I bought a 175 diesel with loader a few weeks ago. Yesterday I was heading up a hill and it shut off. It has fuel but maybe not enough and it looks like the line from tank is towards the middle. I added fuel and tried cranking it but it just tries but wont turn. Do I need to bleed air out? And if so what is the easiest way to do it? Im new to tractors but excited to learn about them...
 
My deisel 65 has about 5 or 6 points at which to bleed out the air, first 2 are the bolts on top of filters and then upper and lower on injector pump and then the injectors.You need a manual for your 175.
 
hi, I am not familiar with perkins diesels, but there should be a hand pump, Try using the hand pump, pump quite a few times. Then try to start. You may be able to push the air out with just the hand pump.
Not being familiar with perkins, but the fastest way I always bleed a diesel is by loosening one injector at a time and pump, get fuel then close injector, then go to the next injector untill all the cylinders are done.
 
Like 2tractors said, you need the manual. There's a specific order you have to bleed things in.

If you don't follow the correct order you can pump the hand pump all day and it still won't start.
 
Thanks for the replies. Tim what do u mean by a hand pump? Something that is already there or something to buy?
 
You should have a fuel lift pump mounted on the one side of your tractor. It should have a primer lever on it. Follow the fuel line from your fuel tank to the lift pump.
From the lift pump you will have another line that goes from there to the fuel filters. You may have one or two fuel filters.
On the top where the lines connect, it should have arrows showing the fuel flow direction. The first filter should have only two lines one in from lift pump and one to the secondary filter. The secondary filter should have three lines going to it. The one from the first filter, and two more on the other side. One is a return from the injection pump and the other is the line going to the injection pump. Open this line just far enough that diesel can leak out there. Hopefully you have the arrows?
Once you have this line open...pump the primer lever on the lift pump until fuel runs freely out this line. (If you find that the primer lever is not making a full pump...[the pump may be on a pump stroke right now] you may have to turn your engine over until it will make a full pump.) Then close the line tight.
Next you will find on the side of your injection pump (The pump with all the lines going from it to the injectors) A small bleed screw with two hex heads, should be a 3/8 wrench or 5/16. Open the top hex head just a couple of turns (Not the bottom one). Go back to your lift pump and continue pumping until you have a good stream of fuel coming out the bleed screw. Close the bleed screw.
Next open all your injector fuel lines a couple of turns until you can pull the lines back and forth in the line caps (You don't need to take them all the way off).
Next use your key to turn the engine over a few turns until you have fuel leaking out the injector lines at the injector where they are loose. You may have to tighten the lines as they get fuel leaking out each one. Once all the lines are leaking and then tightened again. Try to start the engine. It may run rough until you get all the air out, but it should level out soon.
If you don't get a start relatively soon you may have to repeat the process until you get all the air out.
These instructions are for a Massey super 90...but I believe all perkins engines from this era have the same bleeding process.
Hope this helps,

These are from a Massey 168 handbook but The 168 and The 175 used the same Perkins 4/236 engine so the principles are the same. When you are replacing filters take care not to over tighten the bolt that holds the glass sediment bowl, otherwise you may wake up one morning to find a big pool of diesel on the floor mixed with broken glass.
Hope this helps.

You possibly have a clog in the fuel system somewhere. Spiders and webs in the fuel tank (they get in the nozzles of the on farm fuel tanks) are, in my experience, common. You could have a clog in the bottom of the tank, the check valves in the lift pump could be held open, or some other line or fitting could be clogged with spiders or other junk.

First, get a flashlight and take a good look into your fuel tank.

I can tell you from experience, even if it shows there is over 1/4 tank of fuel if your on a hill for very long the engine will die from no fuel. I did it once on my 175 mowing hay. I'm in the hills here in East TN and I see from your name your in WV where there is plenty of hills. Unless I'm on flat ground which is rare I try to keep 1/2 a tank of more of fuel in it.
 
Problem solved! Just needed to bleed
aitlr out of the injector. Runs like a
champ. Now just need to keep it full!
Thanks for all the help guys
