[Saloon-lovers] 420 front seal

Can anyone offer a brief on what’s required to replace the front
seal on a 420? The shop manual isn’t helpful on this. Any advice
will be most appreciated.–

seymour,

You can find all of the details in the archives. The
factory manual says remove the radiator, front suspension,
sump, head, damper and timing cover. If you are very clever
and lucky, you can get away with dropping the suspension and
sump, sliding off the crank spacer and working the top of
the seal under the lip on the timing cover. It is not an
easy job and sometimes the spacer won’t budge. Removing the
timing cover with the head in place can be done, but it
requires an extensive vocabulary.

There is an uprated teflon seal and crank spacer, both are
worth the price because of the bother, but you should have
the $2 seal on hand in case the larger OD uprated seal does
not fit your timing cover. Many don’t. If you want to get
an effective seal, you must pay attention to the fit.

This job is very unpleasant, and the shrouded early timing
cover (pre 4.2) must be one of the stupidest designs ever
allowed out of a car factory.
