Ford CL55 Bleeding air from fuel system?
Posted: 04/15/2012 10:09 AM
Just got this 85 Ford CL55 a week ago and cannot figure out how to bleed the air out of the fuel system. It has fuel to the pump but after that it is just barely dripping and the machine will not start. There is no solenoid on this setup so it is all gear driven. I see the hand primer but no clue where to bleed the air off. Thanks in advance!

Are you talking lift pump or injector pump?

If the fuel isn't getting pas the lift pump, it may be bad. If its not coming out of the injector pump your fuel shut off solenoid (if fitted) may be stuck or bad.

As in my original post, there is NO solenoid. I am getting fuel TO the primer pump but not to the injectors. How can I bleed this setup? Does it need bled at both the lift pump and injector pump? If so how? I don't know much about these.

While your motor may not have a solenoid, there has to be some form of shut down mechanism that shut's the fuel injector pump output off.  A lever or something.  I have fought with many an old motor only to find out I didn't even have the fuel turned on. 

Now, if your absolutely sure that your fuel is turned on, I find using a marine style primer bulb helps greatly.  You put it in the fuel line before the primary filter.  It only costs like four bucks and I install one on every piece of equipment I own and every piece in our fleet.  If you change the fuel filter, squeeze the bulb as you tighten the filter and it fills the whole system up so no hard starts.  Also is a huge time saver if the guys run stuff out of fuel.  Using that method, you can just have someone pump the bulb while someone else cranks and most of the time things start in short order.  If you are alone, just crack the lines on the top of the injector pump till fuel flows out then tighten while its pumping (so air doesn't go back in). 

Growing up I was told horor tales of airlocked motors taking mechanics all day to get running.  I have not seen such a thing and I have seen a lot of motors.  If you do the steps above and it still won't pump, its something else.

Thanks Mike67, I will try that! I think there is a lever that shuts it off, and I wonder if thats worn and causing the problem. I'll have t check that out! I did try turnng it over with the lines cracked at the injectors however doing it alone doesn't work that way. I just get a few drips out of it. Cant put the bulb in before the filter on this machine but I can get one after the filter. Before the filter there is a very short metal line from the tank. After the filter it is all rubber lines. The filter has a bolt on top to bleed it. I am wondering if I could bleed the pump from the two end bolts on the top. A picture of it here http://www.ebay.com/itm/NOS-Ford-Skidloader-Fuel-Injection-Pump-CL45-CL55-CL65-/280558729743 and they are the two above the hand primer and appear gold in the photo. They have nuts with a screw in them. Not sure if I can bleed it from there or not! In the exploded parts view it doesn't appear to be an adjustment screw but I could be wrong too. RJS

I went out just now and pulled those two bolts and both had air bubbles in them! I also found what the lever is up front....fuel shutoffSmiley Now to hook up the battery charger again. II did notice that there is a spring missing for the throttle return too. I'm sure I have something here for that. Anyway, getting that air out of the pump should help matters in that area.

Still no goSadIt is trying to start but just doesn't seem to get enough fuel. Tried WD40 it tries harder,in fact it will actually run if you keep spraying it. Twice I had it going two or three seconds. I am starting to think the injector pump is bad but yet it does pump fuel enough that I could bleed it. Any suggestions on what to try next?

I wonder if its still bleeding through.... If its spluttering it means its getting some fuel through, i wonder if it could even be an injector issue? Just seems strange its not priming as it should.

I assume you never had it running, so i wouldn't ruel out an injector issue either. If you crack the high pressure lines, crank it, does fuel well up around the fittings? If so, it sounds like you are getting fuel.

If injectors are not used for some time they can stick. Some are easy to pull down and clean and re-assemble. I have done it a few times with great success. Clean with compresed air and WD40, re-assemble with the same WD40 and they will hopefully be good to go.

Nope, I haven't run it, I bought it minus radiator and battery which were stolen after the owner passed away. It sat in a barn for two years after he died so you coukd be right about the injectors. They do appear easy to take apart looking at the parts diagrams. And yes, I did drain the fuel out that was in it. Put the same amount back in of new fuel. It's trying to run, it puffs out some smoke when trying to start just won't run. Can't complain much for what I paid though. Well, guess thata tonights project, try and get those injectors out. Tried once and they are tight! RJS

Gotem out..... breakerbars are great! Anyway here is what I saw as I pulled them. 1: completely dry 2: soaked 3: soaked 4: bottom dry, sides wet I will assume the two that were soaked are 1&4 are stuck. 2 bled easily, the others work a job. I spent 3 hours doing that yesterday! RJS

what I meant to say was the two that are soaked were ok but the other two stuck or partiallyblocked. I will pull all 4 aart though and clean them. Not too bad to get them apartSmiley RJS

Good plan, pulling them all and cleaning them. The wet ones may be stuck open too.

The smoke you have been getting will be the fuel not burning, hopefully the injectors is all that is wrong *crosses fingers*

When you have them apart, keep them seperate, don't mix parts. Ensure the plunger in the nozzle is free to move. I have had some that were really stuck. I needed to hold the base in the vice and lever the nozzle part up with screwdrivers. When it was free, they cleaned up really easy and were free to move.

