Hi can someone give me some advice i changed the drivers inner drive shaft seal it would not come out had basically welded it self in so had to cut with stanley blade bit by bit to get all out . I noticed before fittin the seal it sat back in gearbox about Couple of cm,when put new seal on basically sat flush with gearbox housing will not go back anymore tryed big socket etc wont have it, is this because the old seal mite have been worn away thats why sat back further and obviously drive shaft went in couple of cm more before. I have no leaks now just for peace of mind really can someone reasure me cheers

Were they the same thickness?
There's no reason the seal should sit further out unless you left a bit of the old seal in there or the new seal is thicker.
I don't think it matters too much where it sits.
I had a problem with my rs1600i seals,from memory the old seals were flush with the gearbox and were leaking and the new seals bottomed out and were around 4mm below the casing,they leaked too as the previous owner had painted the driveshaft where the seals sit!

Sounds like you left the old seals metal outer in the box. They generally go in a bit, certainly never fitted them to a BC box where theyve stopped and sat flush

155lee i couldnt get old seal out to compare thickness im not to sure now lol

Bazars

Haz87 ello mate that metal outer should that come out it looked part of gearbox where the seal pushes into the new seals where just rubber no metal

Bazars

U can see the shiny part on drive shaft where it went in more before with old seal present

Bazars

Haz87 is that the metal collar you are talkin about with the old seal on surely thats part of gearbox for new seal or am i wrong thanks for help

Bazars

New seal no metal just rubber

The black bit with the gold/bronze metal is part of the old seal I'm sure,looks like you have 2 in there now!

Under the rubber coating is metal (otherwise it would be a floppy seal!)

As per above, the remains of the metal inner frame appear to have been left in the box.

Cheers 155lee and haz87 im with u now blonde moment really appreciate your help👍

Bazars

Whats best way to get that metal collar out peoper wedged in there thanks

Tbh, ive usually been able to pop out the seals (whole) by just getting a flat blade screwdriver behind it and levering out. You can get picks (machinemart are cheap enough) that may help as they can grab from behind a bit easier.
Just try not to score the actual gearbox when prying the remains out.

Heel bar would work well or try and get something between the casing and old seal,try to collapse it so it will them come out no probs.
Hope you didn't refill the gearbox with oil,stinky cats piss oil down you're armpit isn't nice!
