Title: Now That's a Hemi! or how I cut apart a Guzzi motor
Post by: canuck750 on March 21, 2019, 03:57:09 PM: I have boxes of junk Guzzi parts, enough to build one motor, but suitable for display only, cutting into the beast to build a cutawy motor, maybe make it into some kind of coffee table ???

Getting started. It's slow work setting up the milling table and making brackets to hold the parts tight while I cut away. Staring with a band saw and finishing of on the mill.

I should have cut less than 90 degrees, I need to 'glue' the spark plug and guide in place, any ideas what would hold them in place??

Post by: Knuckle Dragger on March 21, 2019, 04:45:22 PM: Love your work, cobber. Where some may see wanton destruction, I see 'Art'.

As the previous poster suggested, a neodymium magnet drilled & glued into the (hidden) threaded section of cylinder head should provide a fairly staunch magnetic grip on the plug, but still allow it to be removed & replaced.

The valve guide is more problematic. Brass?? isn't magnetic & aluminium alloys have low melting points that prevent brazing, so one alternative is to permanently stick it in place with a quality 2-part epoxy resin type glue. Araldite springs to mind, but I'm unsure if it's available north of the 49th parallel, or even in the Western hemisphere.

I like that idea for the spark plug, Brad's idea of fastening the guide to the head by drilling through it and then countersinking a tiny screw should still let the valve pass through.

Perhaps, besides Morrini, the earlier or all Jaguar V12's were a Heron head...The the US, the 50's Lincoln "MEL" OHV V-8 and the Chevy 348-409 had Heron heads..

I think what killed Heron heads was the move to higher rpm engines. Herons are great for torque at mid-range, but everyone wants to be a racer now.

Herons are compact, easy to build, and give good fuel economy and torque, making them a great choice for the smallblock. I ride my "modern throwback" w pride.

Post by: Knuckle Dragger on March 22, 2019, 07:11:51 PM: My long-departed but still beloved Alfa Quattro/Giardinetta was Heron Headed. As was its predecessor (I think): a 2 litre Kent Cortina-powered Ford Escort. Still my favourite car of all time....

There's something about larger, powerful motors in small, lightweight cars. Both had lovely sharp Pininfarina lines about them too. Mix in a rear or all-wheel drivetrain and stir with gobs of opposite lock along a well-graded gravel road & magic happens....

Post by: canuck750 on March 22, 2019, 07:59:56 PM: That Guzzi complete drive line cutaway is very cool, beyond my ambition!

I cut open the other cylinder and head to expose the push rods and intake tract.

(http://i249.photobucket.com/albums/gg217/canuck750/Cutaway%20Motor/IMG_2563_zpslfzr74jq.jpg) (http://s249.photobucket.com/user/canuck750/media/Cutaway%20Motor/IMG_2563_zpslfzr74jq.jpg.html)

The next step is to cut open the cylinder block in line with the cylinder cuts I have made to expose a view of the cam, distributor drive, the lower end of the crank and wrapping around the oil pan to see the oil pick-up and strainer. Then I want top open up the front cover some so the gears will be visible and the outer cover to see the generator belt. I will probably attach the flywheel and clutch assembly and cut a pie shaped opening ion the assembly yo see the various parts. I may cut open a carb and the generator as well. Its going to be a work in progress thing.

I am learning how to better make use of my mill and band saw :evil:

Yes, they make good truck engines :grin: in the early 60's the Chevy 409 was the stuff of legends in stock drag racing...But out on the Nascar tracks the heavy pistons limited RPM and durability...

Title: Re: Now That's a Hemi! or how I cut apart a Guzzi motor
Post by: F-22 on March 24, 2019, 01:53:54 PM: Heron heads are neat for two valves. A single plug makes a very good burn, compared to the classic designs like the hemi head which benefit a lot from dual plugging (for two valve heads). Also, swapping out pistons for better performance or more optimal combustion chamber is a lot cheaper than swapping the head...

The Heron head of the early Jag V12 was a direct descendant of the Coventry Climax FW, which were both designed by Walter Hassan and Harry Mundy. A big problem with the Heron head is lack of turbulent charge motion within the cylinder, which can lead to poor fuel economy. This can also be a problem with hemi-head engines and is why hemis often have 2 spark plugs per cylinder (having 2 plugs compensates for slow flame front progression because of the lack of charge motion). Jaguar switched to the swirl-inducing May "Fireball" combustion chamber and got almost a 50% improvement in fuel economy.

Next to cut open the top of the crank case on the other side along the center of the push rods, open up the rear main bearing and see the back of the crank shaft, should be able to see a portion of the cam and the distributor drive as well.

Samuel Heron was a British aircraft engine designer that was responsible for improvements in radial air cooled engines during and after WW1...He is credited with the Heron head, named after him obviously ...Some some dispute that...

