One case tool to rule them all!

Husky saws that isnt covered is 133/234/238/42/242/246 serie, 40/44/444 serie.
And probleby the old 50 isnt covered, and the same with the old 61/266.
Husky went from UNC over to the metric system through the 80-90's.
Not sure about those old 1100/2100 either since 3120 use a different factory kit set.

 

[Mattyo]

whats the thread size on the 242?

 

[Tor R]

M8, and 3/8 UNC.
It isnt a serie who is important to cover, one of those series where the factory kit rule

 

[Mattyo]

@Tor R I will respectfully disagree and say that the 242 is important to cover ...for me...because that pto bearing is NLA and would benefit from this set for sure.

I'm not personally familiar with the 242 but if you are wanting to save that bearing...this set will help.

Question...is that 242 pto seal....does it seal against the crank (like the stihls) or the inner race? Like the husky 346xp?

 

[Mattyo]

Also...the flywheel side 242 is m8...which I have covered. The 3/8 I don't obviously. Which means if I can get a tap...I can have Fred make custom rods for those that need them. So....other than 3/8 ...what other clutch side threads did I miss?

Another question. ..what is the diameter of the crankshaft on the pto side of the 242xp?

 

[Tor R]

242 crank diameter is 6201 bearing.

Flywheel side threads are normal M8, M8×1.5 I belive.
Your kit has only M8×1.
PTO side is 3/8 UNC, bearing we use has integrated seal like 346 has (best bearings ever made!!!)

Key with 242 is to set the PTO bearing in correct dept, it doesnt have a socket, and unlike most other saws when we torque the case together we finish with the PTO (this is according Huskies workshop manual)
This is the reason why I've always felt that factory tool kit # 502 50 30 07 rule

I know the old 61/266 used UNC on PTO but I dont know whitch UNC they used.

Kit 01 is for 1100/2100, kit 8 is for 3120, I dont know if it was because of different threads since they had different kit number or if it was because of the seal socket or the bearing dept. Kit 8 cover 181/281/288/298/394/395/3120 so since it didnt cover or could use the kit 01 there gotta be a bigger issue.

I thought to figure it out soon, I've started to buy 2-3 mounting tool kits each time I order something from my dealer, and my kits start to reach them bigger Huskies now

 

[Mattyo]

Very interesting. ..tx...I'll respond more later

 

[Mattyo]

Ok, i think m8 typical thread is 1.25 ....not 1.5. gotta figure this out before I order a tap

also, just to confirm 3/8" UNC is 16tpi LEFT HAND because its a clutch...right?

it may indeed be possible to put both of these threads on a single threaded rod. if so, a custom threaded rod to go with the kit isn't too hard to make.

I don't know how many people are rebuilding 242's .... but it would be nice to have an exact match threaded rod


ok, the 3120 .... I'm pretty sure it just has the 6203 bearings..yes? if so, then the large sleeve will work. I don't know what the thread pitch is though for that one. if its the same as a 394, then my kit should work perfectly.

Thanks for the help Tor... good info here

Constantly refining and making it better.
Good on you Matt! [emoji106]

well, I think the kit as is does hit the high points, but its nice to know that we can tailor this to whatever people need.

right now it may not be worth it for me to chase individual little projects, but I think the 242 is a significant enough piece in the diy world (even though i have never done one) that it bears covering in some fashion.

 

[Tor R]

I had to find my notes, I got a thread table where I note it down lol M8×1.25 and UNC 3/8 16pitch is 242.

Aint many 242's left, and very few of them will be split in the future, and the main reason is that the PTO bearing # 501 49 40 02 has been NLA for a couple year ago, its still possible to buy them from slacker, for the whopping price of 140$ + shipping.

There isnt any problems with the 3120, we use the same kit (#08) on 281/394/395 and 3120.
I dont got any big Huskies to compare things against, nor do I have knowledge to know of the flywheel threads or the pto threads where the same from 1100-2100 to 3120 , but when the 1100 and later 2100 came, Huskies mounting kit was # 502 50 30 01. The kit available for 3120 is # 502 50 30 08.
Lets hope those threads are the same and its just a different socket, but those things can be checked through part list.

Got my kit today
Looks good Matt
Will be awhile before I get to use it but I will give feedback when I do [emoji4]

If anyone has the thread sizes for an 1100 and 2100 ... i'd love to have it that info.

I know I'm asking a lot, but do you have a photo of the PTO side of a 242, without the clutch .... just showing the seal/bearing/crank and same on the flywheel side, no flywheel, just showing the seal/crank area? I'm sure not many will be splitting the 242 case, but its just such an iconic piece that its nice to know that I CAN make the kit to fit it, if someone needed it. ... then the next piece of info I need is whether or not I can fit a 3/8" -16 unc tap in a 5/8" threaded rod... I think so, but the wall thickness is gonna be a tad tight lol.

if anyone has a 242 (or any other with those odd sizes) please contact me for a custom rod.

sometime when I have time I'm going to try to gather all this info together and post it in my vid descriptions. Tor R gets the credit for sure!

You've right about that Matt, 242 is an iconic saw, neither Husky or Stihl has made such a compact saw after the 242, shorter and more slim and toned against 346, 2.4kw on 9.9 k, wot 15.5, hard to beat a saw like that

242 crank axel dimension is 12 mm.
Flywheel side:


Another picture without the seal (I was going back and forth before I decided that I'll do a full rebuild with this one......one day)


PTO side:


overview of one who was about to be put together (mounting kit 502 50 30 07):


This is the issue we have with that famous PTO bearing (6201 vs slacker 543301) (if we used an 6201 bearing we would only have 2 mm left for an seal solution before the oil pump come...).
I've been a lazy duck, thought to build together one with a different bearing solution, but I swiped over Norway for those 543301 bearings, but maybe one day lol


I hope those pictures can help you Matt

With the correct tapped ends on the threadrd rods...my small sleeve will work with that saw no problem. ....tx

12-20-4 is the flywheel seal Matt. Your smallest sleeve is 19 so that should work out well

INTERESTING ISSUE

I don't know for sure if this is the problem yet, but its still interesting!!!

One of the members i sent a kit to had a bad rod. somehow the m10 hole didn't have threads in it. Ok.... ship him new rod.

Now he has ANOTHER issue. the m12 rod stripped out. ... by hand. ...no excessive torque. hmmmmmm china 660

I have a china 440 crank here laying around. same thread m12x1.0 LH. I have a bunch of rods, tried them all ... tight. GOOD.

measure the crank threads diameter ... OD is 11.90 MM ish.

measure the ID of the rod. 11.54 mm. ok, so this means .35mm of holding power. seems to work fine.

BUT, the crank that stripped the rod was only 11.6mm! a fluke crank? I think so, .... so CHECK YOUR CHINA 660 cranks!!!! measure the diameter before you put the threaded rod on it and make sure it grabs secure.

any issues, I need to know!

 

[Mattyo]

Housekeeping...

#1, I was expecting some small rods Saturday, they appear to be late. They are in springfield and I have no idea why they didn't make it down here today. As soon as I get them kits will go out.

#2, dealing with the issue in my last post... I just got the rods that were supposedly stripped out. one of the m10 flywheel rods indeed is a bad rod, there are no threads. BUT, the m12x1.0 660 rod still works perfectly on my m12x1.0 crank threads/bearing/440 crank.
SO


SO SO SO...... CHECK YOUR CRANK THREAD DIAMETER on these china saws. m12x1.0 should have 11.9mm OD on the threads. it its 11.6 its out of spec!
