Damaged Bolt on Top of Motor Mount

[hazeldz]

The passenger motor mount was a breeze to install on my 1980 300TD; I didn't even have to take the air cleaner housing off. When I reached the driver's side, I was unable to secure the upper inboard mount bolt in any way. My phone's camera is completely ruined because I jammed it in there. Is anyone familiar with this scenario?

I attempted to temporarily use the old driver side while retaining the new passenger side, but the lower bolt no longer lines up on the driver side.

I thought about attempting to take the arm off for easier access, but I also can't get it off. I was hoping that with the help of EZ Grip or something similar, I could gain enough traction to remove the bolt. I am about to receive new bolts. Getting the arm off and then getting in there to extract it seems like the usual procedure, but I've never used an extractor before.

There may be enough space for a rounded bolt extractor to reach the motor mount bolt, but I can't be sure. According to some, though, they are compatible with allen head bolts. If the engine mount has rubber legs, you may need to remove them before it fits.

Those are some excellent suggestions; I appreciate it. I have some torx on hand, so I'll give it a go and let you know how it goes.

Their offerings include long torx tools.

It is possible to drill the bolt head to its very core using a long drill bit that has an outside diameter that is greater than the bolt head. The use of a gentle 1/2-inch chucked drill motor would improve that.

Apply heat using a propane torch to the top of the aluminum arm, where the bolt is inserted. Because of the expansion of the aluminum, turning the bolt will be easier.
