- Well got my rebore back +20 Harris pistons fitted.
After painting the barrels and exhaust clamps with heat resistant paint I left them to dry for an hour then put them in the oven on a low light, gas Mk 2 for another hour. Then they where dry enough to work with.
Just refitted my T140E Barrels using your Wooden base idea and home made ring compressors made out of 2 slices of a stainless steel fire extinguisher and 2 tie wraps. It all went swimmingly thanks again John. Keep up the good work. Bill
Hi Bill :-) nice one,
it goes to show you don't need to spend a fortune on special tools and simple is usually best.
I must admit I was a bit gutted when them secondhand rings did not work
but at the end of the day the rebore and pistons was the best choice.
She is running fine now.
Great video John, nice new pistons and rebore. Its going to sound and run great can't wait for the rest of the build and start up.Looking forward to the part John, great work.
Cheers, Jeff.
Hi Jeff, :-)
I'm really pleased with the result, thank you.
Hi John I am going to use your wooden base idea tomorrow, I'm renovating a 1966 tr6 and have found your videos a god send. Dave
Hi Dave :-) thank you, that wooden base thing is dead handy, it's like that other pair of hands you're always looking for!
Good luck for your TR6 restoration.
Great to see the barrels back John,looks like they've done an excellent job.It will be well worth it in the long run.
Hi Steve thanks :-)
they have done a first class job and soooper quick, well chuffed!
@@lunmad ypyhh
Hi Lunmad, from here those pistons look like 10:1! I am putting 8.6:1 in a T140E that have a dual plugs head to try to avoid detonation...
Your knees will be in the breeze very soon ,Very nice John, going to run like new .
Hi Steve :-)
thanks, don't forget the rain in the face :-D it is summer here ya knows!
She's looking as fresh as a daisy.
Hi Ed :-)
Shame the hot paint don't smell like a flower,
Great job, and really neat support thingy for the ring placement! John, mine isn't as complex as that, but in the placement gasket set I've been sent three barrel/cylinder head gaskets, two thick ones , and a paper one. It's a 250 cc Yamaha, four stroke, with just a timing chain going through.
I cannot remember what came off the base, but, my question is, would it matter if I used the thicker one, rather than the paper one? Cheers, Den, Swansea.
Amazing how archaic these engines were when compared to Japanese engines.
Hi Derek :-) how right you are, all the same principal though, I remember when the Honda 750 4 came out and destroyed what was left of the British bike industry all for the want of some investment as usual.
Ooooh! Shiny shiny. You can just tell she's going to run lovely with those. You must be more than chuffed, now that you've finally done it. Great you got them done quick once the man was back. You had to give the barrels a coat of black just to smarten them up, now that they've got 'posh' pistons and rings. I expect you're at least one step beyond this video in real time, so you'll be close to firing her up by now. No spoilers though eh? I want to see it unfold. I'll be dying for a chat by the time I know it's done! Sadly the weathers pretty shite all week. Typical innit. Going to need a hand with new inner tubes on the Enfield, I'll be getting them ordered this week. If I run down with the wheels, would you give me a lesson/hand with them? For beer.
Hi Pete :-)
late with my replies as usual sorry bout dat.
I'm really pleased with the result, from no pistons to pistons and rebore in two days that must be some form of record.
Any time for a tyre change lesson.
No grooves in those barrels.Beautiful pistons.Going to run like new.
Hi Derek :-)
I'm pleased with the machining, hes done a real good job.
Looking all nice & smart
Cheers triple :-)
Harris pistons and rings are working well on my T120.Virtually no oil burning.Get it up and running soon.
Hi Geoff :-)
Late with reply as usual sorry bout that.
I'm pleased with pistons, according to machinist Harris do not use low expansion alloy as Triumph used, so a little more bore to piston clearance is needed.
Hi John, It would be most appreciated if you could you post the size and distance apart dimensions of the slots in your wooden covers? I’m about to make a pair before I start stripping my T140 head and barrels.
Thank you for your great videos. Best wishes, Anthony
Hi Anthony :-)
The approximate dimensions of my board are 9"x 8" the hole for rods are 1"x 1.1/2" with 3.1/2" centres
then sawed in half across rod holes, I used a piece of laminate flooring as the board.
Hope this help John.
try measuring your motor
they make spray paint for that
That would ruin all the fun .
Hope that's not oil based paint if so looks like a fire to me! hope you run the old bitch rich and cool lol☺
Hi Sheridan :-) I'm not sure what the paint is based on but is is for cylinders, and is called Cylinder Black funnily enough :-D
there is also one similar caller Pot Black.
I do run it a bit rich I also run with slightly retarded ignition timing, due to the available fuel nowadays.
Christ almighty what a mess... you haven't finished painting your fingers yet !! 😂😂😂
