Broke a valve

[blackd]

Well, the old girl sucked a valve. Top of valve broke off so dropped down, but don't know if it did any damage to piston. I haven't pulled the head as yet. Just pulled the valve cover. Anyone have any experience with this?

Engine is the 3TNB84-UA. If necessary, anyone have a replacement head?

We have rebuilt heads for those available but they are expensive. Hopefully you won't need one.

Update: The valve retainer clips came off. Valve dropped and beat the beejeebers out of the top of the piston and pieces scored the cylinder walls.

So the best I can determine to repair, is a head/valve job ~$200 + parts, new sleeve and piston, $ price TBD.

Anyone have other suggestions/knowledge? Any added parts recommendations if I choose to do the piston?

You might want to check the valve spring tension or replace the spring before putting it back together. Either the keeper broke or the spring was not holding enough tension to keep it on.

I hope you dont need a new sleeve. The F series do not have sleeves. We should have the other parts though.

Well, that "no sleeve" message was disheartening. It was a good news, bad news, good, then bad news again day. Good was there is a mechanic in the neighborhood. Bad news, well you heard it above. That dramatically changes the labor dynamic.

I looked around for a replacement machine, and am leaning hard to an Orange. I can get a BX2350 (last years model) for a little over $13 with turfs, mid mount 60", FEL and loaded tires.

So I have a used FX24D fix-er-upper if anyone wants to bother. I also have a 72" KK finish mower, 50+ inch rough cut mower, rear bucket, and home built FEL which mounts to the FX24 frame.

The little Orange my friend bought like you described was too low to the ground to run a regular sized post hole digger and the turf tires on his 4x4 do a lot of slipping. He still uses his Craftsman to mow.

You can get .010 & .020 over size pistons.

Well, after much research and anguish, I pulled the trigger and bought a --- wait for it --- a MF GC2400. What I determined in the research was, there is very little difference in specs between these small tractors. So, the major differences were base price, (Deere is dear), local service (MF is the next closest dealer after Deere), and financing (MF has 0 down, 0% for 72 Mos.)

With that financing, I almost bought the TLB version, but just couldn't justify the price difference.

Bottom line: $14,400 + tax for the GC2400 with FEL, 60" MMM, R4 tires loaded, delivered to my door.

Orange was ~ $400 cheaper W/ 36 Mos 0% financing. Blue was higher, but never got to the bottom line same financing as orange. Green was $3K higher same financing as orange.

Bottom line is that it is a contract tractor (made by one company, marketed by a completely independent company under it's own name). Look for parts for the last contract tractors Massey had made. When the contract ends, the parts supply will begin to end. Contract tractors historically begin to lose parts support when the manufacturing contract ends, simply because there are two different companies involved.

Facts are facts. Feel free to ignore my posts if they're not warm and fuzzy enough for you. We get the calls from disappointed, disgruntled, disillusioned tractor owners. As often as not they then vent their frustration to us for not being able to help....despite the fact that our website is very explicit about what we have parts for. Even if they are polite, the fact remains that in many cases they are still stuck with a tractor for which they cannot get a part, or for which they will have to pay an exorbitant price to get the part from Japan.

Update ?final? Went a little deeper into the engine along with the mechanic up the road. He asked just two questions: 1) is the block cracked? 2) After feeling the score mark, have a flashlight?

Answers: Yes and yes. !@&#%(^#^&%@^%$. Not that it mattered that much, but it does take away the option of fixing her at a reasonable cost. His recommendation: sell it as a parts tractor.

So the new MF GC2400 looks like it was a good decision.

Wayne, thanks for the advice. I know about the contract issues with the sub and compact tractors, but, that really isn't much different than having a Yannie, is it?

 

[LMTC]

Yes, it is dramatically different. Our nearly 200 page catalog of parts for Yanmars is from AFTERMARKET suppliers...their ONLY interest is profit from selling parts, so they will never quit supplying parts for the reasons contract manufacturers do...those reasons are primarily 1. their contract ends with the company marketing the tractor and/or 2. they have an interest in seeing the tractors become obsolete to push the owners into buying a new tractor.

The grey Yanmars probably have better parts support than any other tractor on the planet in the same age range.

Iseki doesn't sell parts for the tractors they make for MF (except to MF) and when MF no longer markets the tractor, they will likely have limited interest in stocking parts (inventory costs money), and that interest will get less with each year that goes by. This is the general historical trend of contract tractors. That's not a doomsday scenario, but it's not as bright as it could be either.

I'm sure someone will point out some obscure source from which they can get an Iseki part for the current made-for-MF tractors, but even so it would be the exception that proves the rule. There is no organized easily accessible supply chain for those parts other than MF. You'll be fine for a few years, but I wouldn't want to have to find a major engine part 10 years after MF quits selling that tractor.

Thanks for the reply. Need an FX24D parts tractor?
