A high-quality slide bush, made of hardened steel. It is a key component of the joint that connects the kingpost to the sideshift carriage. Its function is to provide smooth rotational movement for the kingpost pin and to bear the enormous forces generated during backhoe operation. Precision manufacturing is essential to eliminate play and protect more expensive components from wear.

The list above is for reference. It is crucial to ensure that your machine has the older sideshift type with a rack and pinion slew mechanism.
For a complete joint refurbishment, always replace the upper bushings together with the lower ones, and with new pins and seals. Regular greasing of the entire kingpost with high-quality HYPTRON grease with MoS2 additive drastically extends the life of all moving parts.
Bushings are sacrificial components designed to wear out to protect much more expensive parts like the kingpost 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:
Ignoring play on the pins leads to irreversible damage to the bores in the carriage and kingpost, forcing costly re-boring repairs.
A repair performed using a complete set of GX-AFTER pins and bushings is the cheapest way to avoid these problems. Secure your machine and restore its factory precision – order a complete set today.
Play in the backhoe can come from many places. This bush eliminates play at the upper kingpost mounting to the carriage. You should also check the lower kingpost mounting, the slew ram pins, and the pin connecting the boom to the kingpost. A comprehensive repair requires replacing all worn bushings and pins.
2. How do I distinguish the "old type" of slew from the new one?The "old type" of slew, used until about 1997, is based on two hydraulic rams and a rack and pinion system. Newer machines use a slew ring system (like in large excavators), which has a completely different kingpost and carriage design.
3. What happens if I keep working with worn bushings?Prolonged operation with loose pins causes the bores in the arm, kingpost, or ram to wear out. The holes become oval, and their repair is very expensive and requires specialized machining (a mobile line boring machine). Replacing bushings in time is the cheapest way to avoid this failure.
