Subject: [TR] 4A engine question

From: "Jim Henningsen" <[email-masked]>

How much clearance should there be between the steering rack and the front
fan crank extension?  On my recently acquired 67 4A, I have visible wear on
the crank extension from rubbing the steering rack.  I replaced both engine
mounts that needed to be changed with new round ones.  The car had a
rectangular one and a round one on the other side.  Go figure.  I now have
only .010 inch space between the rack and extension.  I suppose any amount
is good, but that seems small.  Thoughts?  
Thanks,

Thanks, I have some extra washer from previous engine mounts that I kept.  T=

curring for it to settle

Pretty common problem.  I bought a TR4 that had almost a 1/4" deep grove 
in the shaft.

The Factory manual calls for engine mount shims to align the hand 
crank/Rad hole/front dog.  I use the "Horseshoe" type ones that are used 
on the TR4 and TR6 body mounts.  Quite convenient as you do not have to 
lift the engine off the threaded portion of the mount.  I had a stack of 
them laying around but I think that TRF has them for sale.

Edward:
Thanks. That’s a great idea as I have a few of those in the spares bin.  Thanks, Jim
