Wolf, thanks for the continued imput on this thread! I see you're super active, and answer (or at least point people in the right direction) on most threads on this forum.
We've isolated the GST pressure from the reducing pressure, with a special banjo fitting that he built. As soon as the engine is started, 360PSI were present instantly at the reducing valve. As such, pressure was being lost somewhere within the GST.
After all of the pressure tests we've done thusfar, we anticipated that would be the circlip would be the likely culprit. My father contacted Kubota via EMAIL, and requested a copy of the TSB about the broken circlips on the clutch packs. They referred him to the N.E. Division Rep. One week after his request, he received a phone call from a rep that told him that the TSB is proprietary to Kubto and he cannot be e-mailed a copy. He recommended we we check the rotary valve, otherwise go visit our local dealer in Orange, CT.
Based on this, he decided to pull the valve body on the GST. I think the pics speak for themselves...
We called the dealer, and they said we COULD NOT purchase the ENTIRE CLUTCH PACK ASSY. and that we would have to purchase the parts within it individually.... which means I've got to split the tractor again to identify which specific parts need to be replaced.
So my question: After I split the tractor again, do I have to remove only the CLUTCH HOUSING CASE to have access to the GST clutch assembly, or do I have to remove the MID CASE as well?
From other threads I've read to try and diagnose this issue, I thought that Kubot had release a "new and improved" clutch pack assembly for the L2900DT-GST (serial# 52797)
Can anybody point me towards somewhere where I might find the entire clutch pack assembly? It seems like when these circlips go, they damage the groove within the aluminum housing. If that's the case, I'd rather replace the entire unit...
Based on my parts manual from the Kubota website, my
GST clutch assembly should be TA040-61500.
But also in the book, from serial#54589 and UP, the clutch assembly part number changes to TA040-61502. Is this an UPGRADED design?
The dealer said this newer assembly would not fit in my particular tractor, and I'd have to buy the individual parts to fix this. Why are there two different assembly numbers for the different serial numbers within this model number tractor? Is the dealer just trying to "cover its ass" and sticking strictly to the parts book?
On Merrick's website, the TA040-61502 is listed as a REPLACEMENT for my 'older' TA040-61500.
Again, I would much rather buy the whole assembly and have the piece of mind knowing everything has been replaced.
Golden Eagle, Coleman Equipment, and Messik? Would those guys have any input? Would they carry the entire assembly?
