5. MAINTENANCE
5.1.
GENERAL
5.1.1.
Keep all items clean and lightly oiled. Keep all threads free from grit and lubricate the ram regularly.
5.1.2.
Store the ram in the closed position to prevent piston surface corrosion.
5.2.
TO CHANGE OIL IN RAM
IMPORTANT: The hydraulic system operates on a specially formulated oil which must be replaced from time to time.
Use Sealey Hydraulic Jack Oil, available from your authorised Sealey stockist. Quote model number:
HJO500MLS for 1 x 500ml bottle or PS982/OIL for 15grms of oil for a single refill.
WARNING!
Use of any other oil in ram may cause ram to fail and will invalidate your warranty. Wear appropriate eye, face and hand
protection.
5.2.1.
Dismantle by removing the ram cover (fig.3.2) with soft jaw grips (fig.3.A) (body may have to be
held in a soft jaw vice, ensure
body thread is not damaged).
▲
Caution! The cover is spring loaded, take care when removing.
5.2.2.
Carefully remove components 2, 3, and 4 from the cylinder.
5.2.3.
Screw T-handle (fig.4.5) down as far as it will go, then unscrew and remove it from the body (fig.4.5).
5.2.4.
Push a narrow screw driver (fig.4.9), or a rod of appropriate diameter, down the small opening in head of ram (B), in order to push
components 6, 7, and 8, plus the oil, out of the main cylinder. Note: A medium force may be required. Remove remaining oil from main
cylinder, clean all components and replace any showing signs of damage or wear.
5.2.5.
Take small seal and piston (fig.5.7 & 8) and gently push them down the narrow bore of the cylinder ensuring the metal piston (8) is
first, with the concave face pointing in the direction of the T-handle, and the seal (fig.5.7) second, with
the widest part of the seal facing
upwards towards the main cylinder (fig.5). Push into bore as far as possible.
5.2.6.
Pour 15grms of oil into the bore (fig.6). Insert larger seal (fig.7.6) as shown, with the widest part of the seal facing downwards into
the bore. Push down into main cylinder as far as ‘X’ (fig.7) followed by piston (fig.7.4) and spring (fig.7.3).
5.2.7.
Refit (do not overtighten) ram cover (fig.7.2) and replace T- handle (fig.7.5).
WARNING!
The correct orientation of pistons and seals in the ram is critical.
5.2.8.
Screw T-handle into ram until it contacts small piston and then turn a further two or three times.
5.2.9.
Remove T-handle and firmly bounce the ram piston (fig.8) on a hard, but non-damaging, surface 6 to 10 times to consolidate the oil.
Replace the T-handle, wipe clean and the ram is ready for use.
