John Deere Alcohol pulling camshaft regrind

[@alexgillies4183]

Thanks for the interesting video, I hadn't heard of broaching lifter-bores, sounds pretty radical!

[@PowellCams]

Glad it was helpful!

[@AntalopeAUT]

Dang, with the amount of knowledge, thought and loving care you regrind these camshafts, this one is gonna be pulling like a proper beast again :) I also love seeing this kinda oldschool machinery being used . Greetings from an impressed Austrian machine-tooling engineer, many thanks for showing and teaching ! All the smoothest to youse !

[@PowellCams]

Awesome! We appreciate the positive word!!

[@j.sarnak1391]

Love all types of automotive machining, I retired as a manufacturing machinist, thankfully I did mostly 1st piece or small quantity stuff so I am like you always willing to dive into the strange or odd job. I usually don't comment much just hoping to help the new channel get traction

[@PowellCams]

Ty, I really appreciate it

[@Xkekeskfndsmw]

How does this guy only have 761 subscribers!? This channel is awesome, and he does such a good job describing/explaining things.

[@PowellCams]

The channel is only 2 weeks old, check out our primary channel "powell machine inc"

[@lazyhoundracing9621]

Lots of learning going on here. Thank you for your time.

[@PowellCams]

My pleasure!

[@Tshade67]

100 psi, That's almost 7 atmospheres! It's like a 350 Chevy putting out the power of a 2,380 cubic inch engine. Great video, thanks!

[@fastst1]

Likely the cylinder pressure to make that boost is in and around 100 psi as well on the exhaust side, on a big 5 inch piston you're getting close to 1700 pounds of force to push the exhaust out. You can see why when they blow they split the block in half usually

[@PowellCams]

Great point!

[@skylinefever]

I like this. I always find tractor pulling inventions to be interesting.

[@PowellCams]

Definitely

[@Drmcclung]

This is a cool video I haven't seen anybody else on KZbin do! Ran into a very similar problem with the last BBC I worked on a few years ago that chewed up a couple roller cams. In my case it was inconsistent spring pressure spanning all 16 valves, springs from a well-known vendor and it ended up roaching two expensive cams. A spring scale is one of the best investments I've ever made as an at-homer

[@PowellCams]

Absolutely

[@Lloyd973]

A really nice educational channel. Great place to learn something.

[@PowellCams]

Glad you think so!

[@carguy3504]

All videos are great hats off to you for doing it. Like to see how you make your masters and what reference materials that you use .

Pretty neat to see something different. Would be interesting to see how you make the master for the lobes.

Thanks for the idea!

What type of coolant do you use grinding cams.? Sorry for the bother ,you guys and gals make awesome videos

[@petercole2339]

Very cool! I work at Logo's.. the shop that prints shirts for yall in Anderson!

[@PowellCams]

Awesome! Great job

[@MarineGrunt]

Are you going to correct the lifter bore issue that buggered the cam as well ? How much material is left to make the correction ? Or is it an simpler issue of relocating the broached keyway and correcting the bore to crank relationship ?

[@PowellCams]

No, the customer was getting that done

[@stephenbaker-ix6dx]

What do you use for a master on custom cams? Do you have to make a new master for every cam profile? Thanks

[@PowellCams]

Yes, if we don't have a profile to fit a application we will have our lobe designer make one.

[@ronthepainter3313]

Sometimes doing the oddball stuff makes you think differently about the jobs you normally do.

[@PowellCams]

Definitely

[@Logan880121]

You have a very cool cam grinding machine, can you show us around and tell us how it works? Great work.

[@PowellCams]

Will do

[@leebornaman5508]

Is the grinder just free following the contour or is there a indexing guide to limit the travel? Fascinating.

[@PowellCams]

It follows a master profile

[@StrykerHP]

Job well done ,, Really enjoyed this

Im sorry, I couldn't stop laughing at Hot Rod John Deere 😂😂😂😂😂 Im in cow country and JD is last thing you think of when ya say Hot Rod. Maybe they should send you head also to match up the whole valve train set up spring pressure etc

[@PowellCams]

Lol

[@frankkoppen7281]

was thinking pushrod deflection..at that boost level..getting ext. valve off the seat ..should be the most stressful condition.

[@PowellCams]

Correct

[@leebornaman5508]

And do you build that profile (plate?), or preset an adjustable follower? Thanks.

[@PowellCams]

Yes each lobe design is a master plate

[@jim8027]

That wasn't as bad as it looked. I bet that cam cost a pretty penny. Nice to see you get to work on a quality piece. On a side note, I saw a video of a compound turbo setup on a pulling tractor, that made 300 lbs of boost!

[@PowellCams]

New it was 2k

[@larrychristopher9147]

Can you possibly video setting this machine up? Is it following a pattern cam, is wheel pressure regulated by the spring on left side? How do you assure your wheel is dressed square? Great videos

[@PowellCams]

We have videos on that

[@jeffallen3382]

With that massive amount of a lobe lift, would the angle of the lifter bore be a concern with side loads? Causing the lifters to cock in their bores? Just thinking out loud...

[@PowellCams]

Big base circle and large lifter wheel (.910) help that issue alot, we have bbc's with same lift and much smaller base circle and lifter wheel with no issues.

If you had to weld it, what alloy filler do you use? And do you machine the surface first like you need to do with a spray weld or just clean and start welding?

[@jamesdungan6198]

Is that because the ramp is so massive

[@PowellCams]

I don't follow you question, can you elaborate?

[@jamesdungan6198]

@@PowellCams is it because the ramp is so steep that the lifter floats at the top of the ramp
