06 oil pump- easy enough to change?

[doobin]

Hi all

 

Need to get the oil pump out of my 036- it appears to be supplying OK when revved up high with no bar on, but is not oiling anything like enough in normal use. Almost certainly the result of being left for two months with veg oil in

 

I have a pair of donor 034s. How do I go about stripping the oil pump out?

 

I've searched the forum, but apparently the words '036' and 'oil' are too short. So '036 oil pump' just searches for 'pump'

 

Thanks

Fairly easy to do, link here to the parts diagrams for your saw http://www.keepandshare.com/doc/2062200/036-pl-pdf-july-12-2010-4-29-pm-526k?da=y

 

remove the side cover, then remove the cir clip and washer holding the clutch drum in palce, slide the drum and bearing off. Next to remove the clutch REMEMBER ITS LEFT HAND THREADED. You will need to use a suitable stop through the spark plug hole to stop the crank rotating, you can get special tools but a piece of 3/8 rope works just aswell, by hand using the clutch turn the crank in a clockwise direction so thi piston is just before top dead centre and feed your piston stop or rope in through the spark plug hole. DO NOT ROTATE THE CRANK A FULL REVOLUTION WHILE THERE IS ROPE IN THERE OR IT COULD FALL INTO A PORT AND REALLY CAUSE A PROBLEM. With the crank locked up remove the clutch. There is next the worm gear and a couple of washers that slide off, the oil pump is held in place with two T27 bolts, undo these and the pump is loose, feed the oil to bar pipe back through the hole and the pump will just lift off.

If it's been left for 2 months with veg oil in, good chance it's just blocked up? Sure someone else had a similar problem back along?

That's what I'm hoping, but have two backups just in case

Excellent third post, thanks for your help. Could do with more on here like you

 

I ran the pump backwards manually with my thumb to draw freshly boiled water through it- problem solved!
