Ty 295 parts breakdown

[Tdog50]

Hi folks

Well I started noticing antifreeze in my oil. A little bit at first but now after sitting for a couple of weeks,alot. Would like to get my hands on a parts manual or some form of engine breakdown so I can start investigating my problem and order parts. Any help would be appreciated.

I would think Tommy at Affordable Tractor.

These engines are prone to blowing head gaskets and oil in the coolant is a classic symptom. I replaced mine without a manual, just started taking pieces off until the head came off. As I recall I took off the valve cover, valve train and loosened the head bolts. The water pump had to come off to get the head off, which necessitated taking off the radiator. I undid the hood supports to get it out of the way. I left the intake and exhaust manifolds on the head, just hoisted it in place, removed the old gasket and put the new one in.

The only parts needed were a new head gasket and gasket for the water pump. The gasket I got didn't fit my water pump so I ended up using gasket compound. I also replaced the thermostat while I had it apart, which meant a new gasket. And the little rubber donuts that hold the radiator were pretty distorted so I replaced them too, they were a buck apiece.

The only tricky part of reassembly was torquing the head bolts properly. They have to be torqued initially, and then run the engine to operating temperature, let it cool, and torque them again. Then do it again after 50 hours. Each time you torque them the valves have to be adjusted. My recollection is that the valves moved significantly when I retorqued, which indicates that the head gasket compressed substantially.

What are the torque specs on the head? And what are the valve clearance specs? I am about to get into one.

Thanks Quicksandfarmer. Pulled the tractor home today Tommy didn't have a gasket or a breakdown but pointed me in the right direction. Just waiting for the gasket and the weather to cooperate. -20 celcius here right now.

Ok, so the weather has finally warmed up enough and the tractor is on firm ground , in a neighbours unheated garage but on a good cement slab. Will start pulling pieces of tomorrow. got a head gasket guess I will know as I go if I need to dig deeper. Maybe I will try to take the oil pan off first and pressurize the cooling system. Not sure if I can pull the pan off without splitting the tractor but its worth a try. Just the fact that there was quite a bit of antifreeze in the oil after sitting for awhile has got me thinking cracked block so a mechanic friend of mine suggested the coolant pressure test. Any one have any toughts on this. I am mechanically inclined but not a mechanic.

I would check with Tommy from Affordable Tractors. Some of the Chinese engines have bolts into the sump from inside the bell housing which means you have to split the tractor to remove it. A simple phone call could save you a lot of trouble. He provides great service.

Thanks for the reply Zonta223. Got the engine stripped down this morning should be able to pull the head off tomorrow. Will go from there. Can't use it this way anyways so might as well get to the bottom of it. Will call for parts as soon as I'm sure . Any input you guys may have is greatly appreciated.

On my Jinma removing the oil pan is just about the biggest job you can do. You basically have to remove the engine. The oil pan is bolted to the bell housing and the front axle. You have to split the tractor, then you have to lift the engine and disconnect the front axle.

Some Jinmas have an inspection port in the bottom of the oil pan, which is good if you want to replace the oil pump.

A blown head gasket can put plenty of coolant in the oil. I would replace the head gasket and then pressure test before taking anything else apart.

Did the head need much convincing to come off ?. Can't get mine to budge. Will have another look to see if I forgot something.

I put a lag eye into a rafter and lifted it off with a come-along. So it wasn't nothing, but I didn't feel like I was about to pull the building down or even pull the lag out.
