Y380T Engine Specifications

[ToolManRick]

I've had my Jinma (Nortrac 204C) for a few months now. Amazing how fast the hours accumulate. Anyhow, the manual I have contains specs for the 385 and 290 engines, but not the 380. My question is... Is the valve clearance the same on the 380 as the 385? Northern Tool has told me yes, but I'd like a second opinion. If anyone can enlighten me or provide a link where I can download the Y380T specs I would truly appreciate it.

P.S. So how's everybody doing? It's been awhile since I've checked in on the group. (Busy piling hours on tractor)

I have been told, the only difference is 5mm less bore. Everything else is the same. BTW, check your hour meter. Others have reported having an hour recorded, but actual time transpired is less.

The correct valve lash for Y380 engine is:
Intake .20-.25mm cold
exhaust .25-.30mm cold

To the best of my recollection this is the same as Y385.

Good idea JohnS on "clocking" the meter. I'll try it tomorrow when I pull some logs out of the woods.

The valve clearances you give bluechip are what's in my book also. I don't have to do anything with it for a little while, but appreciate the input. Thanks guys.
