rebuilding a speedometer
I was wondering if anyone knows of instructions on how to rebuild a speedometer, I got most of it apart but ran in difficulty getting round magnet at top and gear at bottom apart...the only thing wrong with it is the old grease makes it drag too much..I did finaly get enough of new lube inside so that it spins freely but would have liked to totally take it apart..just dumb enough to try...

Re: rebuilding a speedometer
I have had great success by drilling a 1/8th hole through the thread where the screw holds the case to the innards at the back through the pot metal until you just hit the centre drive shaft..and pour some lube in .
I was not game to try and pull them right apart, so salvaged a couple of old almost impossible to turn speedos. I cleaned all the congealed grease from the bottom bevel gears, but they would still hardly turn. Both speedos have been running fine in rods for 2 to 3 years now and they run much faster than a stockie, so I declare this bodge job (modification ) successful. |

Re: rebuilding a speedometer
Here is a link to an article Written by Gordon Fischer.
MODEL A FORD SPEEDOMETERS The following material covers the disassembly, cleaning, repairing, installing decals, lubrication, calibration, and assembly of the familiar oval speedometers manufactured by Stewart Warner. Oval speedometers were also produced by Waltham and Northeast Appliance Corp. Northeast produced an oval unit without a trip indicator, and with a speed indication from 0 to 80 MPH. Hopefully these instructions will be of some use if you have a Waltham or Northeast Appliance unit. Refer to MAFCA judging Standards for questions of authenticity, such as style of numbers, thickness of the rim of the bezel, trip indicator, red and white pointers, etc. http://www.modelahouse.com/tech/spee...r/fischer.html Handouts courtesy of THE BEAVER CHAPTER, MAFCA Portland, Oregon.

Re: rebuilding a speedometer
Wow, thanks 160 B...as for Carl G...you left out the most important part..sending in the payment...if I hired all things done to restore a model A..I would have to be wealthy... which I am not..besides the hobby to me is about getting things done yourself...and the satisfaction in doing them...and saving stuff most people throw away..

There is a tremendous amount of truth in that. While not everyone is able (due to constraints/obligations/etc) to do things like this, I honestly wish there were more with your attitude in this regard. I think what happens to many folks, is they are under pressure to have a task completed quickly and correctly. If more folks took the attitude to slow down and learn by physically trying/doing, the mechanical aptitude of this Country would increase several hundred percent, ....which is exactly what our economy needs! |

And, of course, with everything comes a cost. It's really a matter of what I feel like I can do successfully , and what I feel is better left to the professionals. Most often, the cost for a professional to do the job right the first time is actually cost effective when you consider the cost of the parts and then having to do it several times over and still not getting it right.

Re: rebuilding a speedometer
I had some good pictures of how far I take a speedometer apart to lube the gears and bearings. I have never removed the bevel gears, nor the speed wheel and shaft. If that needed to be done I'd sent it to the experts with the right tools.
Here's a link to some speedometer repair and my reply to what I have done. The next one I do for myself I will have to take new pictures. http://www.fordbarn.com/forum/showth...+tom+wesenberg |

Re: rebuilding a speedometer
Hard lube in the speedometer magnet drive gears and shaft is part of the problem, The pot metal frame expands with age, causing it to squeeze on the shaft. There is also old grease in the odometer assy which causes them to turn hard. When you get to the next 1000 or 10,000 mile it has to turn 4 or 5 rows of numbers that have not moved in a while. It is a good idea to do some preventive maintenance on the unit before the hard turning causes a failure of the cable or one of the drive gears. My yardstick is to grasp the input with the tips of my fingers and try to spin it, if it feels tight, it is too tight, it should spin easily. As long as you have it apart, clean the lens and the faceplate, be careful with the numbers as they are very brittle.
