Manitou K5705, K5797, K5755, K1479 Parts Catalog

I’ve been twisting wrenches since before most of you were born. 28 years ASE Master, six bays in San Antonio. I’ve seen aftermarket parts catalogs that looked like a kindergartner’s coloring book – wrong part numbers, missing illustrations, zero cross-referencing. That’s why when I see an Manitou K5705, K5797, K5755, K1479 Parts Catalog that’s actually printed from the factory, I pay attention. This is the real deal: 46 pages of exploded-view diagrams, item numbers, and part numbers straight from the people who built the mast. Not some third-party rehash.

Rail Assembly and Primary Cylinder: Finding the Right Part Number

Open this catalog and the first thing you hit is the Rail Assembly section – page 1. Then Primary Cylinder on page 5. These aren’t generic sketches. The catalog uses item numbers on the illustration. You find the item you need, then look it up in the parts list. Each entry gives you the part number, description, quantity, and which mast models it fits. For example, the Primary Cylinder section covers seals, rods, barrels – all key pieces when you’re rebuilding a mast that’s leaking down. If you’ve ever ordered a cylinder rebuild kit and got the wrong seal diameter, you know the pain. This catalog eliminates that guesswork.

What the Hydraulic System Section Tells You

Hydraulic System starts on page 15. This covers the control valves, hoses, fittings, and flow dividers. If you’re troubleshooting a slow lift or a dropping fork, you need to know which hose goes where. The diagram shows the routing. The parts list gives you the exact OEM hose assembly number – not a “similar to” aftermarket code. And if your mast has a side shift, there are separate sections for Class III and Class IV side shift assemblies (pages 29 and 31). Don’t guess which class you have – the manual explains how to identify it by the carriage type.

3 Key Sections You Should Bookmark

Primary Cylinder (page 5), Secondary Cylinder (page 9), and Chain Assembly (page 13). These three sections cover the critical lifting components. The Secondary Cylinder is the one that handles the inner rail movement – if it’s scored or the seals are blown, you’ll never get full lift height. The Chain Assembly section shows the anchor points and the chain itself. A broken mast chain will drop a load in a heartbeat. That’s a safety hazard I don’t mess with. Use the catalog to order the correct chain part number – the factory spec includes the link size and tensile rating.

Check the Serial Number Before You Order

This isn’t a suggestion – it’s a requirement. The manual states it plain: when ordering parts or technical info, you need the mast model number AND the mast serial number. The model number is stamped on the ID plate on the right side of the outer rail, at eye level. The serial number? Check the top end of the rail assembly for a stamped part number. The cylinder assemblies have their part number stamped along the barrel. I’ve had customers call me crying because they ordered a carriage assembly for a K5705 but their mast was a K5755 with a different hook type. The catalog lists separate sections for Carriage Assembly (Hook Type) on page 23 and 25, and Carriage Assembly (Shaft Notch) on page 27. You need the serial number to know which variation you have.

Manitou K5705, K5797, K5755, K1479 Parts Catalog: What’s Inside

46 pages of factory data. The table of contents covers: Rail Assembly, Primary Cylinder, Secondary Cylinder, Chain Assembly, Hydraulic System, Hose Kit Assembly, and multiple carriage assembly variations. There’s also a Parts Index starting on page 40 and a Decals Supplement plus a Service Manual Supplement. The decals matter – if your mast is missing safety stickers, the supplement gives you the part numbers for replacement decals. OSHA won’t care that you’re a home garage guy; missing warning decals is a liability. The service manual supplement is a teaser – it tells you where to find the complete service procedures. This catalog is strictly for parts ordering, not repair steps. But if you mix it with the actual service manual, you’re golden. For example, see Manitou Mast Parts Catalog for additional mast part breakdowns, or if you need the full workshop procedures, check Manitou Mast Components Parts Catalog. There’s also a massive 264-page catalog for the K-D Manitou MVT 1230L at K-D Manitou MVT 1230L MVT1230LC Parts Catalog – 264 Pages if you’re working on a larger machine.

One thing I want to hit home: this catalog’s illustrations are described as “general” – they may not show exact shape or detail. That’s not a flaw. That’s reality. If you rely on a third-party catalog that over-promises perfect drawings, you’ll get burned. The factory catalog tells you upfront: use the item numbers, verify with serial numbers. That’s how real parts ordering works. For background on diesel power plants common in these masts, this Wikipedia article on diesel engines gives a good primer, but don’t confuse engine parts with mast parts. The actual mast – the part that lifts – is what this catalog covers. For a deeper dive into diesel fundamentals, see this Wikipedia article on diesel engines.

Does this manual include torque specs for cylinder bolts?

No. This is a parts catalog, not a service manual. You need the separate Manitou service manual for torque values.

How do I know if my carriage is hook type or shaft notch?

Check the face bars on your carriage assembly – one end will have a stamped part number and model number. The catalog has separate sections for each type (pages 23-27). If you can’t find the stamp, look at the mounting method for the forks. Hook type uses a hook over the top bar; shaft notch uses a keyed shaft and retaining pin. The catalog diagram will match one of the two. Write down your mast serial number before calling to order – they’ll ask for it.

If you’re tired of ordering the wrong cylinder and wasting a week waiting for the right one, get the factory data. This isn’t a generic “one-size-fits-all” booklet. It’s the same parts breakdown that Manitou dealers use. Access the Factory Manual and start getting the part number right the first time.
