setting ym2200 valves

[oddball-HT]

i just recently purchased my ym2200 and have been doing some preventing maint. and serviceing....no telling how long since its been done if any at all....great little tractor...anyhow,i pulled the valve cover off and noticed all four valves were closed and were way out of adjustment...i set them at the recommended setting from hoye,but my question is should all of them be closed at once? never seen something like this before...it is a little hard to start, is it possibly out of time? any help>>>>>>

 

[winston-HT]

Yes, on a two cylinder all the valves can be closed at once.

Are you using the compression release when cranking? Warm weather?

Have you had the injector pump off for any reason? If not, it is not likely out of time. Timing is set with shims under the pump.

Winston I saw you asked was he using the compression release when starting? Is that something that is recommended on all diesels? I have a YM2610. Its my first experience with a diesel. Thanks in advance for your responce.

All diesels don't have compression release. I believe all the grey market Yanmars do. I believe it is recommended to use it for a several reasons. 1. Diesels like the higher rpm for cranking. 2. Easier on the starter. 2. With the fast turnover oil pressure can actually be obtained before the big bang at ignition. Condition of the engine has an effect on just how long it needs to turn over before oil pressure comes up. My light goes off in 2 or 3 seconds. I have heard of others taking a little longer.

 

[live2ride2007-HT]

Thanks Winston. My oil light goes off about the same as yours. All your reasons for using the compression release makes perfect since. I never thought about any of that as I stated in previous post up to now I have only dealt with gasoline engines. I have a lot to learn. I will use it now if for no other reason but to save wear and tear on the starter.

im gonna try this for a third time,,,,i havent had the pump off,the only things ive done is changed the oil and topped off the hydraulics,added a different temp gauge,changed the oil pressure sending unit,and installed new glow plugs....any suggestions????

What do you mean by "a little hard to start"?

 

[alan-HT]

A fast spin needs, besides the c. release, a strong battery with good conections, an OK starter, and multigrade oil.

Easy starting once the c. is applied needs (besides proper flow of good fuel) the thermostart to have been engaged properly, throttle set at or near full, and air freely in and out. If that doesn't do it and the valves are right, I'd look at the downstream fuel (pump, injectors) and/or a compression test -- a bit more work.

 

[oddball-HT]

it takes 2 to 3 times warming the glow plugs before it will try to start and even then it takes so long to fire off it makes me think im going to burn up the starter...ive read where some guys claim theirs will start without heating the plugs????? it runs and starts fine once it starts the first time, any suggestions....

 

[Norm-HT]

Air filter? Fuel filter? Bled fuel lines? Good fuel? Most Yanmars don't even have glow plugs. I'm surprised to read the YM2200 does.

 

[winston-HT]

You installed new glow plugs. Have you checked to make sure the glow plugs are working? (getting juice to them)

You said it runs fine once cranked. Any continuing smoke or blow by out the crank case vent?

 

[oddball-HT]

it has a oil bath breather with new oil, i have already run about 3 tanks of fuel thru it, the first tank i added some diesel injector cleaner to it, i have bled the lines while turning it over at the pump and at the injectors....it did have some blowby until i set the valves.....judging by my feeler gauge i would say they were close to being around .080 before i set them and now they are set to .007.....if i remember right hoye says .006-.008....am i headed in the right direction. i havent changed the fuel filter yet, still deciding what to do about the shut off valve on the bowl its stuck and i cant turn it off.

 

[winston-HT]

Have you checked the new glow plugs to make sure they are getting juice to them? That is where I set my valves.

 

[oddball-HT]

yes they are getting juice....its just nerve racking that its hard to start the first time....this is the only problem i have found with it..

 

[oddball-HT]

i recon i need to get a compression tester and check that next.. it only smokes when i put a strain on it and hasnt burnt any oil yet.

 

[Norm-HT]

Forget the compression test until you replace the fuel filter, bleed correctly, and try starting without air filter, and without muffler. Compression test can get pretty involved.

 

[oddball-HT]

im gonna go to my local parts store and just see if i can get lucky enough for them to match me a fuel filter....i also went ahead and ordered me two more new injectors,,i was getting juice to mine and they are new but whats to say that one of them isnt defective...im going to go ahead and check the comppression on it while im changing the plugs..what would be avearage compr. for it to still be in tolerance...

 

[Norm-HT]

You should see 500+ psi compression. Are you confusing injectors and glowplugs?

 

[alan-HT]

I've never seen a replacement filter element outside of a yanny dealer but you might be luckier than me. And I think a standard compression tester won't mate without a Yanmar adaptor, also available from a dealer.

 

[Norm-HT]

Either a NAPA, (WIX), 3262 or 3263 will work. Compare to yours. A Yanmar compression test is a big undertaking for the inexperienced.

 

[oddball-HT]

a local mechanic told me instead of pulling the injectors for now that i should get the right metric fitting that fits where the glow plugs go and adapt to a pressure gauge since im changing them again anyway. can this give a good enough reading for compression or do i have to pull the injectors?

 

[oddball-HT]

and about the filter, one of our local parts stores stocks several tractor parts for all kinds and for autos as well so i should be able to match it if the numbers above dont.

Probably wrong but I'm thinking your glow plugs screw into the intake and not the cylinder??

 

[oddball-HT]

on my 2200 they screw into the side of the head right below the injectors...pulling the injectors wouldn't be a bad thing that way i know they will have new orings on them when i put them back in..

I understand where they screw in but are you sure that part of the head is not just the intake passage?? I just can't see that long glow plug sticking anywhere in the combustion chamber. New o-rings sounds like a good idea.

 

[oddball-HT]

thanks winston, thats kind of what i was wondering too. im just going to pull the injectors and do it that way and replace the orings while im at it. thanks for your insight on this tractor..

 

[winston-HT]

Not sure we are understanding each other. I am saying I don't think you can check compression using the glow plug openings. I believe you will have to pull injectors to check compression. Again, I may be wrong, won't be the first time. <E></E>

 

[oddball-HT]

sorry for the confusion,,im going to go ahead and install the new glow plugs and then pull injectors anyway, check the compression and if its close to the 500, then im going to install new orings on them and put them back in. i have noticed that one injector is seeping a little anyway..

 

[oddball-HT]

just want to say thanks to those that replied on this post..i didnt fool with checking the compression. i took the advice and changed the filter even thou it didnt look dirty,and replaced the fuel line from the bowl to the pump, then bleed all the lines like hoye states to and installed the glow plugs and dam if it didnt start way more easier than before. you guys know what your talking about. i will sure to contact yall if i have any more problems.

 

[Brackers26-HT]

pull the inspection cover off of the fly wheel.
youll see 1tdc and spin it around and see 2tdc
the #1 cylinder is closest to the flywheel.
adjust valves i did mine at .006
then i usually crank it over for a bit and recheck.
can also pull the injectors or glow plugs to release the compression just making it easier to spin around
