David Brown 1412 smokey!

[elfinwood saws]

It,s just to smokey to run in the shed, so did a compression test and 300psi on number 1 and 200psi on 2,3,4 did a wet test and they all came up to 300psi so piston rings are badly worn on 2,3 and 4 so when it got to dark to work outside i decided to to strip down the engine in the shed, when i got the pistons out, it was a case of worn rings, so i,l stick rings in it, grind the valves in and i,l test the injectors and it,l be good for another 30 years.

how much is a set of pistons, would it not be better with new 1,s ,

[elfinwood saws]

I,l give them a clean tomorrow and measure them to check for wear if they are not worn they will go back in, rebuid kits are available 450pounds.

Ah nice to rebuild a decent engine ! You going to hone or deglaze the bores ?

[Rich2484]

There's is always one thing about a rebuild that I really hate, and it really puts butterflies in my stomach.

 

Firing it up for the first time after all that work. It almost makes me not to be the one that turns the key.

When I fired up my first engine rebuild (Ford 5000) the old boy I worked with was not around.

No, he was hiding round the back of the tractor with a 2 pound hammer and was clouting the drawbar in time with the engine revs as I cranked the engine. BANG BANG BANG BANG.

:lol:

 

I'm going to have to remember that.

 

My first rebuild was a Mini Cooper engine when I was ten. Skimmed head, stage two cams and ported and polished. I swear I was ready to puke at turning the key.

 

The second big rebuild was a Massey 35x three pot engine. Full rebuild. I was working with a mate and when I said put a bit of oil down the cylinders before to allow rings to bed in better he put loads in each one and for good measure put some in he intake. It smoked the college workshop out. Done nothing it smoke for ages until it fired up.
