Use a Shop Vac to Prevent Loosing Hydraulic Oil on a filter change! Kubota M owners must watch! - YouTube

gee whiz, don't tell everyone our secrets

actually works quite well on a lot of machines, I was shown this technique back in the mid 90's

couple of pro tips;

select an old vac you wouldn't miss if it were ruined for anything else. needs to be big enough to hold the whole compartment just in case, and healthy enough to carry on through the whole process and not poop out mid way

clean vac of ALL dirt inside and rig for wet operation. small amounts of fluid will be picked up and carried into the canister. make clean-up easy on yourself

don't position suction hose too close to fluid level. vac will pick up small droplets to full on stream of fluid without sufficient air gap. you may have to create small air bleed holes in the connection, too great of a seal will simply evactuate the compartment into the vac canister

utilize a helper to hold suction hose or fasten it really, really well. use your imagination to picture the scene when hose flops off while you're laying underneath with filter removed

have sufficient size drain pan positioned directly under filter or fitting being removed along with splash shield (cardboard is good for one-time use) and a few shop rags

have filter, fitting, etc. prepped for the swap including any gaskets, seals and tools needed

the gurgling is normal. don't be alarmed, it's supposed to sound like the end of a good milkshake

good luck!

these also work great for cooling system work like changing b/o fittings, filters, even block heaters

good ones have an air regulator or ball valve to adjust vacuum
