damaged piston/cylinder? husqvarna 254xp

[Mattyo]

Make sure those are in the right place...I grease and shove. Odds are they aren't going in because if air pressure behind them. ...or they are too long

 

[MartDalb]

Look at this clutch drum. It has 4 notches in the center hub. Those notches drive the plastic worm gear. The drum for the brass gear does not have those notches.

yes, correct. sometimes you can just plug in the part # in google and come up with ereplacement parts and they have a part compatibility list... and the 254xp is listed.

Why not do the cylinder first? Thing is, you dont need to order any parts before your cylinder is fixed.
If you sand with power tool, go slow, and be careful, if its your first time you may hand sand around the ports.

Ive seen cylinders far worse then yours who ended up well.

Later parts......
The greek is the cheapest Meteor piston seller.....there is a lad in Latvia who sell clutch drum for 14-15€.....you can check up seal&o ring prices at a Husky dealer in Denmark, etc etc etc

Btw, post up your serial number, it is far easier to know what you're working with.

 

[MartDalb]

Been cleaning it by hand.. Hoping that will do it

 

[Tor R]

List is long....but not "that" expensive.
The bearings for the piston and oil pump etc. all seem fine, so not replacing them unless i'm told by wiser people.


MUST HAVES:
Piston kit
Seal kit (gaskets and seals for cylinder/etc)
Carburator repair kit (might as well while I am at it)
Spark plug
Fuel filter

MAYBE:
Clutch drum for plastic worm gear (is the worm gear included btw?)
New oil pump?

probleby the cheapest place you find Meteor pistons in Europe:
http://www.ebay.com/itm/Piston-Kit-...m-503503701-/400842553370?hash=item5d5413f81a

Call around to a few Husky dealers in Denmark and get price on:
OEM seals: 2 of them # 505 27 57 19
O ring: # 740 48 27 02
Gaskets: # 501 86 25 02, 501 86 21 02, 503 70 48 01
Fuel line (guess you got the old straight type): # 581 75 61 03, if its the pig tail type its # 581 75 62 01
Fuel filter: # 503 44 32 01

Plug, just buy one NGK BPMR7A

There is a Walbro dealer in Denmark, Busk & Svith, their telephone number is: 458631600, the carb kit you want is K22-HDA.
If you're only swapping carb gaskets you may consider oem # 503 54 76 01 who is a kit with gaskets only.

Clutch drum? I wouldnt bother to swap over to the new type if your drum is okey. There is two different type oil pumps to the 254, the old one with a narrow hole and the newer type with a bigger hole for the plastic worm gear, no one know exactly when Husky swapped oil pump but it happen well before the plastic worm gear arriveded.

Been cleaning it by hand.. Hoping that will do it

just make sure there isnt any alu transfer left.

holy.....nice work Tor R, I will be looking into every info you gave me here.

Am I to understand that saving money "non original" parts like seals and gaskets aren't worth it?
I am guessing by buying from a Danish Husq dealer I will be paying a lot more than if I bought some aftermarket gasket/seal package, like the ones on Ebay.

 

[Mattyo]

Tor R has done just a smidgen more of these than me

Good stuff gents

call to around 3 different dealers, none of them will have the same price, pick the dealer you prefer.
I can give you a ruffly estimate how much you has to pay for buying oem ( if its close to norwegian prices), and its kinda max price also.....
Seal, 90-110dkk each
O ring, 30 dkk
Fuel line, 40-50dkk
Fuel filter, 50dkk
Cylinder gasket, 40-50dkk
The two different gasket for the intake, around 25dkk each

Ngk plug around 40-50dkk, many who sell them
Gasket kit from your Walbro dealer, around 80-100dkk
If you go for the oem kit number I gave you it's around 100-120dkk.

Another thing I swap on those 254's is the clutch spring when I'm there, its one of the first thing I do on 242 also, # 501 45 61 01, its a 30-40dkk spring, if yours are old and worn a new spring will give you 3-400rpm better idle.

I buy AM parts now and then, there is nothing wrong with saving money, but DKK and NKR is weak nowadays and Euros, dollars and pound is high, right now it isnt such a bad deal to buy stuff from our own countries

thanks Matt for your kind words.
Hey, I pick up quite a bit learning from you also.

 

[MartDalb]

I am having a super hard time getting that damn wormgear off atm.
Can't seem to find something big enough that will allow the puller to actually grab and pull.....

considering if this might do it.... https://www.billigvvs.dk/Roer-Fitti...rt-roer-fittings--Sort-Kryds-1-2-1635603.html

 

[Sepia]

If you are using a pipe coupler, try grinding into the sides of it to give your puller something to bite on.

 

[Mattyo]

Need a 1" to 1/2" npt iron pipe union.

Grind into sides....use a pitman arm puller. Done. ...just like in that ct gtg vid

 

[Sepia]

just like in that ct gtg vid

 

[MartDalb]

update...
succes, as pictures will show, the wormgear came off.
I will however keep the tool used for it a secret, mostly because it wasn't pretty! , but off it came, in the end.

The seal has been removed as well, it seemed VERY old and crisp (if that's the right term?)

Next step.
Ordering items!


Again, I can't thank all of you in the thread enough! awesome help!

was not so bad maybe a tad over what I expected since your currency is higher then ours, but Husky Denmark may be a tad more greedy.

That pricey OEM carb kit is better then Walbros K22 HDA kit, for those who wonder this is the gasket where OEM is better:

 

[MartDalb]

now...about equipment from this point on.

The carburator, will need a cleaning. I don't have compressed air available, I can get some carb. cleaner.
Will I need to swing by someone with a compressor for the air cleaning of the carburator?
Or simply buy one....

by the way, I did NOT order a piston bearing (seeing as this was not listed, should I have?), it's not too late for it

 

[Tor R]

The seal has been removed as well, it seemed VERY old and crisp (if that's the right term?)

those old 254/262 and 242 seals is awful, its the first I swap out.
The new style seals you get is a far better design.

Clutch side seal, remember that its not mounted flush with crankcase, its 1.5mm before its flush

break cleaner will also do the job on your carb, if you also blast it with compressor remember that little screen filter, I've blasted many of them away lol

No need to purchase that piston bearing, not often there is a reason to swap them.
I've only seen one broken piston bearing out of 20 project saws, but then, there wasnt much left of that saw lol
50-100dkk bearing I guess

 

[MartDalb]

Meaning. Don't mash it all the way in. Leave 1,5mm? ☺
