CNH Part#86590117, 400 watts. It's made in the USA(!) and also has LR1843 stamped on the body. The o-ring OD is 1.600" and the inside edge of the body is 1.588", measured with my old Mitutoyu calipers. I paid $34.30 out the door, which was cheaper than ordering online and paying shipping, plus it supports my local business.
Asymair, if yours is the same design: try a prybar at about 4 o'clock and/or 10 o'clock positions, after backing the bolt off about 5 turns. Don't go back too far or the little spreader bar will drop into the block. Pry the whole body away from the block at those positions and it MAY force the little wedges back enough to allow removal. I mention those positions because on mine the directions say to point the element at 7o'clock, and the wedges are at 3 and 9 with the element pointing to 6 and plug connections at 12. (hope that makes sense).
I forgot to look at the list of applications to see if the 1510 is included. I'll do that and let you know...
