Quite a few! The only reason I buy from them is their Lifetime Warranty. I wish I could afford Snap-On& MAC but more often than not I have bought from China or Tawain!LOL Of course for a Torque Wrench you must have a good enough quality for precision engine assembly. I really need a good dial bore gauge, but a Starret cost almost 700.00!!drewcrane wrote:i wonder how many things have been assembled by crapsman

I cant imagine many men bigger than you Pat Great news! The bearing clearances checked out perfectly! Right on the money! I was shooting for .0025 but it appears to be .002 fine! The extra .0005 would be perfect for a race engine but this thing is probably going to see a lot of street time. .002 is a perfect clearance for both extended street usage and some high RPM usage. A little tip, get some dull ended small screw drivers with a short handle. You know, the kind us auto 'geeks' carry around in our service shirt pockets this will help with the hardest part of this procedure. getting the damned main caps back off for a clearance check without gouging your nice new 4340 crankshaft! Then you can gently pry up on the main caps parting line. I had to use this valve spring puller, where the end curls up, I then inserted it gently and popped them out! It took me almost an hour to just remove the main caps!LOL Time to remove the crank, clean it again along with the bearings of the pastigauge, then lubriplate the bearings and install it for final assembly. The girdle goes on after the rods are secured to the crankshaft, this way I will have a little extra clearance to tighten the rod fasteners.patrick wrote:airfuelEddie wrote: BTW, the 4340 Crank weighs 72 lbs.

I would have loved to have helped, Eddie. Now that I'm getting older and smarter. You and I could have sit down in the lawn chair's, you could have a Tea, I'd have one of those Micro Brew's, and watch my Bigger and Stronger Grunt's do the work.
I quoted the range wrong Barc. The red is for .002 to .006 the green/blue is for another range,(s) which I dont currently know, used to, but it's many years. I would have used a good quality dial bore gauge with a 2"-3" range but have you priced a good one? Starret makes a nice one so does MAC and Snap-On or Goodson. But they are all over 600.00 for a machine shop quality gauge. I have some nice mics and snap gauges but snap gauges are + or - .002 or more. This is not accurate enough to check both main and con rod bores. The Pro's use a dial bore gauge. Someday I'll have to get a Goodson/Starret.fal308 wrote:It's been many many years since I needed to use Plastigage. I forget, what is the difference between red and green (and blue?) Plastigage?
