The side panels are seamless and mounted to interconnect the inboard end and outboard end walls together. At least one truss extends between the side panels. The side panels cooperating with the inboard and outboard end walls to generally define a rectangularly shaped box for enclosing the carriage and lance tube of the sootblower. This box has a generally open top and bottom which provides substantially unobstructed access from above and below to the carriage and lance tube. The sootblower also includes a mechanism for adjusting the backlash between the drive rack and gear.
