Re: Electro-hydraulic center stand - motor issue

Have flushed the ehcs, and refilled it with new oil. Is it possible to overfill the kit only with flushing? I put a plastic bottle over the filling hole (the one with a spring and ball) and opened up the 3 screws, from left to right, one at the time. I filled every hole until it came out new oil and no bubbles. I'm not sure about the exact amount of oil because I had to get out all the air. Can I have overfilled it, or is it not possible the way I did it? I just mounted the new motor today and at first the piston did not work, then I did as described above, then the piston got working when I connected it to a car battery. Have not put it back on the bike because I'm afraid that a heavier load may cause the unit to crash if I have overfilled it. Is this something I have to be worried about? PS! I hope all you understand what I mean, I'm not an English spoken person :-)

Re: Electro-hydraulic center stand - motor issue

Hello Gentlemen,

I back again on this tread.
after fixing the motor last winter, I have now to fix he seals. the unit is leaking oil.

Does anyone can provide me the contact where to buy the o-ring seal to rebuilt the unit?

Z,
No real problem, I was one that had a casing break on a fluid change & managed to repair it. I was just looking at your repair & thought it was another great idea & maybe something I would do if I had the need too at a later date.
Thanks Again.

you can modify the casing by cutting the portruding tip and installing a ballbearing and a cover that will let the dynamo axel rotate with no more friction (requires some machining...)

Re: Electro-hydraulic center stand - motor issue

Hello guys,

after having followed Ari procedure, I was able to get the ehcs back in order.
at the end the issue was the motor being dirty and a low oil level.

A BIG THANK to all of you for this wonderful post.bowdownbowdown:

Re: Electro-hydraulic center stand - motor issue

Hello gentlemen,

I'm a new member and as you may notice not an english native speaker. (froggy's)
I 'm the proudowner of a 2005 LT with 19500miles.
since today I have an issue with the center stand.
when pressing the button, the light is flashing, but nothing happen no motor noise.
then I checked the fuses, they are goods. the next step will be to check the motor using what Ari have done as document with some pictures to explain this.
This might save me a trip to my dear dealer. by the way they are very good and very friendly always there to help.

if you see anything else i should test before dismounting the ehcs unit ?

once again thank you for any tips you can provide.

Best regards

Stephane

Andy, if you have to buy a new unit, split apart the motor and pump parts as spares, and let us all know. I had a problem with the Marzocchi pump on mine when putting it back together where it locked up unless I put extra "spacing" between the blocks. Used some paper to make new extra gaskets, now it seems to work fine, I just don't know why it needed it and it could cause a problem down the track.

BTW, last time I pulled my EHCS off the bike I recorded a clip of the procedure because the original instructions weren't clear on how much tupperware came off.... tis HERE if its of use to anyone in the future.

Acquired them from BMW technical dept direct. I have a contact there. I wish I had found out about this first
Not Joes' fault, as it is at owners risk, but to fill to a max of 150 ml, you need to do the procedure as Joe did through the relief valve but with the resrevoir cap off to a max of 150 ml. It should then run perfect and have a 25ml expansion gap. When I filled mine it worked fine until yesterday when I rode it at 30 c ambient and the reservoir exploded whilst riding along, all all over the back wheel etc..
Still awaiting the result of a possible repair, if not then a deep breath and over Ł600 GBP

Re: Electro-hydraulic center stand - motor issue

I went ahead and put a "revision" on my earlier write up. Wish I knew the max volume allowable when i first tried it.

Anyway, I'm trying to upload the revised file now and I'll probably need help replacing the one on the server.

Re: Electro-hydraulic center stand - motor issue

Hi,
thanks for the replies reference the cracked actuator body. Unfortunately, the crack extends across the face of the actuator to piston large o-ring, not just across the top of the actuator, so it leaks when under pressure. I have a good mechanic looking at a possible repair to the seal face - if not then a new actuator is Ł600 GBP!!!!!!!!!!!!

Out of interest, the BMW specified volume is 125-150ml MAX!!! with a total capacity of 175ml. The flushing procedure on here is wrong and if adhered to as I and others have WILL result in a cracked actuator body,

I too blew the o-ring out of the main body by putting too much fluid in. I did not crack the housing. Since the housing is not normally under pressure (unless too much fluid is in it) you can take it apart and clean it up and seal it with some JB weld epoxy. Let it cure then re-fill but not all the way as indicated in the directions. Leave some air in the body. Bench run the unit horizontally and keep adding a little fluid until it goes the full travel. Then add a little fluid and run until you can hear the relief valve open (distinct sound change following full travel stop). You know it when you hear it. Then you should be good to go. Mine has held up for two years now with no leaks.

