Hi Karla,

I am not sure if the gear is being engaged properly, I didn't know about the trick that you mentioned for aligning tabs in the gear, I may have overlooked it.  I will open it up again to see.  I've been away from it for a few weeks.  Regarding seeing the oil come from the pump, I saw a little trickle as I was turning the piston.  I could see air bubbles too.  Then when I turned it in the opposite direction I didn't see anything happening, but then reversed to the other direction and I saw another trickle.  I am assuming this means the pump is working.

I will let you know if it turns out the gear wasn't lining up properly with the tabs.

Thank you, and I'm sorry it took so long to get back on here to respond.

Hi Karla,

Good news, I was able to finally get the oil pickup hose out.  What helped me get a hold on it and pull it the rest of the way out was by removing the bolt that holds the chain catcher and vibration damper in place.  I was able to get enough room to get needle nose pliers in to pull it out.  After cleaning I tried to put the replacement screen over the original part but there is nothing that the part can clasp onto, so I didn't put it on.  I will have to buy a new pickup hose fitted with a screen.  When I put everything back together it still didn't work, but I realize, though hard to see, the plastic gear is stripped again.  I will have to buy a few of them so I won't lose time everytime one gets stripped.  I did verify that the pump works just by moving the gear with my hand and seeing oil coming out of the hole.  Anyway, at least I know the pickup hose is allowing oil to pass to the pump.

Thank you for all of your guidance!!!!!

Thank you, the picture is very helpful.  The problem with my 455 is that it's not pumping at all.  I first noticed this last fall.  When I took it apart I found that the pump was frozen and the gear was stripped.   I replaced both but I still wasn't getting any oil.  This time I brought it to an authorized dealer, they ordered another gear and maybe cleaned the hoses, I should have found out exactly what they did.  The oiler worked for one session, then broke again.  So this time I'm trying to blow both hoses out, and was in the middle of trying to remove the suction hose when I found this site and posted my question.  I did one test prior to attempting to take the hose out.  I ran without the bar to see if any oil was coming out of the pump. It was dry.

I hope I can send a final note on Saturday telling of a successful outcome.  I will also be making sure the bar is cleaned up.  Thank you.

Thank you, that is exactly what I needed to know.  I was worried about pulling to hard on the hose and breaking something.  Now I understand and can go ahead and pull it out with more confidence.  Thank you very much, I will let you know how I make out this weekend.

OK, thanks Karla.  I guess I was afraid of using too much force is removing the suction hose.  I will try again this weekend.

Hi Karla,

Thank you for your quick response.  I think I used the wrong terminology for the hose I am referring to.  I'm actually talking about the suction hose that runs from the oil tank to the oil pump, not the hose that goes from the pump to the bar.  The workshop manual describes it on page 30 as the oil suction hose.  That is what I'm trying to figure out how to remove.  Thanks for any info on this.
