How many springs go on the rear end of a 25 TT ? I have two frames , one has 8 and one has 9 ( per side ) is there a standard ? I accidentally asked this question in the classifieds , thanks bob for pointing that out
I am guessing you mean, how many leaves in the spring set ???
Yep , been a long day , posted in classifieds first , then posted here wrong !! I'm goin to bed !! Lol !!
I count 8 in my early 26 TT. Too lazy to go count them on the 25.
My '18 likewise has 8 leaves on each side. I bet if you look carefully at the 9 leaf spring pack you have one leaf will be identical to another. One of the identical two is undoubtedly an extra someone added for some reason.
It's been several years since I built my TT chassis, but the way the springs are mounted in the crossmember, there is no way an extra leaf could be added. I don't know now how many leaves it has, but it was a bit hard to get the NOS leaves I found squeezed in there. I had to rig up a spreader to open up the mount a bit so I could get them in. Maybe there was a different number of leaves in the earlier TT's vs. the later ones, I don't know. Never ran into that or heard of it either, but for sure doesn't mean they weren't made that way. Interesting question. Maybe we're learning something else new! Rich Chillingworth, have you run into this? Dave
8 leaves in my 18 and 23 TT'S
3 leaves above above the clip
The top TT rear spring leaf is rather short and easy to miss if you're counting the leaves while they're installed in the frame. The Ford parts book lists 9 leaves as does the picture of the spring assembly. I'm pretty sure all years used the same spring count. As Dave Stroud pointed out, they fit snuggly in a clip riveted inside the rear cross member. The trick to installing the springs is to insert the bottom leaf last. It's beveled along the edge that slides into the clip, kind of like a chisel. Thus it spreads the clip open as you push it in.
Sure enough, Rich is correct. I just took a flashlight out to the truck so I could see all the way up into the cross member. There are 9. That top one is hard to see.
It's been 10-12 years since I had it apart. My memory isn't good enough to remember such a detail.....
Note that it is very possible that you do have a truck with 8 on each side. The top leaf (the smallest one) was prone to break. On my truck one was broken and the other was missing altogether.
I had to do something of a contortionist's exercise to feel up in the crossmember,
as the truck is a little buried while I do some other work in the shop. Guess I did
not feel up in there far enough to catch the little dude on top !
Henry is exactly right about that top leaf often being broken. The chalk line on #2 shows where the missing part of #1 should be. When you see the old photos of these trucks grossly overloaded, this is not a surprise.
Yes it is 9 leaves. Here is a pic of the whole family:
Actually, it has eighteen leaves.
Thanks guys , all your help sure makes things easier , the frame that we removed the rear end from was really bad and there were many missing springs , when. counting the ones we had we got 8 and 9 on our other frames , assuming 9 on both now , we have a stack of springs and now thanks to you guys we now know that we have a complete set to put under the 25 . Thanks again , and maybe someday I'll be able to have " the answers " to somebody else's questions , thanks again !!
All we ask is that you tease us with photos as you move along with the project.
Front springs rebuilt and in , tears awaiting placement , hopefully later today
