It puts a new take on a 'split crank', it's not meant to look like that!

I've seen several cranks break in the same place over the years, sometimes the car will still keep running and will make a noise like a big end knocking, but obviously not at big revs !
It can be caused by not leaving a radius on the edge of the bearing surface when regrinding but in this case it doesn't kook like it. If used in a single seater car bottoming the bell housing on the track on bumps also causes it. Last edited by GORDON STREETER; 30 May 2022 at 17:32. |

I had an A Series crank break, one of the journals broke away from the web. It was the fabled EN40B as well. The front pulley was missing, never did know if it was cause or effect. I suspect cause.
This was at Oulton Park. One kind marshal gave me the pulley back. Sent from my AC2003 using Tapatalk |

Cranks breaking at the rear web normally mean an out of balance (or loose) flywheel/clutch assembly or bottoming the bellhousing out on bumps. I have taken engines to pieces that were running and found the crank in two bits. Three main bearing ones seem to fail more and I remember the old 1340cc Ford Classic engine (that was a slightly longer stroke) was forever failing if revved too high but the 997/1200 cranks were bullet proof.
Sometimes they "could" have been dropped in a workshop during a rebuild possibly starting a fracture that would fail in the future, I have seen it all in the last 50/60 years |

Sure is a shame as the rest of engine is lovely. I have a set of pistons but finding a crank is proving difficult. Mind you I have not asked MG David yet.This is a long stroke FJ 1098 engine. I am told we could use a 1275 crank but there needs to be some work done on main journal to make it fit. Anyone know ?.BTW I have spoke to Nick Swift. His reply was " blooming long strokes "

I seem to remember that 1098 engines had 1.75 inch mains except for some late 1098 midgets that had 2 inch, the same as 1275s. Putting a 2" 1098 midget crank in a 1275 block was a way of getting a 1400 + engine IIRC, so in theory a 1275 crank should go into a 2" mains 1098 block. 1275 about 2.5mm shorter stroke though. Bore centers are a bit different as well!
Probably no help at all!! |

Ah yes the days of using cranks to tune your car/engine. When it was mainly cogs in there. Now we have more tools to fix it

There is some doubt as to which City Ordinance applies to the licensing of the minkee, is it 47B or 132R?. The Officer of the Leuw needs to clarify this with his superior.

I'd forgotten that 'Allo, 'Allo had taken their use of the stupid policeman from Peter Sellers' performance. Thinking about it, was it ever acknowledged that it had been borrowed?

THe old scatter crank trick eh. Customer of mine managed it with a short stroke 5 bearing. Still no idea why, no warning just bang. He was leading the race as well.

Well now you have the truth !!
Almost 2,000 times more particle pollution is produced by tyre wear than is pumped out of the exhausts of modern cars, tests have shown. |

Yup which is why they now propose taxing EVs. Not one of these numpties has learned basic physics.

The covid lockdown had no effect at all on worldwide CO2 levels . And the 80% odd reduction in traffic had no effect on particulate emissions . https://airqualitynews.com/2020/09/0...n-in-scotland/ One of the few reports that was allowed to be shown . When a German transport minister did an online TV report saying the same thing , it was made to disappear very quickly . So the lies will still carry on to take more and more taxes from everybody . |
