SupercarSunday May 3rd

[Doug Liedblad]

Hayden's car is running and he is itching for a drive.

Anyone else up for it on May 3rd?

SuperCarSunday with short blat to follow, maybe the Rock Store via Stunt Road or someplace else?

Well, I better get going with that idler pulley repair. Tentatively, I will be there.

[Doug Liedblad]

Can't you make what you need on your CNC machine?

Or just use Duct tape and gum?

That is the plan, I mean the CNC machine with some lathe work. I have the new bearing already and an aluminum rod as well.

I tried the tape and gum stuff before in the form of a a hard polyurethane idler I made first. But the idler (it is pretty small diameter) can spin at 15,000+rpm and it exploded on me on the Infineon track many years ago, chipping a piece out of the adjacent timing belt idler and ruining my track weekend. I guess I will stay with an aluminum pulley.

Maybe. I was planning to go to the Chino Planes of Fame airshow, but I suppose I could do that Saturday instead

Ah, reminds me....I had promised to go to the airshow and I can not do that Saturday. So I guess I have to bail out from the SCS meet and drive. But I will go and repair my car nonetheless.

[Doug Liedblad]

Anyone besides Hayden and myself?

Gert, did you fix the car?

Randall, if you are going to the airshow, my advice is go with Gert.

[slomove]

....Gert, did you fix the car?.....

No and I am ticked off. I had the new bearing but damaged it (possibly, but don't want to take a risk) when pressing it in.
Since it is cheap I ordered a new one and now Amazon Logistics misplaced it when shipping. I hope I get it tomorrow.

[Doug Liedblad]

Did you try the local auto parts store?

Or Motion Industries which are sometimes open Saturday in the AM.

[rzempel]

It doesn't appear that I'll make it. every schedule change this week is yielding unfortunate consequences.

[prabjohns]

Wish I could be there, just got back today from 5 weeks in SE Asia and have to get my ducks in a row at home.

[Doug Liedblad]

Vacation or working?

I did not but Amazon finally delivered with 6 days instead of the promised 2 days. Idler is finished, just need to install now. I changed the retainer from a circlip to 3 M5 screws and hope they will hold the bearing in place (double row, angular contact bearing).This pulley is 50mm diameter x 22mm tall.

Loctite?

[slomove]

I had the circlip and Loctite on the old idler but somehow it worked itself loose over 30k miles anyway. I suspect it gets pretty warm when running and the expanding aluminum pulley separates a few microns from the steel bearing that has less thermal expansion, destroying the glue bond.

But I seated the bearing with threadlocker gel on this new one anyway, just to be sure.
