1976 TR6 - Part 10 - Degreeing The Camshaft

[@timmarsh6754]

Great to have you get to the bottom of how the variation works. I, like you, thought the holes were non-perpendicular, but your new explanation makes perfect sense. Thank you.

[@boatboattmmrp9950]

This is one of those subjects that shouldn’t be hard to understand, but the problem is most other videos out there assume you have a cam card and timing marks. They never actually show you how to degree a cam with math. Your videos were a huge help and really simplified the process and gave me piece of mind.

Your work is SO helpful to me in my restoration of my 3B. Thank you, thank you! Have a merry merry Christmas with your family and a Happy New Year!

[@PeterStickley]

Many thanks for the explanation at the end - makes perfect sense now.

Elin, another great video and the best one yet on Timing. Not an easy subject in some ways ! Thanks for all of your work

[@chrisdaley2200]

Merry Christmas Elin!

[@MrDazvere]

Another great video Elin. Very informative and very well narrated. Merry Christmas to you and your loved ones and a Happy and prosperous New Year!

[@MikeAarset]

I actually really enjoy doing cam timing. I put a race cam in my A-Series 948 bugeye engine. Went through all the steps timing the cam to piston one. Had to use a offset woodruff key to get the timing correct. It was such a joy a couple days ago to start up this engine on my garage floor and it actually started and revved up cleanly.

Very nice tutorial on timing,enjoyed it.just continue on with what you’re doing and on to the next video.be safe 😎😎😎👍👍👍

[@andrewdonald4046]

Thanks for producing these videos Elin. I really enjoyed this timing one. Have a merry Xmas and a great new year.

[@edwardkendall3905]

Love it, nice explanation.

[@alanm.4298]

Good explanations, Elin! Your new and improved degree wheel should help avoid those accidental BDC timing errors! 😊 I never understood why they didn't simply make the duplex cam gear symmetrical from side to side, to allow the 1/4 tooth adjustment with it, too. Maybe they just figured 1/2 tooth was "good enough". FYI, adjustable (vernier) cam gears are available for both the 6-cylinder (TR6, GT6, etc.) and 4-cylinder (TR2 - TR4A) engines. They are a duplex design, accommodating the double row chains. Of course, the adjustable gears are considerably more expensive than the non-adjustable... $165-$170 versus $43-$45 at BP Northwest. Unfortunately, BPNW doesn't offer for Spitfire. However, Rimmer Bros. offers kits including an adjustable cam gear, duplex chain, and crankshaft gear for Spitfire as well (one kit for Mk 1, 2, 3... another for Mk 4 & 1500). Rimmer also offers similar kits for the 6-cyl. and big 4-cyl. engines.

Elin Awesome video! If you eve have enough time get an Alfa Romeo twin cam 4 cylinder engine up to 1995. Each cam is infinitely and independently adjustable at the timing chain sprocket. When setting the timing those engines you can adjust the cams and control when they begin to open & close the valves and control valve overlap as well as scavenging in relation to crank angle. The theory is crazy interesting. All this in a regular production car too. Nuts.

Merry Christmas and a happy New Year to everyone. Another well explained tutorial on an essential skill. Lending tools that never come back, what's the saying, " never a lender or borrower be?"

[@RustyBeauties]

oh, no, this one is coming back. I lent it to a fiend :)

[@kge420]

Not sure why but this is one of my favorite things to watch. @2:30 would that be Dave that borrowed it? Merry Christmas to you and your family.

[@RustyBeauties]

@@kge420 haha, he would use it to grade cheese in his soup.

[@RustyBeauties]

@@kge420 Merry Christmas and all the best to you and Mary as well!

[@BruceBoschek]

First, I guess. 🙂 Looking forward to watching this, as always. Thanks Elin!

[@davidwarr8600]

Another very informative video. After watching your video I am amazed that I ever got the timing right on my GT6 40 years ago when I changed the timing gears and chain. Maybe I didn’t but it still runs well. I was a little worried when I saw you take off the degree wheel and bend the pointer. Why didn’t you loop the chain over the sprocket before you did the alignment?

[@philhunt4070]

Great explanation on how 1/4 tooth is achieved on TR4 but why can't the remanufactured sprockets be made like the originals? Thanks Phil

[@RustyBeauties]

Hey Phil, some of them are made the right way, but some of them are not unfortunately. I am assuming that some of the re-manufacturers are not really aware of the rule that the axis needs to be 1.07° offset from the tooth and they just align it with its tip, which leads to losing the ability achieve the 1/4 tooth adjustment

Happy Holidays Zoom zoom 😊😅

[@MrMikeyspfx]

Thanks Elin your videos never fail to teach us, just curious as to what model tr is on the tv behind you,it looks like a combination of a 3 and 4. Maybe AI ?

[@davidsnipes7297]

Interesting. Those old designers and engineers were amazing. Say, that TR on the screen behind you is making my head spin. The turn signals and running lights and fender shape and grill are like messing with what I thought I knew about the front end of a TR4… or am I missing something? Help me understand that please… well done!

[@RustyBeauties]

@@davidsnipes7297 😂 that is an AI design. I asked it last year to put a rusty TR6 actually in front of a Christmas decoration and this is what it came up with 😆

[@davidsnipes7297]

@ AI is not to be trusted! LOL.

[@barry6274]

Thanks again for a wonderful explanation of this tricky but interesting subject

[@thomasweiss3326]

Just buy one there cheap
