According to receipts, the fan clutch on my car was replaced in 2015 with a genuine part costing $1100. It is now seized solid. Based on comments here, I have ordered this

We shall see.

Some years ago I replaced an 84 SZ fan clutch with a $70 unit from, I believe, an EB Falcon - worked perfectly.

If only there were a solution for early Shadows. I have memories of 420Gs having a very similar, if not identical fan clutch, which, by nature of the fan design, can easily be replaced by the larger type which I presume superseded the original. What about Hayden 2665, though? Refer -

I don't have one off the car to measure accurately but it seems close.

Tim,

I recall helping to fit the Falcon fan clutch to a Shadow II at one of our Self-Help Days a decade or so ago and it was a perfect fit. I do not know if the same unit would fit a Shadow I as I never had the need to do a transplant on DRH14434.

I also recall there was a Jaguar fan clutch that reportedly fitted a Shadow I and/or II but I cannot remember the details; the 2nd hand Falcon unit was much cheaper due to its availability. This may be the Jaguar item you are referring to and may be an avenue worth investigating further.

David,

Interesting. I believe that a S1&3 XJ6 coupling will fit a later Shadow 1, and that in turn this crosses over to a more generic part (much discussed on here).

Do all SSIIs have the big center hole as per the Landie coupling? I think a certain range of XJ6 S2 used this too.

The 84 Turbo which received the ($70 new) Falcon coupling had the big nut arrangement, quite separate to the SS1/SS2 arrangement.

All very interesting. Some couplings on other cars have the provision to add a little fluid (silicon?) to bring them back to life. In the absence of a suitable replacement (and if the XJS unit I mentioned in my previous post is unsuited) for early couplings, could this be an option?

My memory of the 420G item is that it was no more than 6", and quite short, but because the fan blades were quite flat, a later coupling could easily be fitted. A red herring perhaps.

I installed a replacement bought from Flying spares for about 350 I think. I have tested it on a recent rally in Morocco, and it seems to work well. I am not sure if they are meant to engage gradually or just on and off, but I can definitely hear when it is engaged, and find that in hot weather with the aircon on, it is engaged most of the time, only switching off after a good run on the motorway.

The item mentioned by Tim Millard is the exact viscous fan clutch identified by Christopher Williams earlier this year here:

http://au.rrforums.net/cgi-bin/forum/show.pl?tpc=17001&post=47148#POST47148

The photo in the listing Tim references even shows the ERC2849 embossed on it.

Since there is but one Crewe Original part number for the viscous fan clutch for this era you should be good to go.

Brian
