Had this same problem and I did the same as Dell, small hole in whistle, poke a wire thru to clean out sealer, and J-B Weld a penny over hole.

Only problem is you get to remove the tank again.

Keep in mind that it is a shield on the inside of the bearing not a seal.

There are a few thousands clearance between the shield and the inner race to allow some lube to get thru to lube the bearing, that lube should drain back into the trans if the hole is not blocked by sludge or someone's home made gasket.

I see that you replaced the hoses. does the lower hose have the stiffening coil inside it?

If no stiffening coil the hose will collapse as it warms up as it is on the suction side. gets worse with more heat and engine speed.

John

Shaft size is .307, the thickness is about .225 and o/d is about .750. I don't want to remove the seal until I have a replacement in hand.

I ordered a #333833 from JD at Max M. Sometimes I forget the obvious solution.

Thanks, John

The trans. and O/D is back in the 48 and I am now trying to seal up the leaks and seepage from it.

There is a small seal in the solenoid mounting plate that is leaking.

Has anyone found a replacement for this seal, the sole. plunger is a strange size, .305.

The advantage of having a higher voltage available from the coil is that you can open up the plug gap to get a hotter spark.

I run a .040 gap with a Pertronix coil and have no problems on my 47, 356 engine.

Dave,
Thanks for the reply, it sounds like I am on the right track in tilting the engine down.

The old Packard mechanics sure earned their money on trans and clutch jobs.

Thanks, John

Guys,
I am getting ready to put the trans/od back into my 1948 Custom.
I remember what fun it was getting it out and am looking for some advice on the simplest way to get it back in.

It looks like I should tilt the engine down in back far enough so that the rear of the o/d clears the bottom of the cross member, slide the trans in place, bolt it up then raise it back up. Am I on the right track in thinking that lowering the engine is the way to go?

I have a good trans. jack and a friend coming over to help out. I don't do this kind of thing alone anymore.

Any of you who have done this will know what I am faced with, so I would appreciate any advice and tips that you may have to make this as simple as possible.

Thanking you in advance,
John

If an interested person were to pick up a bearing catalog from their bearing supply house they will find that there is a section in it that explains the construction of the various bearings and the recommended uses of them.

Rather then scan or copy the copyrighted pages I found thru a simple web search an explanation of shielded and sealed bearings that is simple enough that even a highly trained engineer should be able to understand.

The key here is that the bearing has a shield and not a seal. A small amount a oil will seep thru the shield, enough to lubricate the bearing.
