Model T Ford Forum: Forum 2015: Jones Speedometer Swivel Drive Joint Question
Top of pagePrevious messageNext messageBottom of page Link to this message  By Douglas Dachenbach on Sunday, August 02, 2015 - 09:51 am:

I came into the position of two old Jones swivel drive joints. They were a bit rusty and locked up but I figured a good cleaning and lubrication might reveal a good working swivel. After a lot of “Oil Eater” and more paper towels I had a swivel with very sharp gears and everything in working order.

When I re-assembled the swivel, the drive gear rod to the cable slides in and out about 1/8th of an inch. Just enough to cause a problem. The pinion shaft doesn't move and is quite solid. I searched in Russ Furstnow's book and found a picture of the joint which is almost the same. The picture on the left is from his book and both drive gears have an extended point that fits into a dimple in the oil cap. The photo on the left is of my swivel and neither gear has that extended point and both caps have a flat raised center. Both caps are identical. I took my second swivel apart very carefully to see what is in that space that isn't keeping the drive gear in place. It looks like old dried up grease. Almost like a dry disc of grease or something that is compacted and breaks into tiny chunks. Does anyone know what Jones put in under the oil cap to keep the gears in place? Jones 1912-16

Kim Dobbins is knowledgeable of these too.

Douglas,
Jones did nothing special to the swivel to keep the input gear from moving in and out, BUT, once the pinion gear, with the two washers and nut, is installed on the swivel, the movement stops and your swivel will work well. While the removable ends on the swivel housing state "oil", I use wheel bearing grease to lubricate the swivel gear. I hope this helps.

BTW, This swivel was never used on a Model T Ford.
