Re: My long time friend the pransing horse

Why is this side so worn, the side is generally a low ware area.

You could say that area has the most metal so you take it as a metal expansion problem or poor machining. Then that could explain it.

Re: My long time friend the pransing horse

I have been thinking about the crank problem. I'm glad it's gone, binned in fact. Why did the seal leek, why does the gasket look like it leaked and why was the piston failing? I know one thing, it was a hard working motor. I am surprised by how clean the crank area was. Leached clean. It must be so...

Re: My long time friend the pransing horse

Most of the sound guarde that is not heald on by the cover or straps has fallen off image.jpeg What's interesting hear is the colour variationon on the stainless steel straps. I'm not 100% sure I know what it is telling me but hear is a go. The darkest part is the hottest, when the exhaust gasses co...

Re: My long time friend the pransing horse

I would say I could see a sealed line through there. image.jpeg Moist with oil image.jpeg Still 100% advanced. I have never hearted it ping. If I were in a hurry I would move it further by 1mm and take my chances. image.jpeg That's not good in any way. It could easly be one type of failure to anothe...

Re: My long time friend the pransing horse

That has so much information. I just wiped it with a cotton rag.

This will be my last planed rebuilde. It works with one irritating action. The crank feels out of balance.

Re: My long time friend the pransing horse

Note the dark section for the gudgeon pin image.jpeg Wossner does not use oil holes to loob the pin. Instead they use these slight recessed passages. I guess every time the piston goes past the inlet port hole there will be a slight difference in preasure between under the piston and transfer port o...

Re: My long time friend the pransing horse

No sign of cracks on the inside of the inlet image.jpeg That side is taking a hammering. Having said that the were rate has considerably slowed since adding the lubricating holes and slots. Will put those there from the start for the next piston. The bottom edge is also heavenly worn so will put a b...

Re: My long time friend the pransing horse

While generally wiping the oil off the piston with a rag I inadvertently wiped the blow patten off the top of the piston. This is what did not come off with a light rag wipe. The carbon build up is the dead area that gets the least wash from fresh charge. I'm ok with the uneven patten left to right ...
