I have mine apart right now. I added the drain plug where you indicated but I also added a second one in the "gear side" chamber. There is a separation of these two chambers and they cannot both drain through one hole when the unit is in the normal upright orientation on the mower. They can both drain when you tip it over on the bench but not when its installed. Good video and thanks for making this.

I’ve rebuilt a few of the and the same thing with the springs I suspected water as well. Just tonight was rebuilding the left side on the exact noble in your video. Reinstalled it and it ran backwards. Your right about that block going in either way had to tear it back down and turn the block 180. All the right side ones are the opposite of this. I hook the tension spring up first then just walk it onto the pulley. Pretty easy that way. Thales for sharing this it helped me out.👍

Really appreciate the comment. Isn't it a sickening feeling when you spin it the first time after the RTV is all set up, job is almost done, and you realize it's going backwards? Definitely been there. Interesting tip on installing the spring first and rolling the belt on afterwards, I'll have to try that next time!

Mine went backwards too! What a PITA doing it twice! Glad to share the misery with you fellas.

That wire hack is awesome for them springs 👍🏾

Hi there, thanks for the comment. I've used this trick often on heavy deck tensioning springs as well. It keeps you out of the line of fire, such as being underneath the machine prying on these loaded parts with screwdrivers or prybars, etc... Helps avoid broken fingers! It also lets you pull with a lot more force if you can brake a knee or something on the frame, deck, etc... Work safe, everyone!

@@StevesFarmShopalso liked the wire hack CHEERS. Here’s a wiring lesson always stack ring terminals to a stud like a pyramid with the smallest at nut at the top just basic wiring usually overlooked thanks

Thanks for this video. It really helped me put back my transmission easier. But i had a problem when i got it all back together. I got all new springs and the block that the springs go back into. It fixed the issue i had which is before it barely had power to climb up a small hill.. now it’s perfect and the power is back to it, BUT… when i go reverse, i barely had any power. Do you know what the problem could be?? Any help from anyone will be much appreciated.

Glad the video helped, sometimes I question whether it's worth the time to make these. If you jack the rear of the mower up and run the propel forward and reverse, do you see normal reverse wheel speed unloaded in the air? If it's slow in reverse with no load, I wonder if it's something obvious in the linkage, getting hung up so you're not getting full pump swash in reverse. Does the handle move all the way in reverse normally? If speed looks normal in the air but then it's slow in reverse under load, that sounds more like belt slip or some sort of internal leakage (pressure based leakage). Does the engine load down in reverse or do you hear basically no laboring? This could give you an idea of how much HST pressure is being built. This was the first one I've done and it worked OK in both directions. It did take a pretty long time to bleed the first time. Do you think you ran it long enough to completely bleed in both directions? Is the reservoir full of oil? Hopefully it's something easy like bleeding, oil level, or linkage/belt, and not something internally. Free air speed vs. loaded and audible engine pulldown might give you an indication of linkage or internal leakage/hung port relief.

Does the repair kit come with the springs that caused the problem in the first place?

Hello, yes the cylinder block kit in the video, the one where I talked about checking to make sure they all move freely and don't have plastic wrap stuck in them, comes with everything (cylinder block, springs, and pistons).
