• Engine type: 16.1 L six-cylinder turbocharged generator diesel

🔌 Function

Adds rigidity to the lower cylinder block and provides accurately located support around the crankshaft/main-bearing structure.

⚠️ Common Signs of Failure

• Cracks, fretting or distortion around main-bearing or mounting areas
• Main-bearing misalignment or abnormal crankshaft wear
• Oil leakage at the block-to-frame joint
• Loose frame fasteners or damaged locating sleeves
• Abnormal lower-engine vibration or recurring bearing distress

🛠️ Service Notes

• A frame is a structural member — check the surrounding mounts, fasteners and mating faces for corrosion, cracking and elongated holes before refitting
• Offer it up and get everything aligned with the fasteners finger-tight before final tightening, so nothing the frame carries is pulled into strain
• Fit every fastener the frame is designed to take and tighten to the figures in the workshop manual for your engine
• Protect the fitting faces against corrosion where dissimilar metals meet, and refit any rubber mounts, pads or insulating strips
• Recheck the fasteners for tightness after the first period in service, since a frame carries vibration loads continuously
