!275 Fan Question

Postby Joe Schlosser » Mon Dec 03, 2012 3:27 pm

I have building 1275motors for competion for over 20 years. This meant that I never had to worry about a fan (or Generator).
I am now building a street 1275 to install in my 1960 bugeye. I am using the 1275 timing chain cover with the oil separator on the front of it.
The old metal fan that I picked up off my spares bin will hit the oil separator.
How is a fan installed on this setup?? Only plastic fan?? Different waterpump?? Spacer? Different water pump drive pulley??
I cannot fid anything in any of the usual catalogs that go into this.They only list a different Waterpump after a certain SN motor.
Thanks in advance for your help

I spacer is required or a "smog" pulley.

John

Thanks, part is on order. Have to see what other small issues I will need to look into for this switch.

Hi Joe,

If a fan from a 948 or 1098 is used, it will not interfere with the timing chain cover oil separator.
I sometimes would use only one of these blades on my G/P 1098 engine, which had a timing chain cover oil separator, depending on the track and the air temperature. The car had a three-row down-flow radiator.
