willows40 Posted January 21, 2009 Posted January 21, 2009 hi does anyone have any idea why an oil pump will not pump oil round a 1500, its siting in the dizzy as it should and worked ok until change the pick up from a dolly to spitfire pickup.how much can go wrong with onecheers andy
Vinnyfastcar and Carol Lamity Posted January 21, 2009 Posted January 21, 2009 I had the same problem, basically in my case changed the pick up too, BUT the one I put on had the pass through holes in a different place! (they aren't all the same!) hence no suction what so ever - whip it out and it'll more than likely be a eureka moment......
thescrapman Posted January 21, 2009 Posted January 21, 2009 AndyIt may just be too dry to start sucking.Take the dizzy out, pour oil down the hole, and put an electric drill on the shaft and give it everything in reverse.Worked for me twice now.CheersColin
GreenV8Machine Posted January 21, 2009 Posted January 21, 2009 Failing that, pack the gears with vaseline too.
willows40 Posted January 21, 2009 Author Posted January 21, 2009 ok will give it another go tomorrow, colin if i take the dizzy out do i have to take the drive out as well and if so how do i do that?this spitfire is driving me crazy really don`t want to take the engine out again,matches and petrol is next thing :)
thealligator Posted January 21, 2009 Posted January 21, 2009 My MK3 motor would nt pump oil up after been pulled apart to check the pumpthen I removed and refitted the relief valve, it was fine afterward.No idea why.
Alex Posted January 21, 2009 Posted January 21, 2009 If you have to take the drive out you can use long pliers or similar,just pull and turn at the same time.Alex
thescrapman Posted January 21, 2009 Posted January 21, 2009 AndyTake the dizzy off, Line up the drive gear slot to somewhere you can replicate (vertical or horizontal) and then remove the drive with long pliers. Twist and pull out in one easy movement.DO NOT MOVE THE CRANK!I have used a de-cogged PI dizzy drive as it is a lot longer!If not make a tool to fit the slot that also goes into the drill.Anti-clockwise as fast as possible. Drill will slow down a lot when the pump starts pumping. My Pi took about 5 mins before it loaded up.You could also squirt oil into the releif valve hole. Anything to get some oil into the pump to help it prime.CheersColin
willows40 Posted January 21, 2009 Author Posted January 21, 2009 tried the relief valve made no difference.
willows40 Posted January 21, 2009 Author Posted January 21, 2009 also tried pumping oil in hole, i take it 1300 oil pumps are different as have one of them

thescrapman Posted January 21, 2009 Posted January 21, 2009 They were different, but only 1 type commonally supplied now.CheersColin
Vinnyfastcar and Carol Lamity Posted January 22, 2009 Posted January 22, 2009 Mmmmm I did all of the above too...... it could be one of them.....but I still think it's a pickup/body mismatch - obviously i'm not pshycic, but I bet it's a mismatch (wink)
willows40 Posted January 23, 2009 Author Posted January 23, 2009 ran a drill for a good 10 min still no oil so gave up and put the old pump from a 1300 herald in and it worked straight away so i thing vinny was right just got to change the big ends now :'(
