modified push rods for mini excavator

I have a solution for the lack of power to the boom. I put a threaded sleeve in instead of a nut, and it works 100 times better. This is the Amazon part https://a.co/d/fd4jevk. M4x0.7mm Female Thread 15mm Threaded Round Sleeve Connector Rod Bar Stud Tube Nut. Insert the sleeve nut into the push rod linkage and add some superglue if the fit is loose where the old nut slot is. then assemble like normal after that.
