Perrin Oil Cooler - Mocal Plate Spacer Bolt - Damn Bolt
 

Does anyone have a good resource on a 27mm socket that will actually fully fit around the spacer bolt that holds the Mocal thermo plate down with the oil cooler spacer?

Every time I have to unhook the oil cooler, I have to sacrifice a bolt because I cannot find a 27mm socket that will fit around the whole bolt.

Anyone else have this problem?

Here's a pic of the plate and bolts for reference:

Harbor Freight sells a deep impact socket set that goes, I think, to 32mm. Check and confirm the 27 is in the set. I suspect it is.

I did check harbor freight - the depth isn't the issue - it's the room around the sides of the of the bolt where i'd need a thinner than average socket to fit. I'm just wondering if anyone else has this issue?

Thinner on the outside diameter correct?
Because the galley prevents you from sliding the socket over the bolt?

Google this specifically. "Thin Wall Deep Socket"
Hope this helps.

Hmm - I did google thin wall sockets, but it wasn't any thinner than my current 27mm. Maybe it's because it's a 12 point, where 6 points are thinner...

I took a 27mm socket to a local machine shop and asked them to thin out the wall on a lathe. Really quick/cheap/simple. I think I paid ~$10.

If you get the good-buddy deal then toss your guy an extra twenty. If you keep going back, they'll eventually have to invoice the work. I have a pile of one-off special tools.

as a last ditch effort I have chucked up a socket in a drill (if socket is too big or drill to small, us an extension) and used a bench grinder to thin out the wall by running the drill to make the grinding even.
(chucking the socket in a lathe and using a tool post grinder is the right way.)

Fucking Brilliant. I don't know why I didn't think of this. I have a decent bench grinder - I don't know why this never donned on me.

Thanks guys!

wear some safety glasses....

a couple of things to consider:
do it slowly to not overheat and loose the temper.
do it at an angle to save as much steel as you can and still get into the casting.
and finally, grind or belt sand the end of the socket to remove the easy start taper, you want as much engagement as possible.

I'll just be glad to not have to destroy a bolt everytime i need to take it out. https://s33.postimg.org/jprhzajcv/20171121_221730.jpg

Quoted for emphasis.

As you grind the workpiece, dip it in water often to keep it cool. Blue means it got too hot.

First remove the easy start taper. Then chamfer for clearance.

Thanks, ls1ac!

BRUH!

It doesn't need to be much more than hand tightened. Consider it similar to tightening the oil filter itself.

As the oil filter is tightened, it adds to the compressive force of the adapter gasket.
