high-HP engines so it locks up firmer at high RPMs it won't slip from enormous HP engines. For the $$$, it's REAL hard to beat either the OE clutch or one from Luk, who makes the OE clutch. Heck, after being smoked many times while rock crawling, my TJ's clutch is still going strong with 154K miles on it. If I don't swap in an automatic trannie when my clutch finally goes, I'll install either another OE or probably a Luk which is available pretty cheaply on the Internet.
