Hello all

I know nothing about engines. Am looking for help.

My B7100HST was overheating so I changed the oil, blew debris out from the radiator grille, and topped up the coolant. Tried to start it and it sounded like it was going to start, then lost all power and just coughed instead.

Opened the hood and a hose has come loose - both at top and bottom. Pic 1 shows the top of the hose, pic 2 shows me holding the bottom of the hose, which looks like it has torn off something.

Questions:
1. Is the hose broken and does it need replacing?
2. How do I reattach the top of the hose?
3. To what does the bottom of the hose attach and how do I attach it?

Thanks very much in advance for anyone who can help...

It's just a breather hose. Replace it, it's hard and brittle. Vinyl tubing at Lowes, cost you about $2.


Has nothing to do with it starting or not.

That's the crankcase breather hose, just slips on the downward facing hose barb in your first pic, the other end is just open to atmosphere, not attached to anything. Should have nothing to do with you starting problem, maybe someone else has an idea about that.

A breather hose! Thanks. I've roughly reattached it at the top. Is there a trick to getting it back on? Soften it up with heat? Does it need a clamp to keep it on?

Re starting the engine: when I turn the ignition key to the left to warm up the glow plugs, I'm not hearing the clicking noise that I used to hear. Could it be a glow plug problem?

When I turn the key to the right, I get a half-hearted groan from the engine. I see the fan behind the radiator do a quarter turn, then nothing.

Time for a new battery.

Check your connections and cables first.

Take battery to dealer or auto parts store. They can test it. If it's older than 5 years it's probably time for a new one.

Probably need a new battery. As part of the replacement process be certain to clean the chassis ground connection---remove all corrosion, rust, grease, gunk, make bright shiny on both chassis and cable end and bolt and washer. Reinstall using conductive thread sealant like KoprKote or electricians NoKorode (as used with aluminum wiring).

On new battery make a thick (like peanut butter) paste of baking soda and water and make a mound around each battery terminal. Let dry to hard crust. Replace every couple years by washing clean with water. Simple cheap easy works.

Northern Rivers Blade,
The clicking you hear when you turn the key to Glow Plug is the hour meter clicking.;)

Use an old screw driver and go on the back of the starters solenoid and use the screw driver to short the small bolt to the top large bolt.

The solenoid should engage and the starter should turn.
If it does then you have a wiring problem.
If it doesn't you either need a new starter, or more serious the engine is locked up because of a problem, be it fuel or water in the cylinder or a mechanical problem.

I'm sure Wolfman just forgot to mention this. Just a word of caution. If you're doing this with the starter in place, make sure the tractor is in NEUTRAL to avoid the chance of it starting and running away on you. Or over you.

Hello all
Have had the battery tested and it is OK.
A mate has suggested giving the solenoid and starter a tap with a jimmy or a hammer. Where are they? Can this help? Any other ideas?

He is asking where the starter and solenoid is.



OP,

You need a manual. You also need a friend or someone with knowledge to go over the entire tractor with you and teach you the basics.
Until you get the basics.............I would not do anything to your tractor.

DEFINATELY DO NOT cross the starter until you are positive the tractor is in neutral and the brakes set. Years ago, a farmer near me who had farmed his whole life, made the mistake of not putting it in neutral, and the tractor drove over him. He lingered for a few days in the hospital before dying.

Oops... My bad!:eek:
Yes always set the brakes and make double sure it in neutral!!!!
Blocking the tires would also help just in case, but with these little 4x4's they will climb right over a little block so use a large block! And block both the front and back of the tractor just in case it's in reverse.;)

An operators manual would help you out tremendously and so would a service and parts manual. If you don't have any of those, shoot me a PM with an email and I'll send you a copy them.

Thanks everyone. I've had some help from a friend. Doesn't look like it's electrical at all. Oil level was very high (even though I had put the right amount in) so we drained oil again and it had some coolant in it. Now have coolant coming out of exhaust when I try to start the engine. Calling a mechanic.

Water or coolant in the cylinder is called being "hydro locked".
It either has a blown head gasket, or worse yet cracked head or block.
