Deglazing a cylinder Part 1

[faffaflunkie]

Instruction like this is why we cannot build a quality automobile anymore. The dumbing down of America, part I.

[welshfluteplayer]

He probably blabbed his way into the job and just makes it up as he goes along.

[docvegas222]

retard! Way too high RPM's w/o lubrication & used solvent!

[darmhok]

this 'instructor' is a retard

no cross hatch pattern, WAY to fast RPM.

[pinkfloydeffect]

.....wow. This is why I dropped out of high school!

[musiclovr2]

is that chrome coated?, be careful if honing coated cyls

and a line hone is better

[efp1103]

Those rings would chatter like crazy if it was assembled. Im not sure this guy even knows what a cross hatch pattern IS

[arTurce1]

that he doing is rubbish!!!!

[arcanacelestia]

He gave that cylinder more of a circular hatching pattern and less of the cross-hatched pattern which is essential for lubrication to prevent the aluminium piston skirt scuffing dry up against the cylinder wall. It's a disgrace that someone who is so hopeless at honing should be teaching people how to do it. No wonder Japanese and European cars last so much longer than American cars.

[luvtomoko]

I feel sorry for the students.

[cash22sa]

thanks nicolasdamally im happy for the good info i didnt finish this video .. this instructor sucks and should be fired..

[dogg502]

HAHAHAHAHAHAHAHAHA I can see it now all these kids going home and destroying there dirtbikes and go karts using this guys shitty teaching that were paying for!

[fin781]

nicholasdamally, no one cares what u know. make ur own video. hater.

[abeepak1]

@fin781 lol funny, hater spotted! not nicholasdamally, but you, fin781 :D

[cobrachoppergirl]

someone needs to come up with a better engine design that doesn't require this or a dozen other things in precise mechanical tolerance... because doing this bullshit.. is just... bullshit.

[lazzer408]

He did it wrong. ONE FLUID STROKE OVER THE FULL CYLINDER AREA!!

[fordboy111591]

sounds like someone rapeing a monkey lol

[sliksspik88]

this looks like he needs some more schooling; kinda seems like he doesn't know what he's doing.

[virtu69]

4 The record he is just teaching the procedure and that engine will be properly honed later

[chris92Stang]

u are all DB's.. what he has done in the video is just fine.. someone is always qucik to slam someone because they are too bored, never had hands on experience or are just jealous. GET A LIFE people

[Spang06]

No...

You want to float the hone to get an even score on the cylinder walls. Solvents don't do that as well as oil not to mention the effect on the abrasive on the hone itself.

[LittleModig]

I pretend not to be a mechanic,how ever if you go to the whole trouble to do all this work,why not wait a little bit save the extra cash and send it to a machine shop is all worth it.they'll do the crankshaft,dip in,clean as new etc... my body was going to do it by hand w/a drill and the whole concept I couldn't buy it.time.......& I plan to keep this car for as long as I'm a live or pass it to my kids everything new.original will be 325es B

[johnny66o1]

this is horrible.. I can't believe you are teaching these student to manually hone instead of just s hipping it to a machine shop to be bored and honed properly and evenly. these poor kids will be dealing with cylinders not sealing their whole lifes because of you..

[elitecssplayer]

I disapporve your comment, I think it's good that this techer is teching these students how to manually do it them selves. And besides.. no body wants to pay extra money for S+H

[johnny66o1]

then move ot california where there is a machine shop ever half mile.

[elitecssplayer]

ok... lol

[tgore3]

The proper way is to just use a keyless chuck, lol

[Quebexicano]

Oh and the sound sucks in the video lol

[roady42]

He really isn't doing it right.

I would take it someplace and have a pro hone it.

The other thing is those things are coarse, I would use only plain cast rings after honing with that monster, it would wear the moly off a good set of rings by break in.

[Quebexicano]

You know what if your rebuilding an engine you should rebore it check the head for warpage and use plastigauge on your crankshaft we never do that, its all bullshit unless that engine was abused in that case i wouldent even touch it

put new rings valve seals belt and tensioner thats it and I never had any problems

most people dont keep engines for like 20 years lol

[marcoa2393]

povero motore

[NicholasDaMally]

I hope this guy is just a temp or something and not the actual teacher because it's obvious he does NOT know how to correctly deglaze and put a proper crosshatching in to a cylinder.

First mistake: Using an air gun. Use an electric or cordless drill set to low.

Second mistake: Using solvent as a lubricant. The use of solvent is NOT adequate lubricant and destroys the adhesive in the tool.

Third mistake: Uneven strokes. Always use smooth, even strokes through the entire bore.10-45 seconds.

[CrowOfHellsing]

are u a teacher or something?

[abeepak1]

@CrowOfHellsing teacher or not, what he is saying is right. this guy here would probably knows his stuff better than the dude in the vid

[efp1103]

@CrowOfHellsing He may not be, but hes absolutely right. The guy in the video IS doing it completely wrong. Thats a fact

[marek0086]

he said solvent AND trans fluid.

but ye it was total bullshit.... no idea how to hone.

and your meant to use a nylon brush after honing to clean out all grit.... NOT soapy water.

[Spang06]

You are exactly correct NO Solvent! It degrades the adhesive on the hone grit.

Use hone oil or a light motor oil.

Also, only run 5 passes each way and then look at the bore. If there are still deep scratches or scoring, get a rebore.

[marek0086]

this is the worst hone job iv ever seen!

Way too fast.... you're meant to use a cordless drill!

[ilovetotones1]

@NicholasDaMally lol damn i just finished reading a chapter on honing and your statements are correct

[NerdForMIT]

@NicholasDaMally You do know that on some air compressor there is a flow regulator valve for adjusting the amount of pressure going out the tank. you can lower air pressure and lower the guns rpm.
