720 loader information needed

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I have a loader for the allis 720. It's not the ark model but the original version. If anyone has one I would really appreciate some information. I need the retracted, extended, and stroke dim. and didn't write down the dim. I replaced the original ones with Magister cylinders which was the biggest mistake. BEWARE magister cylinder rods are mild steel. After 4 hours and 400.00 bucks later the rods for the tilt bent! I know these cylinders weren't the exact dim. as the original but were within about 1/2" difference. The lift works but because of the rod material I can expect to replace them later down the road. Any help would be thankful. Thank you and God bless.

	Pictures would say 1000 words. When you say you have the original version, depending on what brochure you happen to be looking at, you are referring to the Ark 600, 700 or Danco SV40 or SV41. In addition to that, there was also a Brantly variant & quite possibly a Johnson. Allis Chalmers put their name across the front bolster of the Ark models, but didn't manufacture them.
