71 brake rotor inner bearing seal

[Tony 73]

Assuming I do need to put a seal next to the inner bearing for my brake rotor. I got brand new rotors. The old rotors did not have a seal.

Yes, definitely need a seal otherwise you'll get grease on the brake pads.

Thanks for reply mate.
So pack the new bearing with grease, then place into rotor, then get seal and using a block of wood knock the seal into place?
Just watched a clip on youtube of a guy doing this for an A body.

 Hey Tony,  I'm relatively new on here  and never posted on your epic rebuild. Your car was running,  so all your hard work and kudos were handled long before me being here.
  On your wheel bearing,  good thing you posted a picture.  L68149 bearing is for the 73 up spindle,  and the 71-2 bearing and seal are smaller diameter. 
You don't have time to wait for the wrong parts.
I guess maybe check the spindle/ bearing interface as there's a chance you do have 71 spindles,  but 73 rotors and bearings.  Cheers.

That's about it unless you have a seal installer which is better.  You don't need to "sink" the seal below the lip of the hole in the hub; flush works.  Test fit the seal on the spindle shoulder though to be sure it's the right size.

Thanks for reply mate.

Thanks for the feedback guys  .
Popped into town and got 2 seals but got a feeling that when I brought bearings I would have brought seals also. Will hunt through my shed.

Hay Mr Cuda,
Just clicked onto what you are saying. I do have L68149 bearings and they fit perfect into my rotor, therefore have 73 up rotor, and rotor fits my spindle so must have  73 up spindles.
Will do search to see visual difference  between spindle years.
Big thanks

Came across this clip, realise not e body but think it still applies.
I got the larger shaft spindle, mine measures the same where inner bearing fits and my L68149 bearing fits perfect.
But my rotor is identical to the middle one in the clip, has tall lip and machined down side.
When fitted together it all seems to work which seems strange 
The local parts place that I got my rotors from has the later rotor in stock, will contact him and swap rotors if need be.
Dam , there is always one more hurdle to jump.

That video  sums it up. Having a 71, you might be buying parts for a 71.
Just wanted to make sure you got the right parts before everything was greased up.  I wouldn't think everything would be readily available for you.
Personally,  I like the 73 up spindle,  and it allows you to use the 11" rotor,  if you have the taller caliper brackets.
The other give away to year is the dust shield.  73 up are galvanized and corrugated,  71 are black and smooth.

Hopefully you have downloaded a Factory Service Manual from the Resources section of this site. If you have, just go to the bearing section and look for servicing disc brake bearings. It gives you a picture and procedures and torque specs to do this service.
Your picture shows the good HD reinforced, 1 piece (73 & up bearing size) rotor.

Thanks guys , appreciate the input.

I got hold of the guy how runs a business  NZ MuscleCar parts, and is local. Went out and saw him and I have come home with the correct 72 up rotors , will return the 72 down ones that I have had on the car.
Will need different seals which is next problem.
As hard being in NZ as means ordering most parts from USA sites like Rockauto etc.  All part of the fun.
