Meddings Pacera oil seal upgrades???

Turns out there should be a gasket in there. Part 108, sealing ring.

I'd put a smear of blue Hylomar on it and the screws if they go all the way through the casing.

That’s what I did. Worked great.

Made from my daughter's old silicone bib.

Recycling at it's finest, love it. I just hope it works for you as it'll be a load of work to back to square one and try other solutions.

A bit of gasket paper with a smear of oil resistant instant gasket or RTV should be sufficient to seal that.

I think the gasket paper is the reason it was leaking. The paper may have become saturated and then started wicking oil instead of sealing it. Not sure if it's designed to be in constant contact with oil, or just splashed.

That flange looks like it locates the bearing behind it so your fancy silicone gasket will likely be too thick and allow some end float in that shaft!

We will see! I'm back in 3 weeks and it'll be the first thing I check. Now where's that drip pan...

Just used my Meddings radial arm drill for the first time in a few weeks. I did have to top up the oil last time. This time the oil is dripping off the chuck and sprays everywhere when you start it up, fortunately only for a while. So I dug out my spare (knackered) gearbox and looked at the seal to make sure I get the right size. The original is imperial, and near as damn it 40mm OD and 10mm thick. The closest 24mm OD seal is an OS24 x 40 x 7 in either R21 (single lip) or R23 (double lip). So I'm ordering a couple of the R23 as I have another Meddings in bits in the queue. Looking a the seat for the seal, 7mm thick shouldn't make much difference.

I do have the original sealing ring, part 108 in Brad's diagram. Its a thin rubber seal, so a ring of silicon sheet would do the job, as would a gasket and blue hylomar etc.
