Massey 6485 injection pump modification

[davedb]

Bit of a project on my 6485 to remove electrical controlled bosh injection pump and ecu and convert it to a stenadyne manual pump which has been set up to give about 200 engine hp

Had to make an adapter to reduce the hole in the timing case to suit the new pump

fuel filters had to be moved with a new bracket which also holds the throttle cable

runs great now just needs the dash reprogramming to think it’s a 6465 with manual injection so it doesn’t throw up errors searching for the engine ecu

Why did you do this?

 

[Old apprentice]

Have you done this entirely your self or some other input ok.

 

[davedb]

Why did you do this?

The bosh pumps arnt the best and this had gone bad starting when cold so this pump solved that problem and also gave a boost in power

Have heard the pumps give bother but have never heard of anyone going to this effort. Well done, top job

This wanted to be well known proberly help a lot of people.

Did the throttle take much rigging up

No all fergys have the rod from the foot throttle pedal and bracket on the cab ready all you need to do is remove the spring and replace it with a cable I got this one of a 8130

Great work.

I allways wanted to give it a go not heard of it being done before but couldn’t think why it wouldn’t work

 

[bill and bens dad]

Great job, those stanadyne pumps are great for low down torque, Mf 6180 tractors had those type pump we had ours tweaked which gave it much more torque, greater by far than the Mf 6290 which in my view a better tractor bar the crap Lucas Delpi pump, wish i had been brave enough to do what you have done, Will you dyno test her?

 

[davedb]

I’ve got a 8130 with the same pump that’s why I was keen to try it really does give them some low down grunt yea hopefully dyno it at some point

 

[davedb]

The other benefit is she now does 50kph as there’s no rev limit on top gear now

 

[Farma Parma]

Go on Dave thats impressive if you get it all working correctly. Them Stanadyne Pumps rarely gave much trouble right enuff

 

[Farmer_Joe]

thats ace,

can you take a pic of you old pump drive shaft?

i want to see if its the same as my 6465 (mines same pump as your first pic or very similar) , sadly its a harder job on mine as the bloody water pump is right on the face of the pump other side of timing cover.

Did you swap injectors aswell?

where you get plate from for the pump to mate to timing cover. whats the donor pump off?

Yea I’ll take a picture hasn’t your 6465 got a manual pump on already? We made the conversion plate

no its vp44 like yours, i found to my expense when it died 2 years ago, i got new one but i always think it would be better with older style pump.

You keep same injectors or swap them? had nijne done with pump but to be fair they seem fairly std so imagine they would be fine with a old style rotary pump.

What engine has you mf got looks slighly different layout to mine i assume its perkins 1006?

 

[davedb]

I’ve got new injectors but not swapped them yet, this is a sisu 6.6

 

[bill and bens dad]

from memory sisu injectors are cheaper than the Delphi Perkins ones? Did you have to change the injector pipes?

 

[Farmer_Joe]

I will get pic of my old pump today, looks like he’s had to swap injector lines I wonder if I could get pump off 1006 say 6200 series there manual pumps
