Hi all,

 

after introducing myself, I would like to ask for some help with camshaft timing on the engine I’m rebuilding (1293cc, minispares MS Evo 002 Camshaft).

 

The new sprocket I have seems different from the old one ( as shown in the comparison photos ) . It has a longer face / different hub geometry. When I fit the new sprocket, the camshaft end float becomes excessive, but with the old sprocket it is within spec.

 

Would it be acceptable to add a steel washer as a spacer on the outside face of the hub, (as shown in the “adding a washer here” picture), to bring the end float back within specification?

 

This is the only solution I can see at the moment.

 

------

After this is solved, I need to figure out the camshaft timing. This is somehow a mistery to me and my dad, as this is the first time ever that we are going to work on a non-stock engine / performance cam. 

-Is there a nice procedure here in the forum you guys could point me to ?
-Does someone have a real-size picture of a degree wheel I could print and use for our timing ? 
-Has someone installed this particular cam with a non-adjustable timing kit ? What is the woodruff offset key you guys have used ? 

many thanks 
cheers,

With a performance cam it is necessary to time it in accurately rather than just set it up dot-to-dot on the chain sprockets.

The procedure is already on here, if you do a search, but you need a crankshaft protractor and a DTI. 

The basic timing can be way out due to tolerance build-ups and as much as a 10 degree error has been found.

For accurate setting you can use either a vernier adjustable kit of an offset woodruff key of the correct amount.
