Re-torque Head bolts on 2210

Smoody · Mar 14, 2012

I will take a look at that injector, doesn't appear to me that rust is down inside the outer part of the injector, I see where it looks that way in the photo though.

As far as any sealant spray, nothing is flaking off anywhere that looks like any type of sealant, but I am not sure what your referring to. I believe that is just grease and dirt, I will take a warm rag this evening and see if that wipes off easy.

HF did not have a 22MM deep socket by itself and I have no need for the complete set at $37. I will stop by Lowes after work.

The "sealant" he was refferring to is a copper spray, its in a spray can. I remember it from when i worked at an auto parts house. It was for head gaskets but dont remember the circumstances it was used under? Maybe reuseing an old gasket? Anyway you DONT want to use it i was always told.

And at Lowes your going to pay between $5 and $10 for that one socket!! Do you have a pawn shop on your way home? Many times you can buy a single socket out of a big box of randoms for a dollar or two.

my local HF said they have a truck coming this evening and may have more, so i'll check with them tomorrow.

I wiped down the block yesterday, that was just grease/dirt on the gasket, it wiped right off. by Monday I will have results as whether re-torquing solved it, if not I'll replace the head gasket after I get my food plots in.

I wouldn't loosen the head bolts before tightening. That might let water seep where it wasn't leaking before. I would just start at the center and work outward as specified in the service manual. In multiple stages, if any are significantly below spec. Don't overlook the one hidden in the intake manifold. (If its like YM2000).

Also this would be a good time to torque down the rocker shaft pedestals, then check the valve clearance. Tightening the head bolts could affect the clearance.

Smoody · Mar 15, 2012

How many head bolts does my 2210 have? I just see 2, are the rest under valve cover

careyo63 · Mar 15, 2012

Here's a hint. There not on the side of the head

Yes! thats why I said your need a 17MM.

Smoody · Mar 15, 2012

Duh, you did say that, sorry about that. The outside ones look like they would be hard to move, could the torque wrench actually click but the bolts not move if they are rusted bad, thinking I should spray them down

Is the gasket for valve cover reusable?

California · Mar 15, 2012

Assuming that is near identical to YM2000, the valve cover gasket is rubber and is re-usable. I put RTV sealer on the cover side of the gasket only, to help fill unevenness and keep it in place while I install it. I don't know if this is needed.

6 bolts? I think. That makes sense for a twin. If the torque wrench won't move them ... good enough.

Zork · Mar 16, 2012

What are the torque specs for your head bolts? There may be two sizes of bolts requiring two difference values.

The torque value may be misrepresented because the bolt is tight and that is why some loosen it first. If you choose to loosen the bolts first remove the radiator cap to relieve pressure.

I had to spit my chewing gum out and stick my tongue out in order to muster the strength to torque mine, mainly because my body and wrench position were awkward. The threads to the head bolt are down in the block so the lubrication would need to make it all the way through the head.

Anyway, perhaps you should enlist some help by a local person with this. Start asking around town because you may have to remove the rocker arm rails to do this and that will require a valve lash adjustment.

Yep, the wrench is going to click unless you loosen first. But loosen only one and re torque it before moving to the next one.

Your gasket is some kind of rubber material. If it is old it has lost some of its pliableness. If it still protrudes out of the cover a little it would probably re seal. New gasket is not that high though, but I feel impatience here.

I was told the service manual for the ym276 is the closet I would find to the ym2210, I now have the ym276 service manual but if anyone knows the exact specs for the 2210 please post them, I am not sure if it has two different sized head bolts, 130ft/lbs I was told is what they need, the ym276 reads the valve clearance in .008, is that the same as the ym2210?

winston1, not so much impatient as wanting to make sure I have whats needed before I start, I got plans for the tractor this weekend and didn't want to need a new gasket and be down until one gets ordered.

Looking at the rocker arm removal and installation in this book it looks pretty simple, I think I could tackle this myself.

Straight out of the ym276 service manual
Cylinder Head Bolts and Nuts Torque
Initial 29 ft-lb
Second 58 ft-lb
Final 94 ft-lb

so where are you guys getting the 130 ft-lb from?

careyo63 · Mar 16, 2012

My bad had to check It's 133 Ft.Lbs not 135. I doubt your torgue wrench is that accurate to worry about it. A couple pounds to tight is much better than not tight enough. IMHO. You have the same motor basicly as the 2tr20. the 2210 isn't that much different even on the cylinders. The Red 2000,240,2210 all use the same piston 90mm. the only difference was the first GRN 2000,1900 was 88mm. How they increased the Hp. I do not know exactly on your model but would have to be in the head valves and inj.

Zork · Mar 16, 2012

The difference of 133 # and 94 # is significant enough to wait until you get additional confirmation.

Zork · Mar 16, 2012

Look at this- This seems to have sites that NEED Spec's too and does not seem promising at second glance but I don't have the time to go deeper. Doesn't JD have a 2210 yanmar?

*****UPDATE: BE CAREFUL ON THIS SITE I DID A FEW SEARCHES FOR OTHER TRACTORS AND IT SEEMS THE INFO IS DIFFERENT BUT THE PAGES LOOK THE SAME.
Yanmar Tractor 2210 Specifications compiled pdf, doc, ppt ... ********

130 pounds according to this site:

Head Gasket YM2210 Torque Specs

California · Mar 16, 2012

As for the 2210 engine (only) - I think it is near identical to the 2-cyinder 2TR20A used in YM2000 and YM240. So the YM240 service manual from Yanmar-USA is the best available documentation.

I'm just guessing but it seems like the 130 ftlb spec is for the six large head bolts on these big twins, while that lower number you found is for a 3 cylinder engine with more, smaller bolts. Looking through Hoye's online catalog might confirm this difference in bolt size.

Somebody out there must have researched this for YM2210. Anybody?.....

Zork, I don't think there was ever a Deere version of this 2-cylinder Powershift Yanmar, and Deere's 2210 is unrelated to it.

clemsonfor · Mar 16, 2012

ill try and remember when i get home to get my ym240 service manual and see what it says.

California · Mar 16, 2012

Carey nailed it. From my YM240 Service Manual:

Head nuts Qty 6, 130 + - 3.6 ft lbs
Rocker arm support, two, 58 ~ 72

And the 130 posted by Zork references a post elsewhere by 'Danny', I assume our 1Danny, who is a specialist in YM2210. If Danny said it, I believe it.

Did anyone go look at the pdf files that Zork referenced? Are they worth downloading?

Beat me to it was about to get my manual but figured id check to see if this was sorted out yet.

Neat 1500 · Mar 17, 2012

i dont think i would be comfortable enough to crack the head bolts undone to retorque them on a head gasket that is possibly 30 yr old or more. just tighten them up.... yes but not undo and do back up especially if it were for the minor leak it has. if it were major and it looked to require a gasket change anyway then yeah do it, nothing to lose. the bolts probably will not want to retorque @130 anyway without cracking them somehow.:confused2:

Smoody · Mar 17, 2012

It seems it's 50/50 whether to loosen then retorque vs. just tightening the bolts, I used tractor 4 hours today and it ran fine, no overheating etc. The oil does not show any sign of water contamination, I may just keep an eye on it and just change the gasket in a few months. Since cleaning the grease/grim off the block I didn't notice any signs of leakage allday.
