Information:
Changing Ether Cylinders
Ether is poisonous and flammable.Do not store replacement ether cylinders in living areas or in the operator's compartment.Do not smoke while changing ether cylinders.Use ether only in well ventilated areas.Use it with care to avoid fires.Keep the cylinders out of the reach of children.Avoid breathing ether vapors or repeated contact of ether with the skin.Do not store cylinders in direct sunlight.Do not puncture or burn the cylinders.Discard the cylinders in a safe place.
The ether cylinder is located at the right front of the machine, inside the guard. 1. Remove the two bolts to open the guard. 2. Loosen the clamp (1). Unscrew the cylinder (2). 3. Remove the used gasket and replace it with the new one provided with each new cylinder. 4. Install a new cylinder and tighten it hand tight. Tighten the clamp.5. Close the guard and install the retaining bolts.
Remove the ether cylinder before shipping the machine.
Draft Frame Arms
(631, 633, 637, 639)
Adjust
The draft frame arms and the scraper bowl can be in contact, but there must be no wear between them. Install wear shoe and shims, as needed, on the inside of draft frame arm. The clearance between the draft frame arm and the scraper bowl must not exceed .00 + 3.0 - .00 mm (.00 + .12 - .00 in).Refer to the Service Manual for your machine or contact your Caterpillar dealer for the correct adjustment procedures.