I am going to try drilling a hole in the plug and guide, epoxy a pin into the guide / plug and then drilling a hole in the casting to take the pin and then hot glue the whole lot together. Only tricky thing is getting the holes to line up between block and guide, haven't figures out how to get that right.

I would think the ring gear would be hardened. Cut off wheel for that. Assuming :rolleyes: the flywheel is cast, a band saw should go through it like butter. A file will tell you what to do.

but …… I do have a junker 5 speed so I think I will cut it open as well and join it up, then I do have a used Eldorado final drive, now if I only had a spare swing arm ……..

I want to cut apart the old generator and mount it with a fan belt then cut apart a starter motor as well, then take it all apart and paint out all the cut surfaces red, add gaskets and seals and put it all together, make a stand etc …. I am considering increasing the piston / ring clearances and shorten the valve springs so I could hand crank if off the transmission output, maybe add some LED lighting inside the crank case and transmission case. I think it would be cool if I could figure a way to create a flash in the cylinder when the distributor fires

PS - If anyone has a pair of old used clutch discs for cheap that I can fit to this project please send me a pm
Thanks
Jim

Post by: canuck750 on March 31, 2019, 05:42:43 PM: I cut open a little window in the block to view the base of the distributor gear

I replaced the one cylinder because it had three broken fins but this cylinder has an iron liner and the bore must have been for a bigger piston so this piston is loose

I had a Tonti crank in the motor but the pulley did not fit right, swapped in a spare Eldo crank

I wasn't happy with the clutch cuts I made so I redid the angles

Helical gears run quietly compared to spur or straight cut gears which make a load whining noise when they are running.

Compared to the later chain drive it doesn't have as much slack as the chain got and it doesn't have a chain tensioner to fail. Downside is that they are probably more expensive to make. They also create an axial thrust due to the angle of the helical cut gears. Spur gears and chains don't produce any significant sideload on the parts.

Also have an increased load rating over straight cut, some 30% I believe.

Post by: canuck750 on April 01, 2019, 08:57:54 PM: I scratched my head for a long time trying to figure out how to mount the guide to the head, I came up wit this, slit the guide down its length in the mill, drilled a hole and counter sunk it through the guide to take a M4 machine screw, flattened two side of the machine screw to fit the width of the slit

(https://i249.photobucket.com/albums/gg217/canuck750/Cutaway%20Motor/IMG_2685_zps2jepqk3z.jpg) (https://s249.photobucket.com/user/canuck750/media/Cutaway%20Motor/IMG_2685_zps2jepqk3z.jpg.html)

I marked the head with a centre punch and drilled and taped the head, screwed in the machine screw then filed down the head and staked the screw head to the brass guide

(http://i249.photobucket.com/albums/gg217/canuck750/Cutaway%20Motor/IMG_2686_zpsc9sqqng3.jpg) (http://s249.photobucket.com/user/canuck750/media/Cutaway%20Motor/IMG_2686_zpsc9sqqng3.jpg.html)

I shortened the springs to reduce the pressure on the guide

Then set the retainer collar and collets, done

Cut open the rust breather box, blasted it and painted it

I took the generator apart and cut away the body and front cover then put it all back together

I fitted a set of rings to the cutaway piston, looks like the rings of Saturn

(https://i249.photobucket.com/albums/gg217/canuck750/Cutaway%20Motor/IMG_2706_zpstvgwjhwh.jpg) (https://s249.photobucket.com/user/canuck750/media/Cutaway%20Motor/IMG_2706_zpstvgwjhwh.jpg.html)

I fitted some gaskets to see if I should cut them flush or leave then whole?

(http://i249.photobucket.com/albums/gg217/canuck750/Cutaway%20Motor/IMG_2710_zpsrq5nlfey.jpg) (http://s249.photobucket.com/user/canuck750/media/Cutaway%20Motor/IMG_2710_zpsrq5nlfey.jpg.html)

Thinking I may leave the whole gasket, I think it helps the mind fill in the missing parts and understand the form, what do you think??

That's just not good enough Jim. You will just have to scrap the whole project and start all over again. :evil:

Post by: canuck750 on April 04, 2019, 07:33:21 PM: I figured out a way to pin the spark plug to the head, I drilled a hole through the side of the plug then braised a brass rod to the hole in the plug. Drilled a deep hole in the head, filled it with JB weld and tapped the plug / pin into the hole.

