Husky 2100 oiler problems

[Oregon_Rob]

Was not getting much in the way of oil output. I tried flushing the tank, to no avail, so I pulled the bar off and watched the output hole with the saw running fast enough to engage the clutch. I just got a little oil and some air bubbles. I pulled the oiler out, confirmed that the little screw was in the correct hole for maximum oiling and cleaned every thing out and re assembled. Now I don’t get any oil. I looked a little, but not real hard and I didn’t see how the oil is supposed to get to the pump. There were no hoses going to the pump and I didn’t see any holes in the case that seemed to have oil to them that matched up to holes in the pump. I am sure I over looked something.
*Can someone point me in the right direction so that I know where to look next time I pull it apart?
*I am wondering if I should pull the pump apart and look at the seals and o-rings…?
*I noticed some small hoses behind the muffler, are these part of the oil system?
Oh yeah, *What is the good compression range on this saw? I had it checked and it showed 145 PSI. Mike told me that below 125 it was no good, but I don’t know what the upper end of the range is.

Here is the 2100 oil pump. Look at the black rubber gasket with two holes in it. One is intake. One is out go. The gasket must be there and in good condition. The intake mates to one of the hoses behind the muffler. Check the hose for leaks and splits. Pop it out of the tank and look at the screen on the end. It may be plugged with sawdust. Checks the clamps for snugness. Be sure the gears aren't stripped and that the clutch lugs are engaged into the drive gear lugs.
If none of the above helps, let me know. (I know the seal is bad on the one pictured) Mike

Mike,
If you are talking about the seal between the pump and the case side, then it is indeed shot, in fact it kind of looked rotten. Also, since I didn’t know there were holes to line up, it is off somewhere other than where it should be. Is that a commonly available part, or is it something you can hook me up with?

Regards,

Rob

Even though I sent an e-mail, I will post a followup. Get a new seal for that and a new seal for the crankshaft and don't forget that there is an o ring that goes around the outside of the boss for the crankshaft seal. Get all three new and put her back together. Check those hoses too because if the one rubber went bad it may indicate something was attacking/desolving the rubber and you need to check them all.

OK, I went home and removed the oiler again, saw the two holes and seal. That seal seems to be fine. The one that was torn up was the one that goes over the oiler to protect he crank bearings.
Of the two hoses, the lower one, which I think must be the supply is fine. the other hose is OK, but the nipple for the return hose has a very small hole that must be for meetering or limmiting the flow back to the tank is plugged. I will open it up when I can find a small piece of wire.
I took the pump apart and found the shaft looks good, but there are no washers and no spring inside. I have the Claymer pro series service manual that shows the spring and washers.
I still haven't figuared just how the thing pumps oil, but I am suspecting that without the washer and springs I don't have much of a chance.
Any thoughs?

Do not try to unplug that fitting. It has a check ball in it to keep the oil flowing in the correct direction. If the pump is missing the washers and spring inside then it will not work. The pump works by moving a rod back and forth in an enclosed tube. The gears spin the rod and the eccentric, on one end of the rod, rides on the adjustment screw. As it spins the rod moves back and forth.

Can you help with PN's and or dimensions? If I can't find the parts, I should be able to make them.

 

[rupedoggy]

I have tried to attach an ipl for those parts. If it does not come up, a trip to the local Husky shop should let you see what you need. Mike

Mike,
Came through loud and clear and very helpful by the way!

I can't say it enough, thanks for the help!

Progress

Well, just by cleaning things up, blowing out passages… the oiler is back in operation. Actually made a few milling cuts last night and things seemed to stay oiled.
A couple of times near the end of the cuts, the clutch slipped. I think the chain was getting pinched. It is a little concerning to me that the clutch could slip, I was only cutting alder at about 16” wide. Anything I should do to service the clutch, shoes or Drum?
