Replacing fuel filter and oil sight glass

Postby Dode4444 » Tue Sep 10, 2019 6:50 pm

Hi folks thought I’d make this a new post rather than adding more questions to my previous servicing one.

Fuel filter-

Can anyone please tell me if it’s a relatively simple job to replace the fuel filter on my 1150rt and I’ve heard there may be non reusable clips??? If this is true does anyone have the part numbers etc or where I can get them?


Oil sight glass-

Is this a serviceable item as in every couple of years or just when you have problems?
I think mine may be the original as I have no paperwork or history to suggest otherwise.

Thanks in advance.

George.

The job is straightforward to do if you have a Haynes/Clymer manual to guide you.
Before you start the job there are some things to consider:

1. Do you need to change the Fuel Filter? This is normally done every 24,000 miles. It has to be fitted in the correct direction of Fuel Flow as indicated by an arrow on the side of the filter - observe and note down the fitting direction of the existing filter before removing it.

2. The original Fuel Filter hose clips are called Oetiker clips and are for one-time use only.
The Oetiker clips can be opened by using a suitable sized flat screwdriver in the 'ear' and prising it open.
You can replace these Oetiker clips on the Injection Hosing with stainless re-usable Fuel Injection Hose Clamps size 13mm, Motorworks Part Number COA60928 - https://www.motorworks.co.uk/vlive/Shop ... rch=SEARCH
These clamps will also fit other areas using the same size 13mm Fuel Hose.

If replacing any in-tank Fuel Hose the specification MUST be for CONSTANT IMMERSION Fuel Injection fuel hose.

Depending on age/mileage, the internal fuel hose can deteriorate and become weakened leading to rupturing which causes a loss of fuel pressure and fuel supply failure.
For this reason, consider replacing all the internal 13mm fuel injection hosing particularly the 'U' bend hose on the Fuel Filter.
The 'U' bend hose is best replaced by the genuine BMW part (Motorworks, Motobins, James Sherlock).

3. You will likely need to replace the LARGE sealing O-ring fitted under the Fuel Pump Plate (on the inner RH front of the Fuel Tank) as this will have expanded and be impossible to refit correctly.
It can sometimes be re-used if left in the sun or on top of a radiator to shrink back.

4. The 2-pole connector from the cylindrical Fuel Sender (fitted on top RH front of the Fuel Tank) needs to be disconnected from the Fuel Pump Plate Fuel Arm Wiper Assembly in order to remove the plate completely - do NOT forget to reconnect this connector when re-assembling.
Be careful that the 2-pole connector cable does not foul the Float Arm (for the Low Fuel Switch) when re-assembling.

5. BEFORE disconnecting the hoses from the Fuel Pump Plate, label the External Fuel hoses and Vent/Drain hoses both on the hoses themselves with tape and on the Fuel Pump Plate (using a fine marker pen) so that you do not get them crossed.

LATER EDIT: Bazzer's post reminded me that your R1150RT will likely have Quickly Detachable (QD) Fuel Hose Connectors on the RH side of the Fuel Tank which will prevent you from crossing the Fuel Hoses (reversed male and female Flow/Return sections prevent this).
However, the original plastic QD Connectors can become quite brittle in time and the male 'nozzle' part can break off.
Be very careful when handling these Connectors.
You may wish to change these for the more reliable metal type because of this problem.



Oil sight glass-

Is this a serviceable item as in every couple of years or just when you have problems?
I think mine may be the original as I have no paperwork or history to suggest otherwise.

If it is not leaking then leave the Sight Glass alone or you could be in for a load of grief.
Inspecting for leakage at regular intervals is all the maintenance required.
Note that most leakage on the Sight Glass is caused by idling the engine without the bike moving so causing the oil and crankcase to overheat.
If the engine is left idling when parked up for too long a period, the excessive temperature and crankcase pressure can blow out the Oil Sight Glass on the early Oilheads causing catastrophic loss of oil and engine failure.
The moral is; do not let your Oilhead idle for very long before riding off!


Thanks in advance.

George.

Fuel filter - easy to replace (when you get there) you'll probably find its the one it left the factory with. Its held on with stupid one use only Oeteker clips which are easy to remove (if you have the right specialist i.e. expensive tool and technique). I replaced mine with nice easy fuel line clips (NOT JUBILEE !!!!!), dead cheap on Ebay. Replace the expensive "U" shaped fuel line while you're at it - damhik............
Oil sight glass - in theory easy (drain oil, spear it out, replace) usually it puts up a fight. I suggest when out meticulously clean the seal are, insert with a large socket on the outer edge (so placed in evenly and gently).
With the fuel filter the tank seal "O" ring can expand when removed. Just leave it in the sun for a while to contract back, and be very careful when fitting. If not you will find out when you fill up..........again damik !
Enjoy !

Oh yes, while you have the tank off, flush the brake and clutch lines.............

George,

If you are just starting to do your own DIY maintenance on your R1150RT then you will benefit by having the following RealOEM BMW Parts Fiche.
This Fiche allows you to obtain the correct BMW Part Number for every part of your bike.
It also allows you to see how parts are fitted together in the relevant diagrams.

Below is a link to the RealOEM BMW Parts Fiche - put the last 7 digits of your VIN into the 'Serial Number' box and select 'Search' - the result of the Search will be given at the bottom of the page and will identify that VIN.

Using your VIN in this way identifies the EXACT build of your bike and the appropriate Part Numbers.
The diagrams are also useful showing how the parts are incorporated in the assembly, however, note that the diagrams tend to be generic and may not be exact for your build although the Parts List will be:

From the VIN result, you can then go to the Parts Diagrams and get the correct BMW Part Number for every component of the bike.

Using the VIN number in this way means that ONLY the parts specific to that VIN will be listed in the Parts List below the diagrams and is the safest way to get the correct BMW parts for your bike:

http://www.realoem.com/bmw/select.do?kind=M&arch=0


I suggest that you get hold of a Haynes or Clymer manual for your bike as each contain a wealth of information and tips on maintaining and/or rebuilding a bike. They also contain Wiring Diagrams.

There are lots of experts on this forum who can help you out. It is better to post a query here beforehand than dive in regardless and maybe break something through lack of knowledge.

You can get new and used genuine BMW parts for your bike from:
Local BMW Dealer (new parts only) https://www.bmw-motorrad.co.uk/en/home.html#/filter-all
Motorworks https://www.motorworks.co.uk
Motobins (new parts only) https://www.motobins.co.uk
James Sherlock https://www.james-sherlock.co.uk

All above trusted suppliers and helpful with advice on purchases. The Motorworks website also accepts BMW Part Numbers (no spaces).

The correct socket tool for oil filter removal can be bought in Halfords for £8, so no need to puncture, chisel or hammer the filter to get it out.
