First off- I have done the search option here,and have found more than one option,or different pics of how biscuits are mounted. I hacked on a SBC mount for my HEMI,and before I make the frame mounts,I wanna get this right. Pics below are- the P***ENGER SIDE- which I would believe is the correct way. The DRIVERS SIDE I have seen in several posts =IE mounts. 3rd pic is both sides shown,and the mount. Which is it? And a special thanks to some guy named Norwell who helped with making me see the light!
Neither. Take number one and turn the bolt so it goes from the bottom to the top with the nut and small washer on top of the mount. Then put a cotter pin in the hole. Don Hard to see in this picture, but notice the nut is on top of the mount. I don't have all the parts in place on this picture, like the big round metal cup that goes right under the big rubber insulator. Your frame or lower mount will sandwich in between the metal cupped plate and the smaller rubber insulator. (As indicated with the red line) There is a reduced size to the lower insulator and that part goes up in the hole in the lower mount. Then put the bolt in from the bottom going upward and you will be home free. PS, Jeff Norwell is a trouble maker, you have to watch out for him.
Thanks Don- I figured the P*** side was correct from posts i've seen=majority..... But haven't seen the nut on top. My mount has a "bigger" hole in it for the shank of the bolt. The mount I fab from the frame will probably have the "smaller" hole.. Thanks for the info!
You're welcome, and I was wondering how you got that bolt down through the saddle mount because they are a shoulder bolt with a much fatter shoulder than the threads. That shoulder is just long enough to go through the bottom insulator and then it shrinks down to the final threaded size (3/8 bolt, I think). Did someone drill out the saddle mount before you got it, generally the hole in those is about 3/8 but slotted for adjustability. Don
Like Don said, it's supposed to look like this pic. http://www.speedwaymotors.com/1935-40-Bolt-In-Motor-Mount-Kit,52261.html
Don- You are correct. This was a SBC mount that I got with my roadster. Jeff sent me some shots of what "should be" and I modified. Worked out great. The mount itself,has just a tick above a 5/8ths hole in it,so nut will probably go on the bottom. I'm making that frame mount,so i'll be able to fit it accordingly. just wasn't sure about the rubber configuration. Seen too many set-ups to determine! Thanks for your imput!-Mike
That's an excellent picture 327-365 posted, better than the one I just shot out of an old motor manual I have at home. Don
The problem you are going to have if you run the bolt down from the top is that the part of the bolt that will go through the bottom insulator will be sloppy. It is designed to be a nice tight fit around that insulator and the shoulder extends up through the cup shaped plate. I think it would be better to do it the correct way, even if the hole in the top mount is a little oversized now. You figure, 5/8 is only 1/4 inch bigger than the 3/8 threads, which relates to 1/8 inch slop on each side of the bolt. Even the original Ford water pump holes, that these mounts were designed for, were not that exact and tightening the bolt down generally took care of limiting any movement. Or, make a thin spacer that is 5/8 OD and 3/8 ID, and the thickness of the top mount, and drop it in the hole to take up the slack. I bet your local Ace Hardware has some bushing that you can take a slice off of and make the correct spacer. Just a suggestion. Don
Well noted,and thanks! That's what shims/spacers are for! I know I have something that will take up the gap. if the factories did it like that,I won't question.
Hemi+Model A+ new build without stock frame= ***** is an understatement! Not so bad,just one step at a time........
I made the whole in the frame the stepped down size at the top of the small bushing. Bolt from the bottom with the big plate under the big rubber bushing. The machined step in the thru bolt lines up better this way. I took a cutoff wheel and made a straight cut across the top of the bolt to hold with a screwdriver instead of trying to hold it from the bottom to tighten. These are the mounts from Speedway.
