1. So I've been doing winter maintenance on my tractors & equipment as I'm sure many of you are.
Monday was the dreaded 60L of Kubota Super UDT2 transmission fluid and 3 $35 filters.
Got it all changed OK.
I give all my used oil to my buddy who uses it to heat his shop.
When I came in with the fluid, he asked me what it came from. I told him it was used hydraulic fluid. He said "good, I'll use it in my old case backhoe since its old and leaks fluid".
Couple days go by and I stopped in again to bring some engine oil. He told me that when he went to use my hydraulic fluid, he noticed a decent amount of fine metal flake in the oil. No chunky monkeys, just paint speckle size particles.
Another thing that bothered me: Owners manual says Kubota hyd filters are supposed to have magnets. When I removed filters from previous hyd oil change, there were no magnets. New filters did not come with magnets, either. Called dealer, he says "don't worry about it, oil drain plug has magnet and that should take care of it". I did notice a strong magnet on plug and it did have particles on it. However, it bothered me that no magnets on filters and metal flakes were in oil.
Tractor only has 610hrs on it. It had previously been changed at 125 hrs. So roughly 500 hrs on fluid. Change interval is 600 hours, so I'm under the change interval
Question is: should I worry?
2: on my M9540, owners manual says change interval on transmission oil is 600 hours, but it says change trans filters every 300 hours. If I remove trans filters, I would estimate well over 1/2 the fluid will drain out. In fact, I began to remove one filter and about a gallon drained out. I screwed filter back on and decided to pause.
My question is: Is Kubota expecting me to change filters at 300 hr interval, saving the fluid, then adding the used fluid back into the tractor?
Or am I not understanding something?
