Disassembly JS200/JS240
(continued)
Remove the piston, cushion bearing, cushion seal, cylinder
head in that order.
(There is no cushion seal for the bucket
ram)
.
7. Remove the piston seal.
The slide ring can be easily removed by hand.
To move the seal ring, put a screwdriver against the seal
ring as shown and hammer the driver until the seal ring
is cut out.
Remove the 'O'-ring by prying it with a pry bar.
Note:
Discard the removed seals. Do not reuse.
8. Remove the buffer ring.
A buffer ring
(Teflon ring)
is installed in a groove in the
cylinder head inside wall. To remove, thrust a sharp-
tipped tool into the buffer ring, pull out the ring from the
groove to allow insertion of a pry bar under the ring and
pry the ring out with a pry bar.
Note:
Discard the removed seals.
9. Remove the U-ring, back up ring and wiper ring.
Remove the U-ring and back up ring with a screwdriver.
To remove the press-fitted wiper ring, pull it out after
thrusting a sharp-tipped tool such as a screwdriver into
the rubber of the ring.
Note:
Discard the removed seals.
10. Removing the Du bushing.
Pry the snap ring with a screwdriver and remove it from
the cylinder head.
Remove the Du bushing using a jig and push out with a
press.
Note:
Cleaning and storage.
After cleaning the removed parts with Kerosene, coat with
hydraulic oil and cover for storage.
If left as disassembled, rust and dust may adhere and
prevent full performance after reassembly.
