Cam shaft end play?? - Harley Forum

TESTECLEEZ · #1 02-03-2008, 05:44 PM

Hi All,
This is my first post here and unfortunately I am writing to ask for some tech advice.
I am putting a Andrews EV-27 cam in my 89 FLT.
Now my problem is< I need to know what the proper end play is supposed to be.
According to the instructions that came with the cam I put a .055 spacer shim along with the trust washer and I have a gap of .024. My manual says the end play should be .001 to .050. That seems to be an awful lot of play.
Has anyone installed one of these cams in a 89 Evo?
Any help would be greatly appreciated.
Thanks in advance

If my memory serves me right .050 is your wear limit .024 is about in the middle. It may seem like alot but you should be good to go. Always use the manufacturers recommendations and use your service manual for reference.

Thanks for your reply. I just heard back from Andrews finally and they say the end play should be .010 to .015 so I guess I am going to have to spend another $10 for gas to pick up a $2 part.

Keep it between the ditches!

The.024 is well within spec but like I said always go by the manufacturers recommendations.

OK, Now it seems I have another problem. I was just talking to a friend and he said I should check the cam gear measurements because I might have to change the pinion gear to match the Andrews EV-27 gear.
When I decided to change the cam to Andrews I did so because it was supposed to be a "bolt in operation."
I am so close to putting this motor back together and these little problems are driving me nuts.
How hard is it to get the pinion gear out of the motor?
One more thing. At the front cylinder base there is a hole but there is no hole in the gasket for it. What is this hole for.
I can't find any info about it in my manual.
I really appreciate the help I have been getting here and for this I thank each and every one of you.

Keep it between the ditches!!

Testecleez: I saw this response to that same question on another forum. I hope this clarifies it for you. Sincerely: Shovelmike.
O.K. lets start from the larger holes on the left side of the clyinders, those holes are just extensions of the oil return that comes from the head, that oil actually returns to the bottom end via. a small hole a little ways up from the base and lubes the piston, before running down the cylinder into the crankcase. The only time that a gasket that has a hole in it is used is when you would be setting up for a longer stroke in which case you would block off the original small hole with a piece of tubing, and that will still allow the oil to go through the base gasket that has the hole, into a hole drilled in the case, or a slot, to return to the crankcase On the right side of the cylinder, there should be no hole in the gasket unless for some reason you would want to run a panhead inside oiler top end, if there is oil coming out of the little hole in the case it should plugged or tapped and a set screw installed, it is not used on a shovelhead with an outside oil line to the top end.

Testecleez,

If Shovelmike answered your question then your good to go. But I think I may have read your question differently. Just trying to clarify for myself as well. Are you speaking of the (2) oil return holes on the base of the jug itself? The third small hole receives the pin on the block for alignment. If I read you right and your referring to the oil return holes where they meet the block, only (1) hole per jug is used for oil return. The jugs are identical front and rear and the additional oil return hole is so the jug can be used for either the front or back when assembled at the factory. Dont take my word as I am no expert. Can someone clarify. I'de like to be positive. I will be re-assembling my top end this weekend. Of course I will be reading the service manual again before re-assembly. Thanks. Botz

The hole I am talking about is in the right side of the case. I went out to my shop and looked again and dicovered there is no corresponding hole in the jug and that is why there is no hole in the gasket.
I hope this helps you out but I am no expert either but by the trime I am done I might just well be concidered an expert.

I apologize, Botz and Testecleez, on re-examination I see my post was in reference to a Shovel rather than Evo (which Testecleez is working on). Temporary (I hope) senility I guess.

Hey ShovelMIke....

NO Sweat.....I get that too (Senility) and Im only 45. I has a few senior moments yesterday while working on the bike. Went into the house to get something then for got what I needed. Whew, thats bad! I saw the hole Testecleez is referring to. Its behind the front tappet block on the case and is on almost a 45 degree angle next to the cylinder stud hole area. On my bike that hole goes down about 1/4 inch and stops. No idea what its for. Botz
