- Ok so for those that hadnt realised, the last video was chopped short at 5 minutes - no idea why ? Here is the full 20 minutes. A few points of note explained along the way in getting the engine to sit in the brackets.
Regarding the universal joints/Hookes Joints, if the yokes aren't in the same plane they do not act as a constant velocity joint. Fitting them not in the same plane will induce wind up in the system leading to accelerated wear. Hope this helps. One Hookes joint alone is not constant velocity. Two cancel each other out and give constant velocity but only if the yokes are Co planar as mentioned. The video was brilliant mate.
well that explains a lot ! Cheers Carl' another fact to be stored away :-)
@@lookcreations No problem at all. Happy to help.
EXCELLENT explanation of the Prop Shaft alignment . I would have said muct the same .
@@johncunningham4820 Thanks much appreciated!
That engine looks great! Good to see it in, as you say - milestone reached 👍
Cheers Max' - next challenge is the turbo and exhaust pipe connection. First off I have to put the bits back on the turbo ... once I find them ;-)
I love the colour of the block
Brilliant, great milestone and great to have the whole story 😀
thanks - I really am rubbish at the video editor stuff
Well done Matt looking great
Looking good!
Regarding the propshaft yoke phasing, if the input and ouput are parallel with each other then the yokes want to be inline to avoid speed oscillations.
If the input and output are not parallel to each other, phasing one yoke 45° from the other reduces the speed variation compared to the yokes being inline. This is a common trick on truck chassis PTO drives, the engines point down towards the rear axle say 4° but the PTO connection is parallel to the chassis, a 4° overall difference. However, they often have several propshafts to get to the back around parts of the chassis with some joints at say 10°, this is where the yokes phased 45° from each other comes in to play to reduce the speed oscillation. Discovery 1 front propshafts are phased 45° too.
Propshaft vibrations on something like a Series is generally the prop (or another part of the driveline) is worn out as theres so many bearings and shafts to keep maintained.
That’s interesting and additional information, thanks.
Great progress!👏
Thank you!
NICELY DONE
Gday Mat, it’s all coming together now mate, looks bloody good to, cheers
It looks better than when I started ! Still a long way to go though. Thanks for sticking with me. Mat
Found this on Google.
Explaing the importance of UJ Phasing ..
"The Concept and Importance of Universal Joint Phasing and Drive Shaft Alignment
Phasing is the process of aligning the universal joint yokes on both ends of the drive shaft (or double u-joint) in a parallel fashion. If the joints are not properly phased, they will operate at varying speeds throughout each revolution which can cause second-order vibrations. U joint vibrations can lead to increased wear and potential damage to the assembly and failure of the application".
I’m getting my head around the issue of varying speed within each rotation, increasing vibration etc I dare say some clever chap could do the maths and graph the harmonics involved. The thread I read was on a defender 90 where the owner had installed aftermarket prop shaft on the rear and was having vibration issues, claiming the dynamic balance was out. Photos showed the yokes out 90 degrees. Hard to know if the owner had stripped and rebuilt the shafts misaligned or they had been sent out - or if the balance was out due to being balanced out of alignment. On a series, I’m not sure you’d notice balance unless it was way off 😬
@@lookcreations I've seen this happen before, where the yokes have been misaligned. You don't get a constant velocity output and it can cause a lot of issues. My background is aerospace. If you get vibrations or out of phase velocity variations in that field you are really in trouble. In any event, the vibration and velocity mismatch will cause noticeable noise and increased wear in the bearings of the joints.
There is a fair bit of complex geometry involved in explaining why a single uj is not constant velocity. Basically, depending on the input angle, the output speed of the drive will vary in amplitude and wavelength around the 360 degree rotation, by varying amounts. The greater the angle of the joint, the more extreme are the variations. So if we have two joints connected together, and they are correctly phased, the variations in velocity throughout the 360 degrees cancel each other out. We still don't get a true constant velocity, but the variations are reduced to a minimum. Conversely, if the phasing is not correct, the variations will add and aid each other in various ways that can only lead to disaster.

I found out the hard way.
In my teens (Triumph Herald days)
I went on holiday with the "to be" inlaws and a UJ died in South Wales.
I did an on my back under the car replacement an did it wrong.
Had to do it all again when we got home.
The vibrations would shake your teeth out.
@@stevewilliams2498 That is a really good example. The one I remember from my education was a massive steam powered crane made by Stothert and Pitt. It had wheels and ran on rails, it was assembled in South America in the 20s. The ujs in the shafts to the rail wheels were phased wrong. On its first run out it completely destroyed the rails it was running on. If the joints are not phased right, their life can be measured in hours.
Very nice progress indeed. The whole kit is looking great together. I'd have a couple pints and sit in the chassis making motoring noises driving about.
With the luck I have, I’d get pulled over and a ticket for speeding and drunk in charge 🙄
First to comment for once. Brilliant video Mat, great to see things moving along.
Thanks 👍cheers Carl. Bit fresh down this way this week after a few days up at Kelso Salmon spotting. Hopefully I should finish fitting the peripherals this week in between chores and you now work etc.
@@lookcreations Hope you had a good time Kelso way. Its cold up here just now, very clear skies which is beautiful as we have had some really spectacular views of the Northern Lights recently. I know what you mean re time, I've had a lot of work commitment recently. Looking forward to seeing future progress on Clanger. Great to see you firing on all cylinders after your bout of illness. Take care mate.
Regarding the prop shaft alignment , on a defender , the front propshaft cv joint should 100% NOT be in line . I'm not sure if it's different for a series truck though . It has something to do with the transfer box and diff flange not being in the same axis .The manual refers to them as non constant velocity joints
Now that’s interesting. I will do some more research on the series 3.
Good work Mat, and doesn't she look good!!
Phil
cheers Phil
Nice Job. The clutch Press , what did you use ? from Defender or serie?
I’m trying to remember?. I think it was the series…. Not much difference between a S3 and the unit on the engine from what I recall
great progress. Are you watching Maximus Ironthumper ? he's rebuilding one also. Very entertaining.
I am yes, both Max and I have agreed to try and get together when Kermit and Clanger are on the road - might make for a fun feature !
Interesting about the props, I've heard the opposite in that the two yokes should be 90 degrees out of phase as you've got set up.
That is not correct. The two yokes must be in the same plane geometrically to achieve constant velocity from two Hookes Joints.
Take a look at the comment from Steve Williams about google search results
@@lookcreations I stand corrected then. Been a while since I did anything with a prop shaft with UJ's on. Might explain some of the vibration I used to suffer in my old Spitfire.
By next year you will be overlanding to Australia 🇦🇺
Kit from Down Under
murderous wildlife aside - I would dearly love to drive around australia - then Tas' & NZ ; its a wish list bucket list thing that is unlikely to ever materialise the way finances go. Might have to geta lottery ticket - aint going to win if I dont buy one :-) All the best Mat
I wonder have you ever read the book "Earth, My Friend" by Group Captain Peter Townshend. It tells the gripping story of how he drove around the world in a series land-rover in the mid 1950s. Its a great read.
@@carlwilson1772 I will have a look for a copy to read.
@@lookcreations I can send you mine if you like. I read it many years ago, have reread since. It's no trouble to loan it to you long term.
@@carlwilson1772 that is kind of you Carl, not sure I can say when I’d sit n read it through
