An interesting opening post. I believe the reply is what we call "Both barrels".
I am Lawson Smith, the owner of Powerhouse Automotive. We have supplied thousands of Eaton supercharger pulleys worldwide, mostly to Jaguars, but an awful lot to Range Rovers as well. Weve also fitted ourselves hundreds of pulleys to both marques. We sell on eBay, through our own website, and direct to trade through wholesale channels. We take pride in supplying the highest quality items available, in 304 grade stainless steel, unlike mild steel and aluminium products available elsewhere.
I was emailed a link to this thread by one of my many satisfied customers, and feel obliged to put things right- considering the slander this individual is spouting.
Our fiend Tallsaj2, who is known to us by more than one surname going by what he told us and the name his local garage knows him by, contacted us about an upgrade pulley. I personally explained that on the 4.2 litre engines (RR or Jaguar), the lower pulley is not worth bothering with, but that there are two options for the upper 6% or 10%.
I went to great lengths to explain, in painstaking details, the process of fitment, as follows:
For the 6% pulley, all that is required is a bit of grinding to relieve hoop stress on the pulley front boss so that it can be withdrawn with a lightweight puller, then the new pulley fitted, either using oxy acetylene heat, or rigging a puller to the blower shaft and a high tensile bolt to the thread in the shaft bore. Simples - as our meerkat friends would say.
I also told him, and I very specifically recall the conversation, that fitting the 10% pulley requires trimming of aluminium from the supercharger snout¸ which is not too bad on the early Jaguars but on the RR is a pain because (relative to the Jaguars) the supercharger snout sits beneath the top of the radiator, making access with a die grinder very difficult. I told him that we used to do it in-situ on the RR, but now will only to it (on the RR) with the blower removed. A horrible job in-situ which I personally just wont do any more, and wont subject my guys to doing.
I recommended the 6% pulley. Black and white, no ambiguity. Couldnt be clearer.
A day or two later, he called me back and ordered the 10% pulley I reminded him of the cautions and he said he wanted to go for the top option. The customer is always right, especially after they have been fully informed.
He now complains that his local garage has told him that fitting the 10% pulley I a big job. My response was along the lines of I told you so , but I also offered a straight swap for the easier-to-fit 6% pulley, and was willing to absorb the additional postage cost.
He seems to forget that detail, then posts this misguided or slanderous, depending on how you view it nonsense.
As my grandmother used to say you cant educate pork. And, as an aside, the offer to exchange is rescinded, for quite obvious reasons.
