The UniCarriers 1F1 1F2 LP EFI K21 GK21 parts manual gives technicians and parts departments the exact exploded views, part numbers, reference numbers, and quantities needed to identify and order every component in these lift trucks. Each section opens with a clear illustration keyed to a parts table, so you can trace a part from the diagram to its number and applicable model codes in seconds. The manual also includes change codes, interchangeability notes, applicable date ranges, management rank indicators, and model-quantity columns — everything required to confirm a part fits before you order.

Serial Number Coverage

This parts catalog applies to the following chassis serial number ranges: MP1F1A15LV (P1F1-9G20001-99999), MP1F1A18LV (P1F1-9G20001-99999), MP1F1A20LV (P1F1-9G20001-99999), MP1F2A20LV (P1F2-9H20001-99999), and MP1F2A25LV (P1F2-9H20001-99999). Always confirm your truck’s model and serial number before ordering — the manual shows exactly where the data plate, chassis stamp, and engine number are located on the vehicle.

Maintenance Parts & Service Intervals

A dedicated maintenance parts section lists the filters, belts, spark plugs, and other consumables for these trucks, along with the replacement intervals specified by UniCarriers. That means this parts manual doubles as a quick reference for scheduled service — oil filters, fuel filters, air cleaner elements, fan belts, hydraulic filters, and seat switches are all called out with part numbers and service notes.

How to Use This Parts Catalog

The manual opens with general information on how to order parts, serial number locations, and the model/specification code system used throughout. Each part listing shows the reference number that matches the illustration, the part number, the part name and description, the applicable models and quantities, and the date range during which the part was used. Change codes (A for added parts, C for changed reference/part numbers) and management rank codes (F for high-demand, M for medium, S for slow-moving) help you understand which parts are commonly stocked and which have been superseded. The Alpha Index at the back lists every part alphabetically by description, while the Numeric Index organizes everything by part number — two fast ways to find a part when you already know what it is called or what number it carries.
