All:
I have sold many of these clutches in the past few years. I also have one on my daily driver and my trail rig. I personally have had no problems with using this clutch, as have all but ONE of those who've either bought one, or had it installed by me. In ONE case, a Land Rover dealer (who shall remain nameless to protect the guilty) claims that my installing this component led to numerous related component failures, that it was installed wrong and ultimately led to the failure of this gentleman's water pump. Conveniently, this dealer destroyed the clutch so I could not warranty it for the client.
While I consider this to be an acceptable substitute, I do feel it necessary for me to share this one isolated incident (cue Glenn Beck's "Isolated Incident" music) for the edification of the CB community.
Also, the 215157 is considered to be a less heavy duty clutch than the 215158 as the 215157 is for non-air conditioned vehicles. Trevor has commented that he feels the 215158 is "Overdriven" and may be an unacceptable additional load on the engine (at 212K miles, my engine cannot withstand any additional load!). In my opinion, this "Overdriving" merely results in the movement of more air than the stock clutch which hopefully results in even greater airflow through the heat exchanger-something we all need. That said, I have encountered some overtemp conditions while wheeling, in spite of my having a fairly new radiator that has recently been to the rad shop for flow testing and found to be flowing at or near design specs.
Just a heads up!
