Removing seized shackle bolts?

Hello All,

Looking for recommendations. I purchased the MorRyde CRE3000 with wet bolt / shackle kit. Jacked the camper up and the axels up, pulled the wheels, and did not get past the first shackle bolt. I have an air impact and a battery impact and could not get it to brake lose. It just spun. It was getting dark so I just put the wheel back on. I do not have a torch, so is there any other way for me to get these off? We leave for a trip in a few days and I would really like to have this installed, however because we leave so soon I also don't want to get my self in a half finished project situation.

Thanks for any help you can offer!

I suggested several times on this forum to cut a figure 8 inside the bushing to allow the grease to distribute away from the grease hole. You can't get enough pressure to force it thru a tightly blocked hole. Expect more joints to stop flowing as the wear will cause a better match and more perfect blocking.
I am not sure how to cut a figure 8 inside the bushing... I did file a relief or chamfer around the grease exit to help the flow.


Use a Dremel with a ball burr. It doesn't need to be fancy and don't make it very deep as the bushings are thin. Also, don't run the groove completely to the end or the grease will take the easy path right out.

That is a GREAT idea!!! May never use it now as I have MORryde IS on my RV and Dexter TrokFlex on my Boat and Motorcycle trailers.

Have heard stories of bolts not drilled completely. Also bolt holes under pressure may not pass the grease through. Try unloading them first then probably need to remove for inspection.


This worked. Jacked it up enough to take some of the weight off and the remaining zerks took grease. Still had to play with the angle and pressure of the connection but it worked. Thanks again all

First remove Zerk and see if grease flows thru it.

As stated, I finished the project last weekend and thought I was 100% done but it turns out I am 99% and that last 1% is giving me fits. Installing the new equalizer and wet bolt kit ends up giving me 14 zerk fittings to grease total. 10 of them are no problem but 4 just will not take grease. They are brand new so it's not old grease. Used a small pin/nail to poke the dot and that did not help. Tried for a while yesterday and again today and all I get is a mess around the zerk. Any tricks to fix this without pulling the zerk or bolt?

Thanks!

Glad you got it handled. Grinder and slitting disk would have saved you a lot of stress and exhaustion.


Oh!! , but it's more fun with a cheater pipe ,and busted knuckles . :B


Inexperienced operator in close space that spinning wheel can do more than bust knuckles.


Heavy gloves, long sleeve jacket and eye protection along with a bit of practice to get the โ€œfeelโ€ of how the grinder reacts goes a long way.

Many times it is Justas easy to overtorque and snap the bolt. Harbor Freight tools are an excellent choice for these one off jobs.

I like to tie a plastic bag around and fill with jb80 and let it soak for a couple days.
