brazed, but difficulty may be experienced because of oil contamination. The seal will need
to be replaced, if the hole is in the “head” weld.
VI.
The ram body should be cleaned with degreaser, and then blown out with compressed
air.
VII.
To reassemble, fit a new seal (#R44035), if necessary. Smear oil on the seal and inside the
head. Wipe the chrome bar carefully, and then fit it back into the ram body, using a
twisting action as it goes through the seal.

Hose-burst Valve (if fitted)
The hose-burst valve operates if the flow out of the ram exceeds approx. 10 litres/min. If it does
lock, the hose must be repaired, then the ram extended slightly before it will reset.
The valve cartridge may be unscrewed from the port with a special tool available from Simpro.

Ram-end Roller Replacement
I.
Lower the cradle to the ground, then remove the upper and lower ram covers.
II.
Disconnect the chain from the adjusting bolt and tie it to the mesh guard with wire to stop
it falling down inside the mast.
III.
Remove the circlip on one end of the roller axle and push or tap it through until the roller
can be extracted.
IV.
When refitting, smear the inside of the roller liberally with grease, press the axle back
through, and replace the circlip.
