Today we're modifying the 4.2L #Jaguar crankshaft for our customer to ditch the old leaky rope rear main seal for a modern two-piece teflon lip type seal.
I misspoke in the video, this is for a 1968 engine, not 1966!

This is the route Hoovie should take for his e type jag. Excellent work!

My thoughts exactly... someone needs to show this to the wizard

@jsimsgt96 Год назад

@Volksguy1970 Год назад

I'm guessing its his. Always possible that its someone else's 1966 Jaguar 4.2L but I'm guessing its Hoovies.

Professionalism and excellence are a delight to experience. Your shop and your expertise are extremely impressive. So is this channel. Thank you kindly and best greetings from Germany.

@elmerwilliamson1970 Год назад

Best part of your videos is the relationship you and your dad have. Cherish the times you guys have together. My dad was a logger, and some my best memories as a kid was working with my dad and my uncle, riding in the log truck, being out in the woods with them.

@JohnnyAFG81 Год назад

I wouldn’t loose sleep about the rods not being equal in weight. I’m quite certain this 4.2 Jag engine will run like a dream.

@michaelennen3432 Год назад

You keep your crankshaft grinder really clean - I respect that very much. Awesome to see machines being cared for.

@raycollington4310 Год назад

Of all the machines in your shop, IMO mastering the crank grinding machine would be the biggest challenge. Thanks as ever for the video.

Wow!! That balancer setup is flat out amazing! Alot of people install harmonic balancers but that setup you have there is called doing it right! That is super cool

@craigm.9070 Год назад

Thanks for the update on this Jaguar project; real shame to hear about that somewhat extreme imbalance issue on the rods. I guess you could bring the ends a little closer but like you said, structural integrity becomes the issue. Appreciate your time!

@pbe6965 Год назад

These engines can't rev high due to the long stroke anyway, so it might not have that much of an impact. But maybe they could also rev slightly higher if they were better balanced from factory ?

@Stoney1985 Год назад

The long stroke certainly doesn't help with higher RPM, however a 14 gram difference probably partly plays a helping hand in the reason they are kept to a lower rpm rev limit. As a machine shop that takes so much pride in their work, I wonder how they feel not weight matching everything.

@miceinoz1181 Год назад

@stephencurry8552 Год назад

As I watch these, I find that I have a smile on my face. Wonderful for me to see in detail these processes. Most people do not understand how being a master machinist is as much about the maths and science. As it is art. You watch the man ever so gently persuade the knobs of the machine he is using. That is the man communicating to the machine, and the machine responds by giving the man what he is asking for.

@jjg7696 Год назад

Quality, Service, Attention to detail. Absolutely incredible work.

@theprojectproject01 Год назад

I'm always astounded by the precision and accuracy that's achievable with these machines. They certainly can't be cheap, though!

@scottallpress3818 Год назад

It’s a shame that cleaner is about to retire , he is showing good progress and would have made a great machinist !!

@robertwest3093 Год назад

I've seen mentioned in several places that OE engine manufacturers set their balance tolerance as high as 80 grams. That is over 2.5 ounces! If that is the case then having an engine balanced to within .5 grams before assembly should make it as smooth as a sewing machine.

@doggfriendly Год назад

We just converted the rear seal housing of a Ford fontana "cleaver" block, from 2 piece rear seal into a 1 piece rear seal. Thats probably the one and only fontana block I will ever work on in my lifetime on account of they are a low production casting.

@georgiafan6618 Год назад

Hopefully this Jag engine when it’s finally rebuilt, will run much better than when it was factory - and the rear main won’t leak! Love these videos. 👍

@r.d.riddle2068 Год назад

If your crankshaft grinder is 3-phase, you can always reverse it and put material back on, right? Or does that only work with lathes? This is a great channel. I have a greater appreciation for crankshaft grinders (The machinists, as well as the machines) than before. You've raised a pretty good old school machinist as well. Pretty clever fix for a chronic Jaguar problem.

@vannorman1116 Год назад

Is it important to have the crank turning into the wheel versus with the wheel

@trojanyacht2518 Год назад

Final grain, or surface texture is the result of this. You want the material to not act like a file when rotating on the bearings. Great point!

@TeKedaFlamasb Год назад

Your videos are very good. They are very professional. I would like to know what is the use of what the connecting rods go through. Is it a demagnetizer? Greetings from Argentina

@waynep343 Год назад

Is there enough rod bolt sticking thru the nuts to grind it off to get the big end weights closer as well as grinding the inside ends of the piston pins to equal the small ends out of the final assembly.

@michaelv3340 Год назад

Well, that fixes one of the many issues with old Jaguars.

@michaelgalimi940 Год назад

What are you guys doing it won’t be a Jaguar anymore if it doesn’t leak oil 😝 Beautiful work guys

@TheFlash-cat Год назад

To correct the rod issue you can put bob weights on the crank matching the irregulat rod weights(not usually done on a straight 6) and balance the crank to rods...while odd this will work...you all so keep the rods in moving couple pairs with the lightest 2 and heaviest 2 .

@eformance Год назад

The nice thing about inline engines is that you don't need to make bob weights, so the customer's decision on the rods won't hold you up!

@cameron878 Год назад

I always get a kick out of your text measurements of what your cleanup/tear down guy says.

@keithjurena9319 Год назад

Balance rods by adding weight to light rods. Longer bolts for large end, plugs in pin ID.

@sammcbride2464 Год назад

I hate rope seals. :( Pontiac 455 owners routinely upgrade a rope seal to a Chevy 454 rear main seal. My rear main leaked almost day 1 after a rebuild.

@johnnyohanian4237 3 месяца назад

I was gonna ask the question why don’t you weld the cracks and then you already answered it. But I have to admit, it kinda leaves me unsatisfied knowing that you left cracks there. maybe it’s just psychological or something like that. But I defer to your expertise and wisdom, you guys obviously know what you’re doing.

That was quite a bit of material removed. How much can be removed by grinding before lathe roughing becomes faster option?

@housepumpinpc3983 Год назад

You guys did well. A 67 probably wasn't balanced so tightly. I'd roll with those rods but it's not my build. New rods? It's only $$$.

@JAMSIONLINE Год назад

I’d roll w/ the rods as well. Other options are finding used rods (good chance balance will be further off) or aftermarket, which are expensive af for this engine lol

@williamgrissom9022 10 месяцев назад

Grinding a rare and expensive crankshaft must be frightening. One oops and an expensive boat anchor and angry customer. Wheeler Dealers had a episode where they similarly installed a modern rear crank seat on a classic British engine, a 1-piece type which slips over the crankshaft.

@Volksguy1970 Год назад

Could this be for Hoovies Garage 1966 4.2L leaky engine ?!?

@pascalhumphrey Год назад

how does grinding effect the hardness on the crank or rods? They are heat treated to a certain extent right?

@nerd1000ify Год назад

So long as you don't grind away so much metal that you remove the hardened outer layer, and you use lots of coolant to avoid overheating the work, it should not affect the hardness.

@pascalhumphrey Год назад

@@nerd1000ify how thick is the hardened layer?

@nerd1000ify Год назад

@pa h depends on the engine, but could be anywhere from 0.75 to 2mm.

@stevenm3141 Год назад

My question is how do you true up the crank grinding wheel? Is it done in the machine and how often does it happen?

@nerd1000ify Год назад

Probably using a diamond dressing point in the machine. You have to do it any time you re-mount a wheel (as it will lose its concentricity with the spindle), or if the wheel goes out of true on its own. Usually you would also dress the wheel occasionally to remove 'glazing' of the wheel, which is essentially caused by the grit on the surface wearing down and becoming blunt.
