Reassembling my crossflow

[dakazman]

You two are well on your way . Thanks for the pictures showing the amount of removed and where.
I posted a picture here to only give a perspective of a stock head to compare the work done on your heads.
  The areas circled in yellow show the most difference.

Thanks for the pictures i see all the differences  im just going to clean mine im not gonna remove anymore material cause im using the same pistons and it would only reduce the compression ratio

I just recieved my workshop r15 r17 manuel it was printed in 1971 very detailed as the 807 but not the 841 or 843 there is a book another book that came with it it amendment there is info on the 841 specifications and showing the other type of liners im waiting on a r16 Renault workshop manuel and one from fuego

 Now i have been  reading this book and  i was reading about the drive gear for the distributor it says put at tdc and the slot as to be parallel to the camshaft now here is where i got confused when i look at the wedge the engine is at tdc and in the picture it is parallel to the cam no problem
But when i look at the crossflow they write put tdc then there is a diagram showing to put the drive gear at 53 degrees now is it because if you put it at 53 degrees when you put it in as it goes into the hole it will turn on the camshaft gear and end up parallel to the cam  wich would make sense
Thanks

  Thanks for the heads up . I purchased the same manual r15/17 first edition 1971.
I found a Renault website called Renaultclub.us.  No pdf manuals there or wiring diagrams. Some
Parts for sale... Gordini specs are well hidden.

I didn’t want to touch the block but i just realized i have a problem at first i wanted to know what position to place the distributor gear but before getting an answer i went to pull it out to see if id place it at 53 it would slide down and end up parallel to the cam  but by doing this i discovered a big problem so i will have to take the block apart

The problem is that the distributor drive gear was rubbing on the head when i pulled it out i saw some metal chips here are the pictures the bottom of the gear you can see where its rubbing

Now i have been  reading this book and  i was reading about the drive gear for the distributor it says put at tdc and the slot as to be parallel to the camshaft now here is where i got confused when i look at the wedge the engine is at tdc and in the picture it is parallel to the cam no problem

No, the drive gears are set differently depending on engine type.

The wedge drive gear should be parallel when at it’s final (installed) position.
The crossflow should be at 53º when at it’s final (installed) position.

Also note where the slot offset is intended to be.

[califkid_66]

Ok thanks it was bothering me it wasn’t clear my y engine is 843 so that would be 53 degrees
Now im still waiting on some book i have to figure out why the bottom of the gear is rubbing on the head there must be a way to adjust the height to pevent the rubbing 

There is only two reasons possible for this rubbing that i can see is that one the shaft is to low
Or the head was not installed using the alignment tools
I need advice for this one
Thanks

[GavinT]

Yep, that 53º is common across all crossflows which includes the 843.

The drive gear will contact the head if there’s no gasket installed.

If you tighten down the head without the gasket and attempt to turn the crank, you’ll very likely beak a tooth off the dizzy drive gear.
Ask me how I know.

[califkid_66]

Thanks for letting me know the position it needs to be
 Oups little mistake when i was talking about the rubbing it wasn’t on the head my mistake you can see in the picture it’s rubbing on the block under the slotted gear drive so this part is not affected but the gasket its below it looks like the top of the oil pump shaft is a bit short and when the drive gear is installed it is to low and rubs on the block it is to low

[GavinT]

Apologies - I missed that post.

By the looks of the brown oil stains on the block where the dizzy drive sits, it isn’t rubbing on the block.
When the engine is running, the camshaft will tend to lift the dizzy drive on it’s spline.
The pic of the lower outer rotating surface of the dizzy drive, while not perfect, looks OK.

Are those metal chips on the top end of the oil pump shaft?
If debris is suspected to be in the engine, take off the main crank caps & rod journals to check.

[califkid_66]

Yes there is metal chips left when i lifted the gear off   
i remove some chips if you look at the pictures you can clearly see under the gear and on the block where it rubbed or more like  grinded enough  to cause some damage
this is not normal
there is grinding causing metal chips like i wrote before and yes when the engine will run it might push it up the parts might slightly rub with oil in between but not to the point of grinding and making metal chips and causing damage to the parts
In the pictures i can clearly see where the chips comes from i know there is a problem i just need to know why it did this and how to solve this

[GavinT]

Ahhh, OK califkid, it looks like we were working at cross purposes.
I now see the scuffed areas you’re talking about.

The actual damage pictured likely doesn’t matter much but the potential for debris in the oil is of more concern.
Best to remove the crank main caps & rod journal caps in order to check for possible damaged bearings.

Be sure to mark each bearing cap so they go back to their original place & original orientation.

[califkid_66]

Yes i am going to take it completely apart
But i have to find out why this happened
I am hoping it was because no alignment tools where used and the distributor was prying on the shaft causing it to rub if that is the case i will file and sand down the damaged parts and with good head alignment it should be ok
But if someone as any idea or as had similar situation i would really like to know
Thanks
Because this engine is starting to anoye me a little specially when i have this in the garage waiting to be used

[GavinT]

Could only speculate as to where those chips came from.

The odd thing is that there seems to be a couple of chips on top of the oil pump shaft itself.
Perhaps examine the location tang on the dizzy itself to see if it’s damaged. If so, that might explain it.

[jbcollier]

If you don't use the proper alignment tools it is very common for the distributor drive to self-destruct.

[califkid_66]

The chips where from under the gear i am gonna order the alignment tool
My question is are the damages i have due to misalignment of the head
and if i files and sand the damaged to remove the damages if i use the alignment tools will it be ok or do i have to change the gear
I have not put the head back on and didn’t turn the engine it was like this when I got it it’s just that when i pulled the gear out i noticed the damages
