Kubota L48 HST issue

[100 td]

D100jj4, what is the serial number of your tractor?

rbargeron, just noticed a difference in your parts diagram compared to the one on Messicks site. (I don't have access to USA kobota site parts diagrams)
Your diagram shows old parts, with a fitting added to the banjo bolt, so perhaps the steering fluid used to enter here, until it chewed out a heap of transmissions and Kubota worked out what a silly mistake they made?
I wonder if there was ever a recall or mod done to them?

Does your manual by chance have a schematic of the circuit?...........

Copy of the schematic attached - 2 pages

Schematic shows PS emptying into charge pump line to tank, perhaps before serial break when they half fixed the problem, (and it is a schematic, so tank and line may be indication only)but there is something in the line to the pump (strainer?).

.......there is something in the line to the pump (strainer?).

The little triangle at the tank end of the pipe is similar to graphic symbol ANSI Y32.10, 5.2 (strainer or filter).

I removed the suction strainer this morning and found no debris. Clean.
I didn't get a chance to check the clutch yet but if clutch us okay then I do have the capabilities and tools to separate tractor.
Im gonna cut open filter tomorrow and see what I find!!

Thank you guys for all the input. I will keep you posted!!

I know that symbol, I'm wondering what is in the line, can't tell from the photocopy, looks like a throttle valve or something else?

Great. Well really, it would have been nice for you if it was plugged!
As previously noted, hopefully the clutch slips like crazy!

On the original, those smudges are two parallel hash lines " l l ". Clearer ones are shown at the (20) filter.

Not at the boundary, go up a little on the line to the charge pump.

Perhaps a boundary mistake from cut/paste/mods from one drawing to another. Like their electrical schematics, they aren't perfect, I have found other Kubota schematics with check valves placed the wrong way around. Hopefully all a wasted exercise and D100jj4 finds a crook clutch!
