ZT 2200 EZT transaxle is the whole assembly
within is the center section as well as the motor block and pump block.
the blocks have pistons / springs and thrust washers.
Need the piston **** (brand new) SPRING LENGTH**** for either the pump or motor block. asssuming the springs are interchangeable for either block. Again,, this request is only for ***NEW*** springs.
So,, if anyone has a new puimp or motor block,, can you please measure with a caliper and reply? most calipers dont go to the 10'thousanth but if you calibrate and jot down teh spring length go ahead and estimate the 10 thousanth.
Bonus to anyone who can state the spring height at "x" value ft/lbs. example,, you tell me you set up a spring and applied 10 ft/lbs compressive force and the total spring length or better known as "spring height" is "X" value.
willing to pay for both answers.. jcassity AT frontier DOT com / 304 772 4082,, ask for scott
these two answers do not reside currently in:
-service manual
-Tech Support (states the info i want is proprietary
My purpose is to narrow down to the gnats ass what exactly is the failing part now.
what my issue *WAS*> zero turn mower equpped wtih 2) ZT-2200 transmissions , left trans became unresponsive after warm up,, repsonse gradually went away up to the point the mower was unsafe to operate. I took the left apart and using several grit stages of wet sanding ,, i cleaned the minor record player gooves prodominantly out of the *motor block* and very mnior ones on the pump block as well as the center section.
What my issue is *NOW* > left & right are both equal performers when cold,, Both transmissions equally loose about 10% after hot (which according to tech support this characteristic is expected with units having high hours. Therin afterwards,, the left unit continues to loose about 10% more response.
this means my left trans is at 80% when hot,, and my right is at 90% when hot.
link here to one of a few vids i am doing to *solve* this issue. its my belief that this particular facet of these motor/pump blocks have not been addressed yet by anyone. What i mean is there is "some" info on cleaning / facing the surfaces of the motor/pump block to center section,, yet if your problem is partly still there,, then the only items that remain are the springs becoming weak or becoming "shorter" by just a smidge. Once i know a "spring height" value,, i will reopen mine and if i am short,, this means i can * shim * behind the thrust washer on all springs to take up that difference. My thoughs are not only did i have center section surface damage but over use, i have also lost piston surface presures due to the springs themselves becoming more worn. Springs alone are not for sale according to tech support and this is telling in my honest opinion. there is nothing at all wrong with my wanting to troubleshoot this deep. if this is not your cup of tea, then keep it to yourself. There are still people who want to find out what all the probable faults are when doing a repair.
i did complement hydro-gear on their buisness modle. Us men have noticed these transaxles piled up at shops and to me,, the first time i saw that it was clear message to me that "i better not even think about opening those puppies up" or "those must be hard as heck to work on",,, when in reality they are not. What hydro-gear has done is perfected the balance of customer use vs customer repair ratio's. If a repair shop tries to repair,,, then the center section,, pump block, motor block , seal kit,, oil change and labor to do said repairs are cost prohibative because your now just a few more dollars away from buying a new one.
Also i am just facinated with the human mind that this hydro/mechanical unit performs such huge amounts of work and like magic,, they completely reinvented piston stroke and virtually eliminated "reciprocation" by keeping one block tipped at a 30 or so degree angle. just like the kiddy ride at the local state fair,, i think its called the "tea cup" ride,, that concept is applied within this magical performer.
