Effective Techniques for Removing Lower Arm Bushings on a Takeuchi TL150

[MikePhua]

The Challenge of Stuck Bushings
Mechanics working on the lower arm of a Takeuchi TL150 often face extremely tight-fitting bushings—designed to withstand years of heavy-duty use. Traditional tools can struggle; these bushings may not budge even when hit with heavy sledgehammers. Their firm fit necessitates controlled force and clever tactics to avoid damaging the arm assembly.
Method: Chain and Porta‑Power Strategy
One effective method involves using a ratcheting binder chain to draw the two lift arms together, paired with a 10‑ton Porta‑Power hydraulic spreader placed between them. This combo creates focused pressure that can gradually push the old bushing out and simultaneously draw a new one in. Light taps on the outside of the arm assist alignment and ease movement.
Homemade Puller Technique
Another successful DIY approach involves crafting a makeshift puller using:

• A long bolt (around 7–8 inches; ¾″ or 1″ diameter),
  
• Washers sized to fit inside the bushing bore,
  
• A pipe to guide the bushing outward.
  

By threading the bolt through, sandwiching the old bushing between washers and the pipe, and using a heavy-duty impact tool, the bushing can often be worked free. Several mechanics report success with this gradual and controlled method, though the tight fit requires patience.
Video Demonstration & Homemade Press Jigs
Visual learners may appreciate demonstration of similar techniques—particularly a homemade jig used to press pins and bushings on related models (like the TL240) using a portable hydraulic press or homemade setup. While not specific to the TL150, such visual examples offer clues for replicating the approach.
Key Terms and Concepts

• Porta‑Power: A compact hydraulic spreader capable of delivering several tons of pushing or pulling force—used here to push bushings out.
  
• Ratcheting binder (chain): A tensioning chain system that draws components together tightly and securely.
  
• Makeshift puller: A rig built using a threaded bolt, internal washers, and a guiding pipe—used to pull bushings out without special tools.
  

Story from the Yard
Imagine a service technician working late under job-site lights. Frustrated by a bushing that won't budge, he rigs the TL150 arms together with a chain, slides in the Porta-Power tool, and applies steady hydraulic force. The arm groans under pressure—and suddenly, with a satisfying pop, the worn bushing slides free. He follows up with the washer-and-pipe puller to install a fresh bushing. Minutes later, the machine is back in alignment, ready for its next task.
Step‑By‑Step Guide

• Secure the arms using a ratcheting binder or chain to prevent spreading during removal.
  
• Position a Porta‑Power (10‑ton hydraulic spreader) between arms, gently applying pressure to coax the bushing out.
  
• Add light sledge taps around the bushing area for improved alignment and movement.
  
• If needed, build a homemade puller: bolt, washers, pipe guide, and impact tool to thread out the bushing gradually.
  
• Always use a replacement bushing immediately—waiting can cause movement, corrosion, or misalignment.
  

Summary of Approaches

• Chain + Porta‑Power Method: Align and press bushings out with controlled hydraulic force and a tethered chain.
  
• DIY Puller Method: Threaded bolt with internal washers and external pipe to mechanically extract the bushing.
  
• Visual Guides: Adapt ideas from videos demonstrating hydraulic presses and homemade jigs.
  

In conclusion, while lower arm bushings on a Takeuchi TL150 can be stubborn, a combination of chain tensioning, hydraulic pressing, and homemade puller tools provides a reliable path to removal—without risking damage.
