New Holland 37 1975 Parts Catalog – Factory Parts Breakdown for 37 Forage Harvester

If you are working on a New Holland 37 1975 Parts Catalog is the original OEM publication – 45 pages of exact part numbers, exploded diagrams, and ordering instructions. Aftermarket cross-references will get you into trouble when you need a P.T.O. yoke or a specific bearing for the cutterhead. This catalog came from New Holland’s own print run in 1975. It covers the 37 Double-Chop Forage Harvester, both UK and export variants. Skip the guesswork – use the factory list.

New Holland 37 1975 Parts Catalog – Factory Specs for Forage Harvesters

Every group in this catalog is organized by assembly. The table of contents lists 24 sections, from the front P.T.O. assembly (page 2) to the spout extension and safety shield (page 35). Each section includes exploded-view line drawings with numbered callouts. You match the callout to the parts table – part number, description, and quantity per machine. That is how you confirm you have the right component before you place an order.

45 Pages of Detailed Parts Identification

45 pages of OEM data. Page 2 shows the front P.T.O. assembly complete with part number 158323 for the whole unit – includes items 1 through 16. If you need a journal bearing and circlip assembly, that is ref. 7, part number 51647. For the yoke shaft assembly, ref. 9 is 51654, but pay attention to the note: if the machine has a lemon-type shaft, replace with items 9, 10, and 11 as listed. This level of detail only exists in an OEM print. Aftermarket copies leave out those footnotes.

What Systems Are Covered in This Catalog?

Hydraulic lift group, gearbox group, cutterhead drive sheaves and idler group, fly wheel group, rotor group, auger group, discharge spout group – all are inside. The catalog also covers the hydraulic hitch assembly in three sections (intermediate, completion, and full assembly). For machines with axle extensions or wheel repositioning kits, those pages are included too. UK machines and export machines get separate tongue and spindle groups because the spindle bearings and U-bolts differ. If you are working on an export model, note the fixed P.T.O. guards that require chain part number 158171 (page 2).

Ordering Parts: Follow the Factory Instructions

Page 2 of the catalog contains the official ordering protocol. Give the model and serial number. Write the complete part number and description. Understand that left and right are from the operator’s seat facing forward. Specify shipping details – rail, road, or air. Sperry New Holland reserved the right to make improvements without obligation to update older machines, so always verify the part against your serial number range. This is how you avoid getting the wrong yoke or a mis-sized bearing.

P.T.O. Assembly and Rear Bearing Support Group

The front P.T.O. assembly (page 2) lists every component down to the tension pin (ref. 11, part 51656) and the slotted headless set screw (ref. 14, part 51575). The rear P.T.O. and bearing support group (page 5) includes the twine guide U-bolt (ref. 1, part 28114). Two sections cover the full driveline. If you need to rebuild the P.T.O., these pages give you the exact OEM numbers – no aftermarket substitution required.

Does this manual include torque specifications?

No. This is a parts catalog, not a service manual. It lists part numbers and diagrams only.

How do I identify the correct part if I have a UK machine versus an export machine?

The catalog includes separate sections for UK machines (page 4) and export machines (page 31) for the tongue and spindle group. Also check the P.T.O. guards – export models require fixed guards with chain part number 158171. Always verify the model serial number and compare with the part description. If you have a lemon-type shaft on your machine, refer to the note on page 2 regarding replacement of yoke shaft assembly. Using the wrong variant can cause driveline failure or safety hazards.
