Removing 755 Backhoe

I've decide to remove the hoe (for hose repair)from the 740 loader on the 69' 4500. I doubt if it has ever been removed before.

Since the crowder line has burst, the boom is vertical at this moment.

I remove the nuts that hold the tie bar links and using the stabilizers and lift nudged it up a bit. but the tie bar links really don't want to come loose.

Any tips, to get this done without problems?

Also the manual says to sit it on "jack stands". I'm assuming these are not the ones sold at Harbor Freight. Can railroad ties or concrete blocks be used?
 
I'm not sure how you would do it with the hoe up. Seems like there would be a lot of tension on the hooks. If they do come loose there should be nothing to stop it from crashing down.
 
Sounds to me like it's in a bind.You say the dipper is vertical.Try to curl the bucket to square everthing to the frame.If it does loosen up lower the stabilizer bars and raise it up.To get it high enough to clear you may have to put blocks under the stabalizer pads.We used wood blocks to set em down on.Good Luck.
 
I would put hose back on crowd , then use dipstick and stabs to free up hooks. Then lift with stabs and pull foward.Will have to connect 2 hoses together and plug other.
 
Best to remember that [b:d090af3665]it is always possible to kill yourself playing with tractors.[/b:d090af3665] Boom vertical sounds dangerous as heck. To pick the hoe off, you need three-point stability from the hoe - that's the bucket on the ground plus the two stabilizers, with the bucket far enough out to have the dipper vertical, or further away from the tractor at the bottom than it is at the top. In closer than that is a bad park position.

Without repairing the line,you may need to winch the bucket out if you can't creep it using curl and boom lift (uncurl with the boom up, set the boom down to get the edge in the dirt, curl to pull the dipper out, up boom and uncurl (block if need be to keep it from swinging back), take another bite. Or set the edge in the dirt and creep the tractor forward (stabilizers up) to get the dipper out (lowering the boom as needed.)

Dump some ATF (or ATF+acetone) on the top clamps, and tap them with a hammer. If you don't have heavy jackstands, timber works - just be sure it's stable (cribbed properly.) If you use concrete blocks, don't set them sideways (if you can see holes, they can collapse - that's not the strong way - set them like you were building a wall, or get the ones with no holes for this job.)
 
My bad - too tired.

It's the dipstick, not the boom, that is in the vertical position.

The hoe removed pretty easy, once the top links were wiggled loose. Should be a 10 min job, next time.

Resting comfortably on 3 points plus concrete blocks. The dipstick is chained into position.

Now, to the hose(s).

Thanks everyone.
