Yanmar YM165 Oil Capacity

[bedrock61]

I'm glad you got it. That seems like a very fair price; I doubt you will ever lose any money on it. Might even make a few hundred dollars.

Yanmar did make a front end loader with a full lower support frame just for that tractor. It was a dandy; If you can find one, snap it up. That particular loader hydraulics were designed to be independent of the tractor's 3pt hydraulics. It is designed to be run off an accessory hydraulic pump that bolts in front of the frame and is driven via a flexible coupling to the crankshaft pulley. Driven like that, it is a surprisingly powerful and fast loader. Well matched to the tractor.

The YM165 was an update of the venerable old YM155D. For the YM165, Yanmar took their popular YM155, fixed a few things that needed attention on the 155, painted it red instead of green, bumped it up one HP, and sold it for the same price as the 155 it replaced.
I wish more manufacturers would update popular models in that fashion instead of always coming out with something new.
As a result, the YM165 is about as rugged and reliable as something mechanical can be.

But since the YM135/155/165 all had the simple and archaic thermosiphon cooling system, you have to pay special attention to cold weather work. Follow the thermosiphon instructions exactly as regards antifreeze percentage (50% ethylene glycol & 50% distilled water) exactly, and use the block heater for a few hours or even overnight before starting it in cold weather. I would usually throw a blanket over the hood too, because mine lived outside in the wind.

I'd use any good multiweight motor oil that is rated for diesel engines. In mine I used Shell Rotella T4 type 15w-40. The Shell Rotella T5 and T6 types are even better, but more expensive. I think both Wallmart and Home Depot carry those oils now. This type of diesel uses the oil to suspend abrasive soot particles - but oil can only hold particles until it gets too many - so you should change the engine oil and the filter every year.

The only shortcomings I can think of for the model are that water tends to get into two places. So you should take care to cover the fuel cap and the steering wheel center if you leave it outside in the snow/rain. And if you use it in deep water, take the brake covers off every year or so and let the shoes dry out. The factory brakeshoe vents are inadequate in the wet.
Enjoy!

Thanks for all the good info! As for a block heater what are my options? There isn’t one on this engine. I have read the 2 bangers don’t have anywhere to mount one...thanks again

Nonsense. We all have block heaters. Your's might even have one already - the cord is detachable and easily lost.

Of course they don't absolutely have to have a block heater if yours will start without it in the cold. Although heating the block up before starting has to be easier on the engine.

There's a removeable freeze plug on the center of the left hand side of the block. You unthread that and replace it with a short flat freeze plug. You want to use one specifically made for short clearance blocks like Yanmars have.
If you don't already have a block heater there, there are lots of people online selling Yanmar parts. One of the best known is Hoye Tractors:

Sometimes the removeable freeze plug is hard to unthread. Only do it with the engine well warmed up and sure that you have the proper tools - like a tight-fitting SQUARE HEAD socket for your half inch drive socket set.

On the Yanmar forum there was just a long thread on taking out the freeze plug and putting in a factory block heater.

BedRock, you and I are right now in the Oil, Fuel, and Lubricant section of the General Forums on TractorByNet. There isn't much Yanmar info in this forum. But if you go back to the list of various General Forums and go down the page you will find the Brand Specific Forums. Go down until you see the Yanmar forum- it's near the bottom of the list - and you will find about half a hundred people at any time of the day or night talking about vintage Yanmar tractors. If you can't find it, use the link I posted in message #7 in this thread.

Post your question there and stand back!

Here's a photo of the block heater on my YM165D.

They make magnetic ones if you cant find a good freeze plug style one. If it starts fine with just glow plugs i wouldnt mess with a block heater in anything above 10* or so.
