Hi guys, I am new to the skid steer game but I picked up a 743 (serial #501924608) for cheap. So with the cheap came some issues. I Have been working on it whenever time allows and trying to get it running a little better. Being new to skid steers I have a couple probably basic questions… 1.I know that the hydraulic resv is to either have a dipstick, sight glass or pet cock. I cant find anything. Im thinking that at one time made there was a sightglass and the previous owners may have put in a regular bolt as replacement. Should I replace this bolt with a sight glass to have some guage 2.I have two couplers next to the seat inside the cab. I have no idea what they are used for. 3.Should I replace my quick connects with flat faced 4.my bob tach is sloppy and the bushings need replacing. My question is the bushings were the tilt cylinder meets the bob tach are they weld in. BC they way they look now it doesn;t appear that they are but this could be bc they are that far worn. Also I feel like the pin is too short that runs through the bottom of the tilt cylinder through the ears of the bobtach. Do you think its bc the ears are that wallowed out or.. 5.The wedges that run through my bobtach have no levers. I assumed this is becomes they never changed buckets and it appears the rust locked the wedges in enough that they had no need lock them. Im guessing heat/pb blaster to break the wedges free and add some levers so I can change attachments. Im going to hopefully add pictures to the post so you guys can see what im talking about. Thanks in advanced.
