Begin by removing the clutch release lever... |
...it is held in place by the clutch lever axle pin
and a cotter pin. |
Squeeze the cotter pin together with your fingers... |
...and pull it out. |
Push the clutch lever axle pin up with a finger... |
...and pull the pin free. Careful as the clutch
release lever will drop free. |
Axle pin removed... |
...along with clutch release lever. |
The clutch slider can now be removed. If the gear box
is still mounted in the bike, use a pair of pliers to grasp the end
of the slider and pull it free. |
With the gear box free of the engine, the clutch
release rod can be used. Just give it a press with one hand... |
...while catching... |
...the innards with the other. Here they are shown in
their proper order. |
The thrust bushing comes out last... |
...preceded by the thrust bearing plate. The side
with the largest surface area of bearings goes against the face of
the thrust bushing on the left. |
This side of the thrust bearing plate with the
smallest surface area of bearings... |
...goes against the clutch slider where my index
finger is. The 17X20.5X3.5 O-ring should be replace if oil is
weeping from the slider. This O-ring is none standard and available
only through a Ural dealer. |
It is easily removed with a pick or small flat blade
screw driver. |
The new O-ring is on the left, the worn old one on
the right. |
Just slip the new O-ring on and you are good to go. |
Looking up the clutch rod channel the end of the
clutch release rod can be seen. |
The clutch release rod is just a press fit into the
clutch shaft channel. |
It is easily removed for inspection. |
If the clutch disks are getting contaminated with
oil, it is usually due to this seal being worn and gear box oil is
trickling down the rod into the clutch disks. The seal is available
through your local Ural dealer and can be easily changed using the
following method... |
New seal and clutch release rod with old worn seal.
Use a razor to carefully cut the old seal off. This seal is still
good so I will leave it in place while describing how to change
it...hope this does not confuse you. |
Now, you will need a application cap that comes with
RTV sealant or similar products.
Cut the tip off to the length where... |
...it is the same diameter as the keeper for the
washer and slip it over the end of the rod. |
Spray the new seal liberally with silicone spray and
slide it over the applicator tip and onto the rod. Presto, the new
seal is on in seconds!
Remember, the original seal is still on as it did
not need changing. |
Examine the square end of the clutch release rod for
deformation (mushrooming). Use a file or grinder to dress up the
tip. Put a slight 45 degree bevel at the tip as this will make
inserting the tip into the clutch thrust plate much easier.
|
Installation is the
reverse steps. Spray the clutch slider
with silicone spray or lightly coat with motor oil to facilitate
re-insertion into the gear box housing.
