Great idea, I have done this on computer fans before. I got an insulin syringe from the pharmacist at wal-mart. The guy thought I was crazy at first when I asked him but I explained what it was for. I was actually surprised he gave me one. Just watch out for the trolls who have nothing better to do than scold people who open up a leased IRD which violates DTV TOS. I'm surprised they haven't shown up yet. I haven't had to do mine on my HR24 but it never hurts to lube them.
