We have purchased an ole NH LX 885. Had a 865 glad to be back in business with this ole gal. Bought as a fixer as previous owner ran over something hydraulic pump leaking. We have it almost out but the two parts that appears to be holding us up can't get them to let go tried a 3 way puller can't get enough bite. So it's a small control arm x 2 Question is any tricks or any snap ring we are unaware of. Sorry for poor explanation will try to find a parts breakdown and give a better explanation. This is for main hyd pump underwear. TIA.
