Splitting 660D skidder

[Rjm74]

Hello. I need to pull a Timberjack(JD) skidder apart at articulating joint. Everything is free but my backhoe won't pull it apart. I have driveshaft out.
Do the axle shafts have to be removed also?

Not familiar with the machine but don't see how the axle shafts would have anything to do with it? Got a picture or two to help us out?

I've only ever split a 460, and towed a 460. I assume you've got 3 tab center pins ? If everything is removed, cylinders and centers, back shaft out, your fighting wear and gravity. Are you splitting it to do pins ? We split mine on a pretty level concrete floor, couple big floor Jack's and some cribbing, 2hr job, took longer to take the chains off.

Are you pulling the front away from the rear or the rear from the front?

Did you block up the front to prevent it from flopping to the side? If not, that adds alot of friction to the joints.

I only ever split my 540A once. be very careful with having both sides well supported. sometimes old bushings or rest of old bushings shift up or down and block the eye on the part which you need to pull away and makes them impossible to split , not sure if that explanation makes any sense to you. look into your pinhole and feel it with the fingers if any bushing slipped, or even start measuring thickness of eye plates.

i had a excavator bucket not come of once although the pin was removed, bushing shifted into the next piece. it's a pita to pull them back in position because no holding edge, i think we cut it out with a torch

I got it. I was angling the cab end up and down to try and compensate for the bent lower tab on rear section. When I pushed down on arch and pulled it popped right apart.
I'm splitting it to fix a broken off upper tab on the rear section, weld both steering clevis back on the rods and straighten the bent lower tab on rear
Thank you all though
