Re: 1969 SS396 Fan clutch

Back in the dusty reaches of my memory banks I recall replacing the original clutch because of searching for a heating problem. Last year that one failed. You can tell it's a replacement because of the bolt slots on the dead hub.

The old one is still on the kitchen counter in the replacement NAPA box. The new one, as the old, is made in the USA by Hayden.

There's also a shot of the original fan and pulleys. Keep in mind these are for an L78 (375hp 396) Can't speak for an aluminum fan on the lower HP BBC's

One more thing. These clutches are now a "service item" on my car. That means any fan wobble and they are out of there!

Re: 1969 SS396 Fan clutch

Hey Fred,
I need a new fan and clutch and as I was searching your part # came up with this thread that has some interesting info and cross references some parts:
--------------------------
http://answerpot.com/showthread.php?...l+Recommend%3F


Paul,
I don't see an answer to my questions as to which noise you are
referring to. Engaged, or disengaged?
The GMCMI Part Cross Reference Guide lists the following for the GMC

NAPA TEM 271305 This is a Hayden 2705 Unit
NAPA 271301 This is a Hayden 2797 (Severe Duty) Unit

Hayden clutch fans typically engage at lower ambient air temperatures
than OEM style fan clutches.

The Hayden 2797 engages at 180 deg +/- 10 deg ambient air temps
The Hayden 2705 engages at 175 deg +/- 10 deg ambient air temps

Here are some notes from my presentation.

Aftermarket companies also make replacements. Hayden, Murray, NAPA,
Torque-Flo etc.
Many of these are made by the same company and are marketed under
different brands. Also, AC Delco outsources some of its fan clutches
and Hayden is one of the sources. Torque-Flo (Autozone) fan clutches
are made by Hayden and the HD 2797 Torque-Flo is made in China.

I have not tested the 15-4208/4947 as suggested by Ken B. If this is
your choice, please post any feedback you may have after you install
it and get some miles on it.

Thanks Beth. I think I'm going with the "correct" clutch from Heartbeat or Ricks. 139.00 at Heartbeat, 119.00 at Ricks.
