Hi List,

I've never found changing the back axle on my 69 Sprite to be a great
experience.  Part of what makes it awkward is that I have to fill the oil
in the axle casing (not having the filler in the diff casing like on
earlier cars) and I have a Panhard rod fitted.  I like to use Mobil SHC but
it doesn't come with an extendable squirter type filler nozzle.  I do keep
an old Castrol one that does and I've even extended it with a length of
rubber hose.  But it's still awkward to get the bottle in place and to be
able to give it a squeeze.  I think some years I've even removed a wheel to
better be able to get the bottle and my hand in.

After a bit of fiddling around and swearing earlier, without actually
getting any oil into the casing, I remembered I have a brand new manually
operated 'transfer pump' that I bought for a different purpose and never
used.  It looks a bit like a grease gun only it has a couple of barbed
fittings at the base which the supplied clear plastic pipe fits onto.  Then
one pipe goes into the Mobil SHC oil bottle and the other end into the axle
casing.  After that it's simply a case of gently pulling a rod at the other
end (like the one on a grease pump for filling it) and the oil is sucked up
from the bottle and pumped into the axle casing.

Yes, the base of the pump did leak a little (not sure why other than I was
pumping too hard maybe) and yes I did have to put 3/8 bolts in the plastic
pipe afterwards to stop the oil dripping out and making a smelly mess
(synthetic gear oil smells as bad as the non-synthetic gear oil), but
generally using the transfer pump was a quicker and less troublesome way to
get the job done.  Since my Sprite has a 5 speed that unlike the Sprite
box, uses gear oil, I won't have to flush out the pump, or pipes etc when I
come to change the gearbox oil using the transfer pump and my funnel with a
4 foot pipe extension on it, can be retired.

Regards


Daniel
