2004 J Deere 27C ZTS Mini Ex - Any guidance on stopping Front Idler Bushing Wear

I was wondering if anyone out there has done a retrofit to their front idlers on a mini excavator to add lubrication. I bought my machine with 1444 hours on it, and soon after realized that my yolks, bushings, idlers and pins were completely destroyed from wear. I had to completely replace both sides for a pretty hefty price in parts.



Please share any ideas.

Thank you,

Bobby
