Remember this from a few weeks ago? These are a bugger to get out most of the time but when they’ve been screwed in the whole way along with threadlock and then the allen key drive has been rounded off, they are a bit bigger of a bugger…
I thought about stitch drilling a line to get a slit to drive a bar into then trying to turn it out. I also wondered about welding a nut to the plug. But I thought I’d have to apply as much torque as a Rocket III and so I decided to drill the whole thing out…
Makes a bit of a mess, that will need to be cleaned pristinely/fantastically/excellently/really well, once done. Took as much as I dare out to the threads with a grinding bit…
And then spent a happy hour or so thoroughly cleaning bits of metal out of the crankshaft…Just for interest note the timing slots in the flywheel that allow the T140s to be timed fairly easily by sticking a screwdriver through the timing hole in the casing.
Thankyou.
I am now a mistrustful type of fellow - I’ve given enough money away having my trousers pulled down by cowboys - so I try out my own cowboy skills that I make up as I go along. It’s always a bit scarey opening up an engine I haven’t seen before. But it increases my collection of tools.
Oh, and worn out old Triumph spares.
Yep, that’ll be a good project for you. A little two stroke that doesn’t look that bad. These are clearing 3 grand these days and a Police one with leg guards and a screen, phew, skys the limit! Clean off the bird poo first though…
Just for completeness. Here’s the newly cleaned up sludge trap with a new tube already inserted, the oil feed to the big ends can be seen. This must not be blocked in any way. The engine will still have oil pressure but the flow would be impeded.
Measuring sticks have this feature of a little tail that pokes out the length it’s just measured. So here’s the same measurement in comparison to the oil feed.
New shells were needed. Given the recent rebuild with +10 thou. shells by the dealer they were pretty well marked up. This may be due to an inadequate supply of oil caused by the previous plug being screwed too far in.
New bolts, nuts and the rods are back on. Torqued up they fall easily under their own weight. Note the writing on the rods just to make sure I put them back on the right way… …over
When I rebuilt my preunit Tbird many moons ago I polished the rods and the valve gear. They do look a treat. But cannot for the life of me remember touching the sludge trap so when resurrection time comes that will be the very first thing to do.
Ah, ok. It’ll have a sludgetrap tube. You probably did it but just forgot. You see, when you get in there it’ll be like a whistle but best to check for sure.
thankyou, welcome…over…
