My buddy took his bike in for cam chain tensioners and upon inspection, they found the crank had .001 play on the oil pump. Now .001 is a very small number and acceptable is .003. So his is .004. We are having a new style cam plate and cams lifters etc. he simply can't afford a complete overhaul at $3300.00 plus labor for the exchange.
Is he doomed for another early shop visit?

He ain't gonna have the smoothest riding bike. I darn sure wouldn't make a hot rod out of it.
But I do see the reluctance for a complete overhaul. Ouch!
As Scott at Hillside said, I have seen .035 to .005 on brand new engines.

I wouldn't be comfortable with.004. I would definitely check it again in 6 months to see if it's growing, or stable.

Yes, and the .005 guys are beating down the service doors with complaints of ruff riding and vibrations, only to be told "it's in spec".

Hearing your story makes me think you have an advantage there.
Please let us know if your situation changes.
.005 is a number that would definately halt an upgrade in progress, if it were in my garage. No way would I intall parts that I already had inhand, (for a motor upgrade), knowing the likelyhood was high that I'd be splitting the cases in the future.
I'd either put it back together stock while I planned my next move, or tear into it further to get the crank trued and welded.
.005 is unacceptable. (my opinion)

I don't know enough about trikes to know how much of the vibes the suspension absorbs. All my experienced is based on 2 wheelers.

I have a 03 engine here that a guy brought in that only has .001 runout but has been whipping the pinion shaft all around, has distroyed the oil pump, and egged the pinion bushing in the cam plate to where it has .006" clearance to the pinion shaft top to bottom.
Another engine here that has 90,000 on it with an S&S 124 crank has a similar problem at .007" bushing to shaft clearance. If the pinion's roller bearing has more than .001" clearance to the shaft the end of the shaft will whip, the assembly will flex under severe duty, and the shaft or bushing will take a beating.

crank specs
I have a 2003 softail heritage classic , 590 high lift cams with gear drive . I was told that my crank is .005 out . This doesn't seem like a lot to me. He seems to think that I need a rebuild , only have 37,800 miles on it . I would appreciate any and all help with this. So please reply my brothers and sisters.

See if the shop checked the pinion shaft end for wear and clearance to the bushing, this may shed more light on what to do. We often replace the bushings in the stock plates. If the shaft is not that worn and the bushing has a lot of clearance like a lot of these we see. Another option would be a billet cam plate to stabilize things. The feel that I have for this is the pinion bearing may be a little too loose for the guy's riding style so the billet plate will help for a while.