While the injectors were out if it were me, I would take some marvel mystery oil and pour it right down to the cylinders and let it sit overnight.  Not a lot, don't wanna hydro lock things, but since the motor has been sitting idle for a while you want to make sure all the rings are nice and slimy.  This will ensure that, A, you have good compresssion, and B, that things are properly lubricated from having set for a prolonged period of time. 

Also, if the WD doesn't loosen things enough, try AeroKroil.  WD isn't really a hardcore penetrant, but Kroil is.  Orange colored spray can.  You won't find it in the auto stores because its not a “value“ brand and will probably have to get from an industrial supply place, but very worth it.

one the nozzel is stuck, it is sitting in and has PB Blaster in it. we'll see if that loosens it up overnight. the few seconds it would it sounded good so hopefully it will be OK. If not it will sit a while as i don't have the $$ for a motor right now and parts are not cheap for this motor. And finding them is tough too. Thanks for all the help so far! RJS

well that didn't work. Got the needle out finally but after reinstalling the injectors it still won't run. Judt sits there with puffs of smoke on occasion. WD40 dosn't help. Not sure what else to do and no one seems to have any running motors to drop in it and I don't have $3600 to drop on a new motor and so forth. Guess it will be sitting a while and my driveway will be filled with these logs a bit longer...... RJS

Get your paws on a diesel compression tester. Ensure the fuel is off when testing, you don't want it to fire.

Install it in an injector hole or glow plug hole. You should get around 400 PSI, it will still work if its lower, just harder to start. 300, i have been told is the bottom of the scale, it will be very hard to get going at this compression value.

Get those readings, and you will have a better idea of what needs to be done next.

well tonight I found two running engines..... now which is going to be easier to install and better to run in the cold? I have heard good things about Yangmar and cold starts, thats a 44hp 4 cyl and they also have a Kubota 46hp for the same price. A guy who knows diesels better than I do said at a minimum my motor needs rings but it really needs a whole rebuild due to moisture that sat in it while parked. So it would cost $1000or more to do it right on a rebuild or get a motor that parts are more readily available for. Personally I think the better choice is the latter, just not sure which engine to go with. I will need it to run in the cold though. RJS

lol, found the problem Tazza! no compression! Didn't need a tester either. Went to loosen the plate bolts that attach to the back of the motor and even with a 1/2" wrench the motor turns. It shouldn't turn that easy. Sooooo..... a motor swap is deffinately in the works. RJS

Well, if you believe you can mount it up, i'd go with the Kubota. Parts are easily available. If you go for the newer ones, like a V2203 they start quite easily, not sure how they go without a heater in below freezing climates. I'm from Australia, my V2203 powered machines fire right up, even when its really cold.

You can buy heaters that install into the head and warm the engine up to assist in cold starts.

The older Kubota engines don't start quite as easily, but they get there with a bit of a glow.

According to the guy with the motors they should mount up fairly easily. Wider oil pans but they have plenty of room. May have to drill a few holes here and there but otherwise should work. As I hear it either should have parts available. The Yanmars being used in John Deere equipment helps as there is a JD dealer nearby but then there are a couple of others that carry Kubota stuff nearby too so I am good parts wise with either choice. The question I have is will I need to do anything different going from 42hp to 44 or 46? The Kubota is 46 and Yanmar 44. I'll probrly go with a choke cable setup with the Kubota for the fuel shutoff, the Yanmar has a solenoid. I may need to set up a relay and switch for that. The only other change will be the throttle linkage but it shouldn't be much different. Fortunately we dont have too many bad winters in Indiana but we do get days or a week at a time it's pretty cold. However the machine will be in a heated shop except if I need it to clear my driveway or move wood for the splitter or bring wood into the shop. I usually have 2 to 3 week supply of wood in the shop though. Can't wait to get this thing running and put it to work here! RJS

I can't see an issue going up a few more HP.

The fuel shut off solenoids are easy to setup. Some Kubotas have them fitted. If it has three wires, you have ground,  pull and hold. Wire the pull to the starter, so when you crank it pulls the plunger back. Wire the hold coil to the switched power in the key switch. When you turn the power off it will shut down.

The older bobcats with kubota engines used the same choke cable setup as you describe to shut down.

oppsss.... missed that first line Tazza....that answers the question. Looks like I am going with the Yanmar, it's newer than the Kubotas he has and has direct injection. I will need it in the winter so it will help to have an easier starting machine then. Also the Kubotas have a larger bellhousing and I am not sure they will clear the crossmember above it. Also the the flywheel is 14" on the Kubota, the Yanmar is 12" and my coupler is 11 1/8th. Either way I will have to make my coupler larger and drill it for the bolt pattern and pins on the yanmar. I will wire up the solenoid on the Yanmar and my present wire to the glow plugs will go to the heater on the manifold. One nice thing is there will only be 2 fuel lines instead of 3 after all this too. I got the Shibaura engine out today. Easy enough to do. Now if this other goes in as easy I will be happy! I just need to fabricate a new radiator mount and will probably use some 1" square tube and angle I have sitting around here for that. I am in for a fun project here!

Hopefully it will all go easily. As long as pictures are taken. Always interesting seeing how a new engine goes in, hopefully it will work better than ever.

Ok, lets try here! Been trying to post in the repower section and it is not working. Hopefully Geoffrey can figure out why. Anyway the studs are large and there are 8 of them on the Yanmar engine. They are pressed into the flywheel. Can't post a photo as there is no way to upload it here. RJS
