1968 Frigidiare Custom Imperial (Restoration)

[philr]

Joe,

 

It could have been made in 1966 too but it's a 1967 model. The "L" in the model number tells it. "K" is 1966, "N" is for 1968-70 and "S" is 1971-72...

Back at it.

Here is today's work, a partial reinstall of the mechanism and wiring.  New gasket cut for pump and new seals in place.  Having trouble sourcing a bearing, Grainger ordered one but the outer diameter was wrong, went to a local bearing shop and they gave me what they thought would work, said it may be a little tight.  Well the tolerances on this don't allow for anything even remotely too small on the inner diameter.  I'll be going back to visit them tomorrow.  Suggestions from people who have done this before or who know a lot more than me are certainly appreciated and respected as I navigate this process.

Love the washer!

I'm sure Phil will chime in, but I think he mentioned that the lower bearing was not a standard size.  What was the MFG number on the bearing? 

 

Original part number was 7524183.

Hi Ben,   On each side it simply says NICE   PHILA   USA   I would assume this is the NICE bearing company in Philadelphia.  I don't imagine it's standard either.  Grainger said they probably could get it but to try Bearing Distributors.  I mentioned to them having a new one made custom, I also considered that it could be rebuilt.

Hey Joe,

 

I have my suspicions on Grainger being able to get the bearing, as well as most MRO businesses (MSC, McMaster, etc.).  When you went to the local distributor, did they indicate what the following sizes were?  Bore diameter (ID), the outside diameter, and the width?

Photo breakout excellent and re: Reply #18

Though I'm lost in the jargon, the breakdown and accompanying photos are great - and I'll second Frigilux's comment in reply #18. Very nice looking machine.

 

[joelippard]

Ben, they did measure it with calipers but I don't have those numbers, they say the outer is metric.  Grainger did get one in with the proper inner diameter.  I suppose if it came down to it I could make a surround to compensate but with this being a rapidry machine that bearing is going to get a workout.

 

Thanks ovrphil for the compliments.  I am purposely being detailed about this for the forum archives, hopefully someone else will be helped by it someday.

Joe - your findings are similar to what Phil mentioned to me in a PM.  He said that the outer diameter was metric but the bore diameter was a standard size.  Odd that GM would spec a bearing that could have been easily fitted in a casing that could have been sized accordingly.

 

Did you grab the PN/SKU of the bearing that Grainger originally sold you?   Phil had found a possible replacement with an NDH number of 77504CJ.  If you drop the CJ that crosses to a 6204ZZ, but we'd still need to know what the sizes are to see if something matches up.

 

EDIT - the 6204ZZ translates into a 20MM bore/ID, x 47MM outer diameter, and a 14MM Width, double shielded.  Grainger PN for the shielded for NTN is a 1L017, and the sealed version was a 6L026.  I'm wondering how far off the original outer diameter is from 47MM.

Ben, here is a link to what they got in.  I never bought it from them.  I paid the local bearing shop $3 for the one they sold me but the bore is definitely not correct.

Ok, that's a start.  The 5u498 has a 20MM bore, so we know that's good.  The outer diameter lists at 42MM, vs. the 47MM we saw from the possible cross Phil found.  Also, the width is slightly smaller at 12MM, vs 14MM. 

 

If you have a metric ruler on hand, you could get a rough estimate of both the outer diameter and the width. 

 

[joelippard]

I don't have one of those Ben, but let me be sure that we do know for a fact that the correct (original) inner bore should be 20mm?

 

[swestoyz]

After going through the Rollermatic parts stash...

... I found an NOS 7524183 bearing!  We can confirm finally that the number Phil saw on his box is probably the correct number - the New Departure number of 77504CJ.

 

I measured the bearing and came out really close to the measurements from the cross reference bearing number - the 6204ZZ.

With a cheap metric ruler, I measured out a 20 MM bore, 14MM width, and what looked to be a 46 or 47MM outer diameter.   The Grainger 1L017 or 6L026 should be really close.

Thanks so much Ben!  You're great man! I think I'll order that one you linked too since it will only be $8.  Even if it didn't work I'm out nothing and I'll just try the Grainger part numbers.   If it does, then I'll be ordering a lot more for my stash.

 

[philr]

Let me know if that works, I'll order some spares too!

Edit:
I just checked the metric dimensions on mine with a cheap electronic caliper (a bad bearing removed from a machine in a new Delco NDH bearing box) and the inside diameter is 20.64 mm, the outside diameter is 47.00 mm and width is 13.99mm.

The 20.64 translates into 0.8125" or 13/16"...

On the box, there is the Frigidaire part number: 7524183, 1# 77504CJ and "XY1343 C"[this post was last edited: 2/21/2014-02:07]

My bearing is from a Canadian-made Rollermatic machine and it says: "SKF MADE IN CANADA" and the numbers are really hard to read but it seems to be written "K7004J9".

There's no way to fit a 20mm I.D. bearing on that shaft. The place who sold me the wrong replacement bearing suggested that I have the shaft machined to fit that smaller I.D. bearing they sold me but I showed them the shaft and they understood I couldn't do that! Then I asked if it was possible to have the I.D. Of the bearing bored out to 13/16" and they told me it wouldn't be good... So I had the used bearing back in place and just replaced the upper Torrington bearing which was bad.

BTW, Joe, can you show a picture of the old upper spin bearing you have on your washer?

Grasshopper....

...I remember the day when you were so afraid of these machines and now you're an expert! Very proud of you!!!

 

[swestoyz]

I have a spare '66 2 speed Rollermatic transmission sitting around.  This weekend I'll tear it apart, pull the bearing, and compare the original (bad) one to the NOS replacement I have, and take some measurements.

 

I find it odd that the ND 77504 NOS replacement crosses to an industry standard number that has a bore too small.  I should note that all Rollermatics from 64-69 used the same 7524183 lower shaft bearing.

Thank you for this instructive posting. BTW I'm glad you're keeping the commercial gray top to the Jet-Cone; looks very spiffy.

 

[joelippard]

Phil, does this mean that what I have ordered will not work?  I don't have the top side of the machine opened to get a picture of the top bearing because it doesn't seem to be the problem.  I'll have to see how things are up top after I complete the bottom end work.

 

Ben, thanks for checking into that man, you've gone out of your way to be helpful to me.  Thank you!

 

Mark, I remember those days too!  I have no fear of any Frigidaire now but I will say that pulsator nuts and water bellows never seem to be my friend!