(https://oi249.photobucket.com/albums/gg217/canuck750/Cutaway%20Motor/IMG_2850_zpsmixuovr2.jpg) (https://s249.photobucket.com/user/canuck750/media/Cutaway%20Motor/IMG_2850_zpsmixuovr2.jpg.html)

Its pretty solid, when the JB weld sets up it should be rigid

I bought some sign paint called 'One Shot' and started to paint out the cut faces to see how it will turn out

I clean the rough cuts with an autobody file, the old fashioned steel serrated blade that screws to a wood handle, a hand file and a mini air driven belt sander. then into the vapour balster

Test fitted to the engine

Now just to clean up the transmission internals and put it together then paint the cut edges. This small motorbike hydraulic lift table may just ne the perfect display stand, a couple C clamps around the bottom of the oil pan to the table secures it.

I am pleased with how it came together and I think I gained a better understanding of the Guzzi drive line architecture, damn solid piece of engineering.

Sure did, just this afternoon, Thanks for providing the last of the missing bits.

Thanks for the stand picture Rink Rat, that would be perfect, a great big industrial cast base, powder coat it and put a rotating type top on it! I need to keep my eyes open for that kind of thing.

Post by: canuck750 on April 18, 2019, 04:01:57 PM: I have had some 1/8" steel plates laser cut with the Guzzi text and logo, I traced over a jpeg in AutoCAD and sent the files to a fab shop.

These two sides will be joined with a 1" x 1" steel angle to a 1/8" steel base plate and I plan on making up an opaque white plexi-glass light box to fit between the steel plate sides and back light the logo and the underside of the engine.

Thanks Rick!

Yep it still rotates, I am guessing that the generator could become a motor? What it would really need is a very low rpm 120v electric motor inside the generator case to rotate the engine. I thought about attaching a wheel with a handle like one off a milling machine but much larger diameter to the transmission output shaft and then rotate the drive line by hand. I have lots of work to do just to finish the base and the lighting, our local vintage club has a show in a shopping mall the last week of May and I want to have it at the show.

Post by: canuck750 on May 02, 2019, 08:09:22 PM: I finished the engine stand today, laser cut 3/16" steel plate, 1/8 Plexiglas top and side inserts. I will install a LED light strip inside the light box and run it off a 12v battery.

If anyone wants the CAD or pdf file of the side plates for the stand just send me a pm with your email address and I will share the file with you.

No Roper sloppage plate fitted though. This could lead to a lube failure..... :wink:

Those appear to be V700 timing gears, which have finer teeth than later ones.

That is an interesting observation Antietam. I thought they appeared to be a different pitch to "normal" ones. I reassembled a set with similar pitch back into an 850 T motor, from where they came, and wondered what their heritage was. I am sure you are aware of the inability of a factory gear set being assembled into a chain motor due to the oil pump shaft end & centre distances being different. The crank gear was a shocking fit on the crank, I had to put a hardened washer behind it to work properly on the bearing thrust face, the cam gear was simply loose on the shaft & the oil pump gear needed a washer on the front so the nut would not threadbind. It has a billet high volume oil pump.
Here they are here;

Here's one I did in 1980 by hand with a hacksaw & file, in the lounge of a little flat I had with a Canadian chick. We split and she was surprised to see it finished when we got back together after a 20 year break. :grin:
It now stands in our front door entrance.

Post by: Groover on May 03, 2019, 06:02:17 AM: Great Job Canuck750, that is indeed a masterpiece. Sending you a PM also for that CAD file, thank you for offering it. You picked IMO the best version of the guzzi logo!
Title: Re: Now That's a Hemi! or how I cut apart a Guzzi motor
Post by: dguzzi on May 03, 2019, 08:23:01 AM: Our company would love to have one of our machines done like that, for a lobby display. But I'm sure they would freak out at the cost. Even just for the rotating part would be cool as heck.

Now the back half falls under the knife (well in this case a cut off wheel and sawsall). It's a leap of faith at this point...

I clean the rough cuts with an autobody file, the old fashioned steel serrated blade that screws to a wood handle, a hand file and a mini air driven belt sander. then into the vapour balster

Test fitted to the engine

Now just to clean up the transmission internals and put it together then paint the cut edges. This small motorbike hydraulic lift table may just ne the perfect display stand, a couple C clamps around the bottom of the oil pan to the table secures it.

Thanks mate, awesome stuff. Bloke here down under cut a section out of a 5 speed because he couldn’t get it to shift right...

I look forward to seeing your display base lit up. :bow:

That looks 'orribly like an Ajay/Matchy twin pushrod. :evil: Break it's crank did it? :rolleyes:

Sounds like we have some discussion time at the Tattley Rappet this year. :thumb:
Title: Re: Now That's a Hemi! or how I cut apart a Guzzi motor
Post by: Roy gardner on May 11, 2019, 03:50:37 PM: Correct Muzz. No, it didnt break that crank, just blew it's aluminium rod out and ventilated the case as they do. The crank that is in there is "twisted" around the centre main bearing according to the reconditioner who I asked to grind it. That appears to be a contradiction considering that cast iron is so brittle we dont generally imagine it having the ability to "twist" without breaking.
