I'm currently rigging my control system (back at work after a 3 year     stop).

     

     just aligned everything last night and assembled loosely according     figure 3 but I have inside of WD-1011 a gap of at least 1/16" 

     [img]cid:part1.03050103.06050105(at)gmx.net[/img]

     

     I doubt I can get the AN3 bolts as tight to close that gap without     overtorquing them.

     Did other people face the same issue or was their WD-1011 a close     fit?

     

     Many thanks for your help!

     

     Cheers Werner

Werner: 

From the photo, it looks like the lower flange may be bent down a bit leaving the two flanges more open at the outer edge. See if they are parallel or does one angle away.

Thanks Byron, but that is only the angle under which the picture was 

done, bot flanges in the area where the bolts are passing through are 

pretty parallel. It's about 5/8" wide.



Cheers Werner

As with all such end bearings, you must capture the bearing so that there is no relative motion between the bearing itself and the mount or bolt (i.e. all motion is the bearing inside the race).  Add washers as needed to fill the gap and torque holding bolt.  Recommend having about equal washers on each side of the end bearing.  It is helpful to have both AN960-10 and AN960-10L washers to make the best fit.  Do not deform the weldment as you want the weldment faces to be parallel to prevent binding.

 

I use a piece of masking tape folded over the edge of the washer to help insert into tight spaces.  Many techniques and some special tools out there for this.

Is the same spacing evident on both sides of WD-1011L and WD-1011R? If all the same, spacing, I would think others have seen the same issue. It could be possible that one flange was a bit out of place during welding. I have heard of some others seeing that on a few occasions.

I don't recall any significant spacing issues (some a bit tight or loose but not a lot). They will move some during tightening. I would use a " sacrificial" nut and bolt to tighten and see how much movement takes place. That way if over torqued, just discard the bolt/nut. If needed, you could add additional washer inside which may facilitate a longer AN3 bolt.

I actually opted to go with the drilled bolts, castle nuts and cotter pins on all of the control surfaces.

I agree with Carl to use either AN960-10 or -10L washers to take up the slack. I will have to take a look at mine to see if I had any issue there.

 I have no notes in my construction plans of any issue there.



IF you want to improve on the self-locking AN365 nuts, suggest you go to the current standard for control systems, 

which is the MS17825 or MS17826 self locking castle nuts, so you have a belt and suspenders retention.



However, I know of no problems with the standard AN365 in Vans control systems.

I would be surprised if the gap didn't close when you torque the bolt. If it doesn't, just add an AN960-10 washer on the inside and either go with a longer bolt if necessary, or switch to an AN960-10L on the outside.

yes both the same



washers and a longer bolt would be an option. I've sent as well a 

message to Van's support to get their statement. I was just a bit 

surprised as otherwise the parts are fitting well. As this are the 

primary control parts I rather would not like to experiment.



Thanks for all the ideas coming

Werner,

Just went through the exact same issue  a few weeks ago.  I just used two of the smaller washers on the forward side of the rod end bearing and one on the aft end, all captured inside of the weldament.  I'm not even sure I had to use an "L" washer on the outside - and used the stock called for bolt.  Plenty of threads still remained.  Worked fine, no rubbing, no issues.  

You might consider using a larger O/D washer on the most fwd side,  so as to minimize the  fwd/aft movement of the push rod should the bearing separate from inside of the rod end - it is still captured inside of the welded sleeves no matter what. 

Although I think one could take up the slack by tightening the AN bolt/nut, this would undesirably stress the area (mounting sleeves) for no reason.   

Am going out to hanger today and will double check - any change I'll let you know....

Also, please let us know what Vans says.  Maybe they made some changes and we need to make some changes as well!

Thanks Rich,



I actually went along as Jesse said 1h ago, torqued with 25 in lbs and 

indeed it did close the gap and clamp all together, after the 2nd screw 

I had to retorque the 1st one a 2nd time.



This puts some bending on the flanges, I will wait to hear from Van's 

but think with that low pressure there is no harm, I was not expecting 

that I could close with that little torque the gap.



Cheers Werner
