albamoto Can you please do the Wright up for removing the servo pump. I got my system working or so I thought but the brakes failed again and I had to travel 150 miles with little or no brakes to get the bike back home, not some thing I would like to repeat. Thanks in advance if you can do this.

Re: ABS Pump:- Removing it for Repair

Thanks for this info, i hope they have a solution for this.
The sleeves i found where only for bigger diameter.
The rod of this motor is only 5 mm.

Re: ABS Pump:- Removing it for Repair

SKF bearing company makes a product for this kind of thing. It is called a speedy sleeve. A very thing flanged tube that you slide on and glue in place with loctite. There are other brands and like you say motor replacement is possible. Ford Fiesta pump motors work.

Re: ABS Pump:- Removing it for Repair

Hello guys

Yesterday i finally got the time to assemble my abs units with new oil seal and o-rings.
Got it back in the bike, bled the system first manually to the abs units and then automatic (using the abs pump), went for a ride (without the tupperware). when i came back the leak was still there.

Got the abs units out again (went very smooth), opened it and noticed that the small rod of the motor is showing grooves (wear).
I think that is the reason of the leak.

So i think i have 3 options

1- looking for a replacement motor for the abs unit
2- try to repair the rods (glue-ing a hardened bush d5 - D7 on the rod and looking for a bigger oil seal)
3- bypass the abs

Does anyone have any suggestions?

Re: ABS Pump:- Removing it for Repair

My bad I had you mixed up with the guy in Belgium that was replacing leaking seals and o-rings on his unit. I did look at the BBA-Reman web site in the US and they listed several BMW units but not the LTs by part number so I may give them a call this week and see what they have to say in light of the UK office being able to repair them.
May 29th, 2019 5:46 pm
EezaK1200LT No the company who rebuilt the unit replaced some internal components.

All I did was remove it and replace with the addition of 5 new seals that they recommend on the hard lines.

Very happy to report it passed its MOT
Test today.

Don't be intimidated by the job. It was surprisingly easy and I suppose I should do a write up so am to encourage owners to get stuck in

Re: ABS Pump:- Removing it for Repair

Congrats but you did repair a leaking unit only since you you no other failure like a pressure sensor or actual pump motor (well I guess the fact you opened up a motor and got it back together is fantastic). But that does not diminish what you have accomplished - well done. Now if you could make up a good list of all the bits you used that would be a big help for the group here. Thanks in advance!

Re: ABS Pump:- Removing it for Repair

Ok so I had the day of work today and have finally fitted the repaired ABS module into the bike, Its Working better than ever. To say I am chuffed doesn't come close. I did have a bit of trouble with the electrical connection as I managed to bend a pin.

No matter it straightened out ok and i have now put it all back together.

So we have a repair for the ABS evo brake system.

Re: ABS Pump:- Removing it for Repair

Finally found the oil seals in EPDM for my ABS unit. I went all arround the world for them. They cost like gold since they are so special i guess (€60 a piece). Still a lot cheaper then a complete new pump.

Hopefully this will sove the leakage.

Keep in touch

It is an S-10 but you really don't need them if you buy the speed bleeder bag and hose. Hook up the hose and elevate the bag and open the bleeder and pump away. Any air bubbles will NOT travel down the hose so it makes it a one man operation. I have been doing this for years on the LT. The speed bleeder nipples have a thread sealing compound on the threads that make it difficult to move them and tell when they are fully seated. But their bag is fantastic and only $6.00 (last time I checked).

Re: ABS Pump:- Removing it for Repair

Module Masters fixed my iABS Teves.
But the iABS servo they are still unable to fix.
And they’d make a pretty penny on those too...

albamoto I hope you are correct about it being just low fluid levels. I am still waiting for the refurbished calipers to be returned.
But the good thing being able to get the servo unit refurbished at a reasonable cost if required. Hope to have it all back together some point next week.

Re: ABS Pump:- Removing it for Repair

If you lost fluid and the lights were flashing alternately, it may have just been low fluid level due to the caliper seal leak. If so you should be alright once you get it back together.

Thanks for sharing this info, It is very interesting, I currently may have ABS pump failure also, My left hand caliper seals went and I was luckily just stopping for fuel off the motorway when I felt the brake lever going a little soft, The abs warning started to flash and I managed to stop and after having a look around the bike noticed that there was brake fluid on the caliper and pipe fittings. I have stainless lines fitted so I am hoping that once I get the calipers refurbished I can bleed the system and all will be OK. If not then it looks like a phone call to this company for an ABS refurb. The cost seems quite reasonable. My bike is 2005 so should be same system. I would prefer to keep the servo system on the bike if possible.

Re: ABS Pump:- Removing it for Repair

OK thanks man, i’ll have a look at that website. I asked prices in France (WWW.Francejoint.fr) but no reply yet.

The O-rings should be easy to order in EPDM, it is the shaft seal i am concerned about. In most cases they only have them in NBR.

For the O-rings i've measurerd :

- O-ring @ bottom of soliniode : cord diameter is 2 mm innerdiameter 32.9 mm (2x needed) (2 in pic)
- O-ring @ bottom of ceramicpump : cord dia 1.5 mm inner diameter 8 mm (4x needed) (3 in pic)

- oil seal on shaft of motor : dia shaft is 5 mm dia housing 15 mm height is 5 or 6 mm

i'am having dificulties in finding the oil seals in EPDM. If anyone knows where and how, please leave a message.

