RE:Crankshaft cam chain end

[BERNIEHUMBER]

HI:
I have a crank in this rebuild that has two woodruff key slots not just one.
I figure its for the version that had a crank pulley on the end for some power take offs.
My one question is what size is the key and the second question:has any one else dealt with this before.
I have included a pic.
Thanks

 Hi Bernie,
  What engine are you rebuilding?  The crankshaft that uses the second woodruff key would be the 843
The crankshaft doesn’t fit under the 821 timing case cover.
  I double check that tomorrow . As for the woodruff keys , I purchased an assortment package from O’ Reileys  but had to file them down to fit . They are soft and easy to detail with a good file.
  I’ll see if I saved the package for size or I can also measure my cranks.

   Nevrmind if you have a tc

HI:
Its an 807 engine.
Some of them had a pulley sticking out the case cover.
Can I grind off the end to where the cam chain sprocket is?
Long ago I thought I heard of someone doing that.
Any other ideas?
Thanks

Yup, some 807s had the pulley.  Mine did.  I still have it.  It's the best place to power a compressor from if you fit AC.

I test fit the  blanked off cover over the end, with pulley and bolt off on an 843, no interference. I think just plugging the end of the crank might work, although a collar to hold the chain sprocket in place might be needed.

HI:
Thanks for the get backs.
There seems to have been made 2 styles of cam covers made.
One has the hole through it(complete with a seal) and the other designed to sit out farther with a rise for the extended crank.
I dug around and found one of each,the one with the hole has a Aluminum extended cap welded on to compensate for the added length.
I just ordered an assorted Wordruff keys in metric as all I have handy are imperial.
The piston ring compressor I have only goes down to 3.5 in so I put the smaller sized one on the same order.
I have had the 807 in bits for years so its amazing how the little missing parts now need acquiring.
The head was done 8 or so years ago buy a French guy who was a Renault specialist.
Oh I am sure there are some hurdles yet to come.

I do have an 843 Block with the front end pulley.
Keep in mind it is very close to the shifting linkage at least on my S1.
I turned down the pulley as short as possible but it is still very close to the linkage.
Although it is pretty nice to have a possibility to turn the engine over by hand by the crankshaft bolt.

HI R:
I welded an Aluminum  cap  on the cam cover to extend over the end of the crank bolt and washer.
My worry was the pulley dia.
