Hi All, I changed the DOD Filter today [Saturday] and noticed that the lifters were a bit quieter, especially at idle.
Been for a few road tests and it is running quieter.
Very simple to do,
Items required -
Patience [Don't Rush it]
27mm 6point 1/2 drive Deep Socket [$18 at Bunning's]
1/2 drive universal
1/2 drive ratchet
1/2 drive Tension wrench recommended [to re-fit the pressure switch at 35nm]
Thread sealant [I used a little bit of Gasket Cement on the thread]
7mm long Allen Key as per image below [to remove the old OD Filter - have explain below]
Last but not least, replacement filter [that's if you wish to replace it]
- Inspect the area with a mirror, or similar [where I used my phone camera] so you know were you are working, most of it will need to be done by feel, as it is right down at the back of the motor below view.
- Remove the wiring loom by sliding the locking tab up, and pressing on the tab, and carefully remove the plug.
- Assemble the Ratchet, Universal and Deep Socket, and slide it down the back of the valley and remove the pressure switch, keeping in mind its a right hand tread.
- Use the 7mm Long Allen Key, and place into the top of old DOD Filter and press it in a little way say 5mm [don't press it in to far]
- While the Allen Key is in the old DOD filter, twist the DOD filter either way a little bit to loosen it,
- Then lift the old filter out of the housing, and it should come out attached to the Allen Key as per image below [as the Allen Key is the perfect size for a neat fit in the centre of the DOD Filter].
- Clean the work area as per image below [DOD filter housing area, careful not to let any dirt drop in the hole]
- If your re-using the old filter, clean it with de-greaser, wash it clean with water, and dry it off with compressed air.
- Re-fit the DOD Filter, best to use 3 fingers, one to locate the housing, the other two to hold the filter tight, [because you wont want to drop it behind the motor]
- Or, place the DOD filter on the Allen Key a little bit, locate the hole, and use the Allen Key to place it in the hole, then with one finger on the top of the DOD Filter, slide the Allen Key out.
- Grab the Allen Key and use that to make sure its all the way in by pressing down lightly on the top ridge of the filter.
- Clean the thread up on the pressure switch
- Apply thread sealer,
- And carefully manipulate the pressure switch back into the housing by hand [careful NOT to cross thread it] you will feel it screw into the thread, and keep screwing it in by hand.
- Then nip it up with the ratchet, or ratchet tension wrench. [to 35nm]
- Re-connect the plug, and slide the locking tab back into position.
There was one thing I did notice, it appeared that the stainless steel gauze/filter material was much finer on the old filter, than the replacement filter,
So the replacement filter will allow more oil pass through,
I am guessing it should quieten it down a bit with more oil available to the lifters.
I cleaned the old filter in degreaser, and have kept the old one, as its in still in good condition, and wasn't damaged when removed.
Total time taken approx. 1/2 hour. [for installing a new one]
