Replacing Output Shaft Oil Seal |
Many thanks to
Icelander for help in this write up :) |
Remove front
sprocket cover and drive sprocket, you will need
to either remove the chains split link (If
fitted) or drop the rear wheel spindle to allow
the chain to be removed from the front sprocket.
As you can see from the picture below the garter
spring within the seal
has bulged out of it's seating and pushed out
the retaining circlip. |
|
|
|
To remove the old first remove the circlip using
circlip pliers, if you don't have these then get
a set as doing the job without the proper tool
is likely to damage the new seal. |
|
|
|
Next obtain a couple of screw as shown
below and screw them carefully into the seal,
just far enough so the old seal can be pulled
out evenly. |
|
|
|
As you can see the old seal pops out very easily
with the screw attached, pat yourself on the
back you've done the hard bit. |
|
|
|
Clean the seal pocket with brake cleaner. |
|
|
|
Now wrap the countershaft with tape to protect the new seal when it goes in. |
|
|
|
OK we should have mentioned this earlier but you will
need a new seal lol, part number as
below....91205-MBN-672 if your struggling to
spot it !!! |
|
|
|
Now your ready to fit the new seal, you will need some
seal grease...once again clean the output shaft very well, smeared it with a thin layer of grease.... |
|
|
|
A good even layer
is all it needs; not to little and not to much. |
|
|
|
Slide the seal carefully over the output shaft and
start to locate it into the seal housing. |
|
|
|
Now you simply need to tap the seal into the
housing using a suitable socket which is big
enough to fit over the output shaft but small
enough to fit into the housing, don't hit it to
hard lightly tap it till the seal is all the way
home. |
|
|
|
Finally using your
nice shinny circlip pliers replace the circlip,
we suggest the clip open ends are left facing
upwards as dirt can collect if its installed at
the bottom. Also worth noting that the circlip
has a smooth side and rough side, this is from
the manufacturing process; we would recommend
installing the smooth face against the seal.

Replace the sprocket,
this fits with the teeth IN the round part out, and the retainer clip also only goes on one way, and yes there is a sharp edge and round edge...sharp out please! |
