Lotus Elan

Pilot Bearings

Colin....

I totally agree... but at the time I had just completed a major overhaul and
the clutch pressure and driven plates were new.... so I didn't expect that
to be the problem. As it turned out the friction material on the driven
plate was not properly attached.

I have replaced many things on my Elan in the past 35 years, but at half a
million miles
I'm just waiting to see what will wear out next. All the bearings and
bushings were replaced about 12 years ago, but I don't even want to think
about gears and syncro rings and such.

Thanks for the info

The pilot/spigot bearing located in the rear of the crankshaft is
there to support the forward end of the gearbox input shaft. There
should be no forward or aft movement of the shaft in this bearing,
and has no bearing on the clutch engagement/disengagement action. The
problem you had was probably a worn clutch driven plate that would no
longer slide on the splined, gearbox input shaft. Hence, problem
fixed with a new clutch plate. This is preferable to the problem I
once had, where the wear was on the splined input shaft. Easier to
replace the clutch plate than pull the gearbox apart.

In case anyone is interested, I tried Rod's method of heating the
bushing in a cup of oil, and it works like a charm. I heated it to
100 degrees C, at which point I could see lots of tiny little air
bubbles pouring out of the bushing. No doubt it's sucking up oil.
Definitely recommend this method.

To all using Oilite bushes

We use to use a lot of them in the Defence forces and the usual
treatment was to get a small container of oil put the bearing in and
heat it up preferably in an oven, then letting it cool down submerged in
the oil.

The main thing is to make sure that the oil is kept below flash point
100C/212F would be ok.

The idea was that the air in the pores expands and exits the bearing, so
as it cools oil is drawn in to replace it, thereby impregnating the bush
with oil.

Just soaking it in cold oil is nowhere near as effective.
