Recently replaced the fuel pump on my 07 Branson 3510i and now I can not get above 1200 rpm

Did you change the fuel filters?.....

Recently replaced the fuel pump on my 07 Branson 3510i and now I can not get above 1200 rpm

was this the fuel lift pump, or the fuel injection pump, without knowing which one it will be hard to pinpoint hat you may need to look at.

I'm not sure a friend did the work but I'll ask

How much did it cost might give us an idea. A couple hundred should pay for the car like fuel pump on the firewall. I replaced two of these at $17 each. The injection pump (IP) might run you $2k or more.

 

[sawdustmaker]

Based on that ...it wasn't the injector pump. Ouch

 

[sawdustmaker]

Sorry for the delay in checking back in (dealing with the big C is no cake walk. My son is the one that got the fuel pump installed and after telling him what was going on he said it was NOT the injector pump. He had the feller/friend he hired and got it worked out.
Thanks for the help.

Taking Robert Bosch ve fuel injection pump off problem can’t get it off gear goes about 1/3 then won’t go, does it take special tool to remove pump? Thank you

Mine is 2910i Branson with Kukje engine , thought this might help, I’m going to send pump and injectors to company in Dallas area to be rebuilt , pretty sure this is cause of tractor acting out of gas, we know for sure pump is weak because no fuel to number 3 and 1 injectors , after bleeding air, and trailing all fuel items. Thank you.

Look at the face of the gear..
Does it have 2 threaded holes in it.??
If yes, it takes a puller to pop off the gear..
BE SURE TO TIME IT OR MARK THE GEARS TO EACH OTHER WITH A SHARPIE before removing.

Brother had taken off view plate 4 bolts with copper washers, looked inside with camera probe he saw , he thinks 3 threaded holes, would like to know thread size? I took pictures with my phone, not very good, but I see 1 and felt 3. Brother has marked TDC and gears. Will email this to you, but thought I would share with forum. Thank you so much, Sally

How about taking a pic of the pump so we know wth we’re working on..

 

[sallyb]

Sorry didn’t think of that lol. Will do.

That looks like the opening to the IP gear. The yellow painted lines are matched up and I would presume would indicate the pump is properly timed with the engine. Im not sure about your white mark.

 

[sallyb]

These. Are pictures I took of pump . So yes it has 3 threaded holes to use puller can someone tell me where to find what size these threads are so a puller can be used.

 

[sallyb]

The white is used to mark cables . This . As you see pump is still on
tractor. Would we need to take off radiator and the item with Item with view plate? I guess what I need is how to remove pump. Thank you

On second view, the white paint looks like your factory timing mark. There appears to be a mark or groove under the paint.
I would turn the engine further to see if there is a mate to this mark, if so, use the white mark. Did you add the yellow paint?
Have you tried to remove the nut that holds the IP gear? A photo you posted shows that nut still on the IP shaft, but the gear is set back-so the IP mount must be loose.
You may be able to slide the IP out and the gear off just by removing that shaft nut.

 

[Zork]

You need to get a few metric bolt sizes and threads to find out what pitch those holes are. Hopefully that gear comes off easily once you remove the mounting nut. If nothing else, get some coat hangers or rods in those holes so the gear doesn't drop down where you might not reach it. And watch for the IP shaft key, you won't want to loose that.

 

[Zork]

There appears to be two threaded holes on that gear. A general metric sized puller set or steering wheel puller from HF/Advance/AutoZone should include those bolt sizes and if the gear is loose, you might not have to remove the shroud/radiator as the puller body without the center stud will just hold and align the gear while the IP is out.
