Posted: Tue Nov 24, 2015 2:02 pm Post subject: Heavy Duty Gas Struts

I installed my gas struts last night and the doors hold open just fine, however they slowly descend if you let go from midway open, and that's before any upholstery is installed.



I have the center cam latch, flush door handle and keyed lock fitted, so there's some additional weight beyond the standard Vans installation.



Should I just use the standard Vans gas struts until they fail completely or install the heavier duty gas struts?



The heavier duty Vans gas struts retail for US$131.00, however is there an alternative source for the heavier duty gas struts at a reduced cost please?



Kind regards to all, progress at last with the fibreglass, woo hoo.



Warm regards

I have the stock struts and they have worked just fine for over three year

now with no signs of deterioration.  I have the cam latch as well, but the

rest of the door is stock.

I managed to break the plastic clevis on one of the Vans supplied gas struts.  The stroke of the standard gas struts is too long, at least for my plane making them very difficult to install without unbolting the doors.  

I bought two replacements from Bansbach.com in Florida with machined aluminum clevises, a shorter stroke and 580 newtons force or 130 lbs force, which is only 5 lbs lower than Vans heavy duty struts.  They are much easier to install because the stroke matched my open door pin-to-pin gap and a little higher force than Vans standard.  Plus, the aluminum clevises seem more "aircraft-like".  Here is what I bought:





- A1 M8 Hinge Eye End Fitting on one end

- A2 M8 Hinge Eye End Fitting on other end

- B0N0F50-100-247/XXXN Gas Spring 4"(100mm) Stroke 10"(247mm) Extended Length with 580 newton force

Total Cost, including both end fittings was less than $40 each

I recently bought replacement struts       from Bansbach as well.Â  The original Vans struts still worked but       one door started coming down if the wind hit it wrong.Â  I have a       flush latch, aftermarket center cam, lock, upholstery, etc - not       light.

       

       On 3/9/15 I purchased (2) A1A1F50-100-287/600NÂ  10017y1 struts for       $51.89 plus $19.27 S&H.

       

       They installed easily (i.e. throw seemed to exactly fit what was       needed - no compression required.

       

       They now work just right in all respects.Â  

       

       Just another data point.

I appreciate this thread as after 7 years my struts are starting so show some weakness.  I have stock doors with light upholstery, would the struts mentioned below be too strong?

Thanks,

Marcus

I mentioned this same issue earlier. I       need to contact Bansbach still. Anyway, the issue of "too strong"       a strut would be a non-issue if it was damped upon fully open.

       

       Nearly every new car with a door strut seems to do this, instead       of trying to yank the door off its hinges. Thus, you would think       they would be perfect for us. I have to use the regular strut       because my door is light and the HD strut wants to destroy the       door.

My struts seem to be falling more each month. It's tolerable but also a sign of needing to plan. I have been wanting to call vans beach as well and determine which we need. I need that damper on both up and down. When I get back I'll see what the reference was to the one that did work that someone sent me and see what the comparable one is with dampening from bansbach support.

Nice. i got a call back from a Bansbach engineer. He told me that the 5 

in A1A1F50 indicates "normal" speed and normal damping on the last 10mm 

of stroke. Damping only works if the rod is pointed down on full extension.



Bill, can you confirm whether you can observe the above? IE, can you 

observe that the strut slows down in the last 10mm of full extension?

I may have missed the response to Marcus question. I too have a lighter  door . Does anyone know what the pressure is for the Vans standard strut? I  believe the high pressure (580N) one will exert too much pressure on the door  when opened and closed.

 Thanks!

I wasn't even finished with the door       and my original Vans struts wouldn't hold the door open when I put       in the glass.  I bought the 600N struts from Barnsbach and am       happy with them.  They do have some pressure on the hinge when       open.  If you're going to have a strap to pull the door down then       you can just use the strap to let the door open slowly.  Or, you       can lengthen the 'guide' that places the attach point on the door       a little lower.

With the stroke and length I ordered from Bansbach, the strut is at full open stroke just when the hinges run out of travel.  The struts supplied by Vans are too long for the application.  If you calculate the full open length including the Bansbach clevises correctly, there will be virtually no load on the hinges.  Then you can have any open force you want without over-stressing the hinges.

I broke the cheap plastic clevis trying to compress the Vans strut so that I could install it without unbolting the door.  I do not recall exactly, but I think the Vans struts are at least an inch too long.  The Vans struts apply continuous pressure to the hinges and doors when open. Also, if they have end of stroke cushions, they never can work anyway.

The Bansback engineer appears to be correct.

As soon as I saw this today, I ran down and flipped one of my struts so 

that the rod end is pointed down.  It not only damps on the last part of 

the extension stroke but it seems to work a bit better at the compressed 

end of the stroke - it tends not to slam down if the door is let go.

This was news to me.  Thanks for the tip!

Fact is, I wasn't overly concerned about the way they opened but I was 

cautioning passenger not to just let go of the strap when opening.  Now 

they can just let it go.

 Bill, can you confirm whether you can observe the above? IE, can you 

 observe that the strut slows down in the last 10mm of full extension?

