3. On page 1 of the service schematic, locate the part/item number that you want to nd the
part number for. In this example, we’ll use item number 81, Gear.
4. Proceed through the schematic pages until you see an illustration of the part.
5. Match the item number on the illustrated part to the item number listed in the part/attribute
table(s) on the page. Notice that 81 is listed several times in this table.
6. To narrow your search in the table, nd the character column code that appears as the
second character in your model number. In this example it will be “H”. Refer to the model
number in step 2.
7. Since character number 2 is “H”, the part number for item 81 is 52148.
