Thanks for the ideas I would like to seee how the new G372 would go with the pop up piston and intake and exhaust mods planning to do one very soon would be nice to see if there are any hurdles.
I have the 52mm pop up non xtorque piston from lil red barn in my 372 with the 52mm mako cylinder and it is a great combo. I’m only running the top ring on my piston and have done a dual 3/4” port muffler mod and it runs absolutely amazing and snappy. Only thing I’ve wondered is the secondary transfer port is about 1/2 the size of the primary, not sure how much difference that makes.
When I put the original kit cylinder back on my ms 460, I used 1184 on the base gaskets, instead of Dirko, that I was not pleased with its sealing. I have had no sealing problems with the 1184, as yet. I still have the newer cylinder I got for the 460, but it’s squish was so short I could not crank it, reliably. With the slightly larger squish of the original kit cylinder and two base gaskets it cranks and runs reliably. The 460 has lots of OEM parts on it, but is still for the most part Farmertec. The best upgrades were a Stihl carb and clutch springs.
Can the case be saved by boring it out and dropping in a sleeve? Could also adjust the tolerances a hair to maybe try and prevent it from happening again, if you think this was fixed by adjusting the bearing fit on the later saws. Thanks for the video.
Sure, but at what cost? Something I may try in the new shop at some point. But for most, to hire someone to attempt that would cost more than a new set of OEM cases. IF there was a shop set up to sleeve and put in bearing ...they could be pretty busy if the price was right. Split the difference between AM and OEM cases maybe.
@@afleetcommand Yes, of course. I just wanted to ask as you said they are junk. It looks like a set of cases is ~$360 retail? It would require a custom fixture on a lathe and tube stock on hand though. I have a friend who does this a lot for go kart engines.
As always great info backed up by fact not guess work ! That XT had certainly done a lot of work by the look of the lack of paint on the front of the oil tank, had it been set at a couple of hundred rpm shy of the max you recommend or at the max ?
seen that case damage before. had a customer that every time he wanted to trade in his saw and get a new one I knew his trade in saw was no good, he would always have bad pto side case. his filing of the saw chain drags would cause to much chatter and pressure on bearing ruining case.
Those saws are awesome, and if you have a good dealer, who gives you feedback freely with CST, you really can understand not just about your saws life, but also some of your work statistics. Really good data and can be used in many ways. I wish more dealers would promote that capability....really a win-win for both the dealers and the customer..really is. It is a dealer only device but having a relationship with a good dealer is a good thing for all involved. The CST is a draw that I wish was promoted more.
@@afleetcommand the CST is listed in the spare parts list. I think it is available for purchase? should be somewhere below $200, thinking of buying it sometime in the future.I like working on my saws myself.
@@mart446 But you can't access the Huqvarna service site without a password and they only are given to service departments for dealers like the one I work for, so please don't spend your money on the "hookup hard ware" as you will most certainly be disappointed. Think of it along with your computer as a "terminal" to a central system, Husqvarna's service site; and with out that connection you really can't even run the software's interface. AND instead please strike up a relationship with a Husqvarna dealer who understands these things both from a technical and support perspective.. BOTH of you will be happy as a result, THAT is the take away I hope folks will get over time.
Walter, when you used the Lil red barn pop up pistons have you checked the squish before (oem or aftermarket piston) and after with the LRB piston, I'm curious if they are a little bit taller or basically the same as a OEM. Another question is on the newer covers where they have captured nuts, do any of the current model saws have the cover with captured nuts that will fit the 372xp? Thanks.
Did that on my 365 48mm build. Can't remember exactly how it measured but I did measure if w/o base gasket there in that video. Looks to me as if the piston dimensions are as a stock with the additional material added for the popup.
365 OE? or XT. Actually never used the Huztl carb on anything other than a Huztl saw. Suspect it will fit directly on an XT intake. Have to modify the boot on the OE's so you can rotate them. Did that in one of the video's. Only used OEM carbs on my builds though. Some I have to swap the throttle plates to a later version to get them to idle.
One just has to wander if running the chain too tight may have something to do with at least a few of the bearing pocket issues or maybe even the heat generated by the inboard clutch assembly causing the case material to expand at too low of a temperature due to an improper material mix thus letting the bearing spin, just a thought. It appears that Husqvarna may have had a material issue and may have fixed it with an updated blend of materials being you haven't seen this issue for a few years now. Again just a thought.
But the bearings are never "spun" , those things are just pounded open. I'm sticking to my heavier and less dynamically balanced X-Torq...which they tinkered finally came up with a mix of things that made them statistically acceptable. Why they wanted to be below 13,000 in the early years. There may have been other manufacturing issues. But that new design top end had to be a factor. The good news is they did sort it out.
Thank you sir for excellent explanations and great videos. I am inspired to try to build a kit from Holtzfforma. In one video you and Bob discussed the 372 was going away? What is the replacement? Thank you sir.
afleetcommand You would know best. I haven’t seen a product called QuickMetal by Loctite for decades. I worked some miracles with it in the field. Nothing turning 12K RPMs though.
I test them and they either work or not. As I have said for a decade OEM always is the most reliable and if there is any question....that's where to go for the best reliability. I try AM and run them so these things can be documented. And for some they make sense.....but if there is a question....OEM every time. What I put my name on is being a person who will test and document the experience so others can decide for themselves. Nothing more..:)
That is correct, that was dealer work, the only way to get that is being a dealer. I do work for one. And the only way even the locals can get to me is through dealers any more. So nothing has changed.
My 372xp went south for the winter (case bearings maybe lower case needs to replaced) if you fix would like to ship to your location for repair?? Let me know .
Thank you for the consideration, I don't do anything over the internet or through the mail. Have a set of customers I support and really can't take on any more. Your local dealer is probably the best bet...or buy some tools and do this yourself..:)
Do you cold press the bearings into the case Walt? If so, perhaps a worthwhile experiment would be to use heat so the bearings just fall in place. Just a thought, hope all is well down your way bud.
Your kidding right? Been using heat for decades on cases. Like in the video prior, I use a Turkey Roaster at 300 degree's and the bearings just drop in. On those older builds I used either a hot plate, wood stove, or Heat gun to get the cases in the 280-310 degree range before removing or replacing bearings. I think my very first video in 2013-14 was having fun using a wood stove.
SO every saw I have ever stuck together from the bottom up including the one in this video was with the heat differential method...:) And every case since the 1970's on the dirt bikes and out boards as well. The Turkey roaster is the latest ( this last year ) tool and is the best as I can have multiple cases in there to speed things up vs a heat gun.

