2010 Backhoe fuel and bleeding problems

Post by Scott G » Wed Feb 15, 2012 4:53 pm

I have a 1968 2010 Backhoe Loader. I have just put on a rebuilt Roosa Master fuel pump hoping it would solve the stuborn starting problems. Does anyone know how to bleed the lines back to the fuel injectors. It still doesn't seem to be getting fuel. Thanks for any help.

do you have fuel to the pump? if you do then take all the lines at the injectors lose and crank with throttle at about half watch till you see fuel tighten and it should start ...ps i think the last 2010 was 66

Thanks I will give it a try this morning and keep you posted. This machine has always been hard to start, but once it is running it runs great any suggestions? Thanks again

do you have a primer pump? and are you using the preheaters/glow plugs? have you checked all of the glow plugs to see if they are working? DO NOT USE STARTING FLUID

I was able to get it bled doing just what you suggested. and got it running it sounds a little rough. I may need to adjust the timing at the pump. Why should I not use starting fluid, or ether? When I bought the machine 15 yrs ago. I was told to use a shot of fluid when it was cold out. Is that wrong? I have glow plugs, but they just dont seem to do the trick. Thanks for all of your help.

have you checked the glow plugs with ohm meter? or amp draw? all four have to be working to start well and after starting you can glow some to smooth her out as for it running rough now it will still have air in it run it for awhile and it should smooth out ...(ether) 1010 2010 are indriect inj. engines and you can break things like precups......rings

Man You are a wealth of information! Do you know what the Ohm's of resistance should be? The glow plugs are farely new and feel warm on top after the have been on for a couple of minutes. Maybe I should leave them on for longer before attempting to start the motor. They seem to use alot of the battery power. Thanks so much

amp draw should be 7 to 11 amp each that is best way to check .... you can also just pull each wire and touch each to glow plug with 12 volts and see if you get any arc ....with ohm meter just see if they are not open

what trans do you have in the 2010 HLR (powershift) or a constant mesh trans? also, do you have a primer pump?

No there is no primer pump, and the trans. I'm not sure. It has a shift from forward to reverse on the left that does not need to be clutched but the gear's 1-4 you need to start forward motion in the desired speed. The engine seems to be running preety good now except for some steam or exhaust coming from a pipe right at the nose of the starter. Any ideas on that one. Thanks so much for all of your time and help.

if you can shift the floor lever (HLR) without the clutch then you have a power shift/HLR when you are starting are you disconecting the trans? (rod on left foot rest)?and are you preheating for at least 30 seconds? as for the steam/smoke that tube is the crankcase vent tube more blowby = more smoke there.... what size battery do you have and 1 or 2? how fast does it crank? if you are in real cold country you should put a primer pump on..... mine start so nice all have preheaters and primer pump

Hi Scott-

Welcome to the board-

There are a lot of great discussion threads in the archives of this board about 2010s that go into a lot of detail on the questions you are asking. Specifically I know there is a great one about testing glow plugs and others have posted a few about bleeding. You may want to do some keyword and author searches to read about these topics in more depth. JTrichard and myself have been in quite a few of the more recent discussions so you can start with us for the author searches.

I know how it is- several years back I was in the same position and you will have a lot of questions. There are some great people on this board that will answer any question you have, but the archives are really handy :D

These posts have been a great help. My Machine seems to be running pretty good now. I would really like to know where to get a primer pump as was described by JT. Thanks for all of your help. I know I will be back when it's time to address my blowby issues. Thanks

Hi Scott-

We have a detailed thread in the archives here about both the original primer pump and aftermarket solutions for it. If you do a keyword search for "primer" and an author search for either "tigerhaze" or "jdemaris", you will find it. I'll look for it if I get time.

EDIT: I had a few spare minutes so found it; here it is:
