Norton Atlas Project - Shep - Part 30 - Engine Disassembly - Part 11 Timing Case
Вставка
- Опубліковано 10 жов 2024
- Finally getting around to disassembling the engine starting with the timing case / chest.
Crankshaft Oil pump worm gear nut (left-hand thread)
Camshaft pinion / drive sprocket nut with slot for the tachometer drive / rev counter
Cam chain tensioner and backing plates
Magneto Auto Advance Unit
Cam chain with camshaft pinion & intermediate pinion assembly
Thrust washer from behind the intermediate gear
1/2 time pinion
Woodruff keys on crankshaft 1/2 time pinion & camshaft pinion / drive sprocket
Triangular washer / back plate for the crankshaft 1/2 time pinion
Cup sealing washer behind the triangular washer
Everything went very smoothly with no big surprises. The only adjustment required was to grind parts of the the ears off the 1/2 time pinion puller tool so that it could fit into the recess and behind the gear.
Next video will cover the removal of the Lucas K2F Magneto.

I'd also like to thank Mick Hemmings and the NOC for their great video/DVD. I found this to be very helpful as part of my rebuild.
The DVD "HEAVYWEIGHT TWIN REBUILD" was produced by the Norton Owners Club (NOC) with Mick Hemmings and can be found on the NOC website.

I'm impressed how clean it looks inside that case. I hope it's that clean inside the crankcase.
Me too Scott. I'm hoping it will be as good on the inside. Cheers, Mike
Greetings ! I have to tell you how much I am enjoying these vids of yours. I do not have a Norton but I am riding other various Brit bikes and your manner and detail are very enjoyable to watch. We met at the rally in Missoula and shared a chat and a ride or two with you on your single an I was on one of the twins.. Keep em coming ! Cheers
Thanks a lot Ducdude! Really appreciate your kind comments. You may have seen this series from the Rally. Wasn't it fantastic! I also have a twin now so hopefully will be able to keep up with the rest of the pack in the future. Best wishes, Mike

I have seen the rally vids and it was indeed a hoot!. I do not recall you having issues keeping up with the Comet as long as the speeds were under 70mph :-) Remember if you have a twin that twice as much to go wrong:-)
D Ducdude Eric! The penny just dropped and I just realized who you are after connecting the dots via an article I just read below. 😜
I’ve been racking my brain trying to figure out who you were. Yes of course I remember you and some fun rides and conversations. Cheers, Mike

A breaker bar is a great tool to have if you need to apply a lot of torque safely with less chance of damaging nuts, threads etc.
Good day. You might end up being my new best friend. Just thought I’d let you know that upfront I just picked up a 66 Norton atlas it’s 90% restored from what I understand. The previous owner did nothing but did mention that the magneto was flopping around, so he tightened it up, is it possible for that magneto to be loose without the auto advance being taken off first. Thank you I’m Johnnny from the great white mountains in New Hampshire United States.
Great update Mike, I loved your close up shots. The engine seems to be in very good nick so far (ok, one bore is a bit messed up with all the water damage) and I reckon/hope you will be able to get away with new shells, new mains and a sludge trap clean once you get the crank out :)
Thank you Bob! I'm happy to finally get moving on it. Yes, I'm hopeful that it looks okay inside.. so far so good ;) Best wishes, Mike
Hi I am currently restoring a 1961 Dommie following a similar series of videos to yours I posted for a Honda 400 4. There is so much support for the Honda and was intimidated my the Norton. Anyway inspired by your video series I am ready to tackle my engine which appears pretty similar to the Atlas. Really like your calm voice too very reassuring.
Thanks a lot for your very kind words! Please let me know if I can help. You may already know of them but I can also recommend some Norton-related organizations where you can find lots of great advice if needed. I've also just subscribed to your channel to follow along ;)
Best wishes with your excellent project bike, Cheers, Mike.
Maaaate! A life of busted knuckles, stripped threads and sheared off bolts and studs taught me my two best friends when stripping an engine are a three foot length of steel pipe and a $5 butane torch that uses $2 aerosol cans of gas. A bit of heat (not glowing hot) and the pipe slid over the end of your ratchet drive and tick! They come apart easy-peasy using the basic physics of heat expansion and leverage. More heat required for bolts/studs frozen in alloy. Heat up, wd-40, walk away. Do this over a couple of days and you won't be drilling out bolts and studs from alloy components. Your knuckles will love you and so will your wallet. Great vid, l need to strip the timing gear out of my P11 engine that has not run since last century and now l know where the left handed threads are. Interestingly mine has a distributor and the pinion is held on by a roll pin only. Cheers from Oz.
Many thanks Luke!
@@TheMightyGarage Discarded fork legs make an excellent pipe, use a solid drive so that you don't ruin your ratchet drive ( solid drives usually just have a bar, no rubber handle, so pipe goes over easier. If you bend the bar, turn it 180° next time and straighten it. I also try to buy six sided sockets, not twelve, that saves ruining a bolt head or nut. Cheers.
@@coolhand1964 Thanks again Luke for your advice. I appreciate it. Cheers, Mike
@@coolhand1964 Yes I agree. A breaker bar would be nicer than stressing the rachet driver. And 6 point sockets. If there is room the heavier weight impact sockets are sometimes best.
Struggling to find TDC + set timing on my Dominator... did you create a video for that chapter on this Atlas rebuild? Thank you!! 🙏🏼
Hi Isaak, even without a timing disc, you can set TDC with just a pencil placed down the spark plug hole. Just be careful not to drop it! If you carefully hold the pencil against the threads of the spark plug hole and gently turn the wheel, you will feel the piston rise and fall against the end of the pencil. As the piston comes up and raises the pencil, you will feel the piston stop and pause for a moment before dropping down again. That would be a good rough estimate of TDC. I didn't do a video of the Atlas timing yet but I do have one on setting the timing on the Vincent. It should be a very similar process. Best wishes, Mike
That was tight, if in don't give it a clout with a Big Hammer! I think I try heating it up with blow torch before the clouting starts.
Hi my dad as a 650 twin cylinder Norton dominator it starts up and only seems to run on left cylinder,but if you disconnect the left plug lead it then runs on the right cylinder any help would be appreciated
I really love watching your vids, because I am trying to revive my late Dad´s 650, but it makes me cringe when you bash the ratchet with a hammer or put drill chucks on a thread.
