Yanmar head gasket

[jefferycks]

Hi, I am currently looking for a head gasket for Yanmar engine. Does anyone know this head gasket is for which engine model?

 

[winston1]

No engine model or tractor model??:confused3:

If you can't find an engine model number we might be able to help with a bore diameter and distance between cylinders.

It appears to be for a 3 cylinder engine.

How about some more photos? The whole tractor, engine id plate, head and valve cover, maybe the dashboard. Or is it in a forklift or something?

So far that gasket could be anything.

It's similar to the 3T engine family. The 3T80, 3T90, 3T84 and such.

hi hoye tractor,


i have attach a picture for your convenient. the diameter of the old head gasket was about 73.5mm. thats all the info i have at the moment

 

[bmaverick]

Well, he did say it's a Yanmar "engine". Maybe it's industrial or Marine and not even a tractor.

Yanmar Tractor Parts HEAD GASKET_ :confused3:

Fits a 1610 and I don't know what else. 3t75u

My guess is that he is trying to buy one off ebay or something and the seller does not know what its for?? and he does not want to give his link away fearing someone may snap it up?

Why else or for what other reason would you not list the tractor even let alone the engine ID ?? wwith that he could just buy from one of many sources for parts maybe enve Yanmar USA if its an american model? Or Hoye tractor would probably be the best and fastest...then you have Frederics???

This is a strange post

That's why I replied asking if the engine wasn't a tractor but actually Marine or Industrial. Yanmar makes a 3T80LE that can be used in a Firetruck as a pump engine or other applications too. If you have a Yanmar YM2500, YM2610, or John Deere 850/950 one could use the 3T80LE as a drop-in replacement long as a few minor parts from the original engine are moved over. Thus, you have let's say a 1981 tractor, but with a 2015 engine. lol

OK, I've taken both pixs and flipped and resized to compare.

The original


The 3T75U


So, Yanmar OE p/n 121470-01332 should be the head gasket. The prices range from $35 to $100.

Hoye .......... $43+shipping.
Fredricks .......... parts catalog on page 17. call.
Stevens Compact Tractors .......... $74+shipping.

The distance between the Cylinders are way off. Twice as big on the Old HG. than the 3t75u new one. I don't believe that's it. Maybe the Same Eng. but with a larger Cyl. Bore. Jefferycks is showing 73.5.mm so that will be easy to check if it's the correct one.

Looking at a few historic threads on the Yanmar forum, California and a few others understood that taking lets say the 3T75U and compare the numbers. 3 = number of cylinders. T is engine series. 75 the cly bore or piston size. U for the variant of that engine.

75 and 73.5 in millimeters is tight. Thus, I would conclude that the HG could be the match.
