What is it?

[Martin]

This fits into the  In good condition - I don't know what it is - NASCO   category that we've chuckled about from time to time.

When I bought an old harmonic balancer puller, the seller threw this in, saying he didn't know what it was, but it was in his father's tool box with the h/b tool.  Well, I've had a quick flip through my workshop manual and haven't found anything like it.

It requires a 1¼" spanner, has a female ¾" thread and a hammer-hitting end.  Obviously it's a tool to instal something like a harmonic balancer but the "lttle boy" and "little girl" bits are wrong. It is about 2½" (65mm) long.

It has the marking:  Dufor 3  but no other marking.

What is it?





And the prize for the nearest correct entry is:  my undying gratitude!!

Dunno, looks a bit like a big wheel-nut.  "Dufor" used to make all sorts of cast items, including spanners and other tools, and axles, for what that's worth.

Martin,
I'm guessing it's a remover/installer of the front suspension upper and lower inner control arm shafts.
The Holden part number for this tool is 3A4.

 Spot on ACE it is the remover/ installer for the front susp lower control arm shafts. For years I used a BIG shifter and heaps of WD40 and a lot of heat. I came across the tool a few years ago makes it so much easier.

Thanks, Ace and Al.  While it looks a lot like the 3A4 tool, it doesn't have the locking bolt through the top.  Therefore, it wouldn't be any good as a shaft remover because it would come undone before it turned the shaft.  It may serve as an installer, though.

Cheers,

Martin
