I'm working on a Class 1550 twin liner for a customer that has a few leaks on the rotating assembly that carries the rake arms. So far I've been able to get the seals where the arms leave the gearbox replaced, but am now trying to figure out how to get to the seals/O-rings at the bottom of the box where the other leak is occurring.
So far I have talked to two local dealers but neither has ever had one of them far enough apart to know what I need to take lose next. As it stands I've got the whole assembly removed from the rest of the machine. What I did was remove the top nut and pull the rotating assembly, along with the bevel gear, out of the housing that attaches to the rear arm on the machine. This leaves me with the bevel gear exposed at the top, and then the rotating assembly case right below it.
Looking in the parts book it looks like I can simply remove two more nuts (one that holds the assembly on, and another that allows the rear height adjustment) off and set the rotating assembly off the frame work where the wheels are.
The problem is none of us can tell form the parts book whether I can get to the lower O-ring this way, or whether the whole rotating assembly has to come apart to get to it.
I'm going to start back on it tomorrow, and see where I get, but I figured I'd post here first and maybe someone would be able to steer me in the right direction before I get deeper into it than I need to be to change the parts that need changing.
