Cruiser Lean: "You've been doing it all wrong. Yes you"

[KY Longhunter]

My KDSS shutter valves are rusted shut! Broke a allen wrench trying to open them.

Can I use a little heat in this area?

Any suggestions.

Did you soak them with PB blaster

 

[KY Longhunter]

Headed home now to remove cover and try again. I did not try any lube

Look back through my threads. Toyota replaced mine under warranty because mine were rusted shut.
I hope you have the extended warranty??
Everyone must put some marine grease on these to keep them from rusting as they are not protected with paint or any undercoating.

Here is a LIVE shot of my KDSS valves

Thinking of heating and then cooling quickly to real the rust with FREEZE & RELEASE

On blast, liquid wrench and reapply a few times. Give it 24 hours to soak in.

You bigger problem is getting the broken Allen wrench out. Do you have a plan for that??

You can see the broken wrench in mine on the right side. I didn't do this so I assumed it came from the factory this way. Toyota swapped out the whole valve under warranty. Took 2 weeks! $2500 job.

I applied marine grease to mine. Need to do it again. Here a pic I just took.

Luckily the Allen wrench didn't break off in the bolt, it just broke at the L.

also, squirting PB Blaster upside down and it dripping in my eye seems counterintuitive.

Putting your head directly below what you're squirting at also seems counterintuitive ... just sayin'

You're lucky. Lots of penetrating oil on there to loosen things up.
Try some KY too if others don't work.

 

[KY Longhunter]

KY Jelly?

 

[Willy beamin]

This could go so many ways right now.

 

[MScruiser]

KY Jelly?

Astroglide is waaaaay better

So just to update this thread after driving my cruiser for the past 6 months or so using the method I proposed in the Original Post: This way of minimizing Cruiser Lean DOES work, and appears to be a long-term solution.



Carry on.

I like that you thought to re-visit for confirmation. You just game me something to fiddle with this weekend.

By no means an expert, I got a 2015 after my 2013 was totaled and after two weeks I noticed this thing is just off. It looks funny and isn't driving as well as the other. Read up on it and went and measured. Left front low by 24mm. NOOOOO!

The dealer agreed and ordered everything they would need to complete all the steps in the TSB (link at top.)

It took them two days as the service bulletin steps are pretty involved and a ton of sweat. Picked it up and it still has 14mm lean, within spec.

Three days later, I can't even measure a difference. The combination of repressurization and time was the fix. The dealer speculates there were several small air pockets in the KDSS. KDSS is genius and a bit spooky. The techs that worked on mine had no idea how it works, but the TSB is very specific on how to cure lean. I spoke with two of the pros at Slee, and they said I was welcome to bring it in but they would simply execute the TSB steps and then charge me.

I wouldn't be comfortable with spacers considering that KDSS relies on the symmetry of many moving parts to be effective. In particular I woul be concerned about spacers creating an artifact where the entire engineered system compensates for the spacers; creating performance uncertainty (safe handling at speed?). It might be a better choice to keep pushing for a root cause solution.

Good luck!

Do you have another way to link the tsb? The link ends up on a 404 error page.
Thanks.

I tried this method and could not get the 200 to lift the way I needed it too so I tried something else. I opened the 2 valves and left them open for 20 minutes then shook the vehicle as much as I could on the ground. Let it set for 20 minutes more and measured. No change in measurements. Went to the driver side and jacked it up from the lower control arm till the wheel was off the ground and dropped the jack down as fast as it would go. Did this a couple of times and remeasured. Saw a little difference. Did this a couple of times and let it rest again. The valves are open this whole time. Got some help to rock the 200 back and forth vigorously and remeasured. got the front within 1/8" of each other. Front end looks fairly even now. Before you could really tell it was leaning to one side.
