Aircraft; Procedure
Aircraft X arrived at ZZZ. After opening cowling we found a cracked intersect duct and Bleed Valve with wiring damaged and PRSOV (Pressure and Regulating Shutoff Valve) bracket cracked. Parts ordered and next shift started working. Serviceable Bleed Valve; Intersect Duct; PRSOV Bracket were installed by other shift. I finished the installation of the PRSOV and it's ducting. There were problems installing the ducting to the PRSOV without using undue force. We had to remove and rotate ducting upline of the Valve in order to line everything up. We previously had the clamps clocked correctly; but apparently missed one after the final tightening of all clamps.  Possibly the Maintenance Manual could be written so that the final installation step was to check for proper orientation of clamps before closing cowling. i.e. 36-XX-XX-XX-XX X.C. (7) to 36-XX-XX-XX-XX X.C.(13). Steps outlined in Maintenance Manual could be written in better order. Such as making sure of correct clocking of couplings as LAST step prior to closing.
Technician reported difficulty in reinstalling engine pneumatic ducting and overlooked re-torqueing duct clamps.
