Mark Kikta Posted June 21, 2020 Share Posted June 21, 2020 Yesterday I began taking my front suspension apart so I can clean, inspect and paint all parts before putting the fenders back on so I can safely drive the car a bit. I got all the moving parts off except the link from the steering box to the steering knuckle. I could not get the slotted nut loose yet from the end of the link to drop the link off the steering box arm. Also noticed a lot of rust and deterioration on the spring clips and nuts on the right side of the car. The left side looks fine so far(until I try to take them off and clean and paint them). There must have been a leak through the tarps sitting there for years because I had a lot of rust on the bottom of the right hood lower piece and on these spring clips where water ran down. By the looks of the big parts book, the spring clips are the same from 1918-23 6-cyl and 25-26 std. Does anyone have extras of these spring clips that you would like to get rid of? I think I may need at least 1 replacement(maybe 2). I should not have any issue cleaning up and putting new bolts on these spring clamps. Link to comment Share on other sites More sharing options...
Larry Schramm Posted June 21, 2020 Share Posted June 21, 2020 Mark, The first picture is of the shackel bolts. Heating up the nut and removing it should not be a problem. The bolts should be fine, just look at them closely after you have them off and cleaned up. As for the bolts for the spring clips, I might be able to help you. I need to know the exact diameter/size of the bolts and length. I have a large selection of old bolts that goes back to the 20's or earlier with square nuts & heads. I know the current trip that you are getting ready to do with your springs. I did that trip on my '08 last winter rebuilding the springs. After glass beading the spring leafs, and basic painting, I used Sta-lube Moly-Graph grease between the spring leaves.

Hubert_25-25 Posted June 21, 2020 Share Posted June 21, 2020 (edited) Mark, My 1925 Buick shop manual states "Do not put lubricant of any kind between the leaves. If the leaves are lubricated the ride qualities of the car will be spoiled and steering will be affected. Care should be exercised in drawing up the spring shackle bolts not to bind the spring ends in the shackles. Tight shackle bolts cause breakage of springs near end. All spring clips should be well tightened. Use a good fitting shackle wrench on these nuts. Loose spring clips cause breakage of the spring at the center." You can do something with the springs at any time. I would think about wire brushing, Ospho , then Por 15. The reason I mention Por 15 as that very few coatings can handle any flexing. POR 15 has a little give to it. This would let you clean it up, put some miles on the car, and then assess if you want to do anything different or are good with how they operate.

Bloo Posted June 22, 2020 Share Posted June 22, 2020 (edited) It is good that you have the manual right there. Some springs want lube, others not. It is technically better to use a plastic lining rather than graphite grease. As Spinneyhill always used to point out, graphite will set up galvanic corrosion. That is most likely why graphite is no longer used, however plastic may not be appropriate in all cases, for one thing liners might make the springs too thick for the hardware. I am still using graphite grease in my 1936 springs which have never been apart and still have zinc gaiters. One thing I would point out is that graphite grease you are likely to find today (grease with a little graphite in it) is not the same as the graphite grease of the prewar era used on leaf springs. That was more like graphite with a little grease in it. Penrite still makes something similar, but I haven't seen it anywhere else. In the 1936 Pontiac shop manual G.M. defined graphite grease (as used on leaf springs) this way: Quote Graphite Grease is No. 2-1/2cup grease to which has been added 40% to 50% graphite by weight. G.M. Number 4529m Edited June 22, 2020 by Bloo (see edit history) 1 Link to comment Share on other sites More sharing options...
Hubert_25-25 Posted June 22, 2020 Share Posted June 22, 2020 Mark, As Ben suggested, I am just going to kick the dirt around this one and provide a little data. Attached is taken from the 1926 Buick Standard and Master reference book (With the snubber picture). Also a page taken from the 1925 Buick General specification regarding Snubbers. Snubbers were found on the front only of I believe 1922 Buick (on up) long wheelbase models, as I bought the pair that was on Jerry Toews car. By 1925 they were still on the front of Buick's larger cars. All Buicks (at least in 1925) had the frame drilled for snubbers front and rear. I have driven a model A ford with no shock absorbers (as many were removed after they needed rebuilding) and then after installing rebuilt originals. Two completely different cars. They taught us in automotive class to push down on the front corner of the car and then let it come up. If it bounces more than once, a person needs new shocks. On these old cars with front leaf springs, it is very difficult to get them even moving. These leaf springs have a lot of friction preventing movement built in. My 1925 Buick Standard currently only has springs. I have not put any lubrication between the leaves. I can tell that I think the ride would be improved with shock absorbers, but Buick used Snubbers at the time. I have a set that I plan to rebuild and I can report one day how effective they are. Interesting that they would drill the holes for snubbers, and then not recommend installing them in the generals specs. I do not know if greasing a spring makes it act like a softer spring. I can only guess that it probably does to some degree. Was the earlier note about greasing springs in reference to models with snubbers? The snubbers do work differently than shocks in that they only slow movement in 1 direction. A shock slows motion in both directions. I think shocks were added to Standard cars in 1928, but those may be the lever action dampeners. I have seen front and rear snubbers on 1927 Standards. Not sure if they were standard. This is why my suggestion is to clean up what you have with a minimal amount of effort. Work on what really adds value to the car and enjoy it. Sweat the details on the smaller stuff for a later day. I am glad that you are so close to going for a drive. Hugh 2 Link to comment Share on other sites More sharing options...
Mark Kikta Posted June 22, 2020 Author Share Posted June 22, 2020 Hugh, You mentioned a shackle wrench ..... What is that? I don't think I have ever seen one. A wrench I don't have? Maybe I need to get one? Link to comment Share on other sites More sharing options...
Hubert_25-25 Posted June 22, 2020 Share Posted June 22, 2020 Mark, No clue what a good fitting shackle wrench is. Given what I have seen of vintage tools, it probably means anything but a plumbers wrench, which seemed to be the tool of choice. The other interesting comment is the last note regarding lubrication in the 1926 reference book. They are still on no lubrication, but added "In case of squeaks, there is no objection to oiling the clips and placing a small quantity of lubricant at the ends of the leaf springs." So maybe the intention is that you should have no grease where the springs are clamped together at the center. You definitely do not want them moving here. Then the majority of the spring provides some friction to accommodate dampening, then just a little lubrication on the tips where it could reduce some noise and prevent the greatest amount of wear.

