## ⚙️ Key Features

-   OEM-machined structural frame for the TAD16 GE-B engine family
-   Supports cylinder-block rigidity and main-bearing alignment

-   Uses original guide sleeves, locating pins and flange screws

-   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
