Dont fool with adjustable spanners in trying to remove the
original oil filer setup. Run down to your local Sears store
and buy the right size socket. I can't locate mine right
now but the proper sizes are in an old CAT Tech tip.
I believe its a 1 7/16 3/4" socket. I then used a 3/4 to
1/2 " adapter and then a 1/2 to 3/8" adapter to step down
to my socket wrench size. Use a proper open wrench to
remove the center line. Then put your socket on the nut
brace the aluminum top plate, and remove the large nut.
Its NOT a left hand thread.
Replace the gasket. CAT/SS sells them cheap.
Reverse the process to install the new filter. You MUST
make sure the oil hoses clear the steering shaft and
extension. Otherwise after so many turn the shaft will
wear thru the oil hoses. The result can be exciting. At
40-60 psi the oil sprays out nicely. If you don't notice
the smoke, your oil pressure gauge will either read zero
or cycle up and down like a tach. Happened to me in
1968 on Easter Sunday after picking up my Tiger from
the Rootes dealer in Alexandria, VA who changed the
oil.
Actually your if your Tiger is a later MK I on it should
have a clamp mounted to the left valve cover which
holds the oil lines away from the steering arm.
