Manitou MSI50H Parts Catalog – 24-Page OEM Mast Parts Index

Description

Look, I’ve been turning wrenches for 28 years. I’ve seen guys waste half a shift hunting down a part number because they grabbed some aftermarket catalog that had the wrong illustration. That’s why when I see a factory manual like this Manitou MSI50H Parts Catalog, I take notice. This is not a repair manual. It’s a parts identification book. It’s 24 pages of OEM illustrations and part numbers for the 2-stage mast on the MSI50H. If you’re trying to order a lift cylinder seal kit or a chain roller, this is the only source you should trust.

Manitou MSI50H Parts Catalog: What the 24 Pages Cover

Flip to page 4 and you’ll see the index. The manual breaks the mast into seven systems: RAIL SYSTEM, LIFT CYLINDER (section 1.00), CHAIN SYSTEM (section 2.00), HYDRAULIC SYSTEM (section 3.00), HOSE KIT RH (section 4.00), HOSE KIT LH (section 5.00), and CARRIAGE ITA TYPE (section 7.00). Each section has an illustration with item numbers, and a corresponding parts list with part numbers, descriptions, quantities, and the mast model. That’s how you find what you need without calling your dealer four times.

1.00 Lift Cylinder – The Core of the Mast

The cylinder assembly is the heart of the mast’s lifting ability. On page 4 of the index, the manual lists section 1.00 as LIFT CYLINDER. In the pictures, each component – barrel, rod, seal kit, wiper, piston – has an item number. Cross-reference that number in the parts list, and you get the exact Manitou part number. I’ve had guys try to order “universal” cylinder seals. Don’t. The OEM part for the MSI50H cylinder is the only way to guarantee the tolerances and pressure ratings. This manual tells you exactly which seal kit fits.

Why OEM Specification Matters for Parts Orders

The manual opens with a note: “The Mast parts are identified by an Item Number on the illustration or picture page.” It also tells you that the mast serial number is stamped on the identification plate on the right side of the outer rail at eye level. If you call Manitou North America (their number’s right there on page 1) and give them the mast model and serial number, they’ll confirm the part. Without the serial number, you’re rolling dice. Aftermarket catalogs skip this. The factory manual does not. Page 3 includes a sample of the identification plate and explains how to read the different part numbers for the mast, carriage, and optional equipment. That’s stuff you won’t get from a third-party reprint.

Does This Manual Cover the Hydraulic Hoses?

Yes. Sections 4.00 and 5.00 are specifically the RH and LH hose kits. If you’ve got a leak on the right side of the mast, go straight to page 4 of the index, find section 4.00, and look at the hose assembly illustration. You’ll see the part number for the complete hose kit or individual hoses. The same goes for the CHAIN SYSTEM (section 2.00) – chains, anchor pins, adjusters. And the CARRIAGE section (7.00) covers the ITA type mounting plate and fork stops. Everything you need to order is laid out with item numbers. No guesswork.

Three Systems You’ll Find Inside This Parts Index

First, the RAIL SYSTEM – the vertical channels that guide the mast. Second, the HYDRAULIC SYSTEM – cylinders and valves. Third, the optional equipment sections: 805951 SIDESHIFTER and 806848 FORK POSITIONER. The manual even includes a separate parts list for the optional Bolzoni sideshifter and Cascade fork positioner. If your MSI50H has those attachments, you’re covered. The manual is 24 pages total, so it’s not a novel. But it’s all you need to order the right part the first time.

FAQ: Quick Answers on the Manitou MSI50H Parts Catalog

Can I use this catalog to repair the mast?

No. This is a parts catalog, not a service manual. You need the factory service manual for torque specs and procedures. The Manitou MSI50H Parts Catalog – 30-Page OEM Factory Manual is the same type of document. For repair instructions, get the Operators Manual (Manitou MSI50H Operators Manual – 108 Pages of Factory Safety & Operation) or the full service manual.

How do I find the correct part number for the lift cylinder?

Go to section 1.00 (page 4 index). Find the item number on the cylinder illustration corresponding to the part (e.g., piston, barrel). Then locate that item number in the parts list directly after the illustration. The part number appears to the right. Double-check the mast serial number from the identification plate on the outer rail. If your serial number isn’t listed, contact Manitou Parts. The manual itself notes that the catalog is updated periodically, so verify with the dealer if your mast is a later revision.

Is this the same as the operator’s manual?

No. The operator’s manual covers daily operation, safety decals, and routine checks. This parts catalog is strictly for ordering replacement components. You can find the K-D Manitou MVT 1230L MVT1230LC Parts Catalog – 264 Pages for other models, but for the MSI50H 2-stage mast this 24-page book is the only correct source.

What if my mast serial number isn’t shown in the manual?

The manual states that if your parts are not found, contact your dealer or the Manitou North America Parts Department. Their number is on page 1. Provide the mast model (MSI50H) and the serial number stamped on the rail. The manual also says to check the upper portion of the cylinder barrel for a stamped part number. Use that information if your booklet is outdated. For general diesel engine operation related to the forklift’s powertrain, refer to this Wikipedia article on diesel engines.
