Flex Disk Replacement

[stickandrudderman]

The centering bush often does wear, as does its aluminium (aloominum) carrier. They are also often missing altogether!
It is very important that this bush is in good condition otherwise the prop can vibrate horribly and cause premature wear to the flex disc.
As for alignment, I'm reluctant to give away my trade secrets but I'll tease you with this thought: Laser pens are a couple of quid.

Thats what I use for wheel alignment. I aligned my old Ferrari front end with a few trigonometry equations, a tape measure and a laser pen, then took it on a 3,000 km round trip.  It drove like a dream with new Vredestein Classics.  One day, when I get some time, I`ll complete the write-up and post the procedure.
I can`t imagine, however, where one would place the laser pen on the engine side to align the drivetrain.  The prop shaft is a given, I think.

Tomnistuff, I will look forward to your alignment write-up.

It seems that when I start to put something back on the car, I find that it needs repairing first.  As I mentioned in a previous post of this thread, I ordered a flex disc kit on Ebay.  Well that went over like a t__d in the punchbowl.  The JURID hexagonal flex disc kit turned out to be a Febi circular flex disc and nothing else.  The seller doesn`t respond so now I`ve opened a dispute which has been escalated to a claim.  More delays.

While waiting, I started putting together the rest of the driveshaft stuff, only to find that before repainting it, the restorer apparently degreased it and sandblasted it.  That did a wonderful job leeching all the grease out of the double sealed pre-packed deep groove roller bearing inside the aluminum housing that is supported by the pivoting eccentric rubber donut.  It rattled like a baby`s toy.  More internet research.

Fortunately the bearing, once I got it out, had a number faintly paint-stamped onto edge of the outer race.  SKF 6006 SRB, as or something close to that.  I measured it and found the 6006 2RS from almost anybody`s catalog matches the size.  The 6006 2RS, which, I suppose, means something like double-roller-sealed seems to be the new way of numbering it.

My local NAPA store wanted $56 for one.  Most places on the internet wanted from $15 to $35 plus about $35 shipping.  I finally found a local industrial fastener supply shop that wanted $17 (with a minimum order of 5 pieces) - that`s $17 total for 5 bearings.  They are made by some company named Bearings Limited but they look well made and come sealed in a cellophane bag inside a tiny box that says don't open it until you are ready to use it.

I've installed one and the housing spins beautifully and silently.  Now what do I do with the other four?  I've decided to sell them.  I'll list them in the Items for sale section.

So finally the bad experiences have been lightly compensated by a pleasant one.  I wonder what's next.

NO!  I`ve changed my mind.  I just checked out shipping costs from Canada to the U.S.  Anyone who needs one, especially in the U.S. should go buy one at an industrial parts supply house.  They will be dirt cheap ($3 or $4 each) and way, WAY less expensive than shipping costs.  Good Luck.

Tom,

This is a common bearing available most anywhere. I always check with ebay when I need a bearing. Most times they will have these in "buy it now" for pretty cheap and they are brand new in original package. You can usually get FAG or SKF brand if you shop around on the ebay site.
