Cylinder Leak Down Tester

Recommended Posts

oliver2-44

I'm thinking about buying a Leak down tester. Looking online they range from $29 to $200+.  Harbor freight sells a Pittsburg brand one for $39. And several other companies sell that same looking one (Different names) for $29 to$49:  There is an OTC brand one for $&9 and $199.

 

So what do y'all use?  

Does anyone have the Harbor Freight one?  I'm a little skeptical l, but like the price for the little bit I will use it.   Of course if it's not accurate it a worthless .

I use the OTC 5609.   the only complaint I have is with the hose itself... there's not much to "grab" when threading it into the plug hole.

I have had one for a long time there is no marking on the instruction sheet as to brand and i forgot where I got it but I am sure ididn't pay over $100.   Each band Low moderate, high is about 30% so the actual reading isn't terribly important.  finding out where the air is going is what is most useful then you now you have a valve problem or a ring problem.

      Hey all!
       
      Replacing the drive belt on my 252-h. Anyone know the torque specification for the center screw when I put this pto clutch back on? I know it was on there tight it took a minute for the impact to break it loose. Thanks!

      Hey all. I have a Electro 12 with a factory belly blade. It runs* and drives. I had used it to grade my driveway the last 6 yrs. Having moved I'm looking at my options on storing it or selling it. Frankly I have no idea what it is worth. I watched "ISaveTractors" video on 5 things to do with a new to you wheel horse/12hp kohler. (When i got it 6yrs ago) And went thru and did the adjustments and replaced the parts mentioned. It has been a good strong tractor for me until around July of this year. (2023)
      *Around July it started dying after running 20-30min. I replaced the carb (Chinese Amazon purchase) with one from isavetractors web site. That seemed to help it idle smoother(the old carbs jets wouldnt adjust), but it still dies at around 20-30min.
      So I've got 2 questions. 
      1. What is it worth? (As-Is) and
      2. What do I need to do to fix it? 
      Thanks yall!
