Thanks for the reply. If you are not familiar with it the sludge trap is a removable tube in crank pins. The idea was that as the oil circulated through the crank to the drillings for the rod bearings the centrifugal force would separate the oil from the sludge and deposit it there. Actually not a bad idea because these bikes had no real oil filter. Only problem is the tube eventually fills up and can block the oil path to the main bearings, so needs cleaned out during a rebuild. I would highly recommend you get the book "Building Budget Brits" by Mike Brown. Its usually available in paper back on Amazon for around 25 bucks. I can almost gaurantee the info in it will save you the cost of the book many times over. There are also some DVDS out showing how to rebuild a Triumph unit engine. One is by Wes at 4 Aces and is available from Low Brow customs. The other is by Hughie Hancox and I think Waldridges carry it. One thing about the T140e's is they have the Mark II carbs instead of the more common Mark Is. You do need to make sure when ordering parts to specify for the Mark II's because the earlier 78's had the Mark I's and many of the parts are similar but not interchangable. Also, Champion N5's are the correct plug for this bike although a lot of people will try to tell you the N3 is.
My bike came painted a solid reddish orange. I added the white panel below the badges and the rubber knee pads in kind of a mid 60's paint scheme. I really like the correct black tank with red flashes that the 78 had. If I had the bucks I would have mine redone in that. I have had mine for about six years and I ride it at least every week. Here's a better pic. Its all stock except for SS brake hoses, the paint scheme and Suzuki turn signals.

Also a pic of the Commando I am finishing up. It's a 72 750.

While I'm thinking about it there are a couple of special tools you need to strip the engine.
One is a clutch hub puller and the other is a pinion crankshaft gear puller. Most of the suppliers have them and not using them can do some serious damage to your parts. You can probably rig up something to pull the cam gears or you might try leaving them in place.
If the cams are in good shape you won't need to bother them.
When doing the reassemble you need the point seal tool.

There are lots of opinions on break-in oil. Do a search and you will get the idea.
Triumph recommend a #150 grit hone.#180 is OK,maybe #220.
Avoid synthetic oils for bedding in.Avoid oils with high detergent/dispersant.They can cause cylinder glazing if the engine is not loaded enough (if you baby the engine).Diesel oils usually have high detergent.

I've just ordered the book from Amazon for $17 and the Wes White DVD on Low Brow. I think actually seeing things being done will be a big help for someone like me who's never really done a lot of this before.
I've seen the oil filter you talked about earlier on ebay for about $80. It looks like you could probably make your own with the stock cover maybe?
I'll just pick up the tools as I need them. Everything is getting to cost too much right now.
I had the cylinders done to +020 already. Not sure what grit was used. I'll use this thread as a reference for the oils whenever I get that far.
Are the side covers on the t140e similar to the t140vů.or are they completely different? I see pictures I googled on the same year bike with covers like yours with a one line name plate.
Then others with a 2 line name plate like the 1979 has.
The Commandos look really good. My brothers looked somewhat different. I think because he added an oversized tanků.plus it was black.
I'll have to send him this thread so he can check it out.

check out Plewsy's videos on youtube, under LUNMAD. His bike is a 72? but close enough for most things.

If you want side panels, you can go "classic" and have fake per-OIF ones, or stay as you are, or have the secondary ones like on my E - but my E has Mk11 carbs and has different panels to Mk1's. The Jubilee had similar panels that might fit if you want the look.

Filterwise, most people go for a Norton type spin on hidden under the gearbox/rear wheel kits are available.

I think either of the t140e covers, one line or two will fit. The earlier t140v curved type or the fake pre OIF won't fit with the parallel carbs. I would not get the type of oil filter that fits up into the sump but would use a type that goes into the return line such as the MAP cycle type or the Norton type. Pete R is right on grit to use on a Triumph. Hats off to him for all the good advice he posts on this forum. He's saved me more than once.

I went and ordered the Norton type filter and the pistons I needed. I read a thread on the site here on how everyone was mounting the filter. There were a few places and ideas on how to do it.
I subscribed to LUNMAD's youtube site and watched a few vids already. He does a good job explaining things on the ones i watched.
So I have enough info and everything to get started anyway. Just need to find the time to do it now.
