 Topic: 190xt dying
Posted: 24 Feb 2016 at 5:36pm |
|
Ive got a 1969 190xt. It takes a couple minutes of cranking to get it atarted, everytime you start it. Now it will run for a bit, then just suddenly die. Sometimes it will only run for a few minutes, other times a half hour or so. It stutters for about 2 seconds then off. Seems to me to be losing prime in the fuel system. Ive tightened every fitting on it. Bte it also has an aftermarket electric fuel pump right before the fuel filter. Thank you in advance.

check the electric pump and make sure your getting a full stream of fuel might have some thing in the tank that is sucking over the settling bowls and could be a bad pump even if it sounds like its pumping and make sure your return lines to the tank and the pump are clean NIEL

That electric fuel pump trick was prolly a farmer cure for what's really wrong with it, lift pump, in the injector pump, is losing the carbon vanes, and clogging the works up, would be my guess...

Carbon blades? Not on any 190's.

Check your fuel source from tank, Ive had a 190 clog up at both sediment bowls on each side of tank and cause it to do similar thing.

a lot of times, if the electric pump isn't run for awhile, they dry out inside and won't pump up pressure, have had that several times!

Loosen timing window to where fuel leaks out then try it. If it runs ok then, weight retainer has come apart, pluging return fitting. MACK

The electric pump spits fuel, it is quite a bit of fuel but not a steady stream.

usually when they get junk in the tank, it comes from the pump flex ring coming apart in the first place. That's why I don't like knocking the return ball out and considering it repaired lol!

My 190 does the same thing,--- but I think it might be two things causing the problem,--- 1 is crap in the fuel tank and 2 the governor surges BAD unless you pull the tractor HARD, then it runs smooth,--- ( until tank clogs!---might be 5 mins. or an hour!)---cant get the tank off to clean it without getting rid of the cab and fenders, from what I can find out.
Its a good tractor, but not a trustworthy one!
As far as primer pump, Khuns ( ac dealer) wanted $ 185. for a new one, so I went down the street 2 blocks to napa and got an electric pump for $ 50. and put it in place of the hand primer pump that was leaking BAD.---fuel is supplied to transfer pump under pressure and it runs good until tank plugs again.
May not be acceptable fix to CORRECT POLICE, but its MY tractor and I have to do the lesser cost of fix to get things going! thanks; ac fleet

This may be a dumb question, but should the valve on the sediment bowl be screwed in or out to run?

Make sure you clean both sediment bowls while your at it. The first couple times mine quit I cleaned the right side bowl but didn't know about the left one.

Are you trying to run it on BIO CRAP for fuel?---If so you have probably messed up the injection pump, I have 4 tractors that has had this happen for me ---loosen the fuel lines and see if fuel is even getting to the injectors.---could even be the injectors gummed up from the use of BIO CRAP.---these old tractors were made to run on REAL diesel fuel. thanks; ac fleet

Loosen the actual injector itself? It will idle forever and not die. But when you're driving it will randomly die, then take a couple minutes of cranking to get it back started.

NOT the injector itself, but the line from the injection pump to the injector. you will reach a point that it will die and NOT re-start.---at least mine did! thanks; ac fleet

the return line is plugged up with broken flex ring material, it will look like coffee grounds. Leave the timing window loose on the side of pump, and see if it continues to run without losing power and dying off. Put a bucket under it. This is a very common issue.

The pump has to come off and sent to a pump station. They will clean out by replacing what is plugged and replace what is coming apart in pump. MACK

Yep, time to get the pump rebuilt. Very common with Roosa Masters.

Does this pump have a certain way it has to be taken off? Like a timing mark or anything?

YES!!! Take timing window off pump and turn engine till two lines match up.At that point the balancers timing mark should be in line with the pointer.Don't know the # degrees for your engine but Ed will know. FYI The pointer on my 220(426) is kinda lame.Your 301 may be the same.If your outer ring has slipped it won't show what it should.

A 190XT timing will vary by pump model number, but most are either 24* or 26*. Line the marks in the pump up(small rectangular cover next to name tag with 2 slotted screws holding it). One of the marks will be there already, the front piece will rotate with the engine, and turn the engine until that mark lines up with the stationary mark. Your pump rebuilder will be able to give you the timing spec for your particular pump. You can also scribe a line on the pump mounting flange, and engine.

The pump is a bear to take off and a double bear to put back on and get to work, (timed correctly) ,so I would strongly suggest that you send the tractor down the road before it blows up completely and you end up with selling a non-runner, (junk price) tractor! thanks; ac fleet
