Finally got the sludge trap plug out. This was an SOB to get out. It took 10 minutes with the BFH and the impact to turn it 360°. Another 5 or so to get the next 360° and then I put the  1/2" air impact to get it the rest of the way. Plug is pretty beat up from previous work. I'm surprised this bike had so much work done before my brother bought it 2 years old in 72. The plug looks as though the "stake" was drilled out with a too large bit, but in the plug, that is being replaced, and not the wheels. I don't know why this plug needs to be staked when it is so freaking tight going in it needs serious impact tools to remove. The replacement plug is an allen and not a slot.








A simple external oil filter installed at the factory would have prevented having to tear down an engine to service the trap.  My 71 BSA is exactly the same.  My 1966 305 Superhawk has a centrifugal separator and no actual filter, but is easy to access and clean.

It's under that big plug in the end of the crank weight, inside the crank pin. Oil is pressurized through the crank and out the journal holes to oil the rods. The sludge trap catches the sludge as it spins around and contains it in the tube. Look at the pics in the previous post you can see where i removed the plug from the end of the crank, the tube sits in that hole and is 1/4 filled with sludge. I haven't been able to remove the tube yet, it's stuck and the "J" hook method wasn't working to remove it so I will need to buy a 12mm tap and thread it in to grab and pull out the tube.


Go here and look at page 12, it's part #3 in the diagram. I you have a Triumph you really should have a factory part manual and workshop repair manual. This link can dereferenced if you don't have a hard copy of them.

I see, so it is maintenance but only when the motor is taken apart. Is there a service manual link too?  Thank you for the link, I'll download and save...Larry

Powderman,
Do the older British bikes also have Whitworth threads as they do with special wrench sizes or BSC standard threads ?
I'm not trying to quiz you,I just never have gone that deep to find out..

What do you mean by "older"? By 1970 they had pretty much converted to all standard sizes. If you want to learn more about Triumphs for yourself join Triumphrat.net.

Here's a little read about the threads and bolt sizes. Triumph went through a whole array of different sizing on thread pitch through the years.

Google "When did Triumph convert to standard threads?" and it will bring up all kinds of info on the subject.
 Stuart and Johntioc are, in my opinion, experts on all that is Triumph at Triumphrat.net.

The "tioc" in Johntioc stands for Triumph International Owners Club of which he heads and he is very forthcoming on anything you want to know. I believe John is also part owner of the The Bonneville Shop.

I was contemplating a Wrinkle or Matte finish on the cases, but going through my stock I found some Raven Texture Black and decided to go with it on the cases and then the smooth Matte Black on the covers and bits bolted to the motor. They came out exactly how I wanted.






Waiting on the main bearing and the sludge plug to arrive and the reassembly starts.

Once the covers are coated black I will replace the alloy Patent tag that is completely stripped aluminum right now, with a aesthetically matching brass one to go with the rest of the black and gold scheme.

I had another 650 primary cover that I have no idea where or when I got it  and had coated it a few years ago in wrinkle black. I kinda like that look too. So I will coat the one off the bike in the Matte and then decide which way I will go. The only downside right now to the wrinkle is it is too gray and not as black as the Raven Texture.

I see the late model Triumph did something similar with the "Bonneville Black" model. Now I'm looking at my freshly blasted head/rocker boxes and thinking of coating them and sanding the fins edges.

Sludge plug arrived today from across the pond and got it installed. Waiting on a main bearing and HondaBond to show up , hopefully tomorrow, to begin the reassembly.





The allen plug is much easier to deal with than the stock slotted plug that is very tight to get in and out.
I find staking and LocTiteing this plug to be totally redundant. It took a 2lb sledge and an impact and 10 minutes to turn it out one revolution. There's no beating the positive action of an allen.

Though I think it totally unnecessary, I did put a small stake in it.  As I mention it was a major ordeal getting this plug out and I expected it after watching the Lunmad youtube video, with lots of torch it even took him as long as I to get that plug out. There's no way one of them is ever backing out on its own. I used a liberal amount of Blue LocTite because it needs to hold oil pressure.





I noticed the new plug had thread edges like razor blades compared to the old plug that had very dull edges. The new plug went in about one turn before it started to shave the sharp edge off in one piece as I drove it home, had a 20" long spiral wire when I was done. There's no gap between these threads in that hole for sure.

My HondaBond  showed up today, but still twiddling my thumbs waiting on a main bearing from across the pond. Then it's down hill on the rebuild.

What did you decide on a rotor carrier for the rear?

Wow, your ears must have been burning, not 10 minutes ago I was thinking I need to get with you about the carrier. I will need a custom bearing carrier that coincides with the rotor. I need the rotor carrier specs before I can come up with the bearing carrier specs. I'll PM you.

this build keeps trying to bite me in the are every time I turn around. Bad enough I lost am original bearing carrier when sent to China. Last night I package up a Kimtab rotor carrier and the Triumph Daytona 675 rear rotor to have a custom rotor carrier made by a member here. I package it up in a flat rate envelope and go to put it in the mailbox, it won't fit. So I figure I'll just put in in a plastic grocery bag and hang it from the mailbox with the flag up for pick up first thing in the morning. For safety purposes I didn't hang it on the box till around 3am on my way to bed. I haven't gotten much sleep n the last 2 weeks because I am nursing a nasty lingering cold and can't go more than minute without coughing, so no sleep. I crawl out of bed at around 8:30am and go check on the package through the window. I see the bag hanging, but it looks as though it is empty and blowing in the breeze so I go out and check on it and the bottom is torn open and my package is gone. WTF, not again. I immediately know it was going to be the work of my neighbors dog and I start heading that way and lo and behold there is my package laying their front yard with the corner chewed open, but no parts missing. I retape it, rehang it on the box and wait for the mail lady to show at around 11 to ensure it gets off safely.
 All was not lost because when she arrived she was bearing gifts, bearing bearing gifts, as she handed me the main bearing I need to proceed with reassembling the cases. So I will be busy to day for a bit.

 You saved those parts from your neighbors dog 'crusher'   ::), it's also a good thing the parts didn't have the smell of hamburger meat  ::) I hope you get more sleep dude.
