I am trying to verify the cam on my 82 Shovel FXR. Anyone have any ideas. The dotpeen stamping on the cam is 3B996. It could be 38996.

Thought

 

Picture up what your seeing

 

Thanks, i found what I was looking for. I removed the cam completely and it is an Andrews B grind cam.

 

Andrews B is an old design and yea it gets the job done BUT they make a BH for hydraulic lifters the plain B is a solid cam you did not say what you have

 

This bike has a 98" big bore stoker with solid lifters. Fresh rebuild on the motor, but it has been sitting for some time, the best I can tell. I had a local shop verify the 98" crank and perform a leak down check for me last year. The results of the leak down test was 5% on the front and 3% on the rear. I love the bike, but I am having a hard time justifying having it not ridden much. Considering selling it, but I wanted to confirm the cam setup.

 

Andrews B is small for a 98 inch motor - different equipment you get different results in a leak down - i would not be happy 3 and 5 percent on my equipment but again different in pressure has an effect and gage quality has an effect and what did they do with adding oil or not - lots a parameters in play

on my equipment 3 and 5 would tell me the piston to wall clearance is too tight and or the rings gaps are too small as well or even total seal rings that are a no go for me - we would go looking - but again thats my equipment in my shop not the one you went to

so get it running and ride it then if its not you sell it
