But non the less the actual picture of the actual crack pin nut shows its been hit with a edged tool in what looks like the direction of tighting the nut up (assuming a normal thread direction).

The swarf and burring on that flat head screw looks like it was created by tightening too. Are there any markings on the piston crown that might suggest it's 'had work', DTB?

I suspect Baggo would be horrified by the mecanical/workshop practises used by most farmers.......

as in use whats available....Most of the mechanical parts under the bonnet of my first land rover were held on by bailing twine...and if memory serves one of the manuals with a lwb I owned contained reference to running mud in the sump for so many miles if caught in the bush with a leak.

Not 'arf! I put them there! (on the piston crown) ....whilst working on freeing the seized/rusted piston from the barrel. There's lots of evidence its been worked on by highly skilled operatives other than me.

Erks! These were the timing cover screws....

Hmmm, nice electrical work....

More cold chisel work around the swingarm nut(s)...

This alternator rotor nut must've been a 2 chisel job...
Image

Aaah, more electrical excellence here too...
Image

One of the sump plug/bolt was so rounded-off by a previous owner you can actually see where they'd filed 'flats' (and gouged the crankcase too) onto the nut to get a purchase in an effort to loosen the plug, but the thing that really 'stuns' me is that after doing that.... they refitted the same knackered sump bolt, genius!

Oh.... did I mention the electrical fire its been subjected to at some time also?

Yup, I reckon it's 'had work' previously MrT :)

Ooooph!

Yep, not the sort of work I'd have hoped for!

Actually I was wondering if the piston had +.02 or somesuch on its crown.....

Edit: I've just seen you've err flattened it!

Or needs must when the devil drives. Years ago in Australia, I ran a big end miles from anywhere - there are lots of places like that in Australia!. This was in a 1947 Chevvy Strylemaster. The sump was carefully lowered to preserve the oil, the offending big end cap was removed together with the shells and a couple of inches of my leather belt was wrapped around the journal. Big end reassembled, sump put back, spark plug removed and did 85 miles slowly and with adequate oil pressure to get repaired. So I haven't spent all my life in temperature-controlled toolrooms!

If I could remember how to do these things, I could post a photo I took of a Model T sporting barbed wire HT leads. Wasn't sure if this was a product of desperation or a terrible warning.

Well not a bike and 4 wheels not 2. Had an ‘interesting’ break down in my old fiat x19, car stopped and cut out pulling up to a junction in a 30mph zone after a bit of spirited driving down some local A roads. Car was running perfectly well and ran ok in the 30mph zone until I went from 4th to third approaching the junction, where it cut out. The car would not restart, nothing other than a bit of a cough now and then, turns over fine bit would not start, had to be towed home. So the questions:

Carburettor problem?
Ignition problem?
Cam timing prob?
Something else?

:lol:

As a guess I'd say ignition.

Take out a spark plug and see if it sparks when turned over, if not then check the points open (if you have points that is)

To check fuel loosen fuel pipe at carb end and see if fuel runs out when engine turned over.

If still no joy call in a mechanic. :)

Fix It Again Tony. There where two,issues a stuck float in the carb and more worryingly the cam bet had jumped a couple of teeth :shock: :shock: :shock: given its an interference engine I’m lucky the pistons didn’t mash the valves!

That's quite serious as it shouldn't happen, for obvious reasons. Needs a good dose of looking at. Something had to cause it. :shock:

Does the water pump run off the back of the cam belt? If so, that might need checking.
A bit like the old 70s Lancia Gamma where the power steering pump ran off the cam belt. Cold day on full lock = jumped teeth = wrecked engine. Not good.
The world looks so different after learning science. For example, trees are made of air, primarily. When they are burned, they go back to air, and in their flaming heat is released the flaming heat of the Sun which was bound in to convert air into tree.

Water pump is driven from the fan belt. I suspect the issue was the cam belt tensioner, the car has had previous head work (not by me) and the belt was reused and not tensioned correctly. Anyhow I have a new belt and tensioner to fit and I’ve rebuilt the carb. So hopefully it won’t happen again!
