#70001-00872 SEAL KIT

(1 hour)
Disconnect and remove hydraulic cylinder after removing plow from subframe and depressurizing lines. Remove hydraulic lines from cylinder (have an oil drain receptacle available) - move piston in and out to drain oil from cylinder. Use gland nut wrench to remove gland nut, remove piston, disassemble piston ends, change seals and reassemble. Good videos on you Tube - most hydraulic cylinders are very similar. Did have to make custom pins for gland nut wrench - just filed down some bolts to use as pins in the gland nut wrench, worked great!

My cylinder was older and used a o-ring and an orange rigid ring on the inside of the piston. This kit replaces it with a blue cup seal. The key is to ensure that the cup side of the seal is facing the pressure side (base) of the cylinder. This tool is great for taking the cap off (may have to size the pins to the correct diameter). https://www.amazon.com/dp/B08LH1JJ23?psc=1&ref=ppx_yo2ov_dt_b_product_details This tool on Amazon makes installing the inner cup seal easy. https://www.amazon.com/dp/B0B58YPZH1?ref=ppx_yo2ov_dt_b_product_details&th=1 These Youtube videos will help. https://www.youtube.com/watch?v=3oz2JgT5T1A https://www.youtube.com/watch?v=vdfwTVNtJcU&t=630s
