    Pulsar 150 Centrifugal oil filter cleaning

    This thread deals with the cleaning of the centrifugal oil filter of Bajaj pulsar DTS-i UG -4.5.
    As per the recommendations the centrifugal filter should be cleaned every 10,000 K.M.S.
    The centrifugal filter works on the action of centrifugal force on suspended impurities in the engine oil
    which is achieved by the rotating the engine oil in a chamber which pushes the impurities against
    the chamber wall,allowing the filtered oil to pass through it.

    Tools required:-

    * T-spanner (For clutch cover bolts)
    * Ring spanner (For removing the footpegs and kick lever)
    * Clutch cover gasket
    * Anabond gasket sealant

    Procedure
    - Wash the engine side thoroughly.
    - Drain the engine oil completely.
    - Before you attempt to open the clutch side please ensure you remove the footpeg, the brake lever and the kick.
    - Also remove the clutch cable and wiring to the starter motor.
    - Remove all the screws on the clutch side however leave the starter motor intact.It will come out along with the clutch cover.

    - This is how the engine will look after removing the clutch side.
    - Remove the oil pump by removing these screws from 1-3

    - Remove the clip on the base of the pump and take out the net cap.
    - Clean it with kerosene and a soft brush.
    - Now remove the screws 1-3 on the oil filter by engaging the bike in gear and holding the edge of the cap.

    - Now without removing it's gasket dip a soft brush in kerosene and gently wipe the chamber also clean the removed filter cap.
    - You will notice metal shavings inside. Continue this process till the chamber is free of metal shavings.

    - Now screw the cap of the filter back and make sure you don't damage the gasket or the screws.
    - Bolt back the oil pump and make sure it fits snugly inside and torque the bolts adequately.
    - Remove the old gasket and clean the clutch cover also as the lower portion will be having deposits.

    - Apply anabond over the edges of both cover and gasket and seat the gasket properly.
    Click image for larger version Name: DSC_0024.jpg Views: 1 Size: 91.7 KB ID: 1975339
    - Place the clutch cover properly and make sure the it covers the gasket and then lightly
    screw all the bolts from one end and check if it is seating properly.
    - Now tighten all the clutch cover bolts without over tightening it,it's a nightmare if one of the bolts slip.
    - Now put back the kick,footpeg and brake lever.
    - Fill the bike with engine oil and kick the bike several times before pressing the starter.
    - Look out for any leaks and make sure the bike is not leaking oil before taking it out.
    Precautions
    * Make sure the place is isolated from dust and pollution.
    * Do not attempt to start the bike while opening the clutch cover.
    * Keep away from the teeth and gears inside and don't place your fingers in between.
    * Keep the bike engaged in the first gear during the entire process and keep the bike on a level ground on the main stand.
    * After assembling the clutch cover fill it with engine oil and do not press the starter right away .
    Instead kick the bike a few times with the engine off and make sure that there is no obstruction while kicking or any abnormal sound.
    * For bikes not having a kick, shift to fifth gear and rotate the Tyre with your hands keeping the ignition off.
    * For all the bolts use ring spanners or T-spanners only and for opening the screws on the filter use good quality
    screw drivers preferably the multi-head type and choose which attachment fits the best.
    Compatibility
    * This method can be applied to all bajaj pulsar range except the 135-LS & the 200-NS(the filter cover is provided independently on the clutch side).
    * For oil cooled bikes 200dts-i & 220dts-i/fi you can remove the banjo bolts of the oil cooler and take out the clutch cover.
    * If your bike is having rear sets then there no need to remove the footpegs.

    And finally-- I am not responsible for any damage to person or vehicle by this procedure(Standard Policy )

      How often does this procedure needs to be done ( x kms on odometer?)

        Well this depends on following factors

        1. Very bad engine oil / desi variety : Lot of burnt oil sediments will settle down and viscous/gummy layer will be seen on wall of the cover. Though this viscous layer is necessary for lubrication/heat transfer etc, it will start to attract carbon deposits as time goes by.

        2. Oil filter/pump is kaput : All particles will be sedimented and will need this level of cleaning.

        3. Extensive run period : Guys who run their bikes upto 5K or 10K in their ODO without oil change, might need this type of cleaning if they care.

        4. Clutch plate change / post new piston or rings : This is much needed especially for those who are going to change engine oil post run-in period, and for those who have changed bore/piston/rings recently cause metal shavings will be present and needs to be cleaned.

        I will be an good example for point 4. I'm going to change my clutch plates/piston/rings/decarbonization. After which will allow the bike to run for 500 kms with same engine oil, then do this type of cleaning. The primary factor is that if we (Bajaj owners) had the same type of facilities such as TVS/Yamaha for changing oil filters, then this level of work might not be needed for a very looooong time. But since the type of cleaning is centrifugal and extensive man work hours is needed for opening and closing the parts, its a weekend task.

          Well well, I would not trust the SVC guys to do a thorough job such as this one. I rarely have ever come across mechanics who bother to look for things that may need attention and inform before hand to the owner. Thanks for the very informative post. I would be grateful if you could share any details on the way to decarb a four stroke engine as well.

            @prith thanks man for elaborating this further ...
            It definitely needs to be done after block-piston change

            Manual also suggests it cleaning at first service
            Which is around 700 k.m.s for pulsar
            If your mechanic skipped it on the first service
            Don't panic just get it cleaned in the next service
            If he is reluctant to do it
            Just show him your owner's manual
            It is mentioned in the service checklist to clean it on the first service
            And every 10,000 kms thereafter.
            However if you are doing oil changes properly as per recommended intervals
            Then i think the cleaning period of the filter may be extended to 15,000kms

            And i'm sorry i couldn't take pics during each step as I was doing this job solo
            It was very difficult to hold my phone while my hands were smeared in oil
            Well I guess I compensated that with a clear writeup

              Great and informative thread.
              But I do have one doubt, removing the oil cooler pipes from the 220 , which tool must be used ? More over, i couldn't get a clear picture how you removed the oil pump. The clip, also, is it reusable or just one time use and throw type. Would certainly love to try this out. But haven't removed the footpegs yet. And I think the last time my oil filter was cleaned was about 13k back.

              Cheers

                Yeah i think you are right, a regular ring spanner would not fit in the tight space between the two banjo bolts.
                However you can try T-spanner 12mm size, the attachments of most T spanners are slim as compared to regular ring spanners.

                For removing the oil pump you just have to remove the three screws in the pic, nothing more..
                Yes the clip is reusable, it is just used for holding the filter net of the oil pump at the bottom.

                If your bike is having rear-sets(being a 220 it must) then there is no need to remove the footpegs,you just have to remove the brake pedal.

                  Allen keys mate! They are over sized. I remember teh PBK guys using a ratchet setup, but it is more or less an allen key.

                  Once upon a time, a guy asked a girl 'Will you marry me?'
                  The girl said, 'NO!'


                  And the guy lived happily ever after and rode motorcycles and watched sport on a big screen TV, went fishing and surfing, and played golf a lot, and drank beer and scotch and had tons of money in the bank and left the toilet seat up and farted whenever he wanted.

                    I was going to do it this servicing but then I discovered I forgot to buy a new gasket from bajaj. Now skipping it for next servicing.
