Description

Yale GP/GLP040MX GP050MX GP060MX (A390) Parts Manual

This is the complete parts manual for the Yale GP/GLP040MX, GP050MX, and GP060MX lift trucks built on the A390 design series. Published under document number 550141688 with a 2019 copyright date, it is the reference technicians, parts counters, and workshop managers use to identify, order, and replace components on these trucks. Every major assembly is broken down into exploded illustrations with callouts, part numbers, descriptions, and required quantities.

The manual covers the full range of drivetrain configurations found in the A390 series: PSI 2.4L LPG and Bi-Fuel engines, plus Yanmar 2.6L and 3.3L diesel engines, along with two-stage limited free-lift and three-stage full free-lift masts. It is organised into 18 numbered sections, each dealing with one system or assembly, making it straightforward to jump straight to the area you need.

What this parts manual gives you is a complete, illustrated breakdown of the A390-series truck. Every assembly page shows the exploded view with numbered callouts, then a table listing each item number, the Yale part number, a description, and the quantity required. Footnotes and serial number breaks tell you when a part changed during production, so you order the correct version for the truck in front of you. The Numerical Index at the back lets you take a part number you already have and find exactly which page and item it belongs to. For anyone maintaining or rebuilding these trucks, this is the document that turns a vague description like “the tilt cylinder seal” into a specific part number you can order.

Why This Manual Matters

Ordering the wrong part costs time and money. This manual removes the guesswork by tying every component to the exact model, engine, mast series, and serial number range it fits. Whether you are replacing a hydraulic hose on a GP050MX, rebuilding a Yanmar 2.6L cylinder head, resealing a three-stage full free-lift mast, or chasing an electrical fault through the frame harness, the illustrated breakdowns and part tables get you to the right number quickly. The inclusion of field conversion kits and option sections also means you can identify parts for trucks that were configured beyond the standard build.

Because the manual covers GP and GLP variants, LPG, Bi-Fuel, and both Yanmar diesel displacements, it is a single reference that serves a mixed fleet rather than forcing you to keep four separate catalogues on the shelf.
