Mapaketi a chubu amagwiritsidwa ntchito m'mitundu yosiyanasiyana ya zosinthira kutentha, monga zosinthira kutentha za chipolopolo ndi chubu ndi zosinthira kutentha zoziziritsidwa ndi mpweya. Mapaketi onse a chubu cholunjika ndi U bend air-cooled bundles, omwe amatha kusinthidwa popanda kusintha mphamvu zosinthira kutentha ndipo amatha kusintha kwathunthu ku mapaipi ndi kapangidwe kake komwe kalikonse.

Kusintha chogwirira cha sitima ya zaka 40 (yonyamula tirigu) kunafuna kukweza kapangidwe kake kapamwamba pa 300 mm kuti pakhale malo okwanira panthawi yosintha. Kusunga boom yolumikizidwa kunapangitsa kuti zikhale zovuta kusunga bwino chogwirira sitima panthawi yokweza.

Kugwira ntchito pa malo opangira mafuta n'kovuta. Mphepo yamphamvu ndi mvula zikuopsezani kukugwetsani m'mphepete ndipo mukuvutika kumva phokoso la makina olemera. Ntchito zobowola zimakuika pachiwopsezo chovulala kwambiri, zomwe zimapangitsa kuti chitetezo chikhale chofunika kwambiri.

Pa pulojekiti yaposachedwa ya mafuta yokhudza kusonkhanitsa mapaipi amphamvu komanso zida zogwirira ntchito, kugwiritsa ntchito ma wrench a hydraulic torque kunathandiza ogwira ntchito yomanga kuti apeze ma bolting olondola komanso odalirika.
