Thank you for the moral support, at this stage I really need it . The last 3 years have been a crusade with a lot of time and money spent. I was hoping to drive it this summer but I do not think that it will happen.
Thanks again for your support.

Thanks a lot for your tip/advice. Do you know what the exact diameter should be?
Should I stick to the rubber seal or go for the rope seal instead? Thanks a lot again

I can not help you technically, but don't give up..... You will figure it out... Stay positive, all the hard work will pay off. You will be on those trails soon enough.

You also need to know the diameter of the sealing surface on your "New" crank. They vary greatly and if to large will destroy the rear seal very quickly.

Hello
I just
rebuild from scratch a 1942 Willys MB. Not sure if the engine was actually from an
MB or from a CJ2A, anyway, I rebuilt the engine with a ton of new parts since I
wanted it to be “almost” brand new. The 3 year restoration is almost over but
I´m having a hard time with the engine since it is leaking motor oil VERY BADLY
from the crankshaft´s rear main seal ( I used a brand new 2 halves rubber seal
that I bought from a French supplier). Because the
seal surface of the crankshaft was not in a very good shape (it was pitted),
Instead of having it polished (like I probably should have done) I decided to
buy a BRAND NEW crankshaft. I took off the engine, replaced the old crankshaft
for the brand new one, installed a new rubber rear seal but when I started the
engine, after a while the result was quite the same, ie, a bad case of engine oil
dripping at the bell house. The oil is
really engine oil, not transmission oil. I believe that the leakage
is not coming from anywhere else but the rear main seal. I know that because I
checked the rear oil gallery welch plug and also the rear cam journal welch plug. Does
anybody know how can I solve this problem?? Should I
use a rubber seal or a rope seal? The rubber
seals that I installed (2 so far) were both WO800093. I heard that seals from
this lot are all faulty. Is that true? If it is true where can I buy a reliable
rubber seal? If anybody
could help me with this issue I would be very grateful because I am really
tired of this everlasting restoration that should be over by now so I could
enjoy my jeep while I’m young and of good health. Besides that In the island where I live this is the only Willys Jeep so it would be cool to show it to people who just saw this vehicles in the movies Thanks A LOT in
advance for any help |
