Hello all - I signed up to this site some time ago when I bought my 853 but I don't think I ever posted much. The machine has been awesome and I use it frequently for small jobs on the property, however I started to notice that 2 of the wheel seals were bad and I knew I had a bad bearing on the left front, so I know have the machine in my shop attempting to put all new bearings into it. I have to say that this has been a learning experience in a big way, I had to use 2 bottle jacks to get the 2 hubs off that I have removed thus far. I am currently working on the front left but I have some general questions; 1. is there a special tool or design of tool to remove the outer bearing races? I read on here where someone was saying to lay a weld bead on the race and it will shrink up and come out which is interesting. I removed one by cutting it and then "shocking" it with a chisel, it worked but not my favorite method. 2. how the hell do you torque the sprocket bolts anywhere near the 450-575 ftlbs the manual states? Working on the front is bad enough to loosen but I can only imagine what a nightmare the rear is going to be and I cannot imagine how to get them as tight as the manual calls out. 3. I've read where people are saying to use motor oil in the chain case verses hydraulic fluid, seems to me that as long as there is some type of lubrication in there its good? 4. in there a belly pan drain? I know there is a drain for the chain case but I seem to have some fluid beside (or maybe under) it. Something is leaking in there and I am not sure what but I intend to go around and tighten everything I can find. Whatever is leaking is doing so slowly, sometimes the fluid level is good and then the next time it is barely on the stick. 5. (random question) are the exterior hydraulic fittings (like where you hook up an accessory) 1/2 NPT lines? I still have Pioneer fittings and I am not a fan as they leak horribly when I am using my backhoe attachment Thank you in advance for any assistance.
