RedRider Posted March 31, 2017 Report Posted March 31, 2017 So I put all new wheel cylinders on and replaced the front passenger drum and hub. When I put the wheel back on the passenger front the spindle now sticks out 1/2 inch farther than it did before and the dust caps don't fit anymore. Why would that be? Any help thanks Quote
RedRider Posted March 31, 2017 Author Report Posted March 31, 2017 The nut screws 1/2 inch farther into the spindle as well. Bearings are the same bearings that were in the old hub Quote
Plymouthy Adams Posted March 31, 2017 Report Posted March 31, 2017 (edited) replaced as in different than the one that was on there before the brake job? I think you need to do a few comparison measurements of old verse replacement..start with the diameter of the rear of the hub and bearing differences...physically check the depth of the bearing into the race of the replacement Edited March 31, 2017 by Plymouthy Adams Quote
RedRider Posted March 31, 2017 Author Report Posted March 31, 2017 I bought a NOS drum, the old one was cracked. The bearing sits farther in the hub. Is this a problem other than the dust cap not fitting back on? Why would the diameter of the hub be different on the two drums? Quote
Plymouthy Adams Posted March 31, 2017 Report Posted March 31, 2017 compare the race....could be just as simple as mismatched races..did the hub come with a race installed? did you install the race yourself? did you use a mic to compare the old race with the new before install....did you use an old bearing with a new race from the one in the newly supplied hubs...I am thinking total comingling of parts here....check the bearing again with the old hub and race...if you do not want to buy matching new unit then you will have to extract the old races and interchange them as per your description of the crime scene...it is hard to supply a definite answer here as only you have access to what is on hand and know in what manner you did the swap and what checks prior to the maintenance action were taken.

RedRider Posted March 31, 2017 Author Report Posted March 31, 2017 The race was welded or riveted on the NOS drum. They were made like that I guess. The old race was riveted in the old drum too. Same bearing from old drum and race was used in new one Quote
RedRider Posted March 31, 2017 Author Report Posted March 31, 2017 Example of what it looks like Quote
Don Coatney Posted March 31, 2017 Report Posted March 31, 2017 It appears you did not remove the bearing races from the old hub and install them in the new hub. Pay attention to the bearing race removal and install in this video as this applies to your hub. Quote
RedRider Posted April 1, 2017 Author Report Posted April 1, 2017 Races were already in the hub, wrong size Quote

A new drum with hub attached does not come with bearing races installed. I would think if you actually found a NOS (new old stock) drum/hub assembly that it would also not have bearing races already installed??? Now to the next question. Why would the NOS (that is supposed to be an exact replacement) drum/hub assembly have bearing races already installed in the hub of an incorrect size???? Bearings and bearing races are all the same size on P-15's. 1 Quote
Plymouthy Adams Posted April 1, 2017 Report Posted April 1, 2017 perhaps...and just spit-balling here.....NOS to the seller was NASTY OLD STUFF as in my earlier reply, when he said hub with race already installed the bells rang co-mingled... 1 Quote
RedRider Posted April 2, 2017 Author Report Posted April 2, 2017 I bought it on eBay, never again Quote

The old race was riveted in the old drum too. Same bearing from old drum and race was used in new one This doesn't sound correct to me . I have punched out races on these old drums many times . Are you thinking that the races should just slide in and out ? Correct me if I am wrong . Quote
RedRider Posted April 3, 2017 Author Report Posted April 3, 2017 No they won't punch out but the interior diameter of the races is too large- I think whoever had the drum before either put the wrong size in and couldn't get them out or had it on a different application. Either way they are in there for good, I bought a race pulled kit and they aren't coming out Quote
Don Coatney Posted April 3, 2017 Report Posted April 3, 2017 I have never not been able to drive a race out of a hub. Can you post a close up clear picture if this race that is stuck in the hub from both sides? 1 Quote
Silverdome Posted April 3, 2017 Report Posted April 3, 2017 (edited) In reading all of this, it sounds like one of the races are missing. Like Don said above post a good clear picture of the NOS hub front and back side with no grease and it should reveal the issue. Edited April 4, 2017 by Silverdome Quote
Dartgame Posted April 3, 2017 Report Posted April 3, 2017 In the event you have not done this before? You do have to get pretty violent with races inside a hub like this. A heavy punch and hammer are needed to get things moving. 1 Quote
RedRider Posted April 4, 2017 Author Report Posted April 4, 2017 I haven't done it before on a drum this old and crusted, but with the race puller kit and a hammer and a punch it should have moved. Luckily the guy I bought it from on ebay is letting me return it Quote
