Is this a model a part Need bearings
Can You tell me if this is a model a Part. It comes out of the universal join housing to a coupler shaft and to the fire pump on our fire truck. I don't think it is on your standard model a but not sure. The needle bearing is bad and if you look at the picture the other end has a felt type seal held in by a washer and circle clip. I need to replace bearing and seal but the bearing has no numbers and im sure the seal doesn't either The tube housing measures 5" long tube od is 2 1/4" bell is 4" diameter. Measuring old bearing the best I can do to wear it is id 1.25 by od 1 7/8 length 1 3/4. Also notice the ball bearing in the hole in the housing Please give us advice on finding these parts Thanks

Re: Is this a model a part Need bearings
I am away from my shop until late this afternoon but the roller bearing sure looks to be a standard Model A driveshaft bearing. Is there a removable inner race in the tube that the roller bearing mates to? What is the od of the shaft that passes through the roller bearing?
I will update the size of a stock roller bearing when I get home unless someone beats me to it. Can't make out the ball bearing from the photos. Good Day! |

Re: Is this a model a part Need bearings
What appears to be a ball bearing is the raised tab that holds the spring loaded race in place push down and tap backwards it will slide out, I don't believe the race is available.
I just checked, the race is available, have them check the diameter as some AA parts are larger.

if the rollers seem loose I think you will find that even the new ones are like that. Bob |

Re: Is this a model a part Need bearings
I called snyders today they no long carry this bearing so they could measure it for me, Can you give me the dimension of the 2 front drive shaft bearings so I can look for the correct bearing.