Thanks
check out the O-ring store: https://www.theoringstore.com They have a really large selection of O-rings in all kinds of sizes in EPDM. They stock full sizes of metric - so you wont find a 38.8mm; but they will have a 39mm which I imagine is close enough: +0.2mm. I sourced larger O-rings for the oil filter on my K12RS to stop a leak due to either the cover or pan being off a bit.

The website is easy to use. Probably not the cheapest place, but they will very likely have what you need.

Looking forward to a good report from you. That was a great price ($311 US). Our cost would be higher with shipping from the states but I think this beats the other guys in Germany.

Re: ABS Pump:- Removing it for Repair

Ok my ABS pump is now back with me all repaired and new looking. BBA Reman have corrected the two issues they found with the unit and have sent it me back for a combined cost that includes the VAT at 20% and the return postage ...

That cost was £240

Ive got to put it back in and checks its all OK but I'm very happy with that kind of cost.....

Ill keep you appraised as it moves along.

For anyone who wants their details they are BBA Reman in the UK based in Rochester Kent and their contact details are 01634 687222

They have a global presence and so if you need them go to Home (GB) | BBA Reman

Re: ABS Pump:- Removing it for Repair

No the Battery tray can stay in situ. You will need to remove the module for the reverse drive though. A few fasteners and sadly you need to remove the cables to it. There's a big earth and also a live that goes straight to the battery.

You will need to un-clip a lot of the cable ties as the wires get in the way but it can be done... Once the abs hard lines are out just wiggle it upwards and the 4 pegs will come out of the rubber bushes in the tray. The ABS unit stays in its carrier that fold the top hard line

Take the batter out as it will give you more hand room. I also removed the fixing at the front of the battery tray as that allowed one of the hard lines more movement.

Re: ABS Pump:- Removing it for Repair

Hello Guys, My name is Jan and i'm a LT1200 2003 owner for about a year now.

Recently i found a few drips off brake fluid on the floor right under the abs unit. When i inspect the unit, i see oil on the outside of the 2 motors on the unit. Also have ABS and ! flashing on the dash.
I am going to remove the ABS Unit, screw it apart and put new o-rings in. i found a good tutorial for this on youtube. Unfortunently there is no info about the side and material of the new o-ring he has put in.
So i have two questions :
- are there any pics or procedures on this forum that shows how to remove the abs unit on an K1200LT 2003?
- does anyone knows what meterial the O-rong has to be in order to be compatible with the brake fluid.

BTW i learned already a lot reading all the stuff on this forum. Great job guys !!!

Many thanks
Apr 27th, 2019 9:17 am
EezaK1200LT The lines I bought in the UK were sourced directly from Venhill. I could not find spiegler lines in the UK.

There are two lines on the rear and 3 of the 4 fittings were not the same shape as the OE lines.

2 of the front 4 lines had different shaped fittings I.e the angle of the elbows etc.

The front left as you sit on the bike is 10-15mm too long and so pushes up the hard line into the bottom yoke so I will need to keep an eye on that.

Honestly they are OK but that's all they are.

I cannot recommend them and that does not make me happy.

Look at the end of the connector opposite the wires. You will see a small slot, place a flat blade screw driver in the slot and pull out ward with the driver. That part of the connector will slide out and jack the connector upward and off.

Re: ABS Pump:- Removing it for Repair

Ok after a lot of grunting and groaning the things finally out. I didn't realise the unit stays on the carrier. If Sombody looks at this in the future I had to pry under the pump against the frame as the unit is held by 4 pegs that slot into rubber gromits in the tray.

Right now I don't love this bike so I am looking forward to getting this sorted so I can learn to enjoy it all over again.

I'll keep you all appraised as the refurbishment continues, it's crazy but right now £25 in parts would bypass the abs altogether but in reality I've gotten used to the brakes and they do inspire confidence when two up.

Not so sure about a gravel car park mind.

I suppose as it's got so much of its clothes off I should change the fuel and air filters
Apr 25th, 2019 9:29 am
EezaK1200LT Ok this is a message to anyone who's taken the ABS pump out.

Firstly how did you get the electrical plug off the module (I don't want to damage it) and then how on earth did you get the whole thing out.

It feels like the pump is solid and I've removed all the fixings I can see.

I've taken the front fixing out and the top fixing that holds the transfer tube to the inner rearmost line.

It feels like its still fixed to the battery tray

I agree with the every year flush. I did mine last year and just changed it again and it was pretty dark for only one year. Florida humidity is not good for brake fluid!

I replaced the brake lines with Spiegler. They are of awesome quality, and they sell the exact kit for K12LT.
Hope you resolve the issue, or return them.

Almost afraid to change it. These things have a way to get broken if messed it. It’s jinxed.

Will change to yearly.

Re: ABS Pump:- Removing it for Repair

By now most folks realize the servo systems actually have 4 separate fluid systems. Each needs to be bled separately. But I do see posts where it seems this knowledge has not gotten to the owner. In a damp climate, every year, even though the manual says different.
