3505 Massey question

Can the injector pump be adjusted to give this tractor maybe 20-30 more hp safely or are they normally close to the safe limit as is and trying to turn out more is just looking for trouble? We have a 14? Kongskilde 2800 5 bar field cultivator I?d like to pull with it if possible. As it is now it will barely pull them along in good going.
 
NOT without a turbo, and the injection pump may have small plungers limiting how much increase it has anyway. Need to know the pump number to see what hydraulic head it has. Probably five HP increase max without a turbo, if that. More fuel will just make more smoke and heat only.
 
I would also worry about the transmissions and rear ends on that series too. They have a terrible reputation around here for transmission/rear end issues. Very low resale. So must be more than rumors.
 
Thank you Dieseltech,I?m pretty sure it?s a Lucas CAV but I?ll get the number off of it. It throws quite a bit of coal smoke already so it?s likejy getting all the fuel it can utilize now.
 
We?ve had this one close to 25 years and have been very lucky. Our neighbors had several of the series before ,2775 and 2745 and they were complete lemon?s in the powertrain department. Either they solved the issues with the 3000 series and by then their reputation was already damaged or we just got lucky.
 

"quite a bit of coal smoke already" is a good indication that it is already getting all the fuel that it can usefully burn.
 
The 2XXX problems were more in materials and execution than design. Co-worker who had been a tech with/for Massey at the time says that by the time 2XXX series was done production they'd pretty much got everything figured out. Sounds like they needed 2-3 more years of testing before releasing them. There are some videos out there where the guy goes through all the updates.
