Use an old small paint brush to clean around your caps (pole saw, chainsaw, ect) before you take them off. If you want to do this job more comprehensively remove the top half of the gear case with gearhead chucked in vice by the limb hook. Tap the pump out the housing with a small flat punch. Install cleaned pump from the bottom and watch alignment of pump discharge port side. Clean, re-grease and re-seal gear box housing. Pretty easy job.
I use simple green at a 1-1 ratio and spray the head and redivide with it and rinse it off, takes less then a minute and won’t damage the rubber gasket and will clean it right up! I was surprised when someone told me about it! Better then brake clean and cleaner
If they made the oilers do what they’re supposed to do...they wouldn’t sell as many chains. Why would they want to possibly supply the best designed fully adjustable oiling system with sufficient flow in any condition? Husqvarna Rancher is notorious for oiling system issues.
Great video and you are spot on with everything except (everything is filthy) you don't say how to check the action of the pump itself! As the gear (and plunger) is rotated on the end of the pump unit, it must go in and out slightly at the same time (8:36). This is what makes it pump the oil (sucks on one side, rotates 180 degrees and squirts out on opposite side orifice). I took my Stihl chainsaw apart today because it won't pump oil and found the plunger just spins, instead of oscillate in and out as well. This indicates the side pin that engages the cam groove on the plunger, has sheered off. So, I'll be ordering another on ebay in a minute. The part is too cheap to bother repairing.
Jeremy another great video.I am working on a HT 101 polesaw at this time,rebuilt the carb. Pressure tested and vacuum tested it no leaks,will throttle up won't idle change the fuel lines and filter,spark plug.Can you pressure and vacuum test a 4 mix for a air leak, Thank you.
How about 5 mm x 1.25. A regular Stihl muffler bolt. It is the same removal method you use for a Stihl ms 1180, 250, etc. this is why I hit the oil and gas caps on my saws with compressed air or a paint brush before I remove them. Can’t keep everything out but I can get rid of most of it. You have to make sure the output hole on the pump is properly aligned with the hole leading to the discharge port. It is the small hole in the side of the pump. The imput side is the slot in the end of the pump. I clean out the oil and gas tanks with break cleaner on my saws at least once a year with break cleaner and compressed air.
Thanks for sharing. Liked your oil pump puller!!!!!!!
Oh, l like your haircut. I like to keep mine on the short side too.
Great video mate, the guy I work for has that same issue with his pole pruner, I'm sending him a like to your video immediately 👍
Awesome lesson teach! Very well explained
A thoroughly enjoyable watch. The best of attention and care from the medic and no health insurance required!
Very informative. Thanks.
That’s good to know! Thanks!
Great video Thank you!

Great video as usual Jeremy. Got a similar little puller set up for pulling those pumps. I usually find they’re clogged with saw dust.
Great video. That's helped me out and saved me £210!
Thank you mowermedic1
Nice jobe buddy you are a good mechanic
Going to attempt this. Thanks for the part about spinning the cutter head with the tool. That will help. You are the man.
I have found a few, all on Stihl saws, exact issue as posted. Check em or get em checked!
Thanks for the practical tutorial very help full ,point taken clean your gear first ,thank you ,jimmy Australia
Great video!!
Nice video Jeremy! Ive never seen one of them apart! I have now.🎬🇺🇸Roger
The STIHL pump gear goes in and out as it spins. Maybe that’s how it pumps. Very clever. Good video

All.you have to do is clean the dirt in the oil pump and put it back on
That’s correct

Good Job Doesn't look to difficult to do. Is the pole saw attachment in the kombi the same?
Muy buen video amigo lo felizito grasias
👏👏👏👏👏👏👏👏
Just wondering, how do you change the spur gear?
No if you look on the inside of the case there is a diagram
Guess I missed what size bolt was used to pull pump ???
a guy i know has got a barely used hvsquarna chainsaw thats not pumping oil could it be the same issue?
You pull the pump out and clean the dirt out and put it back on it will oil trust me I do a lot of them
What size screw?
Great video. My oil valve/breather is leaking. Any advice on getting it out or cleaning it out? I'd rather replace it. Thanks.
clean it from the ourside, push a small opject in it, to move the ball and hopefully reseat without debris between the ball and the funel
thank you@@majstealth
you dont have compressed air in your shop, do you?
