Robbie, this pulley balance is actually very important for the health of the engine, especially the #4 main bearing.asiab3 wrote:I've been feeling pretty dang depressed about everything on this engine that other people need to touch. I got my rotating assembly back from the balancer, with the crank pulley in a ziplock bag. This is the actual conversation I had with the monkey at the front counter.
"But isn't the pulley part of the rotating assembly?"
"Well yeah!"
"Then why didn't you balance it?"
"We don't balance the pulley."
"But didn't you charge me to balance the complete rotating assembly?"
"Well yeah!"
"So then why don't you balance the pulley"?
"It isn't part of the rotating assembly."
Do you see little metal weight(s) crimped inside the outer pulley edge?
Can you establish that the pulley does not have run-out? There are two directions for run-out.
One is the classic wobble from people who try to pry it off the engine. This is wicked.
The other is radial runout that makes the belt loosen/tighten/loosen/tighten. This is even more wicked.
Did you just walk out huffily, or did you say,
"I'll pick it up next week.
By the way, get rid of the run-out before you re-balance it with the crankshaft,
thanx."
Good luck with that. I will happily take any used factory cooler sitting anywhere in a garage pile under the bench. The quality is good enough that you can:asiab3 wrote: And repacking the CVs will give my mind the serenity it needs to track down an oil cooler not made in China.
a) fill it with gasoline, slosh around and drain through a white paper towel. If any metal flakes, you can either reject it, or be ready for an extremely comprehensive wash program.
b) pressure test to 80 psi.
Cleaning can commence with a mild air pressure + solvent wash, this is to disturb all internal sedimentation in the passages, then have it cold-tanked at a machine shop (request specifically !! !! that it not be tanked with any sandblasted parts? like? duh?,
then carb spray + shake & shake rinse until it comes out clean on a tell-tale paper towel.
That's serenity for ya, right there.
