CNH CX240B 2008 Repair Manual – What You Actually Need on the Bench

Let me tell you straight: I’ve seen guys launch a grease cylinder plug across a shop floor because they loosened the check valve too fast. That’s a 3000 psi grease gun with a steel plug – it’ll take a tooth out if you’re in front of it. The CNH CX240B 2008 Repair Manual I’m talking about here is the factory-issued book for the track removal and installation procedure. It’s 50 pages, published March 2008 by CNH France, and it doesn’t leave room for guesswork. If you’re working on an excavator track and you don’t have this, you’re risking injury and wasted time.

Removal of Shoe Assembly: Procedure on Page 3

Page 3 walks you through the shoe assembly removal from start to finish. First, you rotate the track so the master pin is next to the idler. Then you grab a 19 mm box wrench and loosen the check valve a little bit at a time. That’s where the danger lives. The manual says: “Do not loosen the check valve all at once.” It tells you to monitor the grease output and use a rag to catch the trickle. If you crack that valve open too fast, the plug flies off and you’re bleeding. I’ve had guys argue that they can “feel” the pressure drop – that’s how you get hurt. The manual gives you the exact sequence; follow it.

Installation of Shoe Assembly – Torque Specs on Page 6

Installation is covered on page 6. It’s not just reverse of removal; there are specific clearances and bolt patterns you need to respect. The manual lists the torque values for the shoe bolts – something aftermarket PDFs often skip or round up. I’ve seen stripped threads from using generic 150 ft-lb when the factory says 120 ft-lb. This manual gives you the real numbers. For a CX240B, the track tension is set by the grease cylinder; the manual tells you how to pump it back to spec without over-stretching the chain.

Shoe Plate Replacement: What’s on Page 8

The shoe plate itself has its own section starting on page 8. If you’ve worn down grouser bars or cracked a plate, you need this. The procedure covers removing the plate bolts, separating the plate from the chain, and installing the new plate with the correct bolt orientation. The manual includes a note about which side of the plate faces the roller – it matters for wear life. You don’t get that in a generic YouTube video.

1 Critical Warning You Cannot Skip

The manual has a specific caution that I want to emphasize: “Do not get under the main unit when it is jacked up. Make sure to place the main unit on crossties to prevent falling.” That’s on page 3, right after the check valve warning. When I train techs, I make them read that paragraph out loud. Track work involves lifting the machine; one hydraulic jack failure and you’re crushed. The manual doesn’t assume you know this – it spells it out because CNH engineers have seen the accidents.

Why This 2008 Repair Manual Beats Aftermarket Copies

I’ve wasted hours on third-party “repair manuals” that claimed to cover a CX240B but had torque specs that belonged to a different model year. This is a 2008 factory print from CNH – the same one the dealer techs use. The document is 50 pages of pure procedure, no filler. It’s scanned from the original binder, so the diagrams are crisp. You can zoom in on the master pin alignment graphic and see the exact orientation. Aftermarket reprints often blur that detail, and then you end up with a track that walks off the rollers. Not here.

If you’re used to working on a Manual Transmission, you know that procedure matters. The same rigor applies here. Don’t treat track work like a Manual Transmission clutch swap – it’s a different beast. This manual gives you the specific greasing distances, the pin removal sequence, and the torque pattern.

Does this manual cover the entire CX240B machine?

No, it focuses exclusively on track removal and installation – shoe assembly, shoe plate, and tensioner procedures.

How do I safely release the track tension using this manual?

Follow the procedure on page 3: use a 19 mm box wrench, turn the check valve slowly while monitoring grease output with a rag, and never work in front of the valve. The manual warns that the cylinder pressure is extremely high. After releasing the tension, remove the master pin with the engine off and the machine supported on crossties. Do not jack the machine without blocking it – that warning is bolded for a reason.
