Hello, We pulled the injector pump off and placed the rebuild on but it won't start. Only smokes a little white. Bled injectors and have fuel pumping to them but acts like it is 180 off. We have the engine mark and pin pushed in. Can u help please
But is the #1 cyl on TDC with both valves closed? The pin will go in on the exhaust TDC as well, so it is possible to be 180 out at the injector pump. Pop the #1 cyl valve cover off, if either or both valves are partly open or have no lash, rotate the engine in the normal direction of rotation until the intake valve opens, then closes, then continue a bit until the pin pops in. That should be TDC compression #1 There should be a little window plate on the side of the injection pump, once you are sure you're at TDC compression #1 you can pop that little window off, there will be fuel come out, and check that the two timing lines line up there. Good luck!
Yup.. 180* out.. either the pump or the engine.. Did you notice the dot on the end of the drive shaft? theres 1 inside the pump too.. match the dot to the dot and your good to go. then fine tune with the pin and timing lines inside the pump. AND don't roll the seals on the drive shaft..
Thank you. I have tried to rotate 180 and check that the #1 is tdc, but am not sure of the window on the pump. I removed the plate on the side to look but it is only to the injector pistons and springs. This is a 1999 model.
Did you remove the nut on the shaft when removing, and was the pump tang bolt and lock in place? When the new rebuilt pump came back was the tang and bolt locked and did it line up with the key in the shaft and the drive gear to slip it in or did you loosen the lock tang and have to turn the pump shaft to line it up with the key way in the gear?
It does not have a key in it. It came timed and I am not sure what my guy did in the beginning placement, I was not there. But the way I understand it the pump is pre timed you just have to place the engine on tdc #1 and install. He clames to have initially done this, I have since retried to do it but am not sure where the pump is supposed to be to be correct on timing.
Welcome to HEF jpainter! You would have an inline pump on that engine. I"ve described the timing of that pump here - HeavyEquipmentForums That thread is regarding a skid steer - but the engine timing detail is correct info for you. :drinkup
Well huh, who'da thunk?
I was thinking it was a Roosa Master/Stanadyne pump.. Need some engine and pump info.. #'s off name plate. Sorry..
That's what the parts book shows, rotary. Go figure.
Thank you guy's! I will try this today or tomorro. Again Thank you
That's the reason I was asking, the L series had a rotary pump and the series 11 had the inline I thought. So many machines out there and this is the reason to post the s/n and series if you have it. Some machine in the US will also have different engines and power trains than the same series out side of the US.
JPainter>> this is in NO WAY directed at YOU.. BUT it does fit.. FOLKS>> PLEASE help US HELP YOU.. There is a # plate on the injection pump AND a # plate on the engine.. some where.. if you JUST HAD your pump done.. look on the invoice.. its on there.. Sorry.. had a bad day..
Of the three different pumps fitted to the L series - the only one that does not have a woodruff key at the timing gear is the bosch inline pump. Also if jpainter removed the side window & "saw pistons (plungers) & springs" ......... That's the problem with doing repairs over the internet, you can't see the problem & you can't assume. Shows the importance of the advice giver to ask questions & the advice receiver to answer them. @pumpguy - you know the pumps but I know the machines.... (Case) :drinkup
You sure do know your engines!!! It makes my head spin how fast you answer some of these problems..:notworthy The internet has been a life saver for ALOT of folks, including me.. My latest "go-to tool" has been the picture phone.. I get about 20 phone calls aday from folks TRYING to fix a leak or work on their pumps.. Call goes like this.. Hi, I've got a diesel and got fuel coming from the little gizmo by the thingamajiggie.. do you have the oring that goes in there?? Me.. do you have any #'s off the engine or the pump?? Caller.. NO.. Me.. can you snap a picture with your phone and send it to me?? Caller.. Heck yeah, no problem.. saves me about 30 minutes a call..
