I need a little help adjusting the stop on the hydraulic unit. I have the instructions from the servicman's handbook right in front of me. First it tells me I need a pressure guage (one that reads high pressures) for making the adjustment. Well, I know many of you have rebuilt your hydraulics with much success. Do each of you have a pressure guage? If not, how did you adjust the stop?
Here is a little background information. My first Cub was a 1951 which I used for mowing grass and plowing snow in the winter. The motor in it is running on borrowed time, just plain tired. I not could afford the downtime for a rebuild, so I bought a 1963 to take over the chores.
On my 51 the snow blade (54A) worked perfectly. In the up position there was plenty of ground clearance. When installed on my 63, in the up position, the blade barely comes off the ground. The previous owner(s) of the 63 didn't know what they were doing when it came to some of the repairs that were done and I'm certain that this is the case with the stop on the hydraulic unit. The way I see it, the stop will ultimately control the position of the rockshaft which in turn will have an effect how high the plow blade is raised. I just want to verify that stop is properly set.
Any help/suggestions would be greatly appreciated!

Rebuildign the hydralics is not a big challenge as long as you remember clean, clean, clean. You can adjust the stop without a gauge by listening carefully for when the pump is under load or not under load. Most farm supply stores sell pressure gauges for 7 or 8 doallars that will work. Look in the pressure washer department. They will be a higher pressure gauge than is necessary, but will do the job. You will also need a nipple and coupling to get enough clearance for the gauge.
If you are not part of the solution,
you are part of the problem!!!

Peter. It could be something simple such as all your connected parts. Is it on the best place at the rocker arm? I made the mistake once of connecting the blade to the top hole in the lift bracket (with the spring) instead of the bottom hole. Made more of a lift difference than I would have thought..........

John, I'll give the farm supply store a try. If they don't have a guage I'll try it by ear.
Ron, I know what you're saying, but that's not the case here. There is just a big difference from the 51' to the 63' using the same exact setup. I know that the stop on the hydraulic block on the 63' had been messed with, that's why I'm hoping resetting it will give me the proper amount of lift.
Thank you both for your suggestions.
