My 'mad toy' this year is a '99 JD 5210 2WD that's in pretty good shape o'all but runs a bit lumpy to my ear. It's my fourth 3 cyl (not counting the old crane's GMC 3-53) and doesn't seem to be running evenly on all 3. Not horrible or scary, just not as smooth as I'm used to.
Meter hours (digital) are low if it's to be believed, but I won't be happy 'til I've checked the valve lash and injectors. All I'd need is the spec for the lash if there's nothing funny to getting the cover off & at 'em, but injectors would have to be pulled and tested before I'm satisfied that I've done all I could. (anything tricky to getting them out?)
Interestingly, new injectors seem to be half the cost of those for my cars (Buick 3800s in Chevies) and I wonder if I could have the OEMs tested for <$40 per, so just replacing them could be an option and a matter of being confident that new would be in spec OOB.
I'm no stranger to engine service, rebuilding, etc, and with a good service manual (OEM, I&T, etc) I'd tackle anything, but I'd like to check this stuff while shopping for one that doesn't cost more that a some 3PT attachments. Do I need much help or advice thus far, or is my usual over-caution making this look more complicated than it really is? (expect me to test compression before & after lashing if adjustment is needed ...)
Thanks in advance for all comments! tog
