The Husqvarna 550XP MKII

I'm just asking trying to help and clarify the issue here. When you tighten chain to cut, do you lift up on the bar tip before tightening the bar nuts? Proper chain tension and a clean bar rail and lifting up the bar tip before tightening bar nuts makes a big difference for me.

I'm a never lifter lol. I haven't seen that it makes a difference for me so I stopped doing it yrs ago.

You probably crumple your TP too…

Seriously though, certain saws don’t tension right if you don’t lift. I could see alignment being an issue, though I’ve never had that problem. My 395 has way too much chain slop if you let the bar hang. Surprisingly, so does my 2511. I haven’t noticed any difference on a 550.

I’ve had this saw for a year, cut lots of wood with it. Never had to lift the bar or do any contortions for it to oil before. Tried lifting it today as I tightened the nuts, no change. The oil runs out the back. This is a new oil pump, a new worm gear, a sharpened chain, and a pretty new Sugihara bar. Something’s wrong.

Wow. Sorry.

Yeah. Sumpon’s wrong. You’re sure the bar is dead flat to the plate and the plate has nothing behind it?

i have large mount 28" bar for my 550xp mk2 and it needs plug for adjuster hole. or it will leak trough the clutch cover cavities.
maybe you sugi has oil path to adjuster or stud hole

Happens with the stock bar too.

Who put the new erl pump in? You sure it’s installed correctly?

I did. No, but there’s no change. What should I look for?

I’m not terribly familiar with the 550 but I’ve had that little feed tube come off the pump and leak oil everywhere but the bar. Sometimes it splits. Maybe some pics would help get it figured out.

My guess is your problem is behind this plate. That’s where the oil feed tube is.

You ain't using burnt motor oil in it are you? LOL

I'd check what the Woodpecker said. The video you sent the other day of the oil coming out the bar plate looked good to me. I thought you had it fixed. That hose from the pump to the bar pad must be split or something.

See anything?

Do you by chance own an air compressor ?

Yeah, I'll blow it out and take better pics, sorry.

 

[Timjus]

you could test it now
put the clutch back and block the oiler hole with rag and run it to see where it leaks

Put the clutch back on and run it. Should be able to see where the oil is coming from.
