ive heard of folks doing it without a crane but i would not try it , alignment is too critical with getting guides and stops back in and with nothing to move boom that would be too difficult
anyways: suspend boom end with double straps from crane , disconnect hydraulic/electric swivels/plugs at truck end lift end of boom slightly with boom all the way extended straight out , remove acess panel (both sides) at jct of upper/lower boom section . remove C clip one side drive out pin oppisite side (wiggle boom to clear pin) locate stops in lower section boom end unbolt , slowly pull upper boom with crane away take care of hydraulic lines and electric wires set on floor on wood cribbing , locate bottom of cylinder truck end find C clip and pin Might be behind a trim cover that might need to be remove drive out pin also remove bottom cylinder hyd hose connect crane to cylinder end move out a foot or so remove top cyliinder hydraulic hose then carefully slide out cylinider with crane , Note if your valves are not tight and new oil will leak back and cause boom base to sag when you unhook hydraulic hoses , your gonna need to block this up with wood cribbing just in case
reverse removal process to install new one , also i would not just install a new seal (you can) with out having cylinder recromed I'll bet it's rusty thats what tears the seals up
and allways replace entire oil volume in hydraulics your old seal is in old oil not good for the new one
I think you will find they are swivel joints top and bottom,if it is king-pins a press,reamers and a very striaght eye..will be required.Either way the front hub assemblies will need to be stripped down..Good-luck....
Start off by putting a cardboard box over the windshield and under the wiper arm to avoid breaking or scratching the windshield.You need to turn on the wiper switch and then turn on the key. When your wiper arm is pointing to the top of the windshield turn off the key to keep it there. Now, depending on the type of wiper arm you have ( bayonet, shepherd hook, L pin or straight arm ) depends on how to remove old arm. Shepherd hook is the most common and has a lock on the blade that needs to be pressed in to release the blade from the arm. Now slide the blade toward the windshield, off of the cradle for the arm. Swivel the cradle so you can slip the blade off from the inside of the arm and reverse procedure to install. The Bayonet, L pin and straight arm styles usually require a small flat blade screwdriver pushed between the body of the blade and the arm, then twist to release blade. Some blades also have a lock that will need to be pressed to release blade from arm, then twist screwdriver to remove. Hope this helps!!
hi from uk re wiper blade you only have to swivel blade enough to access the press clip that holds the swivel mount of the blade then while pressing clip pull wiper blade down out of the wiper arm U type hook replacement is in reverse make sure you note the old blade fits so you fit new one same way ?