Because the 372 Original Editions are Stone Axe Reliable, wasn't until the "epa" inspired X-Torqs arrived all this crap shows up. I build back to OE, but you know that.I would build you an OE more along the lines of a 371 with the 51.4mm top end. Like the Jonsered I build we call the 2175..... and to be accurate like I mention in the video, Husqvarna sorted out even the X-Torq's over time. Post 2017 they are as reliable as anything on the market. Just took a couple of changes....and the good news there is everything is retro capable to any of the X-torqs. AND last a LOT for folks who modify saws prefer the X-Torqs..
Time will tell....I usually don't use AM cylinders, in this case the pistons, while ugly; probably will do fine. BUT always good video if it hand grenade's right? So it either runs or frags, which ever. Either path will be on video for all to see. Tangible vs. hear say. Actually I had used the VEC manufactured pistons in "Golf" branded boxes before and they did last quite well. Put them in old Jonsered 820's...ten years ago, saw still is fine. Cylinders? Reference line one.
Thanks for the ideas I would like to seee how the new G372 would go with the pop up piston and intake and exhaust mods planning to do one very soon would be nice to see if there are any hurdles.
Thank you for your very nice movies about repairs, a great pleasure.
You can use the OE cases.i just did a 365 with Italian OE cases.all I had to do was barley grind a little off that notch on the cases.fit great.
I have the 52mm pop up non xtorque piston from lil red barn in my 372 with the 52mm mako cylinder and it is a great combo. I’m only running the top ring on my piston and have done a dual 3/4” port muffler mod and it runs absolutely amazing and snappy.

That would be an interesting test. To put all those good parts in the China XT and run it and see how the crank holds up.
9:05 Can you tell me part number of Husqvarna 372 coil that you are holding in your hand?
Thanks
Just go order the latest and most current coil. Any one after the 2017 versions are good.
I'd like to know if they are making a decent replacement for the rwj-4, it would be neat if you could test if the coil swap improves the g372xt.
Walt, what is the pt# for those Nachi bearings?
Can the case be saved by boring it out and dropping in a sleeve? Could also adjust the tolerances a hair to maybe try and prevent it from happening again, if you think this was fixed by adjusting the bearing fit on the later saws. Thanks for the video.

Thanks for showing this. I'm pretty new to commercial saws and didn't know they were computerized. What's next? Fuel injection?
Stihl is releasing a saw with FI, But really..who cares as long as they cut wood..:)
As always great info backed up by fact not guess work ! That XT had certainly done a lot of work by the look of the lack of paint on the front of the oil tank, had it been set at a couple of hundred rpm shy of the max you recommend or at the max ?
Regarding 372XP Crankcase that had BAD bearing pocket, was it OEM crankcase?
yes
Good video, Walter!

I have husqvarna 365. If buy new type carburetor 372XT from Huztl, can I swap existing carb in 365

Thanks Walt.

Good morning Walter. I had a stud break off on my G660. I was wondering what size Heli coil you used to do your stud repair on your Huztl build.
m8 x 1.25mm, or if you can just check what your bar nut size is..that's the typical

Friend, does the compression change after a few fuel tanks after repairing the piston? Is it decreasing or increasing and by how much?
Try putting dimples in the worn bore with your center punch and set the bearing with green Loctite.
Nope...to much going on for that to work. :)
afleetcommand You would know best. I haven’t seen a product called QuickMetal by Loctite for decades. I worked some miracles with it in the field. Nothing turning 12K RPMs though.
Where do you get those long hex bits you are using in that little impact?

How is the xtorq saw with the xpw cylinder and xtorq carb holding up? Does it have good power?
Better than the original! Very well, have a few out and they all are holding up well. May not be "Flashy" but that is a solid build concept.
@@afleetcommand That's good to hear. I'm going to build one for logging . Thanks for making the video they've been helpful.
Perhaps the nylon bearings are easier on the case ?
That pile of cases in my scrap pile say "no"
how can you put your reputation on aftermarket parts ??
I test them and they either work or not. As I have said for a decade OEM always is the most reliable and if there is any question....that's where to go for the best reliability.

Question: husqvarna 365 x torq they have the same problems as husqvarna 372 x torq, Walter?
Yup. And remember that is PAST TENSE...as the ones I've seen made later than the 2016-17 era don't seem to have those type of issues.
I thought only the dealers can get the firm ware for the new saws. You know. Wow
That is correct, that was dealer work, the only way to get that is being a dealer. I do work for one. And the only way even the locals can get to me is through dealers any more. So nothing has changed.
