I did the 600 hours service on the Grand L3830. I elected to change the hydraulic fluid too (didn’t do it at the 400 hour service, it still looked reasonably clean, honey color, when drained). About $140 for a 5 gallon pail of Super UDT2.
Changed engine oil and filter (spec is 7.1 quarts, it took 6.6 quarts)
Changed transmission/HST fluid and both filters (spec is 11.4 gallons, 9.4 gallons came out, I put in 9.8 gallons, the dipstick suggests it’s a quart or two overfull).
Changed front axel oil (spec is 6.9 quarts, took 6.0 quarts, used UDT2, it had 6.1 quarts and was above the check hole level)
Changed fuel filter (tractor started without bleeding the fuel system, but I remembered after about a minute and bled it for 30 seconds, it didn’t make any difference, it ran well before, during and after).
Changed both inner and outer air filters. It’s been a while since the inner was replaced.
Adjusted front axel pivot, 22 mm (spec is loosen lock but, tighten to bottom and then back off 1/6 turn, it was about 3/8 turn loose of spec).
I believe it was just over $600 in supplies.
Interesting thing, after draining the main rear transmission drain (24 mm) and the left and right rear axel hubs (13 mm), I found the fourth drain point in front (10 mm Allen) had no oil to give. It was still painted shut from the factory, meaning the dealer didn’t crack that one when they changed it at 72 hours. I guess they knew it didn’t matter.
The transmission suction filter (right side) had a bit of debris on the magnet. I’m glad that wasn’t circulating in there forever. That filter had a couple dents, suggesting I need to be more mindful of what I run over. Pierce either filter and I suspect it becomes a bad day quickly.
Since I’m documenting this for the benefit of others, if a person wants to be able to capture all the transmission fluid in one container that fits under the tractor (not on a lift), Rubbermaid’s Roughneck 14 gallon totes will fit.
