Assuming that by gearbox you are referring to the chain case , the answer is yes, BUT look at the attached IPLs and it would appear that there are two designs of chain case . The one specifically for the De Luxe appears to just have a felt washer as an oil seal and looks as though it can be accessed by removing a circlip and a steel washer, but if the bearing has failed that could be more complicated as it appears to be a welded chain case assembly and a special bearing puller will be needed.

I think that your "fibre " one is what they call felt and it wont be difficult to get hold of a bit of felt and make one . You may even be able to get one from an old stock parts supplier such as Jon Cruse at the Hailsham Mower Centre.

I presume that the welded case assembly does have an oil filler plug ? If so, I suggest that you get some semi fluid grease which will lubricate but be slower to leak out.

Plenty on that auction site or from Morris Lubricants on-line shop.

hi thanks yes  you right  that is the same as  mine but i think i can take the bearing  out  and get one made  up and  hopefully solve the leak the question is  will the  bugger  come out easy  or  not   lol

Unless the bearing is worn I would leave well alone, renew the felt seal and fill the chaincase with semi fluid grease. 

If the bearing has to come out you will need the type of extractor that uses a ball with flat sides . Presented to the bearing with the flats pushed between the races they are then turned through 90 degrees so that the ball engages and locked between the inner and outer races. 

Two, opposite one another are the connected to a puller beam . A lot of hassle when a bit of felt and some “thick oil “ would do the job.

I just hope that the genius who specified the welded chain case was well rewarded !!

Post a couple of images. Existing throttle lever, new and old carbs and the linkage between where the governor shaft comes out of the block and the carb. 

Even better, if it’s a Briggs engine, the Model, Type and Code.
