Oil return pick-up tube.
« on: 09.03. 2017 20:04 »
 Mine is either bent, or the sump plate and strainer I got from SRM is made different.

 How fragile is this tube, is it likely to snap right off?

 Or am I better off modifying the strainers to get the pick-up to poke through?

I had the same problem on the plunger. The PO had solved it by enlarging the hole in the strainer.
I didn't like that solution so I bought a new one which didn't fit either so I took a deep breath and a pair of flat jaw pliers and managed to bend the pipe to fit the hole. Mind you, it was only about 2 or 3 mm out.
But don't hold me responsible if you try the same and end up breaking it off...  *problem*

 Morris,

 Mine is out a lot. If you were worried about a couple millimeters, I need to be complete frozen with fear *eek*

 Let me see if I can get a picture posted.

 If these show up, mine is way off.

 Looking at the strainer, it actually does not seem bent. Maybe its pushed in a little, but certainly not that much.

 I tried flipping it this way and that, no joy.

 Its either bend it, or butcher it.

Sums it all up!

I used this type of strainer which is a bit more difficult to cut out;

HI All,
The pickup pipe is pressed into the crankcase
The bend relatively easily, but do not just try to bend the bottom end of the tube,
Lever the pipe higher up,
With a dismantled engine I have heated up the case and moved the pipe in the alloy

Unfortunately the suction pipe is easily knocked when the crankcases are rolling around on the bench or garage floor. Nobody here would treat them like that but you can bet they've been falling off a shelf in a shed many years ago when they were virtually worthless. Also it is important that the suction pipe is not loosened in the crankcase half as it will suck air at the joint rather than oil, a reason why some A10's seem to fill up with oil..... anyway, I digress. The best solution I've found to adjusting the alignment of the sump screen is to slightly enlarge the holes in the corners to provide a bit of 'wriggle room'.

 Morris,

 I dont know why but I got the screen you see in the photos, and the screen you show. But, I only got enough gaskets for one or the other.

 In my case, if either one of them fit that would be the one that got used.

 Its off a lot. Maybe someone knows where screen like this can be bought?

 I dont know if bending and making "wriggle" room would even get me enough, or if I would just end up making the situation worse by breaking the pipe or loosening the joint. *conf*

The tube was not a tight fit in the case on my bike, it was removed by the machinest when he was milling the step in the cases flat in the sump plate surface area, I simply slid it back into place, using a gauze as a guide, and with some loctite to hold it in place.....

So, if you heat the tube you MIGHT find whatever glue is holding it place will soften, and it will move easily.

Worth a try anyway I reckon  *smile*

Mine wasn't a perfect fit but not as bad as that. I kind of nibbled bits of mesh away until it went through without straining (see what I did there?), and then soft soldered at the bit of gap I now had to minimise that.

Looking at the strainer and the pipe even if the pipe was to fit central in the hole the remaining gap between the pipe and the strainer would be bigger than the holes in the strainer therefore defeating the purpose of the strainer. I would be tempted to enlrge the whole in the strainer until it fitted over the pipe then solder a  home made washer onto the strainer covering up the gap. Or you could  measure the holes per inch in the strainer and buy the same material and make your own strainer to suit you can buy material like that on ebay. I have done it and renewed the mesh on my oil filter and petrol filters.

Although like many I have fallen out with Draganfly that gauze looks pretty cheap compared with the Draganfly equivalent that I bought from them........see

 I have worked at unfolding the edge around this strainer, hoping I can rotate the screen to a better position and then crimp the thing back down but its not working.

 I have no knowledge of the wizardry used to make this flimsy thing, and its become more and more bent out of shape (read: damn near unusable already).

 I have looked at many of these for sale, and they all look clocked to the same angle.

 I am going to have to make something up because I cannot get up the balls to go after mine with a torch and pliers.

Using nothing but buckets full of brute force and ignorance I have succeeded!  *smile*

 This was a PIA, but it did work. I still may have to file a bit to get some wriggle room, but its 200% better than it was.

Hi Lee,
Well done on sorting the problem, Theres more than one way to skin a cat (or filter screen)

I'm puzzled by the description of the draganfly item

"Filter plate, large hole 71-1126"
