Jeez, the pair two in from the right are - ace thread, keep it coming
Anyone know the diameter of the shaft and grade of steel used??
Should be possible to calculate the force required to do that
I was travelling at 30mph in 5th, so 1500rpm, the valves are 6mm thick wasted to 4.5 over 20mm then flare back out to the full valve face if that helps with your calculations. I make it around 2000N of force, but I know you can bend them on the 12" ring spanner as you turn the engine over after changing the belt if the pulley is left loose (can't you SEARs?).
It was my intention to see just how far an original belt would last, the verdict, 9 years, 105486 miles, Now I have the cover off I can show you what happened.
Now as I do these repairs weekly as a hobby I had no worries on leting the belt interval slide, and I had the spares aside for the job when it came up anyway, so tomorrow evening we should have a COMPLETE how to on belt repairs.
interesting stuff though its shown how long an original belt might last in certain conditions
Great news on the succesful rebuild. I can't wait for the how too guide. As someone else has said "the sound of belts snapping before their time" is not something I want to hear either.
I am impressed on the 11 hour turn around too.
did you have to take the engine out of did you work on it in the bonnet?
Also did you have the head skimmed, as you fitted a new headgasket?
It was 11 manhours over 2 evenings due to real work encroaching on my time, the head wasn't skimmed but it had no corrosion and was only 0.02mm off true so there was no point with it being so far in limits, plus why waste capacity? The head was stripped though and checked over with the water pump and valve stem seals being replaced.
Well played again Smaky - at this rate, you could turn it into a sport
LOL, I've not heard from Ned since he laid down the 1.5 hour cambelt challange, I think an 11 hour rebuild means the 1.5 cambelt is easily achievable. And I just can't wait to get this twinny Chris 156 bought last night apart, then I can get pics of a 2.0 156 too, there's a few subtle differences.
I'm just puting all the photos together now for the strip thread, hope to have it up this afternoon.
Last time I went to Tesco for a pair of Marigolds I had to ask what they looked like.
Smaky, don't answer this, but to me your degreaser might be trichlorethylene based, I used it in the early 1950's to clean tubes before silver brazing cycle frames.
Great work S.
