Yanmar 1610S Wet Liner?

[timddeb-HT]

I'm thinking of buying a secondhand YM1610S. Thing is I have a thing about wet liner engines as every one I have ever bought has cost lots of money, and sometimes still been scrap. I've been told some Yanmars are wet liner, does anyone know if the 1610 diesal is?
PLease do not tell me "Yanmars never go wrong" or such I always end up with the exception. I am a reasonable mechanic but never want to go through the dissapointment of trying to fix a wet liner engine again. Ever! <E>:roll:</E>

I'm pretty sure that your issues with the wet liner engines have probably been due to the maker of the engine &amp; not the style of liner (or sleeve). Historically the Yanmar sleeved engines (wet or dry) are amazing. If you don't overheat one or do something stupid you can easily see 8,000, 9,000 or more hours out of one before a rebuild is needed. Then, when you finally have to rebuild you can just replace the liners and your off again without a trip to the machine shop.

The 1610 is one of the few Yanmars that do not have replaceable liners at all. not wet or dry. We did have liners put into a 1610 that we recently rebuilt though for around $200.

Either way, the 1610d is one of my favorite tractors. It is just the right mixture of small frame size &amp; power.

Aaron thanks ever so for taking the time to reply. My experience with wet liners comes from many different makes, inlcuding but not limited to Fordson, Peugeot, Citroen, (same really as Peugeot). I have probably rebuilt around 10 or so, and to quote the song, won't get fooled again. I just scrap the vehicle. I know thermodynamically it is superior most of the time, and there might be other advantages. I don't care, I don't want a wet liner engine. I note you say unless you do something stupid. Well things happen to me,like stones through rads at high speed, I was asleep and the driver didn't notice anything till I smelt it. I have sleeved dry bores when pistons try their hand at ploughing. I'm not sure from what you said if it is originally a wet liner engine or not, and hate to be perdantic but I really will not willingly get involved in a wet liner engine. Are the bores cast into the block or are they placed in? <E>:roll:</E>
I might be a little bit paranoid, so would really appreciate knowing.
The tractor looks about right for what I want to do, so only need to clear this little question up.

I think the industrial diesel wet seeves are going to be a little different than those you mentioned. <E></E> Either way, the 1610 does not have them so no need to worry. I believe the sleeves are just cast into the block.

What is a YM1610S, and what kind of problems have you had with wet sleeves? I have not heard of any problems with them in the US.

Apparently in the UK S means two wheel drive. Go figure. Wet sleeves is where the manufacturer has the cylinder bores as sleeves which they push into the block, with a machined step and seal at the bottom of the bore. You get really good even heat dispersion as the sides if the bores are now uniform, unlike you get with a casting. So from a performance point of view it's a good idea. On things like cars where there is a limited life it can make sense. (but not to me). If the block is mistreated in any way, like weak antifreeze, overheated, cracked and twisted, or just plain aged, the seals fail and you get compression in the water, or water in the oil, or both. From experience whatever the manuals say, and no matter how careful you are, there is no long term fix once this has happened, short of welding them in or some really whizzy glue, neither of which I have managed yet. <E>:x</E>

Sounds like you have been buying very high hour or badly abused tractors. Most Yanmars are sleeved and we just don't hear of that problem in the US.

 

[timddeb-HT]

Nope, just lots of expereince. I've learned so much from my mistakes I think I'll make some more. <E>:lol:</E>

Aaron thanks, bought the tractor, working like a dream <E></E>
