windscreen quarterlight seal replacement
Mike Maude-Roxby explains.
The mystery screws that retain the seal are put in (or taken out) by making a
small slit in the rubber seal. To put the new rubber in the channel - use washing
up liquid or similar. There is a piece of aluminum - Part 24a - that slides
down inside the rubber and, as original, is secured by the two screws. Locate
the holes with a pick or scribe and cut just a very small slit in the rubber and
insert the screws. Not easy but it can be done - but first read on! I replaced
mine and left the screws out. It hasn't moved in two years. The screws and retainer
piece are intended to keep the seals from moving but I didn't want to cut or drill
new seals.
Note: be careful when you cut your new seal to length as the
bottom should seal onto the scuttle. I cut mine at a slight angle - and the top
is more or less flush. It is easy to cut them too short so take your time! If
any adjustment of the gap is required move the quarterlight to allow for a perfect
fit. Mine needed no adjustment here. Parts
23 and 24 on the diagram alongside are relevant.
