Hi, can anyone help me with my T150 (1973) engine rebuild. Particularly, the removal of the two camshaft pinions. I bought a special removal tool D2213 which should simply screw onto the pinion, once the locking nuts have been removed, and the centre T bar assembly, which runs through the centre of this tool,should then, when tightened, remove the pinion. Unfortunately my camshaft pinions don't have an external thread on the end and the tool is therefore useless. There are two threaded holes in the face of each pinion which I assume are for a different type of extractor tool. Does anybody know what this tool is and where to obtain this from ?

split the cases and take the timing side off with the cams in the case then you can press the cams out/gears off

Bodine is correct, but unless your bushings or the cams are knackered there is no need to remove the camwheels. But if you do .. mark the wheels in situ with marker pen or whatever FIRST !! You never know what others have done over the years … different cams degreed in not according to the manual,etc,etc. We had a Bonnie years back... reconditioned top to bottom, cam timing set to factory markings, kicked it over … clunk .. turned it back .. kicked .. clunk .. hmmm ? Pulled plugs and turned it over by hand .. hmmmm again .. don't think them valves should be there at the same time as pistons ??? To stave off your boredom .. spanner,spanner,grunt ,curse …. " What's them funny markings on cams ? " I could blah,blah,blah .. ad infinitum.. on how we found they were Megacycle that had been brought in by a racer here, then taken to our one camshaft specialist whom had taken a master from them .. and ...and .. made a few sets !!!! A salutary (and expensive lesson) So, as I love those beautiful threes (wish I could show a photo of the last one … turbo'd T150 in an Egli copy frame I built with Suzuki forks & wheels .. brag,brag ..haha ) I hope this could go a little way to saving frustration … and MONEY ! MARK THEM WHEELS !!!! One other thing .. twins, you can get away with a lot of things … threes .. NO !!!!!!! Not a put down by any means .. but if you haven't done a three before, hand it to an expert .. might seem expensive, but cheaper than making minor cock-ups yerself ! You can't cut any corner with these .. these .. these. Never forget " When they're good, they're very, very, good .. but when they're bad .. they're atrocious " Sorry to blither … but good luck. Phew!! I go open another Rich Ruby !!!!!!!!!! … hahaha

Hey Surly, thanks for your message.

I have to split the cases cos the bike went bang on me first time out. The engine was apparently re built by the previous owner (no comeback as he is no longer with us .... I bought from his widow :() No. 3 conrod broke at or near the crank and shattered the lower casing, into 4 pieces about 2" in dia,on that lower side ! Lots of damage, piston, liner, crank journal, valves, you name it. It was a catastrophic blow up. I have the pieces for the casing which I hope I can get repaired, not sure if the crank will be repairable though as it has extensive damage particularly where the bearing caps fits into the journal. I hope I can get this re ground and fit suitable shells, but until I get it apart and inspected ?????
I had already marked the cam and intermediate wheels as you have suggested.I have purchased another type of puller for the camwheel pinions, which I am reliably informed will work ? Left hand case removed just in case I have to press the cams out first.
My main worry at this stage is why such a catastrophic failure to this one cylinder ? It looks like it was re-bored to fit 0.020 oversize pistons, the liners looked freshly honed, well the two good ones do :ROFLMAO:.
I appreciate your post Surly. I may need further advice as the re build gets underway. This is my first triple rebuild.. apart from my kettle that is, so wish me luck, I reckon I will need it mate haha

Sorry for the delay Briggo, but I wrote a fairly detailed reply a couple of days back, which seems to have disappeared into the never - never ? Get back to us and I'll do it again. Hair receding, headaches, depression, anger … ???? Don't worry, just the signs of a dedicated Trident owner … haha ! Hang in there mate, once you've got them right you tend to wish they could come to bed with yer !!!!! … cheers

Hi Surly, sorry my laptop went pop too and has been away for repair.
T150 motor all stripped, I have purchased a refurb crank as mine was s******d out. I'm now waiting to see if the right hand crank case can be repaired without distortion from the weld. Fingers crossed ! If all ok I'm looking at at least one cyl liner, piston, con rod etc etco_O. Will keep you posted. Cheers

Howdy mate, heh heh,, you may need to change that face to a crying one !! While you're going broke, I would suggest springing for a new SET of con-rods for future safety's sake. These baby's just scream out to be revved … aaah.. 8000 revs with an open 3/1 !!! Right, back to reality .. seeing as you've gotta splash out why not think about putting 500cc pistons in, I can't remember exactly which model but I'm sure they were 69mm + 0.040, taking it out to 812cc and bumping the compression to 10 something, giving the bottom end grunt they lack. A true timed 119 (damn) through the flying quarter ! Bugger .. I swore I'd never have another one … but you're beginning to talk me into it ??????????
