Hi, sorry for delay in replying, working away has its downfalls. these pics hopefully will prove what I have been saying about this particular engine, just because you havent come across it before dosent mean it cant happen,

Kev have you still got your old engine? Might be worth sticking the flywheel back on it and checking position of keyway with lock pin engaged. If it's the same on both engines that would prove a point as the other one has run. What position is the dot on the crank sprocket with the engine as is in your latest photo? It should be almost straight down with lock pin in. That would then match the illustrations in RAVE. I still don't think lock pin was in correctly in your first set of photos showing relative positions of chain links and dots on crank and pump sprockets. Think that has thrown us off course a bit. Maybe the arrow on the pump body indicates 20 degrees BTDC where pump should be off cam and BMW use for pump timing in the factory. I am fairly confident you had the lock pin in wrong when you timed the pump. Rebuild it with lock pin as is and time the pump. I am fairly confident it will then run as it should.

We never disbelieved you, with the drive plate pinned have you got and movement (rotation) at the front of the crank?

Alan what is now very clear is that in the first set of photos he posted with the engine in situ he DID NOT have the locking pin in correctly. If he timed the pump with the engine in that position it will never start while he has a hole in his bottom. :D:D

I agree, but as we discussed on the phone, if a crank web is snapped then this is the only explanation for the keyway and locking pin hole to be out. If he has no movement at the front of the crank with the pin in the back then yes, he must not have had the pin in correctly.:D:D

My bet is he had it in the large hole or snagged on the timing peg, that would give the position on the first photos. In which case the engine MUST have been turnable backwards. Which i asked him to check for, he insisted it was locked solid which it has to be. But it cannot have been. If he used that position to time the pump it will never start. ;);)

Keep it clean Tony, perhaps that's were he went wrong, got it in the wrong hole. I think your right, snagged on the timing peg. We wait with baited breath. ;):D
 
hi, original engine has been broke and bits sold to pay for the work to carry on, pity some people dont belive others , so Ihope you all understand when I say bye and leave this forum. all the best to those who did help.

No Kev in the original photos you posted on here with engine in the car of chain positions, the locking pin CANNOT have been engaged in the correct place in the flywheel. It is not possible. It has to have been either in the large hole or snagged on the timing pin. In either case the engine would have been turnable backwards. There are six timing pins in the flywheel set a 60 degree intervals. With the locking pin in place one pin is 40 degrees past the CPS one is 20 degrees before it. As shown in your latest photo with the locking pin in the flywheel. You made an error and it has cost you a lot of unneeded work. Simple as that. Learn from it. Or basically don't try things you don't understand or that are beyond your capabilities. Sorry to be terse but sometimes people don't help themselves.

Guess that's the end of the matter then.o_O:rolleyes:
 
Hi . update for you all , still got it ( perseverence nd all that sh*te) stripped engine down and got local engineering shop to help with checking /measuring stuff majority of parts ok turns out all we could find was crank APPEARED to be twisted, so another engine rebuilt and car struck up virtually straight away, so my timing methods were right , but hands up I behaved like dick and appologise to all who helped with suggestions Wammers your still God.
 
Now there types a man, big shoulders and all ;)

Nice to see you came back and gave an explanation and apologised for being a bit annoyed.

Thing is, you were all correct at the time, Wammers with his insistence and you with yours, turns out the crank was the d!ck all along :eek:

All's well that ends well :)

Happy new year and happy motorvating :cool:

Seen a few cranks snap but never seen a twisted one.

I heard of one long time ago! However, my dad was a fisherman and back in the day, he took his friends boat over for a while.

One day, out hauling creels, the motor was idling to power the hydraulics, there was a bang and the motor stopped!

Dad lifted the engine cover, had a look and couldn't see anything obviously broken, so put it back down, went into the wheelhouse and pressed the starter and she turned and fired up, but a rumble like he hadn't heard before. Once again, he lifted the lid, looked, saw nothing, but decided to take it easy back into harbour.

Long story short, they pulled the engine & took it to AGRA Motor Engineers who found the crank had snapped clean in half!! :eek:

They were utterly astounded that not only did it start, it took him back in, a good 3/4 of an hours steaming to Macduff!

Even more startling was the fact it kept the timing and ran smoothly o_O

Never seen that before nor since, but it did have a large impact on me which ignited my love of mechanical things :)
