How to Fix a Loose Pivot Pin on a Loader Frame: Step-by-Step Guide

Question:

The lower pivot pin on the loader frame is in poor condition, with noticeable fore/aft movement of nearly an inch. The upper pin, however, appears to be secure with no visible play. Splitting the machine to fix the pivot pin issue will likely require about two hours of work, along with additional time for adjustments and securing the loader frame and bucket. Using three piers to support the engine frame will make adjustments easier. Consider using a 60-piece o-ring flat face plug/cap kit from usadrivemotors on eBay to seal the hydraulics efficiently. While working on the machine, it's also a good idea to inspect and potentially replace the driveshaft, steering piston, and check the accumulators. If needed, a hydraulic shop can recharge the accumulators. If reassembly becomes challenging, consider renting a large Volvo excavator for assistance. Any helpful tips or precautions to keep in mind during this repair process?

Hello, I typically secure the front frame and utilize a loader or fork to carefully remove the rear frame. This method has proven to be more effective for me. Just my personal opinion. - Mark

I foresee the job being completed quickly, so I'm considering creating a time-lapse video using a GoPro camera just for fun.

It took 4 hours to complete the task, with a significant amount of time dedicated to preparing the work area and placing the blocks. Utilizing a flat faced o-ring fitting plug and cap kit helped minimize mess, as numerous buckets were used to catch any spills. A custom 2 3/4 hex wrench made from steel plate was necessary for removing the top center pin, which was successfully achieved with the assistance of a hydraulic jack. The lower center pin showed signs of wear with a 3/8 deep groove, and the lower bearing needed replacement. The engine frame side will require boring for optimal performance. For a visual recap, check out the six-minute time lapse video [insert link]. Overall, the project was a success!

I thoroughly enjoyed watching the video, featuring two men actively working while three others provided instructions. It was both entertaining and informative!

One user, oarwhat, expressed enjoyment for the video featuring two workers and three supervisors providing instructions, with a touch of humor. It seems like there's no such thing as too much supervision! Now, I have the opportunity to sneak down and use my spray gun to paint the interior of the front loader frame.
