Huztl FarmerTec MS380, MS381, 038 Build Kit Start to Finish

[Bedford T]

Pressure test was this morning, failed miserably but it wasn't the seal. Now it's the oil pump leaking like crazy. I pulled it out and didn't notice any O rings except the big one on the front. I think I'll have to take the pump shaft apart and replace the O ring inside the pump body..probably just put a little Dirko around the end of the pump upon install, that big O ring on the end is kinda expensive so trying not to replace it unless I have to..I think I already have more in this saw than it's worth..

One thing about those tests they sure shorten the guessing game.

Right now I'm guessing how many places these saws can leak! A lot of people around here like the 041s but I think I'll stick to my 039, seems a lot simpler..

The 272 is a great platform. One of the iconic Husqvarna saws. It would be the easiest to build of the kits they currently offer. They are a joy to wrench on. Hopefully they price it cheap.

Yeah. They probably need to consider what will have the most demand for the kits but also need to consider the number of used saws in the market that need parts.

One thing is for certain it's all coming to us. They have opened the spigot.

 

[tbohn]

It arrived. They are now bubble wrapping several parts like case, cylinder, flywheel, clutch/drum and a couple more.

The case looks to be equal quality of the other huztl cases I have worked on.

The cylinder bore looks good but the plug threads are very rough and not machined. It also has a partial divider protruding into the intake port. I don't know if this is on the oem cylinders.

 

[Bedford T]

That looks like a defect. But it also looks smoother generally. They said they would fix the packing. Gotta hand it to them. They are their word.

 

[Bedford T]

Wonder if working an old plug in and out would smooth it up. Or are the threads missing?

 

[Bedford T]

And the locator pins are in place too

 

[davhul]

Some old saws had that in the intake. I can't recall all which ones

 

[Bedford T]

Good to know.

 

[Bedford T]

Hurry up postman?

Photos of plug and decomp threads along with other cylinder photos.

Mine did come with a spur sprocket. The plastic is typical of all the huztl kits. The crank is shrink wrapped and bubble wrapped. It has an excellent finish on all surfaces. By far better than previous huztl cranks. The fasteners appear to be grouped for the area they are used.

Do you think you will need a thread chaser? I can't tell from here.

I can't thread a plug in by hand even one turn.

The 038 series had the protrusion on the cylinder end of the intake port. So did the 034 but not the 036. I believe to support the rings.

In the pictured cylinder the intake protrusion should be centered in the port. At least the OEM ones are.

Also the chamfering of that port is fugly. The end of the ring support had way too much of the lining ground away at the tip, it should just be a chamfer, and the top right it looks almost like a gouge by the grinder rather than a chamfer. You can always blend in a proper chamfer, but you can't put the lining back on once it's gone......

How does the shapes and insides of the other ports look? Is the lining good up to the top of the bore?

The chamfering is there but it rough. I will be touching them up. I will definitely be checking if the rings drop below this piece. The exhaust and transfer ports have some slag in them that I will try to clean up.

 

[davhul]

That's correct about ring support. I believe the 084/088 also has it

 

[Ozhoo]

As mentioned, the tonsil is there to add support to the rings. The rings only ride down it for a couple mm. That said, that's one ugly tonsil.

 

[tbohn]

It look like the only thing to install prior to putting the two case halves together is the oil pick-up assembly. You can't do that after its together. Obviously the crank goes in too.

The bearings are nice too.

The oil filter/hose can go in or be replaced at any time. You can do it your way, but as we say in ol' Mexico, NO NECESITO
