r1150 Cam Chain Tensioner replacement and Test Ride

[@Psychalflare]

I know it's been almost 6 years, but I have the same rattling on my 1150 and it's been driving me crazy. Seeing your enthusiasm after getting the bike out again after doing the mod sold me--thanks!

Just to answer the question. Do to the right side being upside down. Fluid does not leak out do to gravity like left side does. This is the main reason you can get away with only one replacement. The new one has a hydraulic valve which keep unit charged for months at a time when not ridden. Old one leaks out minutes after sitting. If you still have noise. More than likely it is one or more of the valve push rods broken on the end. There are newer updated solid ones that will fit and not break like factory. The fellow referenced in this video "Cris". Has a Great Video about this issue too. Good Luck. And good to see well done videos for the "Do it yourselfers".

The left hand camchain tensioner were an issue because the oil drained out of them when stood particularly when on the side stand. The noise on start up disappears once the oil pressure once again builds up in the tensioner. The right hand one does not suffer from the same problem. A mod that is well worth doing.

It also can cause a rattle and pinging at 4-5000 rpm's. Also cause failure of the chain guide which can result in catastrophic engine failure.

[@robamkuijpers]

you are right , based on this article I changed the left cam chain extensioner. Cost about 50 euro but an enormeous improvement. You don;t need to do the right side, slightly different construction.

[@gregorywoo1276]

I had similar symptoms as you, my colleague, I did exactly the same and I got the same effect, thank you for the film, because it was the inspiration to act, thank you again and best regards 👍😎

[@tibork3845]

How about part #11 on the diagram? I don't yet know much about these bikes but that also looks like a tensioner. No need to replace that?

[@jimmurdoch6206]

Great video - love the enthusiasm, about to do the same mod myself.

[@frankdreja4824]

Found your Video Today ! Buy My on 1150 bevor 8 Weeks ! Hate This Noise , will change Next week THX

[@asturiancetorix2552]

I replaced that on my old 98´ R850RT, my engine didn´t have that clattering sound, but I thought it was wise to do it anyway.

[@mrmree]

Thanks for listing the flippin tools for the job.nice!

[@charlesfoster141]

How many miles did your bike cover prior to this maintenance?

[@Reginald-Erasmus]

Lol only warning from me, as a Bmw technician, when i work on the old models like lets say this one, always remove the injector before moving the throttle body, why? because that nice shiny looking pipe that goes to it becomes very hard and brittle from age and they snap with out warning. so use it, dont use it.

[@markrabone6584]

I put inox all over - then it slid in no worries… but I was extra careful after reading your post

[@cinematictrax8443]

music to the ears. Just ordered parts for same job on my GSA. Slange Var

[@loganconnally4361]

Doing this asap!! I was wondering what that noise was!!

[@sunyoungg5634]

Once the oil has filled the tensioner it is NOT compressible - the small ball check valve prevents the oil being displaced and of course the oil isn't compressible so the tensioner is solid at that point.

[@JohnDoe-bf1fw]

Great video. I see you used OEM parts and not the ones from the BeamerBoneYard. Has anyone tried the tensioner from BeamerBoneYard? I'm thinking it would be safer to pay more and go OEM. I need to do this on my R1100R with 130,000 miles. Hopefully the cam chain guide is not already damaged.

[@Danish-ADV]

Is this an original BMW part ? Or possible to find some where else ?

[@LOTPOR0402]

What about the other side ,do they not need to be upgraded ?

[@asturiancetorix2552]

The left side tensioner is upside down, so it lost it´s oil and it´s weaker until the engine runs and pump oil in it again. The right side it´s facing upwards, and it doesn´t lost it´s oil, and can put enough tension on the guide rail so the chain won´t slap it and broke it over time.

[@GeorgeXVX]

Great video. Thank you Armand5000. Does anyone know if the new hydraulic piston (#15) can be used with the old cylinder (#10)? Are the old one housing the spring cylinder and the new one housing the hydraylic piston the same dimensions? They look the same at about 04:00 of the video, but are they indeed the same?

[@lemmormiguel]

Is this upgraded tensioner ok for gs1250?

[@alpino7739]

Hello everyone. Thanks for this video. Could anyone put the link where i can buy the tensioner ? Thanks

[@TheSmartbear1]

It’s a genuine BMW part, your dealer will sell it.

[@Faraon10012]

Hello Armand!!!! Thanks for your video. I have the same engine. Id like to know your opinion about the sound of my motorbike, do you think it is the same problem? You can listen it throught the next video

[@mchabi18]

Good job. But you have changed only one of the two. See drawings. Thanks for the video.

[@piotrradwanski2507]

Typical issue with BMW boxer engines. Left tensioner is getting failure. Right side is basicaly ok.

[@herbie77]

why are you only changing the left tensioner? Whats up with the one on the right?

[@TheSmartbear1]

The r/h tensioner is inverted, because of this the oil doesn’t run out and cause the issue.

[@joseluislazzarofierro7846]

Goyo el me dice qué lo qué está roto son los patines plástico por donde pasa la cadena y que en BMW le dijeron que hay que sacar el motor

[@johnbridermanbmxmotocross5992]

[@daveh2068]
