Scag tiger cub deck

[Finestlawn1]

I’m working on this Tiger cub that I picked up as a project. Any tips or tricks for getting the deck lift pivots to loosen up? The deck is stuck solid. I tried to put grease in but it was a no go. Can i use heat? Are there plastic or metal bushings in there or anything? I’m picking up a can of Kroil tomorrow to try soaking it for a while. Ive never had one stuck this bad. Any help is appreciated

Will the zerk take any grease or is it plugged?

Plugged, I’m going to swap them out and see if I can force any grease in there.

Hit the zerks with heat and a small nail and air compressor blow gun to unclog the fittings. Sometimes it works.

Zerks are clear but I can’t get grease to go in

Might try a Grease Fitting Cleaning Tool that inject solvent into the area. Note these do fail depending the solvent used so if needed replace the o-rings that are compatible.

I have seen these available but brought one yet as I am McMaster's some questions as I use Acetone.

After penetrating oil. could you 'tap' on the arm with a hammer to try to loosen it up?

The shaft looks like it is welded on so a nut or other arrangement must be on the other end. May have to disconnect the push rod and chain from the lever and hammer it out from the other end. Soak it good with penetrating oil and use heat. If there is a nut on the other end remove it and put a sacrificial nut on the end to preserve the threads while using the hammer. You may have to remove the deck to get to it. Last resort!!!! I once had to remove a broken bull sprocket from a Bucyrus Erie dragline. Soaked it with penetrating oil, set up a hydraulic puller, applied lots of heat and pumped the puller. It did take over 5000 lbs/sq inch before it popped. This was back in 1975 and the dragline was a 1942 model. When I called Bucyrus, the parts guy said "wait" I think there is a new sprocket back in the warehouse, been there for years. Anyway, I got a new sprocket and the repair was successful.
