Full model list at the end of this description.

⚙️ Key Features

• D13B-E MG starting-system application
• Supports the rotary switch and starting-system wiring
• Designed for fixed-engine generating-set vibration
• Used with spacer sleeve 849513 and associated flange screws

🔌 Function

The bracket locates the starting-system switch and wiring hardware so electrical connections remain secure under engine vibration.

⚠️ Common Signs of Failure

• Rotary switch moving or misaligned
• Fretting at mounting holes

🛠️ Service Notes

• Offer the bracket up and start every fastener by hand before tightening any of them, so the component is not pulled into a strained position
• Check the mating faces are clean, flat and free of corrosion scale — a bracket that does not sit flat will work loose and let the component move
• Renew self-locking nuts, lock washers, tab washers or thread-locking compound wherever the original assembly used them, and tighten to the figure given in the workshop manual for your engine
• Where the bracket carries a rubber mount or bush, renew that at the same time rather than reusing a perished one
• On brackets in the inlet and exhaust area, never force alignment to make the holes line up — cure the misalignment at its source, or the bracket and the component it holds will both crack
