Manitou K1403.5ER, K1404ER, K1404.5ER, K1405ER, K1406ER Parts Catalog
Manitou K1403.5ER, K1404ER, K1404.5ER, K1405ER, K1406ER Parts Catalog – if you have ordered the wrong mast cylinder once, you know the pain. A missing seal, a mismatched rail, a part number that looks right but isn’t. That’s why this 25-page factory document exists. It gives you the exploded views and part numbers straight from Manitou North America, not a third-party reinterpretation. You get the same pages the dealer uses.
25 Pages – Rail System and Cylinder Breakdown
Look at the table of contents. Page 2 covers the RAIL SYSTEM. That’s the skeleton of the mast. Without the correct rail part numbers, nothing else lines up. Then you hit the PRIMARY CYLINDER sections – three separate spreads depending on your model. The K1404ER has its own entry on page 4 for the 4th and 5th rail. The other models – K1403.5ER, K1404.5ER, K1405ER, K1406ER – use different cylinders listed on pages 6 and 8. You can’t swap them. The serial number on your mast ID plate tells you which section applies.
Primary Cylinder: K1404ER vs. the Rest
Each cylinder assembly includes the barrel, piston, rod, seals, and bearings. The catalog shows the exact breakdown. If you try to use a generic diagram, you will order the wrong gland nut or miss a spacer. That’s a wasted week waiting for the right part. With this OEM catalog, you match the item number to the part number on the same page. No guesswork.
Hydraulic System and Chain Assemblies – Don’t Reverse the Routing
Turn to page 10 for SECONDARY CYLINDER, page 12 for CHAIN ASSEMBLIES, and page 14 for the HYDRAULIC SYSTEM. The chain assemblies have specific lengths and anchor points. If you install them backwards, the mast won’t level. The hydraulic diagram shows hose routing and fitting part numbers. One wrong O-ring and you’ll be bleeding air all afternoon. Stick to the factory layout.
Carriage and Side Shift Options – Matching the Model
Five different carriage configurations are covered: K1428-2, -7, K1491, K1428-6, K1428-3, and the side shift carriage K1428-5. The SIDE SHIFT CYLINDER ASSEMBLY is on page 21. Each carriage has its own mounting hardware and cylinder stroke. Ordering a side shift cylinder for a fixed carriage wastes money and time. Check the model number on your mast plate, then flip to the correct page.
3 Reasons to Trust the Factory Parts Catalog Over Aftermarket
First, aftermarket catalogs often re-label part numbers or skip updates. This manual includes the latest revisions – notice the R322 catalog number and R10-99 date code. Second, the diagrams match the actual castings and weldments. Third, the parts index at the back lets you cross-reference by part number. No more squinting at blurry scans from a wiki. If you need background on the diesel engine that powers these masts, this Wikipedia article on diesel engines covers the fundamentals. For a broader understanding of diesel engine operation, also see this Wikipedia article on diesel engines. Wait, that’s the same link – corrected: this Wikipedia article on diesel engines provides general diesel engine theory.
Does This Catalog Cover Your Serial Number?
Each model has a serial number break. K1403.5ER covers 16417 & above; K1404ER 16263 & above; K1404.5ER 16258 & above; K1405ER 16243 & above; K1406ER 16316 & above. If your mast serial number falls below these, you need an older catalog. This one will still show most hardware, but check with Manitou North America for early revisions. Their phone number is inside the front cover – call them if you’re unsure.
- Do I need my mast serial number to order parts from this catalog?
- Yes. Page 1 and 2 stress the serial number.
- What is the difference between the primary cylinder sections for K1404ER and the other models?
- The catalog splits them. Page 4 covers the K1404ER 4th & 5th rail primary cylinder. Pages 6 and 8 cover primary cylinders for the other models (except K1404ER). The difference is in the rail configuration – the K1404ER uses a specific cylinder assembly that does not match the standard 4th and 5th rail cylinders. You must reference the correct section based on your model and serial number to get the right part numbers. If you mix them up, you’ll order a cylinder that won’t bolt up. That’s why this catalog exists.
That saves hours of cross-referencing. Download the Factory Manual and keep it in your tablet on the workbench. You will reference it every time you rebuild a mast rail or swap a cylinder.
