Manitou MSI50H Parts Catalog – 30-Page OEM Factory Manual

I’ve been twisting wrenches for 28 years, and I’ve seen more aftermarket parts books that couldn’t find their own ass with both hands. This Manitou MSI50H Parts Catalog is the real deal – 30 pages of factory-issued breakdowns for the 3-stage mast. You don’t guess part numbers on a forklift mast. You pull the right one, or you end up waiting three weeks for a return. This manual came straight from Manitou North America, Inc., Waco, TX. That means the exploded views match what’s bolted to your machine, not some illustrator’s idea of what a cylinder looks like.

Primary Cylinder and Secondary Cylinder: Find the Right Part Number

Section 2.00 covers the PRIMARY CYLINDER, and Section 3.00 covers SECONDARY CYLINDERS. You need a replacement for the barrel? The manual tells you where to look for the stamped part number – along the upper portion of the barrel. I’ve had guys call me asking which seal kit fits; I tell them to pull the numbers off the cylinder itself, then cross-reference to the illustration. Page 4 (Index) shows the exact chapters. If you skip that step, you’ll order a kit for a different mast series. That’s lost time and money.

7 Systems Covered: Rail, Chain, Hydraulic, and Hose Kits

The table of contents lists 7 major systems beyond the cylinders:
1.00 Rail System – the entire upright structure.
4.00 Chain System – load chains and sheaves.
5.00 Hydraulic System – lines and components.
6.00 and 7.00 Hose Kits – single function right-hand and left-hand.
8.00 Carriage, ITA Type.
9.00 Decals – placement and part numbers.
10.00 Sideshifter, 40 in.

Each section has its own parts list with item numbers, descriptions, quantities, and the specific mast model that part fits. The manual even warns you: “Because of the multitude of Mast Models and components utilized, the illustrations provide a general description and therefore may not show the exact shape or detail.” That’s honest. But the part numbers are correct if you verify your mast serial number.

Does This Manual Cover the Sideshifter Assembly?

Yes. Section 10.00 covers the SIDESHIFTER, 40 IN. The parts list also references three slide-on sideshifter assemblies: AR5832 (40″ TILL/S DECK), AR5833 (48″), AR5834 (54″), plus an AR6059T18 Slider. If your MSI50H has a sideshifter, you’ll find the mounting parts and cylinder brackets here. The manual also includes a GENERAL INFORMATION page (page 3) explaining how to read the illustrations and where to find the mast serial number – right side of the outer rail, at or above eye level. Write that number down before you call for parts.

Who Needs This Manual? DIY Mechanics and Fleet Owners

If you run a shop that services Manitou forklifts, or if you own an MSI50H and want to rebuild the mast yourself, this 30-page parts catalog is the reference you need. The aftermarket parts diagrams you find online often skip the primary cylinder details or mix up the chain system parts. With this OEM document, you have the factory breakdown. It tells you the quantity of each part required – for example, how many rollers per rail, how many chain segments. No guessing. I’ve seen guys order two secondary cylinders when the spec calls for one per side. Avoid that headache.

Source Validity: Why OEM Beats Aftermarket

This is not a third-party compilation. It’s the original Manitou Parts Manual, catalog number 806878, revision R07-06. The mast model series is 805358. The copyright belongs to Manitou North America, Inc. When you order parts using this catalog, you give the dealer the mast model number and serial number directly from the identification plate. The manual even warns: “If your forklift Model or parts are not found in this manual, please contact your dealer or the Manitou North America Parts Department.” That’s the level of traceability you don’t get from a generic PDF slapped together from internet scraps. For more context on the diesel engines that power these lifts, you can check this Wikipedia article on diesel engines, but for mast parts, stick to this catalog.

How do I confirm the correct parts for my mast serial number?

Write down the mast model number from the identification plate (right side outer rail) and the mast serial number. Then find the illustration in the manual, locate the item number, and order the part number listed. If the catalog doesn’t have your serial range, call Manitou Parts Dept. at 800-425-3727.

Does this manual include torque specs for the cylinder bolts?

No. This is a parts catalog – it shows exploded views and part numbers, not torque values. For tightening specs, you need the service repair manual.
