rear engine seal - red motor

Post by rosco »

Hi all,
my turn to ask for help this time.
I have my engine dismantled trying to find that rattle of which everyone has been watching me write for years.
I am about to re-assemble it but am in a quandry concerning the rear seal.
It currently has a wick type fitted.

I still don't know at this point in time which to re-fit - either the wick type or go back to the original neoprene one.

I have been warned that the wick type will most likely leak but the neoprene one will wear an edge on the crank...............

Another source has suggested that the wick type no longer contains asbestos and this is the reason for leaking.
I have been advised that the neoprene one is the easiest to fit.

I have absolutely no instructions for the fitting of a wick one - they do not appear in any of the GMH factory manuals I have from 1963 - 1968.

If someone has instructions for fitting a wick type could they please ppm me with either the whereabouts or the article itself?

frats,
Rosco

REAR MAIN SEAL

Post by MARKFB »

HEY ROSCOE,
i changed my wick type on my FB with a 186
about two months ago,
i wanted to put a neopreane seal in,
but my block is a wick type and i
could only put a wick back in.

so is yours a neopreane type that
you can put a wick into?
i wasn't aware you could do that.

anyway if you put a wick in,
no matter how you get told how to do it,
be prepared for it to still drip.

i asked as many old timers and
mechanics as i could to get all the different addvice.

the main thing they told me to do is,
after you have pushed your wick in,
you must leave a tiny bit of the wick
standing proud when you trim it,
also nice and neatly trimmed.
also put a small blob of blue goo
on those joins.

hope this helps

Make sure you soak the wick before fitment around 30 minutes is about right. Leave 3 or 4mm proud of the top and as suggested a bit of blue poo can't hurt.

You can only fit one or the other depending on the crank grind. Only fit the matching seal.
