mudcow007 Posted September 25, 2015 Share Posted September 25, 2015 So, i was given this last year It's a DT175MX 1979 single shock it had sat in a garden for about 8 years (I reckon longer) on its side, flywheel up (without that side of the casing on) uncovered an unloved The bloke who gave me it said he bought it with his paper round money an was genuinely gutted to see it go - cant see why Anyways, as soon as i got it home took the engine out an left it as that fast forward to tonight an thought I would attack it After fighting with rusted rounded off screws, I managed to get the clutch side cover off 8O :cry: I reckon it will need new clutch plates......

slice Posted September 26, 2015 Share Posted September 26, 2015 Yah think! Looks like the 2 Suzis I jut bought, nothing is beyond repair it's just can you be bothered. The thing is these little bikes turn into really smart little bikes when they are fully fettled. Link to comment Share on other sites More sharing options...
Moderator Cynic Posted September 26, 2015 Moderator Share Posted September 26, 2015 Ironically that engine will more than likely be fixable, engine rebuild is an engine rebuild.Stripped cleaned new clutch and rebore, bit of vapour blasting and a crank rebuild and its as good as any other. Frame on the face of it seems ok. Sw arm is scrap but the shock will most likely be good.Hubs too will likely be ok as well. No I don't think its a write off if your enthusiastic and the bike has sentimental attachment, like mine I have had it getting on 30 years.But you can buy a working dt with mot for under 500 quid if you just want it running, can you rescue that with that amount of cash, ?? 3 Link to comment Share on other sites More sharing options...
mudcow007 Posted October 2, 2015 Author Share Posted October 2, 2015 Hello all cheers for the words of encouragement, others have told me to scrap it......but i hate throwing stuff away an lets face it if everytime something got rusty it was scrapped there woudl be nowt left! bit of an update Bit stuck on taking the head off, one of the alloy "slugs/ bolts" is chewed to buggery. any ideas? also struggling with the lock nut on the flywheel oh found a bit of damage to the case, there is a crack under the selector shaft, hoping thats not terminal...... updates to follow Link to comment Share on other sites More sharing options...
Moderator Airhead Posted October 2, 2015 Moderator Share Posted October 2, 2015 regarding the cylinder sleeve nutAlways use a 6 point socket on these aluminium nuts, never use a 12 point one so get the correct sized 6 point one, shove a strip of medium / coarse grit emery cloth into the socket and tap it down onto the nut...blowtorch the side of the nut to get a bit of heat into it and try again 3 Link to comment Share on other sites More sharing options...
blackhat250 Posted October 4, 2015 Share Posted October 4, 2015 (edited) Yeh, my dt400. had 3 stripped cylinder sleeve nuts, . I drilled down thru them , [ 6mm/ 8mm/10mm/ 16mm bits] made a puller and dragged the barrel off, Heres the puller.

blackhat250 Posted October 4, 2015 Share Posted October 4, 2015 dDrilled right thu studs too, measured the depth with Vernier, so never touched cases, left small stubs of studs, mole grips- and new studs, 2 Link to comment Share on other sites More sharing options...
mudcow007 Posted October 6, 2015 Author Share Posted October 6, 2015 bit of an update, managed to get that pesky aluminium stud out....tried heat etc an still wouldn't budge so ended up smacking a smaller socket on an was able to get a grip on it still havent managed to get the barrel off though, seems stuck solid - any ideas? bad news though, the crack i found by the selector shaft looks quite bad..... thoughts? is it game over? the engine/ frame are matching numbers so would ideally like to try an keep them together Link to comment Share on other sites More sharing options...
Moderator Cynic Posted October 6, 2015 Moderator Share Posted October 6, 2015 Pssst, I think the engine number is on the OTHER sidecase.Just change this one, at a guess I would say that damage is from ice. 1 Link to comment Share on other sites More sharing options...
Simon46 Posted October 7, 2015 Share Posted October 7, 2015 Mine had landed on a rock and cracked case. Shaft was bent too and difficult to get out. Found good shaft and case in USA and kept matching numbers. Link to comment Share on other sites More sharing options...
KevtheRev Posted October 7, 2015 Share Posted October 7, 2015 I used stuff called " Multi Poxy Aluminium " , a type of two pack epoxy resin containing aluminium particles , to fix a hole in a KLR 250 crankcase . Worked a treat . A more modern front end with a disc brake would be an easy upgrade if you decide to go ahead with it . I hope you do, my first bike was a DT and they're a great little bike . I'd say most of the essential parts are still available . Link to comment Share on other sites More sharing options...

blackhat250 Posted October 8, 2015 Share Posted October 8, 2015 Bloody ell " that's the worst av seen ,,, To remove the barrel , make a puller like my pic. I used the centre"s of old 3 leg pullers, welded to a bar,. , IF YOU BELT IT WITH A HAMMER , = broken fins, Link to comment Share on other sites More sharing options...
