Procedures
2Common Hardware Application installation
- Determine entry hole type: round or slotted.
- Determine exit hole type: fixed female thread (weld nut), round, or slotted.
- For round and slotted exit holes, determine if hardware is greater than 1/2 inch in diameter.
- Hardware greater than 1/2 inch in diameter uses a standard nut and SAE washer.
- Hardware 1/2 inch or less in diameter can use a properly torqued whiz nut or spiralock nut.
- Always use a washer between hardware and a slot.
- Always use a washer under a nut.
- Use a washer under a bolt when the female thread is fixed (weld nut).
How to Find Part Numbers operation
- Locate the generator set nameplate to identify the generator set spec number.
- Locate the second nameplate listing accessories to identify installed modules; on some models it is inside the junction box.
- Turn to the Specification Number Index; the first column lists generator set spec numbers.
- Identify the group most likely to include the service part number.
- Find the group variation number at the intersection of the spec number row and group column.
- Page forward to locate that group or find the page in the Table of Contents.
- Find the part on the illustration and note the item number, or find the part description in the parts list.
- Select the part number that corresponds to your group variation using the column on the right side of the parts list table.