I did the same thing last year & if you look at this thread & attached file is what I did. It has worked ever since & I use the EHCS with the SO sitting on the back as she has a torn ACL & can't get off any other way.

Re: Electro-hydraulic center stand - motor issue

.and another little note to add to the procedures for this.

The EHCS actuator unit, (not the centre stand though), can be removed without taking any tupperware off the bike! and it only takes 15 minutes to remove.
Its 5 bolts and a nut, plus 1 electrical clip.

The electrical clip was hardest to get to, but even so a very small flat screwdriver popped that easily enough. Just under the drivers right footpeg.
Then its just:
1. nut on end of actuator rod (10mm & 9mm (?) spanners)
2. The bolt that goes through centre support between the 2 x bolts that hold the rear end of actuator (allen key)
3. The 2 x bolts that hold the rear end of actuator (allen key)
4. The 2 x small side bolts that hold the front of the actuator unit to the frame supports, one either side of the bike frame.

Slide the actuator unit out, complete with skid plate, ready to work on.
Oh, and a 35mm film cannister (the little black plastic ones) makes a perfect slip-on cover to protect the electrical connection on the bike while the actuator is out.

Mine will be out again for another couple of weeks while I try to find the seals.

cheers

Re: Electro-hydraulic center stand - motor issue

a little update...
My EHCS has started failing again, but I'm pretty sure its because I've lost a little too much oil because I didn't replace the seals with new ones... seems a bit hard to locally find the ones Joe listed in his writeup....
4) Rod Seal Part # “UC10x16x4.5U/MA30” Buna-N (mine was Urethane—Get Buna-N)
5) Wiper Seal Part Number “WP10x16x2.6x3.6/5U/A47” Buna-N )

I'll just have to a look a bit harder, unless someones got a US contact that I could get them through.... (just noticed Joe listed one also... guess I'll email them)
In the meantime I'll have to rip it out and top it up again, that should only take about an hour or 2 this time I hope.

Happened to have a look at the EMS-global site, and they no longer have the starter motor listed... however...
seems they also have an online site and have listed the same motor here
http://cgi.ebay.com/ebaymotors/NEW-S...-/360263643295 as a replacement for the HS-50N, if anyone is looking..... US$37.95 for the motor... and US$32.35 for USPS!!!

Upon dis assembly following Ari's instructions I found a stuck brush,
filed down some new brushes, soldered them in and it worked.

Felt really proud and did a little post on how easy it was.

A week later it stopped working, took it apart several times got it working,
put it back on the bike and it wouldn't work,
repeat that a couple of times and I was pretty frustrated.

Walked away from it for a couple of days and when I got back to it,
I discovered (by accident) the screw that grounds the brush was corroded,
there was continuity but apparently not enough to power the motor,
haven't had any problems since.

And on a side note the motor "sounds" different (quieter) than it used to.
Hope this may help someone!
This thread is getting long so I will start another on an preventative measure that can be done to prevent the motor failure.
I just had mine replaced under my Pinnacle warranty and kept the old one, took it apart, mild corrosion BUT the brush GROUNDING screw used in the motor is fine thread steel, the housing pot-metal aluminum.
Perfect combination for galvanic corrosion, steel, aluminum, electrical, & moisture!
Took the screw out and replaced with a stainless steel screw an washers and a touch of never seize.
Works great.
Took the NEW motor off (easy, 1 plug, 2 allen bolts) and did the same. Much easier because I did not pull the rotor, just took the case off while holding the spline end with soft jaw vise-grips (the magnets want to keep the rotor with the case housing when you pull it off).
Pulled off the brush grounding screw and replaced with stainless steel. The second screw just holds the plastic brush retainer in place.
I lubricated up the rubber seals and o ring (be sure to place o ring on motor assembly first) and re-assembled.
I am confident it last MUCH longer now!

