Thank you John, for the extra time you share with everyone... The regular people! Like me love this stuff, Working in a Auto Manufacturing for almost 30 years, there's nothing we do that compairs to what you do! Keep up the good work... Hope your Holiday is great!
As mentioned, you only use torque plates on aluminum Evo and Twin Cam cylinders. Engines with short cylinder head bolts dont need torque plates since the headbolts dont compress/distorte the cylinder.
@kvadrupel Not so!I have honed hundreds of cast iron HD cylinders and can state without a doubt that torque plates should be used in all cases.The torque spec.(65 ft. lbs.) for the iron cyls. is approximately 25 ft. lbs. greater than the Evo-TC spec.,and is distributed along a much smaller vertical area.The studs running through the entire length of the cylinder and head distributes the torque over the entire assembly and actually causes less distortion.This is largely why they do not leak.
@07blackdog Yes I know that after the evo was introduced, some builders started using torque plates on the older non trough bolt system engines with iron cylinders. At least when reboring. In my opinion, the need for torque plates is way more important on the evo and tc engines because of the less stiffer aluminum comined with the through bolt system. I guess that torque plates wont hurt on shovelhead and older cylinders. I just think thet Vector6977:s comment was overly critical in this case.
@07blackdog The main reason why evo and tc:s are less prone to gasket leaks, is the bigger clamping length. The long through bolts provide better preloading than the stud/base head/bolt system, this better maintains the pressure on the gaskets. Another factor is the larger thermal growth of aluminum, since the whole cylinder is clamped on evo and tc:s, the total thermal growth of the cylinder helps increasing pressure on the gaskets.
Ciao jonh sunnen technical data microinch / 40 = micrometer 28/40=0.7 38/40=0.95 ok? sorry my bad english john i am italian job for sunnen EC3500ASC SUNNEN1805ASC SUNNEN1804 AND PORTABLE HONING TOOLS my passion is old motorcycle (harley davidson WLA ecc) you are a very good to work by SUNNEN TECHOLOGY where can i find your complte handbook engineering? GRAZIE ciao
i thought that most machinusts hone about 5to 10. Even though in my opinion you are the best i have seen at engine machine work. Why would you not bore it out and then final hone? its just a really good question and not to contridict anybody. keep up the great videos
I'm wondering the same thing. I've recently had an MB jeep engine taken out .020"o/s. They bored it, then final honed it. Why not do that here? Again, not questioning your competency, just asking why it can be done that way.

THANK YOU John, good light, good sound, and you explain the process as you go.
Not to many know how to do a good video on machining. Thank You Chris aka FinnMacCool869

gaaaaaaaa!!!! no torque plates on HD cylinders. Damn you will never get a round cylinder on HD cylinders with out first installing torque plates.

New n learning. But are you pouring oil what are you poring in to the cylinder?

Why didn't you use the torque plate setting in the corner?

you only use torque plates on evo and twin cam h-d engines.

When replacing piston rings, what kind of grid would you hone to allow liner and rings to break in ?
I want to buy one of these tools to use with the cordless drill to do my old tractor this summer.
