I was able to get it off finally, you are correct, about half a quart of dirty oil in that lobe of the oil pan. Thank you for your reply.
For the Record on the ISEKI TS1910 or the BOLENS G-194 Tractor:
Rear Lift Hydraulic Fluid: Lucas Oil universal hydraulic fluid
Transmission and Front Axle: Lucas Oil/Heavy duty gear oil SAE 80W-90
Engine Oil 10W40 Diesel {Shell Rottella Non-Synthetic}
Fuel Filter = WIX 33262
Oil Filter = WIX 1568, or FRAM PH8A, or STP S3600
Air Filter = {Unknown}
If anyone knows the WIX Air Filter part # please reply with it .... I am looking for it, please reply with any corrections or improved products for the ISEKI TS1910 or the BOLENS G-194 Tractors, or any products that will cross over and work well on this little Tractor.
Thanks,
Dan
