Oil pump upgrade 15mm wide

im fitting the KTM ATV 15mm wide oil pump, stock is 10mm wide

parts are in greek style tub providing inspiration for extra lube



apologies for the crappy phone pics

bored out the oem oil pump cavity 2mm deeper and recut the oil passages under the rotors. will put up a cad drawing of how to do that later



clocked all the round bits while it was in there and drew a new lid with a 3mm recess



couple of shiny bits



can see whats going on here i hope





there is an easier way to achieve this with a spacer plate separate to the lid i made one of those as well. advantage is that the recess for the rotor and the hole for the shaft don't have to be spot on, i have 3 sets of cases here and they are all different enough to make the one piece lid a no go for mass production .....

if you wanted to fit the rfs 12mm wide pump instead all you need is a 2mm thick spacer cut by water jet, ill put a drawing up later in case someone wants to do it.

more details on the shaft and pins etc later.



this is the part im using


(2009 ktm 525 exc ATV) 77038011000
Description: OILPUMP ROTOR 15MM G-164
Retail: $35.89
Your Price: $28.71

the 12mm wide one from the 525 rfs is G-95R

(2007 KTM 525 exc) 59038011012
Description: OILPUMP ROTOR 12MM G-95R/003

cooo-oool!

1) How the hell do you know what to do?

2) i assume you need access to a cnc mill for this?

well there are only so many ways something can work, I choose one then start making it then change my mind 3-4 times and fiddle around till it really works

cnc mill removes nearly all excuses for making anything but this is not a difficult part to make with manual stuff

if you made a 2 piece adapter with a spacer plate and a separate lid it doesn't even have to be very accurate, could do it in a lathe or a mill quite quickly.

for the 12mm rotor just need a 2mm thick spacer and use the stock lid

for the 15mm rotor you could make a 5mm spacer and a new 2mm thick steel lid.

if anyone wants somewhere to start these might help

spacer dimensions for the newer cases, the older ones pictured above have more room

2mm thick for the 12mm rotor, 5mm for the 15mm rotor

OEM pump bore is 28.975mm at a clearance of 0.12mm between it and the rotor



lid dimensions FWIW I would use brass or steel, OEM rotor to lid clearance is 0.05 to 0.08mm and needs to be checked

for the 12mm rotor just use the oem lid, make it thinner and use CSK bolts if required

Thanks from mars, The_Force and spanner

Nice stuff Bushie

I know what you mean the cover can be difficult to aline.

If I was to do it again I think I would increase the bore in the case
to accommodate a sleeve 15mm long and make a cover to fit over
it.

I spent a bit of time porting the oil inlets and outlets as well.

Cheers spanner.

Ta Spanner

I remembered your great idea about the sleeve but im all sleeved out after the mains time for some billets, preferably Swedish

I got the measurements from my 02 for the location of the shaft and the rotor, they align nice in the 02 but not the 06 or 08 and the 08 is different to the 06 LOL.

there is a message from husaberg there i reckon about tolerances in how they just slap a lid over the top.

Are you thinking about selling these spacers?

no sorry hacker my real job keeps me way too busy and pays far too much to make trading in trinkets worthwhile.

I plan on making some more complicated things for bergs in "injection" molded Carbon fiber at some time.

if anyone wants to make a heap of pump spacers or lids go for it .

I've seen many of your projects.
What do you think of inserting the oil jet to the engine case?
I have 2004 engine without the oil jet that cools the piston.
I want to drill oil passage and put jet from husaberg >2005.
What do you think or what I must remember?
Is this possible?

I think its a great idea

assuming the main oil passage is there to begin with it would only be a matter of getting the angle "right". but any squirt is better than none right?

I would first make a flat area for the drill to start on.

the oil passage you are aiming for is quite big 4-5mm diam so hitting it with a 2-3mm drill for the jet thread is easy. if it goes wrong just plug it up and drill another one.
