Newbie.. 843... Questions

[workinprogress]

Hello all! Great forum! I have searched many things and found the answers to my questions before I even ask them! My Father and I had been looking into picking up a Skid Steer for quite a while when we stumbled upon this Bobcat 843 on craigslist. After taking a look at it, it needed the seals in the control valve replaced, a leaky lift cylinder fitting fixed, some new tires, seat, the usual stuff from what I have read here... But we picked it up for a mere $4300 so it was worth the money (I think?) We pulled the control valve and replaced the seals (I'll pay someone to do that if it ever needs done again, and I am a Nuclear Power plant Mechanic by trade, and that job is a pain in the a*)... But now it works great and no more leaks there. Replaced the foot pedal bushings to get the pedals working better, and noticed that the bushing on the center of the crossover bar for the boom pedal (that goes under the pumps) has a worn out (1/2" of play) bushing. My question: Is the bolt that holds the bushing and crossover bar threaded in (or simply pass through) from the inside of the chain-case? If it is, will I have to lift the pumps in order to remove the crossover bar and bushing? If it is not threaded, what is the possibility of reaching the bolt through the access cover under the brake pedal? If anyone has any insight or pictures of the crossover bar with the pumps removed it would be greatly appreciated! The Parts and Service Manuals do not answer these questions! Also, is there anything about owning an 843 that I should know? I am a newbie and open to learning all that I can about these things!

Sadly yes, the pump needs lifting up to get to that bushing/bolt.....
The only other way is to disconnect the linkages and the bolts holding the front of the pump to the chain case. Then the bolts holding the chassis to the chain case and jack it up to gain access to the arm. You may not have enough length in the drive motor hoses too, so they mey need disconnecting too.

Ok, that is what I thought. Thanks for confirming that. The nut is on top thankfully and I can access that by reaching under with a wrench, but is the bolt threaded into the chain case from the bottom side or is it simply a drilled hole that the bolt passes through?

I would hate for the bolt to fall into the chain case and have to go fishing for it. It seems to be staying tight when I take the nut loose, but I hate to assume that it is a threaded hole and it not be!

The bolt screws upwards through the chaincase. The hole is threaded, so HOPEFULLY it is not stripped by the previous owner, i highly doubt it is. So you really should have no issues removing the nut, arm and bushing and putting it back on.
