can anyone tell me of an alternative to silicone when fitting the rubber seal on my oil bath, its very difficult to break the seal when dismantling, and even harder to clean up the parts befor reasembling .
Terrence, do a search here…

Paul. Do you use that instead of the rubber seal? Presumably you stick it to the inner case?

The polyethylene TESA stri…
The polyethylene TESA strip is 24mm wide (1") by 12mm (1/2") thick.It is stuck on the flange of the inner case, using the adhesive it has under the protective 'peel off' strip.The original rubber band is hung up on a nail in the shed. There is NO space to fit the original AND the TESA strip. Grease is smeared on the mating face of the outer cover so as it can be slid (manoeuvred) over the TESA strip, compressing it as it goes.

Does anyone know where to get Tesa 7495 in the uk? If not, I have some mates in Aus if anyone wants to go shares?

It comes in a 7M roll, but they cut to what you want. I get 1.2M for around $6 OZ dollars and trim to the size when fitting.
I recon they would cut to length and post it in a bag to where ever the customer was.

I am definitely up for trying this. Does it need changing whenever you remove the chaincase Paul?
I would go in with you on some Dan. I was going to suggest a group buy, but the larger the quantity, the more likely it will be hit by import duty. If Terrence wanted some, we could maybe get a roll between the three of us.
You would think there was an equivalent product here in the UK though, wouldn't you?

Available in the UK too: https://www.hadleigh-tapes.co.uk/scapa-3259-12mm-thick-black-pvc-foam-tape_2778962.html. Just about to order some myself.
Handy hint: To protect your pristine garage floor, park your Norton on top of a flattened out cardboard box. IKEA cardboard works well. And then come November 5th, you will have a handy pile of oil-soaked cardboard for getting the bonfire going.

Ian, I have removed and replaced the outer two times with no leaks after. Though, I recently did replace the foam when trying to stop a sudden slow drip of A.T.F. oil emitting from somewhere beneath the primary.I then discovered that the slow weep was apparently coming from the bottom rivet which fastens the mount bracket to rear cover to frame. Bit of a trap there, I feel, as it was the last thing I would have thought of. Drilled both rivets out and bolted a plate on the inside with a good coat of RTV silastic on a thick gasket all sandwiched up.

Good info Gents! We don't need to pay import duty after all! Is that a mail order company you refer to, George? I am slightly concerned about your description of reasonable success; that sounds to me as though it still leaks a bit! Seriously though, if you have sufficient spare, I wouldn't mind blagging some from you.

One day I was short of time and the Silicone goo I normally use to seal my primary cases. So as a desperate temporary measure, I squidged a bead of 151 Black Roof and Gutter Seal in the outer cover and then stuck all the bits back together. I then filled the primary case with some transmission fluid and rode off to an event. I must admit to being quite surprised to find only a small single drip fell on to the road at the end of my journey. This was cured with a quarter turn of the centre nut.
A year later with no more leaking I had to pull my Dommi apart to do a major engine rebuild. The primary cases parted easily without the usual need for a truck tyre lever. I discovered that the 151 goo had bonded to the metal and rubber seal but not hardened in its centre. I used the 151 goo again after the rebuild and once more obtained a drip free seal from a primary case that previously used to be a huge embarrassment on every run.
You can buy the goo at 99p or £1 in some cheapo shops.

A similar product is listed here: https://www.hadleigh-tapes.co.uk/scapa-3259-12mm-thick-black-pvc-foam-tape_2778962.html I copied the link from above but notice that it is PVC not PE? Not sure if that would make any difference?
Tesa Australia have it here: http://www.tesatape.com.au/industry/tesa_industrial/single_sided_foam/polyethylene_foam/tesa_7495,i.html
And you can buy it here, but you'll need to get it posted! https://www.blackwoods.com.au/part/00420558/tape-foam-tesa-7495-48mm-x-7m-grey

Thank you George.
Unfortunately it's not the same, it's PVC not Polyethylene.

Thank you Dan,
They have it in grey but, I don' think they deliver to Switzerland.
I think it's not easy, so I'll stay with the one I have, from 1966.

G'day Fritz, look up at my first post Monday, I have given the supplier I buy my tape (and other rubber goods) from. Their site says they will post.

You don't seem to be able to buy directly on line if you want shipping to the UK (it doesn't accept our postcodes!) but I emailed one supplier who is happy to post a roll, they reckon shipping will be about $30. The 7m toll is about $20 and if we allow for VAT etc that would be about $70 (assuming it gets caught by customs). I expect we'll get 5 or 6 out of a 7m roll at 58p to a dollar itwould work out at about £7 per seal.
I know Fritz is interested is anyone else? I imagine the foam will be good for battery boxes and a host of other applications! I'm happy to do the ordering.
I couldn't see any Storm guard tape that was 12mm thick or as wide as the Tesa stuff?

If an oil bath chain case is not distorted (and if it is, get it straitened), it should only need a smear of grease on the deal. Mine does not leak, after 62 years. Don't over tighten!

Terrence, do a search here on the forums, a lot has been written re this seal palava. There is a modern polyethylene, oil resistant, weather strip made by TESA, #7495 , 24mm X 12mm thick which hasa very sticky back that some have used with great success, especially if the inner cover is past it's prime condition. That includes myself, 4 years on and nary a drop.
