[QUOTE="baxter, post: 64894, member: 8988"] Hello, I have a 2001 Bobcat 331 (2050 hours) with a hydraulic leak on the final drive assembly. It is sweating fluid out of one of the allen bolts on the relief valve (very top of the final drive assembly). It loses about a 1/2 gallon every 4 to 5 hours working time. This is the block that is bolted onto the main valve block. Is this just a leaking / bad oring somewhere to have it leak out of one of the allen bolts? I would think it should leak out of the block body but might be taking its easiest route out. I also think there is 2 orings isolating the 2 ports beween the relief valve and main valve bodies. Any help, thoughts, or comments would be grateful. [/QUOTE]
