wonderful video! thank you! i am taking delivery on a new ZT1 50 this week and will be doing 100 hour fluid changes on the ezt-2200 hydros. i will remove and add a drain port / plug kit between the first and second bottom bolts (from front) on the inner cover. i just need to confirm no interference with the internals. why a manufacturer is even allowed to sell a piece of equipment full of oil without a drain plug should be frigg'in illegal. kinda goes to 'right to repair' thinking. thank you for your video. it is very helpful.
more to come,, watch all the parts.... there is one element to these trans units that bugged me and i am fixing that also. if you are about to open one up or have,, dont close it up till you call me at 304 772 4082. those springs on each piston will be the topic.
@@ifixitall-24-7 thank you! i will certainly keep this in mind. probably all i will do is pop the outside covers, add the drain kits to the bottoms, clean up the aluminum shavings and the bead areas, RTV the mating surfaces and close. as far as the springs, about the only thing i've heard to do is to just run really good 20w-50 (like amsoil hydro oil) in the units and change it out every 100 hours or so. i live in FL, so i mow between 65 to 75 times per year.
a new spring is 1.990' long. i joined a few message boards about mowers and many people are saying these springs in thier "used" condition are at .045 inches shorter. the springs are getting WEAK !!! up there is a so called thrust washer between thespring and piston. my idea is to shim the thrust washers tomake up the difference in spring height. SURFACE TENSION is critical on these center sections. My repair brought back my trans to about 85% along with new 20/50 oil. This is result caused me to seek out where the remaining 15% hides. its my belief the springs are the only remaining common denominator. I am doing this i just need to "do" and record it for the channel. I assure you **NO** one has looked at this yet. If you call tech support they will tell you they cant state the spring lenght because its a patent secret.
