Int'l IHC 2000 vs 2001 Loader

What is the difference between the Int'l 2000 and 2001 loader? Is one any heavier built? I've seen both 2000 and 2001 with and without full hydraulics -didn't look added. Is this original on both? I know they can be ordered with different frames for different tractors. Mostly want to know if one is heavier built.
Thanks

The 2000 was designed more for the industrial market, 2001 for farming. I wouldn't interpret that as meaning the 2000 was heavier, just set up with different equipment. The 2000 came with hydraulic bucket. The 2001 came with a trip bucket and hydraulic bucket was an option. The 2000 was usually equipped with a wider bucket. They fit the same tractor models.

I have both. Subframes are the same. Lift arms are the same until you reach a point about 18 inches in front of the lift cylinder pivot point. 2000 had double acting lift cylinders. 2001 could have had double( same as 2000 )or single acting cylinder ( lesser lift capacity, gravity down ). 2000 had two dump cylinders on material bucket(60 inch or wider), manure fork (60 inch), or other attachments. Grease-able pivot pins on bucket, etc. 2001 could have had trip latch gravity dump bucket or fork or one hyd. cylinder for dump. Bucket or fork was 40 inches and fit between the lift arms on dry, non-grease-able pivot pins. Every 2001 that has a hyd. dump cylinder that I have seen in person (including mine)or in photos had damage and welding repairs made to the cross member connecting left and right lift arms. This damage was caused by the dealer ship, who assembled the loader for the buyer, not properly mounting the trunnion where the dump cylinder attaches to the above mentioned cross member. They neglected to drill two holes in the lift arms and install bolts as the setting up instructions directed.I can send you brochure scans with specifications if you like.

A copy would be great!
I have a 2001 with oneway lift cylinders and a trip bucket and another just like it unmarked (doesn't say 2001 or 2000) with a single cylinder on the center of the bucket and two way lift cylinders.
I thought the oneway cylinders looked heavier with 2" ram shafts, where the two way cylinders have 1 1/2" ram shafts. Cylinder casings on the two way cylinders look lighter built also. Thought I might be able to lift more weight with the beefer looking ram cylinders.
Thanks,
