Great teardown Doug! Saw looks pretty darn good. Besides the few details you mentioned, overall, it seems like a good saw. Runs extremely well right out of the box. First clone I have gotten that I haven't had to adjust the carb on.
Man that's a bummer on the oiler. A saw that's essentially for milling shouldn't have that issue, it should be solid. With that I would say somebody should consider the price of an OEM replacement in the balance of whether the saw is worth it versus the OEM saw. looks like that oiler, if you can find it, runs almost $300. This video is gold really appreciate it!
INDIANA DOUG, great job on the teardown and troubleshooting, I did not see a hole in the crankshaft at the clutch drum bearing. I like the timing numbers, teardown do get lengthy, fine job sir...
I keep hearing the 1st year or 2 had both jets, no choke, primer, etc. But I’ve yet to see one. Let me know if you can find an image or link Shaun! (Pm me if you want)
@@srcarr52 No Husky service bulletin or IPL reflects the 3120 ever having a H screw, or the change in the filter base casting that would have been needed to clear it, and I have had paper copies of the 88 and 89 IPL's in hand. The WG-7's that I have seen are like the WG-10's I have on the bench right now, pilot hole for the H screw is drilled, but not finished.
@@82f100swb There has been 3 different part numbers for the air filter base, 501899001 through 3, all superseded by the 3 version. Yes, any WG-7 you get now has the pilot hole. I actually prefer modifying ones without the pilot hole so I can move the H circuit towards the center of the carb.
The oil seal will roll and the spring will come off if you just put it on i use a piece of soda can to go around the crank and roll it up so it goes through the seal and push it down tighten the screws down a little then pull the can out.
Saw improvement on the NH872 clone. Mine had interference between the air dam and the intake boot. A year later a friend’s that issue was fixed. Looking forward to more reviews on this saw. Have you ever done testing on the MS 888? Clones have allowed me to experiment,experience larger saws than I otherwise would have been able to. I don’t have to worry about messing up a $1500 to $2000 saw.
Couple responses. -I’ve had several Holtzfforma saws, but not the 880 clone. -I highly encourage you guys to try some timing advance on the 372 clones, the cranks were slightly retarded from the factory.
This saw has alot of design flaws of the oem. Seems to me the oiler vent could be in a better location becuase it will plug solid quicker then one realizes. Nit impressed with the oil keeping the crank seal in place,there is ton of friction and grip. The crank not drilled to allow greasing a clutch bearing is going to be a head ache for servicing the bearing. Lack of dual port muffler with fire screens is a major negative to me. I appreciate your honesty and not hiding flaws.
Thanks for saying this. Of the aforementioned, not having the oem style crank with the oiling capability (which I didn’t mention in video) is my biggest concern. I see a lot of clutch bearings being replaced. There are good qualities on this clone though, but are they where it counts the most?
The OEM 3120 clutch drum bearing was oiled from the crankcase lube. Not grease. The crank was drilled and it had a one-way valve. This may or may not be known or understood... Just information...
@@IndianaDougNo. My 3120 chainsaw from 2011 use the same crank as the 3120K. I found out that when I rinse the crankcase with gas and gas would drip to the clutch bearing hole from the crank. Dunno the earlier saw though.
Thanks for tearin into this. Currently looking into big clones for milling. If neotec is making the big husky saws, is holzfforma going to have these in a kit? Or will these be offerd in a parts kit from neotec? I just have a hard time throwing down that much cash for a clone unless i can put it together myself. I understand the fit and finish of some of the more popular clones has been consistently improving.
I really like the addition of a manual oiler especially on a milling saw, I'm a little skeptical on the durability of the system having watched the video, then again I have never seen or ran a 3120 so no absolutely nothing about them,but at the price point for this, one has to wonder if oem husky parta from a 3120 will be compatible with the clone, mainly parts that prove less than durable, the engine looks pretty dang nice as for the muffler I'm totally with you on the mods.😊
That's really cool,I took notice when you said they have stepped up their game ,I don't own or have very much experience with clone saws, I have run my cousins holzforma g660 and it is a beast, runs awesome even in our cold alaskan temps.
The 3120 does not have a manual oiler, it just has a remote override of the automatic oiler adjustment. Locking the lever in the open position maxes out the oiler adjustment.

Thanks man. Hoping they hold up well milling😁
I wonder what the consistencys like, do you think you'll pull your cylinder at some stage?
@@Chainmale I might just to see. I want to film a little more cutting with it the pull the cylinder.

The oiler has worked fine from the beginning, it’s the quality control that’s the issue
Good job. If I remember correctly, I have heard NeoTec does a good job listening and getting stuff right. Good work sir!
Thanks man, it’s been an uphill battle on this one, I’ll explain in next video.
Love watching the teardown on the neotech nh-8120
Cylinder looks like a really clean casting for being a clone part. Hope they stay that way through production.
Yes, me too. I was really surprised tbh.
Pretty interesting start to a big saw Dave. Will be interesting where these things go.
INDIANA DOUG, great job on the teardown and troubleshooting, I did not see a hole in the crankshaft at the clutch drum bearing. I like the timing numbers, teardown do get lengthy, fine job sir...
Thanks buddy. I did forget to mention a few things that’s for sure.
@@IndianaDoug you did great!
Agreed!
The early versions of the OEM 3120 came with an unlimited coil and adjustable high side carb.
I keep hearing the 1st year or 2 had both jets, no choke, primer, etc. But I’ve yet to see one. Let me know if you can find an image or link Shaun! (Pm me if you want)
Ive got an 1989 3120 no primer, has choke but no high side
@@IndianaDoug You can see a high side needle on the WG-7-1 IPL, of course it's NLA.

I have a good way of doing it with grease. Hasn’t failed me yet. Beer can tin is a good trick for those though for sure👍🏻
Very nice work! Thank you Doug!
👍👍thanks. Timing numbers are very similar to the clone 288’s.
This was an interesting video CF!
First time I’ve heard someone in the TH-cam chainsaw community talk up about racism, big respect ✊✊🤙🤙🤙 also loving this nh8120 content ❤
Thank you👍🏻
Great vid, thx!
Nice review broz, thanks!
Interesting, will spare parts for this saw be available for sale, for example a carburetor? I need this for my 3120😀
They should be yes. I just don’t know when.

My resource says this was only on the 3120K models.

I wonder if it’s original to the saw when new? I’m finding MANY variations to this model over the years, it’s crazy😆
Great video man don't worry about the haters there just jealous lol. I was talking to Kirk the other night about this bad boy lol.
You need one😁
@IndianaDoug Yes I do it will be the perfect fire wood saw 😁😅
You're video title made me think of a song I think you'd like, its "a minor point" by catch 22
This is gonna be awesome!!!!😊
Doesn't look too shabby for a clone👍🏻 and a prototype at that!
Good start!

I believe both company’s will be offering this model.

Honestly, the issues I’ve experienced should be worked out when they are released. This is why I received that saw.

Thanks for the info, I have a feeling this is gonna be one heckuva good milling saw,once they get the minor quirks worked out on the production units.
gdjw has to buy. I can't find how to order for Europe
Will be ready in April
Are these available yet? I can’t find one? Or I’m dumb?😂
No. They told me April, but still nothing.
