Read articles →This is a hands-on, real-time DIY walkthrough of swapping both the hydraulic filter and hydrostatic transmission filter on an L3902, including part numbers, dealing with a factory-painted filter stuck tight, refilling with UDT2 fluid by the quart while checking the dipstick, and a final startup/leak check. It's practical and detailed but filter-focused only, not a full fluid drain, useful for owners planning this specific service themselves.
Posted by the Garming channel, an owner doing their own maintenance rather than a dealer or professional mechanic.
The filter is painted at the factory which acts like glue. Score under the seal with a utility knife, then use a filter wrench with two hands, and tap around the rim to crack the paint seal.
Kubota UDT2 Super Trans hydraulic fluid. The video used about three quarts total after changing both the hydraulic filter and the transmission filter.
The transmission filter is on the left side of the tractor, is yellowish colored, and does not have a magnet like the hydraulic filter does.
The video states it is about every 400 hours for the next filter, oil, and fluid change.
