Valve Spring Modifications

I have this micrometer Summit Racing® Valve Spring Height Micrometers SUM-900032 - SummitRacing.com and I bought these retainers Howards Cams Chromoly Steel Retainers 97132 - SummitRacing.com. Only problem is that they don't sit on top of the micrometer like they should and it sits down like shown in the picture and giving me incorrect readings. Any suggestions on a different micrometer that will work?

Thanks
Shane

Can a mod change the title to like valve spring micrometer? i wasn't thinking lol

I've used a 'snap gauge' for this before.. Not the best but it works. You have to make sure the retainer is pulled up tight on the locks and setting straight.

It would be cheaper to buy a large dia. washer that has a hole just large enough for the retainer to sit in and large enough OD to rest on the mic, take your measurement, then subtract the thickness of the washer.
After buying bee-hive springs I asked the same thing on this site a while back and someone suggested the same thing and it works fine if you don't mind a little subtraction.

Get some old valve spring shims. They come with many ID to fit the retainer and are a consistent thickness.

I've used a plain micrometer, I wouldn't trust it to the .001" but for .005" its fine, and most springs are precise enough for that accuracy difference to matter.

Sorry,
Late night. I should have said add the thickness of the washer to your mic reading to get the actual height. Just don't forget to do it for each spring, or mic reading. PIA but it works. I double checked it against a pair of calipers and the difference was negligible, especialy on spring height.
Come to think of it, I think I used a 0.060" spring shim and opened the hole a little.

you dont need to add shims or anything. Read the instructions.There is a certain dimension you add if you use the 1.250 retainers. Im not sure what it is as my Hite-Mic is in the shop and its cold out. Ill look in the morning. That is a real cheap mic. Besides you cant measure any bigger than 1 1/2 retainers and 1.4 to 1.8 installled height Buy one from Goodsons.Bout a hundred bucks.Steel and accurate. Mine is the original Hite-Mic brand.Had it since the70s.
