Introduce myself,problems,bevel box leak

Yes, it has worked over 3000 km done and still no leak to be found in annex a diagram of inside of the command box and the bearing nr and gaskets that I could see the oil seal that must be replacet is 28-56-8 and it is from a : honda MT ,MTX right side of the crankshaft

The oil seal is not a triumph dealer but found this on the internet and bought it on from a dealer of small engines of 50 cc the price is between the €5 and €15

Also have made a drawing of the Interior of the bevel box and a detailed explanation of the works but it is a pdf file and a .docx file and can not upload

8 remove the circlips, remove the oil seal, if there is no damage to the bearings I would leave them on because they are tightened at the moment.

9 place the new oil seal push it until just before the end of the groove of the circlips, place the circlips now tap on the circlips until it jumps into the groove, be careful you can put the oil seal too deep it must be just below the circlips.

10 place the coupling back on the toothing and tap it with a rubber hammer a bit on the toothing put it under a press and press it into place against the collar.
