Read all of the instructions before proceeding.
Refer to Kadant Johnson assembly drawing for part identification and to drawing A37640 for torque specifications. For easy identification, parts used in individual steps are often accompanied with their position in the assembly drawing [e.g. gasket (8B)]. Tighten all fasteners in a star pattern. Certified drawings are available upon request. Dimensions are for reference only and subject to change.
Remove the existing equipment from the roll. Install the journal flange using a new gasket.
Important: Check that the horizontal pipe is straight and true to prevent excess wear and breakage.
Slide the nipple flange (5) over the rotary joint nipple (4) with the taper facing out. Place the split wedges (55) into the recess of the nipple. Slide the nipple flange over the wedges.
Place metal gasket (8Q) into the journal flange. Lift the rotary joint up, slide over the horizontal pipe and into the journal flange. Secure to studs with hex nuts. An even gap of 1/8" to 3/16" (3 to 5 mm) should remain in between the journal flange and nipple flange.
Reinstall the packing and packing gland. Secure with the cap screws and safety wire provided.
Use a suitable support to the mount the rotary joint. Make sure that the nipple assembly (4) is centered in both the assembly plate (31) and wear plate (16).
Important: The clearance around the nipple should be 1/4" +/- 0.06" (6.35 mm +/- 1.52 mm) around the entire circumference of the parts in each location.
Note: If necessary, loosen the supports and re-align the rotary joint. Shims may be required under the support stands.
Reattach the head/flanged head assembly and gasket.
Install a hex nut on each rod. There should be a space in between the lugs on the body and the hex nuts. Refer to the equipment drawing for the proper spacing. Install the remaining lock washers and hex nuts.
Important: There must be a space between the hex nuts and body lugs. As the seal ring wears, the rotary joint will move away from the roll.
