Does no one supply them anymore? :-? Have you checked out the ads in OBM? I can always make enquiries for you with some of the Bath Classic boys if you want.

thanks for your reply BB.on the older engines the white metal was direct cast into the big ends unlike the later engines that used bearing shells which are available,it may be possible to have the old con rods machined to accept modern type shell bearings or have them recast in white metal.if you could ask people at bath classic that would be great.cheers steve :)

Well the consensus seems to be that most people fit later rods & shells. Haven’t managed to find anyone who’s knows of any engineering firms willing or able to cast white metal so far.

I still have a couple of contacts to catch up with tho’

thanks BB. i have found a company in hampshire that can cast the bearings but it is expensive about £300, :o bearing shells are only about £16 but as has been suggested i will have to change the rods for shell type, i was intending to do this originaly as i have a spare pair but unfortunatly the crank on the early tbirds is the small journal the same as the speedtwin and the rods i have are the later large journal, :( i have made some enquiries for some new rods but have yet to here back. hurleys the engineers in bath have been very helpfull and have asked me to take the crank and rods down to them to see if they can do anything for me. cheers steve :)

is that the cost to scrape them as well?????........seems a lot of money if it isnt....hope you find a suitable rod for the motor.

that is the price to cast the white metal then the rods are line bored to fit the crank, so there not scraped to fit as was done years ago by your garage mechanic.cheers steve :)

Hmm, presumably the smaller journal sized rods are hard to get hold of or expensive too? I'll try & make a couple of calls later tonight.

You out & about tomorrow? May be some Bath Classic boys over at the Longs Arms South Wraxall tomorrow (Wed) night or a lot more of them at the Dog & Fox Bradford on Avon on the 1st Wednesday if you are interested.

BB i have just been informed that triumph never did the early con rods with detactchable shell bearings but Hughie Hancox did do convertions of the early rods to bearing shells so it is possible have the old rods machined,a common upgrade was to change the rods and crank to the later large journal type though.Unfortunately i am working nights this week so cant do the longs arms tonight, but will be able to make the Dog and Fox next week what time do they meet. cheers steve :)

I don't think I'm going to make the Longs tonight either!
Dog & Fox meet is 8pm onwards. Me & Ghost (alias Judy & Don) will be out there. Usually a good turn out of ppl, bikes - depends on the weather but usually some old rubbish up there! ;D

actually BB i didnt use the guys in bristol in the end, i check ebay most days and just before i was going to take the parts down to bristol a box full of old white metal conrods were listed which i won for £10+postage, 8 of the 12 rods that came were triumph so i have managed to get it sorted :)

Result! Fleabay does turn up trumps/Triumphs sometimes. A tad cheaper too. [smiley=thumbsup.gif]

Maybe see you at the Dog & Fox tonight?

you can sometimes pick up a bargain on ebay although if it is a rare or hard to find part you normally end up paying if you want it, as there is a lot of armchair autojumblers out their ;D BB i was working till late today so couldnt make the dog&fox but look forward to meeting you all at the imber run. cheers steve :)