Re: Electro-hydraulic center stand - motor issue

a little more info... local dealer for Marzocchi tells me he has a minimum order of 6 units from factory, so it would be really expensive and take forever.. and he originally couldn't work out which pump it would be from the markings (so, I'm officially stating that Woolly is a wizard at this research thing! )

Re: Electro-hydraulic center stand - motor issue

Chris,

glad to hear you got your problem sorted out! I did not want to add confusion to the oil fill discussion with my comments since I must have been plain lucky with my own oil fill procedure. I simply tried to fill in as much oil as I drained out...

And Wolly's findings about the source for the spare motor and pump are very valuable for the future use.

BTW I'll be meeting Tom & Hartmut in two weeks. I guess they will have some stories to tell about their journey around your continent...

Re: Electro-hydraulic center stand - motor issue

Great news. If you get a price for the pump, could you post it up here - the enquiry form on the US link I posted does not work (with firefox anyway).

Now all we need is a part number for the cylinder/actuator and we can rebuild with new parts without paying BMW prices

Re: Electro-hydraulic center stand - motor issue

Woo-hoo!
Just read through posts (thanks guys) but have already spent the morning back under the bike.... thought maybe I hadn't quite got enough oil in it after reading joegottbergs notes again last night...
I force-filled oil (using Shell Tellus 46) through the 3 small screw holes on the barrel sides (shown in Joe's notes) until it came back out, and now the bike comes straight up, no hesitation. It only needed another 20-30 mls or so.
I will have to watch to carefully over the next while to see if there are any leaks from the old seals, or if my paper gaskets give any problems... guess I'll know soon enough when it starts hesitating to lift again.
But for now, one happy lad!

Once again, this site is an amazing resource. Thanks again everyone!
(ps. Woolly, I'll check that pump out just in case!)

note: Woolly, yes that looks like its the right pump all right.
I've sent an email off to the Australian distributor too see if available and what they cost.. again it might be cheaper to buy from US and get posted out, if I find I need one.

Overall cost saving thanks to the generosity of eveyone here... about Au$2000

Thanks for the feedback.
-What type of hydr. oil are you using, it must be a non foaming type light in weight someone may know the grade
-when trying to lift the bike does the motor stall or continue to operate? IMPORTANT
-operating= air in hydr., dirt or a bypass failing- operate the ram several times to bleed the air
-TO MUCH OIL IS NOT GOOD!

Re: Electro-hydraulic center stand - motor issue

On filling. I over filled mine and blew out the 0.030" o-ring case seal. I repaired that and let some fluid out. Then I filled through the one small port at the bottom (see joegottbergs write up and Ari's pic #38) and ran it on the bench until I got full travel of the ram. Put it on the bike and it would not fully raise the bike. Pulled it off and added a bit more fluid twice until I could hear the relief valve open (you will know the difference when you hear it) when the ram was fully retracted. Put it back on the bike and all is well. Don't give up until you do that.

Re: Electro-hydraulic center stand - motor issue

Pleased to see the motor is good. As for the pump - being a gear pump, the tolerances are critical. Any wear in the gears or the 'side plates' will allow the pump to 'stall' under load.Again, it will be a standard pump - if you can post detailed pics, and any numbers etc. cast into it, and some dimensions, I should be able to source one for you.

SJ, yep, it arrived on Monday, and for all intents and purposes, looks to be identical. The sprocket/cog on the armature is perhaps a gnats whisker longer, but that wont be an issue.
Unfortunately I wont get to play at putting it all back together until the weekend... at which time I'll have to try to work out why the oil pump wouldn't go back together nicely again...
anyway, I'll update when I get some results one way or the other.
But as far as the motor goes, I think we are good (fingers crossed)

here's my old one I just got back.. some very minor differences compared to pic of new one.. (ignore the lighting, the top is grey cast aluminium also) checked the teeth/hole specs too.. they seem to match.

Got 3 x email responses overnight from EMS Global saying they had shipped.
Paypal payment was fine.

thanks again Woolly!
I'm 99.98% certain (that's the best you get in astro physics - nothing is certain) it will work without a problem - after all, it's only a (commonly used) electric motor. Keep us posted.

Re: Electro-hydraulic center stand - motor issue

Just a quick thought, if you change the relationship between the Field Magnets & the brushes by rotating the cover 180 degrees the motor will run backwards.. Too late by now but mark the cover (holds magnets) to motor end bell relationship when disassembling with a felt pen.
