Hope this help someone filling the oil.
This is what I've been using, add the pin to hold funnel.
I only had to add a small piece rubber hose at the tip, to extend reach (Walmart funnel).
Adding oil with that funnel will take for ever and spill all over the place. I just changed all fluids on my BX2200 and gave it a try and it did not work out. I used my big funnel and it went a lot smoother.
I use the same funnel to fill my tractor with fluids. It took a long time to feed 7 gallons of UTF through that thing in January. The hardest part of the whole 50 hour service was holding the 5 gallon jug up for that pour. I still use the funnel, beats the heck out of the alternative.
