Gunna put oil grooves in new se comp sprocket and in the pic it shows them inline with the sprocket spokes, It looks to me that with grooves inbetween the spokes it would get better flow, Unless there thinkn oil running down spoke would be better,So ? is does it matter where I put the oil grooves?? Thanks..

 

Use the spokes, you'll get more area for oil to run down when you shut off motor.

 

They should come like that from that factory.
How ya gonna do it?

 

I would think it wouldn't lose as much of it's strength/integrity with the material removed in line with the spokes.

 

Yeah I hear that man, good point.. Thanks lonerider2, good point also..
They do not come from factory with the oil grooves, It was suggested by some people who already installed this comp that it was a good idea to put them in.. How do I do it? how bout a ballend endmill bit, not only that I can remove same amount of metal from each oil slot. outta work huh????

 

Have you seen what it looks like on one of those demo dish washing machines with the glass front at Home Depot? That's what it looks like in the primary when it's running. The ones I have seen galled is were the v fork drives in the crude cast ribs.

 

Is it necessary to cut the grooves in the sprocket? I have ordered the SE compensator and should be receiving it sometime next week. Looking at the installation instructions, nowhere does it say to cut grooves. If it needed grooves seems like Harley Davidson would have designed the sprocket with grooves.
What am I missing here?

 

What you're missing here, is that Harley does not think of everthing, and often times uses other's ideas like cutting grooves in the compensator to get more lubricant needed to vital areas.

 

I wouldn't say it's absolutely necessary but it would be a good idea to do it while you have it out. If Harley Davidson did everything perfectly, you wouldn't be replacing the comp anyway. Ball milling would probably be the best way to do it. It would allow you to remove the same amount of material in all three spots. If you don't have the know how or the equipment, take it to a machine shop. I recently had two done locally and it was only $40 to get both of them done. If I remember right, you can take out 60 thousandths and it will be perfectly flush with the bevel edge around the center circle.

 

Yeah only took 40 thousandths out and featherd back for better flow, did not use a ballend cuz had to do with carbide, hard steel. Well worth doing cannot damage anything.
