Bobcat 843b drive issue

[mike13_88]

hey guys joined this forum to see if I can get some help on a issue with a bobcat I have purchased. I have tried to make the bobcat drive but it barely moves and growls. put it up on jack stands everything works great goes front back side to side no noises. I am thinking clogged bronze filter? but cant seem to find it? any help to where it is on a 843?

Not sure if you have one but if it is like the 743 it will be on the left side of the pump standing in the bucket there will be a steal block with three hoses comming off the side it will be in the center hose in the steal block

Did some looking and the 843 does have the bronze filter under serial number 14999 if yours has it that is where it should be

so are the hoses going out to the left of the block? I cant remember for sure I think that's how it is. Hope I can get to it pretty easy. If I can I'll post pics when I get home thank you.

Thank you so it's the block under the cab not the one at the engine bay compartment? There is a ton of hoses under there and I'm not very familiar with hydraulics. I know theres a block under the cab but has a bunch of hoses connected to it I'll try and get a pic later

I do see a big black hose going to the left straight to the pump. I just got it I fixed a broken hose to the lift filled it up with super s universal oil for the time being just to see if I can get it going the guy I got it from said it pulled to the left wouldn't go right now it don't do anything but growl until you jack it up on stands
