The
L48's (and other similar Kubota tractor's) maintenance
schedule calls for hydraulic+HST filter changes at 200HR
intervals but hydraulic+HST fluid changes each 400HRs.
So I'm curious how folks have chosen to carefully drain the
10-14 gallons of UDT without unduly contaminating the fluid
in the process.
The obvious first which comes to mind would be to clean off
the drain plugs before cracking them open. But having all
14G of fluid spill into a wide, open trough would seem to
invite falling/air-borne crud making its way into the
business.
Some thoughts I had were to pump the bulk of the fluid out
of the tractor via a small pump pulling it from the dip
stick pipe, and drain the (presumably small) remainder via
drain plugs. This also sounds more manageable compared with
wrestling 14G of oil out from under the (now immobile)
tractor.
Alternatively it could all just dump from the drain plugs in
to a trough, and pump-filter the oil before it was headed
back into the tractor. Actually pump+filter sounds like a
good idea to get UDT into the tractor in any case.
Any experience welcome.
