Norton Atlas Project - Shep - Part 36 - Engine Disassembly - Part 15 Conrods & Sludge Trap
HTML-код

- Took advantage of a cold and snowy Sunday and spent some time in the garage splitting the crank assembly. Seeing what’s inside the sludge trap made the whole disassembly worthwhile. The cheeks came off without too much trouble and revealed a LOT of sludge in the trap.

• Norton Atlas Project -...
I’m so pleased that I decided to completely disassemble the motor.
A new crankshaft nut and bolt and new forged con rod bolts will be ordered for the reassembly process.

Helllo Mi Ty, we both are rebuilding a Norton at about the same time, I might be a month or so a head of you with the progress. I wish I could have watched yours first so I knew what I was in for. It is fun project and I can't wait to hear it run, hopefully this spring. Cheers Bruce.
Hi Bruce, thanks for your note. Yes, my friend told me about your channel this weekend. I've subscribed and will definitely take a look at your projects! Best wishes, Mike
Hi Mi, still watching your strip down videos with great interest, I was smiling to myself on your comment 'the centre of the earth' those first particles of sludge were formed some 30000 miles or so ago on its journeys across america!!!
Haha, thanks Ian! Yes, I understand the bike had been ridden all over the Country! It's a lot of fun seeing what lies beneath! Cheers, Mike.
Thanks for the vid. I am about to dis-assemble the engine of a 1968 Triumph 650 due to low oil pressure and I am dreading what I will find in the sludge trap. This bike was modified back in 1970 or there about into a chopper with extended forks and funnily enough it is named The Sludge Trap.
Ha! Thanks for sharing Matthew. Good luck with your project. Cheers Mike.
I've cleaned sludge out of many engines, don't remember ever having that much, any idea how many miles/years of buildup? I've never seen a Norton apart before. That's rather interesting crank assembly, thanks for showing this!
Thanks a lot, John. I appreciate it. I'm not entirely sure of the mileage, but I know it was a lot! The owner's brother shared that he had ridden it all over the country including a trip from Mexico to Alaska I believe!
Awesome!
Thanks a lot! I was just looking at your Channel. Really cool. I love your Bonneville project. Cheers, Mike.
Mi Ty Thank You!
First, before you dismantle a crank, is to mark the timing side, so you can reassemble it correctly. Otherwise you don´t know, which side was ..... and you have to rebalance it.
Thanks Martin, yes, I punched marks on the cheeks but didn't capture that I guess. Best wishes, Mike
Wow that was some crud, crank looks in good nick. Nice to see Bruce is here with us Now! is he far away from you Mike.
Thanks Keith. I'm not sure where Bruce lives. I've only watched a little bit of one of his videos so far but I think I detect a Canadian accent ;)
Mike frankly speaking i got that timing wheel support pltee only after i saw you dismantling this video I have a norton model 88 to restore & you can beleive how education this video of yours is for a layman especially as me- by the way I had to ask you mike- those whitworth sockets you are using- is which MAKE- ??? do let me know some information in the tools you use- keep up the great work mate- Cheers & kind regards from india- Rahul
Hi Rahul, thank you for your kind words. The BSW (British Standard Whitworth) sockets are by a British Company called King Dick. But you should be able to find similar BSW sockets, perhaps from another supplier. I find them very helpful and use them a lot more than spanners/wrenches. Best wishes, Mike
Older video but has me interested in how these go together.
One of these days, I will get back to this project Wooley!
Not done yet? Maybe I need to keep prodding you to get her done.
Hehe, yes, one of these days!
Is there any old Brit bikes that do not have a sludge trap? I have cleaned a few but sold all the bikes. Now I'm getting the bug again, and it's the dreaded ritual of cleaning these that I'd like to not do.
Martin Cvitkovich Hi Martin. I’m not aware of any Brit bikes that don’t have some kind of sludge trap. Possibly there are some makes. Yes, I’m afraid it’s one of those joys of Brit bike ownership! Best wishes.
Do you always clean parts with WD40 instead of a solvent tank?🤔
Thanks fw1421. I mostly use WD-40 for cleaning cycle parts and just to give a general clean. But will use a solvent tank for the crank assembly before reassembling. My friend has a friend who has an industrial solvent parts washer that we are hoping to use. Cheers, Mike
Hey Mike! This is an awesome build/restore that you're doing. Very informative, thank you. Have you decided how you're going to be refinishing the case, cylinder, cyl head and etc yet?
Hi Stephen, thanks a lot for your comments. I haven't decided yet about the finish. I've had other engines vapor blasted and they look beautiful, but I'm going for more of an original look with this bike. Plus, it's difficult knowing where to stop once everything starts looking new again ;) I'll probably spray paint the barrel or may have it powder coated but again want to keep everything looking consistent. For the head, I think it will most likely be a good professional cleaning, maybe vapor blasted.. I'm still undecided! Cheers, Mike.
Has anyone offered a compelling reason why there is such a thing as a sludge trap? is there no other way to deal with a build up of coagulated oil? Would a fully synthetic oil do that or only mineral oils?
all these engine rebuild's you do ,how do you find time to push those piece's of paper about.
Neale Bradford haha. I know! Work is getting in the way of my enjoyment these days 😉
there is just something about revealing and cleaning out a dirty ole sludge trap...
Haha, you are so right!! It makes it all worthwhile ;) I think I would be pretty disappointed if the sludge trap was spotless after all that work ;) Best wishes, Mike
That's some Nasty shit. Why do all Brit bikes have sludge trap's ? Enjoy your video's .
Thank you Steve. Yes, seeing that sludge in there made all the dismantling worthwhile. The sludge trap (or sludge tube) were intentionally designed to capture / filter out deposits & other debris - via centrifugal force - from reaching the connecting rod journals and bearings through the crankshaft. It was a modern design at the time ;)
ps, only joking.
Too tight so stretched.
That was a truly dreadful engine. It didn't last long either on the road or in the marketplace. It arrived because Norton could think of nothing better than boring out their parallel twin to keep up with Japan. Look who won.
This has been helpful, I am working on a '66 N15CS. Mine is thankfully not as sludgy, just 2 deposits of about 1/4" of the stuff 180 degrees apart, curious if that's a balance thing. At ruclips.net/video/4r2CVzzLaJc/видео.html you really are leaning into that conrod nut, I was cringing a bit to be honest. I use a foot long iron plumbing pipe over the end of the ratchet or a breaker bar, Archimedes would approve. I am nowhere near where you are knowledge-wise so don't take this wrong, I just hate to donate to the knuckle meat god.