Bill... that is good news. thanks for checking. Vans has you install the 

opposite way with rod end up when the door is open. I will be ordering soon.



The issues are explained very well on this FAQ page.

 The Bansback engineer appears to be correct.



 As soon as I saw this today, I ran down and flipped one of my struts 

 so that the rod end is pointed down.  It not only damps on the last 

 part of the extension stroke but it seems to work a bit better at the 

 compressed end of the stroke - it tends not to slam down if the door 

 is let go.

Bill 



I enquired with Banbasch to purchase the gas struts and in their infinite wisdom, referred me to the Australian distributor here downunder.



Could you please confirm that you purchased (2) A1A1F50-100-287/600N  10017y1 struts for US$51.89 plus US$19.27 S&H, as I've been quoted AU$166.65 + 15% Goods and Services Tax + AU$15 freight.



Anyone interested in sending me across a pair of the heavy duty gas struts if I send you the money?



Kind regards

Warm regards



Patrick

Not that bad Patrick.  It was US$51.89       each plus S&H.  The total bill was US$123.05 with no       tax.  Close enough I'd say.

Patrick;

Stand by for now. I called and was told I needed to go to Grainger (US 

distributor) for the struts, than tried again via a "chat" and discovered 

that if I ordered it the way Hoppe did:

- A1 M8 Hinge Eye End Fitting on one end

- A2 M8 Hinge Eye End Fitting on other end

- B0N0F50-100-247/XXXN Gas Spring 4"(100mm) Stroke 10"(247mm) Extended 

Length with 580 newton force



They will allow one to purchase directly.

I ask that you stand by as it has taken 3 days to get that one person to 

take my order!!

I hope to get it done today, if it works I'll see if I can order the parts 

for you, or have the engineer tell me how to send to Australia.

So we have 3 different lengths now (and forces):



Bruce Hoppe

A1 M8 Hinge Eye End Fitting on one end

A2 M8 Hinge Eye End Fitting on other end

B0N0F5O-100-247/XXXN Gas Spring 4"(100mm) Stroke 10"(247mm) Extended 

Length with 580 newton force less then 40$ each what did you pay for the 

fittings?



Bill Watson

A1A1F5O-100-287/600N  10017y1 struts for $51.89 plus $19.27 S&H



Linn Walters

E2A1F5O-100-290/600N



denominations, the first 4 letter/numbers are the 2 Eyelets



     -A1 is width of the eyelet 10mm, for an M8 screw (8.2mm) length to 

the center 20mm/16mm

     -A2 is width of the eyelet 18mm, for an M8 screw (8.2mm) length to 

the center 25mm/NA

     -B0/N0 is none (that is why Bruce did order them separate (and 

maybe why his strut shows 40mm less?)

     -E2 is width 5mm (same as Van's), for an M8 screw (8.2mm) length to 

the center 23mm/16mm (why Linns strut is 3 mm longer then Bills?)



      F5O this is a normal strut vent in the end of the cylinder, strong 

dampening on the end, rod is 8mm, cylinder is 19mm

     -100 distance the shaft moves 100mm/4"

     -247/287/290 this is the mounting length center to center of the 

eyelets (or length of the assembly without thread length) (Van's has 

about 297 in my kit)

      /XXX force in Newton



So I assume Bruce assembly length being around the same then Bills and 

Linn's is 3mm more.



Bruce why did you choose that 18mm width eyelet on one side and Linn you 

the 5mm width; anywhere this givens an advantage?

I would add the 2 from Vans as well.



Not sure on the specifics on the 500N one. The 600N "HD" version is 

Stabilus, Lift-O-Mat part number 2218LP.



I have installed the Vans versions rod up, rod down, etc. No difference. 

As far as i can tell, no damping on either end. I have no idea why they 

would carry a non-damping version.



If anyone has another data point on damping on their versions, it would 

be great to hear. I do have a light stock door without upholstery, a 

center cam, etc.

Werner;

I had the same question on the ends, but here is the response from Bansbach 

on the difference between Bruce and Bill struts:

The 10017 (B0N0F5O-100-247/100) is the base part. We complete this assembly 

by putting in the A1 fittings (Item 96102)  and adjusting the force to make 

the final part A1A1F50-100-287/XXXN. There is cost for the change of force 

so the 100N could be anything you want including the 580N you requested. 

Same with the fittings.

I reversed my gas springs this morning to be installed rod down as recommended by Bansbach.  I now have cushioning at the end of the opening stroke.  With the rod end connected to the door as specified by Vans, there is no cushioning at the end of the opening stroke.  It is noticeably better.



Also, with the stroke length I ordered, I was able to remove and reinstall the gas springs without a problem because the door hinges are not quite at the end of their travel when the gas spring is fully extended.  Consequently, the hinges are not seeing a load exerted by the gas spring when the doors are fully open as was the case with the Vans supplied unit.



With the 130 lbs/580 newton gas spring, my doors stay shut until they are opened 3 to 5 inches (I did not measure it) and then they will lift open on their own.
