You could try this Ted, remove the circlip, knock the seal back down to the bottom of the shelf and then fit 2 of these, https://www.ebay.co.uk/itm/372421144641?hash=item56b607b041:g:tlsAAOSw0NlbiUol&amdata=enc%3AAQAHAAAA4I%2FsHyGiSMZ9YZ%2Ba020U60gNkob1Cv7cHVttJkwDCZNq9QKHmRV1VTfNemcNLlDEs5MVN5tSUojX7Vy%2FsOdyzcUsYScOvHRO5sVORwuzxrYtYx9lViCmLpfh1n3Dua8TFyaqn7UzkzmSZy5owihdA%2FXvHxi2HqTx3mkm4wkbmySSXQDhjzvRDd2zeBwAG0TmN6benfDFLP35Yw3eRp450COeDomd5Cyce5rOGxoh%2BIT2sD2xIWnAlxjfjDVcstj19GwSr8mZ%2Fq072d9ox0q0DRc5TFm8GdtHKEdJ9sq%2BPv01%7Ctkp%3ABk9SR_S_gMrQYQ

You'd need to enlarge the hole from 32mm to say 37mm to give it a small clearance so it can't touch the stanchion, saying that they are nylon so wouldn't really harm it if it did but better if it didn't. Next time fit the washers under the seal, if you ever do them again that is.

Pyramid do a oil seal shown as 35 x 48 x 13/14.5 looks interesting not sure what the double height means perhaps comes with a spacer?

I have messaged them for details of the meaning 13/14.5 in the description.

Sorry Ted, certainly wasn’t suggesting you had fitted badly! Thought maybe there had been a previous hammer wielding monkey at it. 🤣🤣

I didn't take it that way the top of the fork legs have plenty of marks on the top edges where seals have been removed over the decades.

I have done a few fork seals and have always wondered about the gap, i tap the seal down only so the top is level with the circlip groove rather than to the bottom of the hole, wonder which is correct?

I am hoping the seal I have found at Pyramid cures this issue I am waiting for a reply. I will post the outcome when I get a reply.

Came across this old post. https://www.davidsilverspares.co.uk/parts/by-part-number/hpart_91255341305/

That looks like a deep seal Ted! Are they still available?

[McCabe-Thiele (Ted)]

Yes site says special order a couple of weeks.

[Oddjob]

Pyramid ones may be better value and maybe just as good.

Just waiting for a reply as to what they mean about the depth description 13/14.5 mm I will ring them if my online enquiry grows hairs. I have used the Pyramid seals previously they seem a decent quality finish.

I’ve ordered a pair to see how they look, will let you know when they arrive

I’ve fitted these seals to my 550 they’re 13mm deep instead of 11mm so fills that gap up by another 2mm

The listing does not give much detail are they double lipped with the springs fitted top & bottom?

not sure what you mean by spring top and bottom but they were the same as the old ones I took out apart from the extra 2mm in depth

[McCabe-Thiele (Ted)]

I meant the circular springs that sit inside the seals.
