ive restored many triumphs and have done one of these 71 tooc models - I did mine about ten years ago and at that time I wasn't doing the motors myself -so I took the motor to our local ace and crook here in Rochester ny, this was a mistake- but I profited by my mistake it forced me to learn how to do these motors, I bought a tape by Hughie hancox step by step , he worked for the triumph factory from 1954 till it closed, , his tapes are for 650cc's but give you a general idea of the triumph motor, there are also service manuals available for the 500's, - if you have matching #s the bike is more valuable. and I would not go too far off from correct when you do this bike or you will be wasting money, first off I would buy a camera that can be down loaded to your pc , so you will have a good reference pictures , this project could take a year or better.
you already have a lot of info via the site but i'll throw my opinion in too don't waste your time trying to start this thing ,it turns over that's all you need to know, at the heart of this engine is a thing they call a sludge trap if that trap is full of sludge its a time bomb ready to blow- triumphs didn't have oil filters and they used non detergent oil so sludge was collected on the walls of the crank case and the sludge trap this worked well if youd didn't get smart and put the newer detergent oils of today in them what happened then was the detergent oil would wash the inside of the crank case and plug the trap stoping the oil flow ti the big end bearings , that's why you see old triumphs with holes in the front of the crankcase where the rods went thru. triumphs have a screen in the oil tank where the oil goes out the bottom and to the oil pump, its then pumped into the timing cover which directs it to the crankit goes into the sludgetrap before it goes to the rod bottoms at that point the oil floats the crank and bleeds the excess from the rods onto the crank to be flug all over the inside of the crankcase forming a mist and lubeing everything inside the case , and forming a pudle at the bottom of the crankcase to be sumped back to the oil tank and some goes to the rockers too the sump has a screen on it also, theres realy no place to attach a oil filter such as is on your car and needs lots a pressure . I have bought several cranks when I see a good deal on them ,the journals miked fine when I open the trap its usually full or almost full, scary huh I allways tear a engine completely down unless I trust the previous owner when he says he did the trap , a while back a guy had a bike on ebay I was interested in he stated that he rebuilt it so I casually asked him what about the sludge trap his reply was whats that, I lost interest at that point. when the crank is free from the cases you will see a plug in the crank with a slot in it for removing it, allways heat the area surrounding that plug before attempting to remove it, the factory usually used a punch to pene the last thread over. its like a lock nut thing. use a small drill to clean the pene out and it will still come out hard later sludg trap plugs had a elen head insert, after the plugs out there is a crank bolt on the flywheel that holds the trap in loose it, I made a easyout like tool to tale th tube out, service manuals also detail this procedure,--I do my own wiring theres no sense in me buying a standard lucas type harness when I gotta m,odify it for my electronic ign and regulator - I throw the lucas crap away, restoring old triumphs is a hobby for me ,I have learned to do the motors transmissions I do everythin but the paint and powder coating im attaching a pic of the 71 I got and a few others I have done- im glad to answer any ?? jim

paul thank you - a few years ago my educated snooty sister came to visit me ,my other sister had told her be sure and see jimmys ne furniture ,when she walked in the door she looked around and saw 2 triumphs a 57 and 59 in the living roo I thought she *&*& . oh my god she said , I told her these are my canvases a form of art. im a bachelor and these 2 bikes are special very rare the 59 bonni is the first year of the twin carb . I found them on craigs list in 2012 in a shed in Elmira ny both were trashed,rusted misused beyond belief I think they went threw a flood along the way, on the 57 when I pulled the rear wheel apart I found brand new brake shoes I was astounded because the rear tire was worn so bad the canvas was showing why would someone do brakes and not go for a new tire,that gives you a idea how they were cared for-hey they were matching numbers - baxter in iowa had a 59 for sale for a while at 29,000$. so it was worth doing and a hell of a education . I just attached 2 a before and after pictures the before is on the way home in my van . the first thing I did was take a lot a pictures so I know what goes where and they are fun to take to a show , after unloading lots a looking around wondering if ive gone nuts , washed them best I could and started taking the 59 apart lots a pictures along the way, I wanted to get the rusting stopped , the wheels on the 59 were green . lots a stuff went in 5 gal. buckets of kerosene , the frame went to the powder coater , surprising there wasn't muck serious pitting or holes. when I picked up the 59 I droped off the 57. and the 59 went in the Livingroom, mice had been living in the 57's tank and dragged all kinds a nesting material in there I flushed it with muriatic acid with a little water it was so bad but solid nasty job , then took the tanks and fenders to the painter. I have a how too do tape by Hughie hancox. a English man who worked for triumph from 54 to the seventys then went on his own restoring triumphs , these may have been the first 2 motors I did . now the work begins lots a wire brushing and back in the kerosene bucket , they had laid one of them over on its side and the foot peg broke the primary case . I have a glass bead blaster which is a big help , I've found that its always best to heat the stuburn bolts etc before even trying. I took the 59 wheels apart and wire wheeled them to see if they were a canidate for rechroming I was shocked there was no piting and I wondered how well they would clean and polish , they are original jones and dunlops and look good you have to look close to see they have been abused . they polished up[ nice and I think they are more valuable than a new repop rim. the hubs were powder coated and new spokes installed that was a learning process pictures were valuable. im gonna see if I can find some early stage pictures to attach and go for a one mile swim and finish this story later --jim

Wow, that '59 is unbelievable! Fantastic work.

Kinda hard to follow your post, you don't seem to use many periods or commas!

the name of this thread is T100 , that's because when i first wrote in it was about crowlys t100, grandpaul suggested i do a thread on restoring . well when i did the t100c i didn't do the engine , i sent it out , after that bad experience . i started doing my own engine work. this is about my 1959 bonni whichI had more pictures of. and its about a guy with little experience taking on a big and difficult project ! these old triumphs are teachers . This beast has my attention rite now its almost done . every tab and bracket was removed , when I get a little problem i am experiencing fixed i will return with more on the 59 bonniville I did . lowboyjim
