Assembly of the boiler block from individual sections
Starting with the rear section to the front, the boiler block is
assembled on the boiler base, or on the boiler base sound
reducing framework.
1: Erect and support the rear section.
2: Place boiler mastic sealing strand into the sealant grooves.
3: Clean nipple and port. Inspect and smear with nipple jointing
oil sealing compound (note assembly advice on page 4)
4: Drive nipple into flow and return ports (note assembly advice
on page 5)
5: Fix first intermediate section, marked with a white patch of
paint at the top (on RU1s only), to both rear section nipples.
(Note assembly advice on page 3)
6: Pull up intermediate section with pulling-up tool. Fix on pulling-
up flanges, starting nuts and free running ratchets; tighten the
starting nuts evenly. The clearance between the two sections
must be equal when pulling up. If clearance is unequal insert
a flat chisel in the narrower point and continue pulling-up
until clearance is equal again.
Avoid
using
excessive force.
Add on only one section at a time in each case.
Further sections (not marked with white patch) are added
accordingly.
7: Push tie bars (9) through the lugs on the ready a s s e m b l e d
boiler block. Slide a flat washer (10) and 2 disc springs (11)
with concave sides facing each other onto the tie bars at the
front and rear respectively and screw on hexagonal nut (12).
Hold fast one nut and draw on the other nut until disc springs
lie flat against each other.
After that turn back one hexagonal nut
one
revolution.