Mark Kikta Posted June 23, 2020 Author Share Posted June 23, 2020 I took the axle and springs out tonight after work and the bolts were as rusted as I thought on the large Ubolts. After I get all of these parts blasted I can assess what I have better. Link to comment Share on other sites More sharing options...
Brian_Heil Posted June 23, 2020 Share Posted June 23, 2020 For what it’s worth, I was taught when I took an automotive chassis engineering course in college that leaves are not to be lubed. The reason being is you need the internal friction of leaf to leaf to provide dampening in both direction. Never lubed mine and I have no squeaks. Above it was asked about snubbers. They were not standard on any 1923. Can’t speak for other years. I'm just one data point. 1 Link to comment Share on other sites More sharing options...
Mark Kikta Posted June 23, 2020 Author Share Posted June 23, 2020 I have been soaking these bolts for 6 months with liquid wrench which really helped. My large impact wrench took them off like butter where there was enough nut to grab. Otherwise the old large chisel and hammer did the job. Only one U bolt had any threads rusted away. Not sure if I can make that one work or not. 1 Link to comment Share on other sites More sharing options...

Brian, As far as I know, only standard equipment on the very top of the line cars. The 128" frames of the likes of 7 passengers and Broughams and Sport models. You should have the holes in the frame. Perhaps they started this in 1924? One other thing that I wondered about was the effect that balloon tires had on their operation. Some snubber cans are marked Balloon.

Mark Kikta Posted June 30, 2020 Author Share Posted June 30, 2020 After getting my parts back from the blasters, I believe I do need one spring clip for my front suspension due to corrosion. I have provided a drawing of it below. By the looks of the big parts book, the spring clips are the same from 1918-23 6-cyl and 25-26 std. I also listed this is parts wanted section Hugh did you say you have one like this for sale? Link to comment Share on other sites More sharing options...

Mark Kikta Posted July 8, 2020 Author Share Posted July 8, 2020 As I clean everything up good, I am about ready to start putting things back together. Here is my drag link all cleaned, painted and ready to assemble. In the second photo you can see the end that attaches to the steering knuckle. There shown is the screw-in plug which is concave on one end, and both spacers for the ends of the spring with one being concave to go against the ball. In the third picture you can see the screw-in plug and both concave spacers to go on each side of the pitman arm ball. I plan to use a liberal amount of anti-sieze on the screw-in plugs so they are never so hard to remove again. Link to comment Share on other sites More sharing options...
Terry Wiegand Posted July 8, 2020 Share Posted July 8, 2020 Mark, In the one photo, the ground ball contact button is different than what I have with the 1916.

Mark Kikta Posted July 25, 2020 Author Share Posted July 25, 2020 Well today I finally finished getting my front suspension put back together. I’m quite happy with it. It seems to work very smoothly especially after I lubricated all fittings well. 6 Link to comment Share on other sites More sharing options...
Hubert_25-25 Posted July 25, 2020 Share Posted July 25, 2020 Mark, Looks really good. Did you grease between the leaves, just on the end of the leaves, paint them all individually, or paint as a stack? Hugh Link to comment Share on other sites More sharing options...
Mark Kikta Posted July 25, 2020 Author Share Posted July 25, 2020 I had them blasted and painted them as a stack. I checked to see that the leaves were all free and not rusted together. 2 Link to comment Share on other sites More sharing options...
