Bobcat 753 bucket Tilt cylinder head will not come off

My local hydraulic shop has been trying unsuccessfully for two days to get the Tilt cylinder head to come loose they have heeded it up three or four times but their head just doesn't want to come off! The Bobcat spanner wrench useless! Bobcat with all their infinite wisdom! made the cylinder head only about a quarter of an inch thick pretty much rendering a pipe wrench useless. there's just no meat for it to grab onto. Has anybody had this problem before if so please help?

Unless you went to the most useless hydraulic shop it the world, they should be able to get it apart or know when it is junk. The design of the cyclinder is very common and nothing special to bobcat. There isn't a lot of meat, but force comes to shove, I have gotten them off with my snap-on pipe wrench pliers. The aluminum head can really get seize into the the steel body good. If heating the body red doesn't get it to go, by the the time you do get it apart, the treads in the barrel are junk.

Bobcatdan is correct. Mine is off a 763 but identical to yours. We had to use a 10 foot cheater pipe connected to a pipe wrench and still took one hour to turn out that aluminum gland. It was toast as the pic shows. Were no treads left. It was all galled to the steel tube. Aluminum gland and steel tube... dis similar metals... just fused together. I say a very poor design for the neck of that gland. If you're lucky enough to get it out, you'll be buying a new gland. Was still cheaper than buying a new cylinder which was @ $1,000 (from Bobcat) Good luck to you.

I had one like this too, it took heat and an air chisel. Took me a few hours with my dad holding a pipe wrench on the gland and i bashed it with the air hammer. It would move it little by little.
When it was out, the gland was also dead, i had a lump of aluminium and machined a new gland.
