First I spent about 2 hours trying to figure out the orientation of the lines to the steering cylinder. Once something made sense, I rolled with it. As you can clearly see, they are inside the frame. Take care to look for any moving parts, or areas that could damage the lines. I dont know if this was the correct way to install the lines in this instance? Bolens seemed to have made them both ways with lines run inside the frame, and outside the frame, but this way worked for me.
Second, was finding out what line was pressurized, I unscrewed the right line at the pump first, then cranked the engine without starting it, and shure nuff Bingo, she squirted oil, so thats my port to run to the steering first. Listed in order of proper connection, pressurized port to steering, steering to spool valve, spool back to hydro.
Once that was somewhat handled, it was a matter of unbolting parts, and replacing them on the linkage.
After that was completed, it was time to make the final line connections by the pump. I was missing the double ended flaired fitting to connect the loop together. So, off to Napa. Napa didn't have exactly what I needed, so I had to make a couple of fittings work. The thread size is 9/16" 18 pitch hydro threads. Obviously some tweeking of the lines was in order to get a final fit, but it works. Please note the picture where the steering return line is looped to the spool feed line. These 2 lines have to be either inside the frame, or just above the frame!!! This is crucial as there is not alot of clearance here once the rear pan is installed! Several test fits of the rear pan maybe needed. This is also a good time to spin the driveshaft by hand to be sure the fan is clear of obstruction.
Once it was together before I even got to start it up to check 4 leaks wouldn't ya know drip drip drip. SOB!!!! Had it all together, and here one of the lines was worn, and cracked from the previous machine. Ok, went to Napa, and they were no help AT ALL. So, I thought what the hell, it's thick tubing, Ima try welding the SOB, and filing the welds down by hand. Unbelievable, it actually worked!!!! Put the line back in, and BAM, DONE!
You're milage may vari
