The Dilivar Studs Are Out

Jadams1 · Jadams1's Garage

All twelve Dilivar studs are removed! Used an oxygen/acetlyene torch to gently heat the case and they came right out. Now I'm ready to install the steel studs and reassemble the engine. Is the thread on the stud a standard 10M15. I wanted to run a tap in the case to clean out the hole.

10x1.5 it is.

That's a nice sight, jadams!
Be sure to protect those rods from flapping around, hitting the case and such.

Unless you're going to toss it into the back of a pickup truck and drive off-road, there's not too much damage that your rods can do just sitting there...

Well, even though you *are* writing a rebuilding book, I beg to differ. Many pros (and thoughtful amateurs) take great care to protect the rods from nicks, scratches, and abrasions. I use short lengths of rubber hose over the rods. It is easy to do, doesn't cost anything, and can prevent a potential failure of a vital component.

the case is aluminum, or magnesium..

the rods are steel..

Im not seeing how the rods can be damaged

anyway any stress risers can be dressed with some crocus cloth

Be sure to use a thread chaser to clean the threads, not a cutting tap.

KTL, I'm not having much luck finding a 10x1.5mm thread chaser. Is it the same as a flat bottom tap or medium tap? I own a 10x1.5 mm starter tap. What do I need to buy? I've looked in Grangers, McMaster-Carr and MSC.

John,

They're like these:

Thread Chaser Set

Never used them myself, but these guys are what you're supposed to use to clean your threads.

Any other options besides the thread chaser? I'm trying to keep the tool investment cost down and I was hoping to install the studs on Saturday.

ASt this point in my rebuild, maybe 8 weeks ago, I checked into this "thread chaser versus thread cutter" controversy. All of the professional mechanics I spoke with said "What?" Oh, you know, thread chaser, but not a recgular cutting tap. They said "What?" again. Then they said "I use a tap. What's a thread chaser?"

So, I used a tap.
