littlemo Posted October 24, 2011 Report Posted October 24, 2011 Today I took out my front wheel bearings from the hubs I had removed from my 48 Ply sedan in order to "mike" the inner and outer races. I noticed that mine were of the "tapered-roller" type bearings. My "NAPA Guy" informed me these were incorrect bearings for the front hubs on a 48 Mopar??? Anyone know what type of bearings were typically used in the front hubs of 46-48 P-15's and when they were changed to the "tapered roller" type bearings ?? Thanks; Cass, alias littlemo... Quote
Don Coatney Posted October 24, 2011 Report Posted October 24, 2011 Your NAPA guy should go back to flippin burgers. P-15's have always had tapered roller front wheel bearings to the best of my knowledge. If you look closely the bearing numbers should be stamped on your old bearings. Also these bearings are almost bullet proof as long as they have clean grease and the dust caps are in place. Do you think you need to replace them? Quote

Your NAPA guy doesn't know much. They are tapered roller bearings on my '38 Chyrsler let alone my '48 Dodge and '53 Plymouth. They are a standard Timken number and I got them off the shelf from my local bearing place. Take your business somewhere else. ...........Looks like Don beat me too it but our info is basically the same. Edited October 24, 2011 by RobertKB Add information Quote
TodFitch Posted October 24, 2011 Report Posted October 24, 2011 Late to the party on this one. Near as I can tell from the parts books and from personal experience, Plymouth used Timken tapered roller bearings on the front wheels from at least the late 1920s through at least the early 1960s. I think that Chevrolet used ball bearings for a lot of those years but am not sure. For Plymouth front wheel bearings see http://www.ply33.com/Parts/group22#22-06-01 Quote
Plymouthy Adams Posted October 24, 2011 Report Posted October 24, 2011 sign of the times where front wheel drive cars are the norm and sealed double roller annual bearings are common place.. your bearing cage should have the proper number stamped onto them as with the race having its own number..worse comes to worse you can remove the races adn get the proper number there also..you did not mention what he stated where proper for you application..did he say?

RobertKB Posted October 24, 2011 Report Posted October 24, 2011 Should have mentioned in my first post but I strongly recommend if you are getting new bearings to get new races as well. They tend to wear as a unit. The races are not that hard to get out of the drum and replace. I take the old race and run the side of it on my bench grinder to make the diameter a fraction smaller and then gently tap in the new ones with the old race. Keep the ground down races for later or other projects as they always come in handy. I have several different sized ones I have done this to. Quote
Plymouthy Adams Posted October 24, 2011 Report Posted October 24, 2011 I was always taught from my first days as a youngster that they were to be replaced is sets..I still practice that theory today..only time I did not do that was as a by the road emergency repair where I scarfed a bearing from a donor truck to get me home...just grabbed the roller cage..replaced all new next day..got me the 200+ miles I need to make..

Don Coatney Posted October 24, 2011 Report Posted October 24, 2011 I agree. Replacement should be in pairs. Cup and cone. Quote
littlemo Posted October 24, 2011 Author Report Posted October 24, 2011 Don, Tim, et al. The situation re. the bearings arose during my conversion from drum to disc brakes on the front of my P-15. I had ( being cheap and trying to save a $$) taken Charlie's bearing #'s and cross referenced them to another parts supplier. Needless to say, when I started to place the rotors onto my spindles, I discovered that the inner wheel bearings, inner race was to large for my spindle. Soooo, I pulled the original bearings from my old hubs, and you know the rest of the story !!! PS. Yeh, I kind of got the feeling he'd be happier "flippen" burgers !!! lol, Cass, alias littlemo...

desoto1939 Posted October 24, 2011 Report Posted October 24, 2011 My old Hollander interchnage book should list the numbers on the bearings. I will check my book and post what I find. My 39 Desoto used timken tapered bearings. The NAPA guy needs to go back to school. Rich Hartung Quote
Don Coatney Posted October 24, 2011 Report Posted October 24, 2011 I dont believe the bearings for your new rotor are the same bearings for your old drums. I dont know what rotors olddaddy recommends but if they are for a 73-88 Mopar then you need to buy the bearings for that rotor not for a P-15 drum setup. Quote
Plymouthy Adams Posted October 24, 2011 Report Posted October 24, 2011 now that explains a lot..one must buy bearing for the lastest and greatest application...Charlie's numbers should have been good if you use the recommended/listed parts throughout the install..is this kit supplied with spacer/bush for the inner bearing? Do you have access to a vernier caliper to make the proper measurements and let Charlie know what is what..he I am sure will have the answer if you let him know the problem.. Quote
Young Ed Posted October 24, 2011 Report Posted October 24, 2011 let Charlie know what is what..he I am sure will have the answer if you let him know the problem.. Ya as long as you didn't pay with a royal bank of Canada money order Quote
Plymouthy Adams Posted October 24, 2011 Report Posted October 24, 2011 nothing like putting a little salt in the wound eh Ed? Quote
littlemo Posted October 24, 2011 Author Report Posted October 24, 2011 (edited) I apologize if I gave the wrong impression; the mistake was mine in trying to take the cheap way out, NOT Charlies. I had taken my old bearings with me when going by NAPA and that's when the issue of the "tapered-rollar-bearings" came up. After returnig home,the first thing I did was to "mike" the diameter of my spindles at the rear and front bearings. After picking up the correct bearings recommended by Charlie, I found them to fit exactly. The problem was in the cross- referencing to another store brand bearing, which ended up being too large for my spindles. Once again guys, a big thanks for all the help!!! Cass, alias littlemo... Moral: follow directions carefully !!! Edited October 24, 2011 by littlemo Quote
Young Ed Posted October 24, 2011 Report Posted October 24, 2011 nothing like putting a little salt in the wound eh Ed? Not the intention. Charlie my apologies if it was taken that way. Quote
