Case 150, 190 1972 Parts Catalog

If you’ve ever ordered a part for an old Case garden tractor from a third-party source and ended up with a water pump that doesn’t bolt up, you know the frustration. I’ve been turning wrenches since before some of you were born, and I’ve seen more wrong parts returned than right ones installed. The Case 150, 190 1972 Parts Catalog ends that headache. This isn’t a reprint of someone’s photocopy – it’s the factory book, printed in 1972, with exploded views that match the actual hardware on these tractors. You get the part number, the grid location on the page, and the exact description. No guessing.

Grid coordinates remove the guesswork.

Engine Section: Camshaft, Crankshaft, and Cylinder Block

The engine section of this 40-page Parts Catalog covers everything from the air cleaner to the flywheel. For the 150 and 190 models, the Camshaft is listed on grid A8, page 7, along with the crankcase breather and valves. The Crankshaft and Connecting rod group spans pages 9-11, grids A10-A12. If you’re rebuilding the Cylinder block or head, those assemblies are on pages 13-15, grid A14-B2. Each part has a reference number that ties to an exploded illustration. You won’t find “compatible with” nonsense here – only OEM Case numbers. Need a gasket kit? Same pages.

Electrical System: Grids D10-D12

The Electrical section covers the battery, spark plug, headlights, and instruments on pages 51-53. This is critical for a tractor that’s sat in a barn for decades. The factory called out the correct battery group size and terminal layout. You also get the starter-generator belt routing on page 25, grid B12. Aftermarket catalogs often list a universal belt length that forces you to shim the alternator. Not here. Automotive Industry Overview shows how manufacturers standardize these specs – this manual follows that standard.

Basic Tractor: Hydraulics, Transmission, and Steering

The Basic Tractor section covers the front and rear axles, steering gear on page 27, and the transmission on page 33. The hydraulic system gets 6 pages (35-41) with exploded views of the pump on page 37, control valve and linkage on page 37 and 38, hoses on page 35, and the hydraulic drive motor on page 39. If you’re troubleshooting a lift that won’t hold, you need the part numbers for the valve spool and seals. The grid system on page 2 explains how to locate any part within seconds. This catalog was designed for a parts counter guy in 1972 – it’s efficient.

Why OEM Grid Coordinates Beat Aftermarket Scrambling

Aftermarket parts catalogs often list generic part numbers that cross-reference to multiple brands. That works about 70% of the time. But when you’re rebuilding a Case 150 or 190 engine, you can’t afford a camshaft that’s “close enough.” The Camshaft on page 7 is listed with a specific Case part number, and the illustration shows the lobe orientation. The Crankshaft on page 9-11 includes the keyway dimensions. The Cylinder head gasket set on page 13-15 is a factory kit. This manual saves you the return shipping costs.

Get the Right Part Number Every Time

The alphabetical index at the front of the catalog lists every major group – Engine, Electrical, Hydraulics, Transmission, etc. – with a page number and grid coordinate. For example, “Cylinder Block” points to pages 13-15, grid A14-B2. Flip to that page and you’ll see an exploded view with reference numbers. Each number corresponds to a row in the parts list with the Case part number, description, and quantity. If you need a battery, go to “Battery” in the index – pages 51-53, grid D10-D12. Simple.

What About the 150 and 190 Differences?

The catalog covers both the Case 150 and Case 190 garden tractors. The serial numbers are noted on page 2. Some parts are specific to the 190’s larger engine. The Parts Catalog flags those differences in the description. For instance, the PTO front clutch (page 23) may have different pulleys depending on model. You need the correct pulley for the belt alignment. The 1972 publication date means these were the latest revision parts at that time. Later revisions may have superseded some numbers, but this is the original listing. You can cross-reference with Case dealer system if needed.

You may also need Case CX160B 2007 Parts Catalog – OEM Undercarriage Hydraulics for larger machines. Case CX27B 2007 Parts Catalog – OEM Factory Specs for Mini Excavator and Case CX40B 2010 Parts Catalog – OEM Factory Spec Data are available for newer models.

FAQ

Can I use this catalog to rebuild my Case 150 engine completely?

Yes. It covers the cylinder head, camshaft, crankshaft, piston, connecting rod, and all related gaskets. Exploded views show part placement.

Does this parts catalog include repair procedures or torque specs?

This parts catalog does not include repair instructions or torque specifications. It is strictly for ordering correct OEM parts. If you need service procedures, you’ll want a separate service manual. However, having the exact part numbers prevents ordering wrong components. Many DIYers assume a gasket set from a generic supplier will fit, but the 190 uses a different head gasket than the 150. This catalog tells you which is which. Also, the grid system helps you identify small parts like seals and o-rings that are often omitted in aftermarket listings. So for engine rebuilding, this catalog is essential for the parts ordering phase, but you’ll need a workshop manual for the assembly steps.

Don’t waste time with photocopied parts lists that may have been scanned upside down. This is the genuine Case factory Parts Catalog from 1972. You get 40 pages of exact part numbers, exploded views, and grid coordinates. Whether you’re restoring a Case 150 for show or keeping a 190 running for mowing, this manual gets the right parts on your bench. Access the Factory Manual and start ordering correctly.
