Learning Alignment from FB

[Freakrider]

Blaster 1's are notorious for stripping driveshafts even when properly aligned, I've heard different theories over the years as to why but never a consensus.

That is why someone came out with the square shafts and midshaft last year!!!!!!!!

And this thread that talks about shimming the motor and pump? http://www.x-h2o.com/index.php?threads/engine-pump-shimming-questions.51928/

except that thread is bad info or as Jr. would call Facebook info

" Look inside the engine compartment at the drive shaft sticking through the hole. Your goal here is to get that drive shaft to be as dead center in the hole as possible. "

Thats some serious facebook info for sure.

The hole the drive shaft comes though has nothing to do with the alignment of the mid shaft to the pump shaft in hulls built these days. Why did management sticky bad info? no wonder people are stripping splines. damn x-h2o spreading bad info. what a garbage site.

I find root causes problems by challenging the status quo, far from a subject matter expert in any field.

If you want this site to be great make it great!

I never said it was great advice, you just said there was not a thread about it.

Last comment on that post by Fred is one of the most important. You have to have the Pump/Shaft, Midshaft and Motor all in the same plane. The shims are what makes this happen.

Better get to writing......

Does that mean DAG will continue to correct my spelling? Lol
I really need to start being careful what I wish for around here............

@Jr. I would pay good money for a hard copy or pdf book written by you, or a collaboration with any number of the wizards of jet propelled water scooters. Especially one on driveline alignment that covers stock to all the problems faced building up an aftermarket hull.

I think we could get the project crowd funded to pay for your time and knowledge by newbies like me who will actually use the info.

 

[DAG]

heres a question knowone has data to back up. How tru is true enough for driveline alignment? At what point does ware occur? If its tru in a static state is it true in a dynamic state? How do you true in a dynamic state? How much can motor mounts flex, how much can midshaft rubber flex, how much can the hull flex.

Hint: nothing is ever truly tru choo choo

know one, true, wear, true, true

It’s called common sense mechanical practice. I won’t blame the kids either. Gen x, y parenting is to blame in regards to idiot millennials. ThAnk god my dad is a baby boomer. Haaaaa

Hahaha yes of course, the Baby Boomers, the generation of entitlement that started the naming of generations in the first place. The first to assume they are owed a better life with time. The millenials of the 60s, and the reason kb's of info at a time are spent on self congratulatory posts like yours.

 

[circafwsk8r]

I’m 32 a millennial but raised by a baby boomer. Not the norm. I am aaaaaa lot dif that most people I know my age

A pwc is just like any machine. The truer the alignment, the smoother the machine will run.
Just because the driver (motor) is suspension mounted, does not mean you should not go to greater lengths to achieve as close to perfect alignmnet as possible.

Case in point, on a stock class race ski. Making a near perfect alignmnet yeilded a little over 200 rpm , over origional alignment, this translated into a national championship.

How about all the busted mounts, and mid shaft housings, and messed up shafts..... alignments reduce all these occurances. DAG, you specilize in analysis? Get to work! This is not that difficult to figure out.
Simple cause and effect!

Does the motor want to twist on the motor mounts? Am I better to align the mid shaft dead center or up and to the right?
