Hey Guys,
I’m having a hard time getting to the motor mounts that  attach to the frame, not the engine. Can someone share how they got them loose. What size is the nut?  3/4’’ ? It looks like the are adjustable, in a slotted hole. Mine are all the way down on the slot making it hard the get a socket on it. A deep well socket is too long and a short socket, the bolt bottoms out before it gets on the nut. I have even tried a swivel extension. At a loss now. Oh by the way the engine is out off the car.

thanks

I use a wrench and go from the bottom.

The Motor mount attaches to the frame via a 3/4"-20 hex nut, 3/4" split lock washer and a very thick flat washer that is about 1/4" thick and  1 1/2" wide as seen in the picture below. If you have the original flat and lock washer and nut on yours, there should not be a need for a deep socket. If missing washers and maybe using a jam nut you may need something a bit deeper socket but I don't remember ever  having to use one.  

So, with a large nut like this you want to use the larger 1/2" Drive ratchet, extension, U joint, and nut.  Even if you can find a 5/16" Drive 3/4" socket you want to leave it in the tool box.. and if using 5/16" tools that might be a reason your socket will not reach the nut as they are usually shorter than the 1/2" Drive sockets.

With that here is my process from probably the last 50 of 58 parts cars: Raise front or front corner of car a bit & turn steering wheel so front wheel is turned out to give easy access under the frame area where motor mount goes through.  I use a 1/2 Drive ratchet, 1 foot extension bar, U Joint, & 3/4" socket, attached in that order.  I'm sure you know the old trick of wrapping electrical tape around the U joint so it doesn't flop around. 

Again, I never remember having an issue with that large nut, once I figured out the right tools to use.  When I remove an engine I always disconnect the motor mount from the frame via that one large  nut, since after doing it so many times it is almost always about a 5 minute removal per side.

If you are missing the thick washer, or lock washer and even perhaps the nut I do have all the correct, original hardware cad plated as seen below. You an see more pictures and details by Clicking Here.

Spark Plug Heat Range

Posted by Patrick Westphal on July 7, 2023 at 10:00am 3 Comments

I found a diagram that illustrates the main factor in determining a spark plug heat range that I was trying to describe to you during the chapter get together.

Here it is:

 

The main factor is the length of the ceramic insulator from the middle of the spark plug to the tip (where the spark happens)  

The insulator…

Lower Front End Ball Joints

Posted by Logan Robb on May 11, 2023 at 9:04am 7 Comments

Good Morning all! 



I took the 64 into the shop to have some adjustments completed and in the process decided to have the lower ball joints replaced as was recommended the last time I had it in. I ordered the parts and came into the shop. They quoted me nearly $500 to replace those lower ball joints requiring nearly 4hrs of labor. Now this is a reputable shop and they know me by name here and they will continue to get my business. I am just questioning what on earth is…
