Whatabout the needed pressure test pressure by the way
- the workshop manual says "Pump up the pressure to 80
kPa (0,8 bar)" - but that is less that atmospheric pressure
(1 bar) isn't it? - sounds strange to me - or is it additional
pressure as compared with atmospheric "base pressure" -
(in the latter case it should be similar to sort of vacuum it
instead I suppose - would be similar pressure difference
...).

I think it is 0,8 bar over athmospheric pressure

 

[palbin]

Yeah - must be I think I just realized (learning
things by the minute at this forum ) - otherwise
one couldn't mesure it, simply ... .

 

[pantelis]

What is your opinion about pressure an vacuum? Is it enough if tested with vacuum or is it neccessary to test something with pressure too?

Plain vacuum pump/gauge is much cheaper but I hesitate to buy if I later needed pressure too.

Mityvac MV8510 would be great, but 86€ is quite lot of money for something that is needed rarely.

Watch this cost 39 euros + 10 shiping world wide. i have two of them work good the seller is from Germany

Thank you very much for this tip - I was too un-
knowledgeable to search myself for EU alternatives
to the stuff the US people purchases ... .

 

[tonil76]

That is good hint. I have browsed ebay for some time, but haven't found that.

 

[tonil76]

Ordered one. I think it is worth 50€. Important tool with saws anyway.

Thanks man - but with that price (700 spänn) I think it is bet-
ter for me to buy the "real stuff" - perhaps I wait to hear what
our Finn collegue finds out about his purchase - or I buy same
as him - or buy something more "labeled" - after all I have (I
think) 16 saws building up service needs by the minute ... .

It would be more sensible to have them serviced by a well rep-
uted Hva service near by (whom also do other brands) - but it
is WRONG not to do it yourself ... .

The Mityvac MV8510 seems to be readily available at
ebay.uk for 90 EUR or so - but that is just the press-
ure thing itself, then - but no assecoires needed to co-
nnect "the thing" e.g., to a spark plug hole ... ?

Stihl OEM about 400 euros '' the real stuff ''

As far as the plug adapter, I took an old spark plug, knocked the electrode out from the bottom up. Then cut off the washer and replaced with an o ring for an easy hand tight seal to cylinder. With electrode out you can decide on what type of fitting to add for your hose. A hose can go right over the od of the plug also.

(Qoute) Stihl OEM about 400 euros '' the real stuff '' (/Quote)

Does this kit do everything in terms of pressure and vacuum
testing for both Stihl and Husqvarna chain saws without ad-
ditional assecories, then, or is it just for Stihl?

The corrseponding kit for Husqvarna seems hard to find, but
I guess it must be out there somewhere? (Perhaps it has been
terminated because new saws are "electronic diagnostic" using
e.g., this kind of stuff

http://www.ebay.com/itm/Husqvarna-J...396?pt=LH_DefaultDomain_0&hash=item1c442cce64

?)

 

[decableguy2000]

Husqvarna doesn't sell a kit as far as I know. I have ordered the parts as needed for each saw. The Stihl kit is for Stihl's only. Check your in box. That Ebay item is for the AutoTune stuff.

 

[palbin]

Thank you very much - very kind of you.

Yeah - one could probably fit a bicycle air-valve, say,
possible with some additional adapters (to get suitable
length), to a spark plug nut (without electrode etc), by
mean of e.g., epoxy - and get something quite air tight
that would work for pressurizing cylinder etc by means
'of ordinary bicycle pump (with manometer) ... .

Edit: I will make one the day after tomorrow ... .

Still - if one find the saw doesn't hold the air as it sho-
uld - it remains to find where it is leaking - and unless
one submerges saw in bath tub ( ) that doesn't seem
to me to be a trivial problem - or do one just sort of lis-
ten for leaking air?

 

[Big_Wood]

i just bought an adapter from my local auto parts store. think it was $5 and had adapters for different plug hole sizes.

You can pour or spray some soap water and bubbles indicate the leak

 

[palbin]

Yes thanks!

I suppose leaks can be at

1) inlet
2) cylinder foot
3) decompression valve
4) crank case halves (but this shouldn't happen, should it?)
5) crank shaft seals

Here the first two could readily be tested by soap water
I guess - thanks!

As for number 3 - I know that is not the fault!

As for number 4 - it should not happen ... .

And if just number 5 remains - which I guess cannot be rea-
dily tested by soap water - if it leaks - must that simply be the
culprit ?

Sorry for all the questions ... .

Edit: I just made a visual inspection of the cylinder foot gas-
ket - and it definitely was "wet" - especially on the lower side
(which I guess haven't had time to dry up as the upper side
- which was also just a liottle "wet" at one place) - that is not
correct I suppose - could be the culprit?
