So I am replacing (or attempting) to replace the motor mounts so my engine vibrates less (or that is the hope). I got top and bottom bolts off of the left side, but only the top off of the right side. Note those are mount bolts themselves, not the brackets to chassis or motor. The port in the chassis on the RH to get to the bolt is not big enough for a socket and no chance of a wrench. But it does have a bracket with two bolts so I removed those and so I started to jack up the engine via the sump and some lumber. But what I find is the entire chassis lifts...as if the mounts are still bolted on. I get a little movement, but vey, very little on the mount. I think it is more the right side than the left (keeping in mind my 73 is a left hand drive). The left hand side just has a simply structure. The right has a middle bracket that is between the chassis and motor mount. I am able to move the bracket on top of the chassis with a screw drive and some force, so as best I can tell it is not welded. What am I missing? Is it just 40+ years of self welding rust that is not breaking free? Potentially the threads of the bolt hooking on the motor side bracket? I tried breaking it loose a bit with a hammer, but really hard to get it in the vicinity to start with.
My only other option now is to remove the bolts out of the side of the block...and take out the entire assembly and deal with it that way. But since that is on the horizontal plane, the need to have the motor "hovering" so that the chassis or motor does not want to shift up or down as the bolt is extracted. Not excited about that. I was reading and researching...and I even saw someone post that the bracket on the right side may be welded to the chassis. For now, I soaked it in WD40 overnight and will tinker with it tomorrow.
I am also thinking that removing the battery, battery box, and other components in the area so that I can get a top down vantage point...not much space to work with from the bottom.
