BRONZE SLEW RAM BUSH SUITABLE FOR JCB 3CX, 4CX - 808/00388

Technical Specification and Compatibility

A high-quality slide bush, made of a special bronze alloy. It is a key component of the slew ram joint, mounted in its eye. Its function is to provide smooth rotational movement for the pin and to bear the enormous forces generated during the slewing of the backhoe arm, minimizing friction and protecting more expensive components (the ram eye, the carriage) from wear.

Part number: 808/00388
Alternative part numbers: 332/G0942
Manufacturer: CORESPEX
Dimensions (mm): 90 (outer dia.) x 75 (inner dia.) x 34 (height)
Material: Bronze

A CORESPEX brand product – premium quality replacements that guarantee long life and reliability, even when working in heavy-duty conditions.

Service Recommendation: Ensure Maximum Lifespan

For a comprehensive and durable repair, always replace slew ram bushings in a set with new pins and seals. Regular greasing of the joints with high-quality HYPTRON grease containing molybdenum disulfide (MoS2) drastically extends the life of the bushings.

Part's Role in the Machine and Failure Diagnostics

Bushings are sacrificial components designed to wear out to protect much more expensive parts like the ram eye or the sideshift carriage. Ignoring worn bushings leads to play, which in turn damages the pin bores (causing them to become oval), ultimately requiring a very expensive re-boring repair.

Replace the bushings if you notice:

  • Excessive play (clunking) on the slew ram pins.
  • "Jerking" or shuddering when starting or stopping the arm's slew.
  • Loud squeaking or grinding from the joints, even after greasing.
  • A visible crack or displacement of the old bush.

Peace of Mind Guarantee: Why Choose Our Offer?

✓ Restore Precision and Rigidity: Choose CORESPEX

Play in the arm means a loss of precision and faster wear of the entire machine. As a leader in the supply of pins and bushings, we guarantee a perfect fit and the highest quality material. CORESPEX bushings, made of bronze with optimal sliding properties, will restore your machine's factory rigidity and precision, which translates into work efficiency.

Expert's Guide: Key Installation Tips

  1. Check the bores: Before pressing in new bushings, thoroughly clean and inspect the bores in the ram eye and carriage. If they are worn oval, they need to be re-bored.
  2. Use a press: Use a hydraulic press with appropriate sleeves to install the bushings. Hammering them in can cause damage.
  3. Align grease channels: If the bush has grease holes or channels, make sure they align with the grease nipple after installation.
  4. Grease generously: After installation, pump in a large amount of fresh grease until it purges out, removing any contaminants from the assembly process.

Frequently Asked Questions (FAQ)

1. Why are the slew ram bushings made of bronze?

Bronze bushings are used in very high-load, low-speed joints. Bronze has excellent sliding properties and is more resistant to seizure in the event of a temporary lack of lubrication than a steel bush, which is crucial in such an important component as the backhoe slew mechanism.

2. I have play on the pin, but the old bush looks okay. Do I have to replace it?

Yes. Even if the bush is not cracked, the play indicates that its internal diameter has worn. Installing a new, tight pin in an old, worn bush will not eliminate the play and will lead to rapid wear of the pin. Both components should always be replaced at the same time.

3. What are the risks of working with worn slew ram bushings?

Prolonged operation with loose pins causes the bores in the ram and sideshift carriage to wear out. The holes become oval, and their repair is very expensive and requires specialized machining (a mobile line boring machine). It can also lead to damage to the ram seals.
