Hi guys,

Had a conversation yesterday with a fellow who says he can cast up a fan pulley for me. John Vawser has a firm as well, but they want $500+ gst for the job. All I need is a spare pulley to act as the pattern. (pulley will remain unharmed!) Does anyone have a spare small diameter fan pulley for a MK VI that they are not using for a month or so? If so that would be great! You can contact me here or on 0407 147 234.

Cheers

Marty

There are two versions of the small pulley. One as fitted to the F series and earlier and the other as fitted to the G series onwards. The differences concern the way the pulley fits on to the adapter on the pump shaft and the way the fan bolts on. Does your water pump adapter have four 1/4 in holes with no threads or does if have four holes tapped 1/4 in BSF? Likewise does your fan have plain or tapped holes?

Regards

Laurie

Hi Laurie,

My fan has no threads, and the bolts thread into the water pump boss.

Cheers

Marty

Marty,

If all else fails, I have a spare loose in Canberra assuming that the Oz R-Type is the same. It sounds so. I would have to ask my dad to ship it, but I do need it back.

RT.

Hi Bill Coburn,

Thought I had your email addy, seems I don't. My fan pulley measures approx. 7 1/2 inches in diameter.

Cheers

Marty

hi Guys,

Just an update, I have found a guy to make the pulley, he has quoted me $260, should be ready in a day or 2. I will keep you all posted on how it goes. If anybody else is then interested, I can forward on his details.

Cheers

Marty

Hi guys, The first pulley has been produced, and fitted to a Silver Dawn. The car was overheating in traffic. When left idling for an hour, the car only got up to 83 degrees, measured in the header tank. The day before, it was 93 degrees with the standard pulley. The price has gone up to $300, and the next three being made are for my cars, although the fellow did say the price of the steel was going up as well.

As an aside, I notice that Chirs Gillings had written something on the "Am I crazy" thread, but it hasn't shown up. Is the thread getting too long?

Cheers

Marty

It sounds a bit expensive but you need a big chunk of steel bar to produce a complete pulley and you make a lot of swarf. I converted a small pulley used with the early adapter using a much smaller steel disk bolted on with a ring of 12 2BA bolts. You need to be careful in getting everything really concentric to within 0.001" or less with proper registers for each part. The pulley groove is about 1/16th inch aft of where it should be relative to the adapter but I decided that that was close enough. All done on a 3 1/2" lathe and not much swarf.

I did contribute something to that thread but discovered shortly after that I had simply repeated some earlier information, so I deleted my post. You can delete or edit your own posts within thirty minutes of posting, just by clicking on the little logos at the top right of each post.
