Anyone know a source other than Cl***ic that can retro speedos for use on a TH350? Got a '49 Buick speedo wanting to use, but can seem to find info on what ******s buicks used back then and if it cna be done w/o spending 1100 bucks with Cl***ic to have them do it......thanks in advance
it so happens we used a very early 50's Buick speedo on our T Bucket, with TH350. The El Camino cable we used hooked right up, by that time I think all GM Speedos used a standard thread on the rear of the housing I know it's not specific info, your mileage may vary!
i'm not sure what you are asking. if you want your gauges rebuilt/updated or changed to 12 volts..these guys are real good: http://www.gaugeguys.com/ if you just want to connect your buick speedo to your TH350 , the stock `49 buick cable may just go on..you could also find one that would work if you went to a real auto parts store and the parts guy knew what he was doing .or you could have a custom one made at a speedo shop or maybe you are just trying to know how to get the speedo to read correctly? ..all speedos are calibrated so that 1000 RPM's of the cable is 60 miles per hour. if you need to correct it , you do it with the the speedometer gears in ******
Yeah--ain't no conversion involved; virtually all older speedos need the same ratios of speed to rotation, 1,000 speedometer rpm=60 MPH... And there aren't very many different threads around for post 1930 or so speedos or drives. If you are unlucky enough to not be able to find a stock cable to fit (what you probably need is about any GM from before the clip-on speedo end cable of about 1968), the place I'll post will make up a cable with any ends or length faily cheaply. I'm linking their calibration page here... http://www.speedometershop.com/rep-pag.htm Here's my personal rant on what I do with elderly speedometers: Here's my speedo repair technique: remove bezel and gl***, get speedo out of case. Get a tin can or something that allows you to set the speedo down with face up and secure balance, and study how you are going to hold the thing so neither your fingers nor the liquids to be used can touch the face or odometer. That stuff is VERY delicate and easy to destroy. Near the cable end, on what amounts to the speedo's main bearing, is a tiny br*** plug. Get it out--I usually manage to extract them unhurt by threading a tiny machine screw into the cup--and extract the piece of felt within. I then repeatedly flood this lube well with first kroil then WD40 as it frees up, sometimes liquid wrench if I feel something thinner is needed. You want lots of fluid to go in there and then leak out the bottom to dissolve and wash out the petrified lubricant and crud. When the shaft will spin freely by finger twirl--you should be able to get 5-10MPH easily by finger--soak several times with carb cleaner and then brake cleaner to remove all those miracle solvents. When drained and dry, I fillerup with Marvel Mystery Oil, based on my scientific observation that the only real speedo tech I ever saw in action used something that sure looked like MMO. Stuff felt&cap back into hole, well soaked. Let drain, re***emble. The multiple screwdriver tip sets you can get at discount stores contain a Canadian Robertson tip (square) that fits early Ford speedos and allows you to motor them up. You can also do a very rough test based on the supposed RPM of your electric tool, based on the speedo's calibration of 1,000 RPM=60 MPH. Here's a ratio test page: 1. http://www.speedometershop.com/rep-pag.htm
Try United Speedometer in Fresno, Ca. - not sure of the address, but you should be able to get it off of the Net.Greg
