6.5 turbo injector rebuild
 

Hi i have a 94 6.5 turbo. the injectors are still good but ive been looking for a rebuild kit for the injectors. if its cheap enough ill rebuild them as preventative maintenence.anyone know a good place to get the kit or parts to do them? thanks.

Local Stanadyne dealer,ebay sometimes has bosch standard duty nozzles for a good price,rock auto?

Bosch,Delphi,Stanadyne nozzles only and standard duty ONLY.

I was looking at some through rock auto the nozzles for about 16 bucks a pop. id have to buy new seals as well? there any special process to it or just swap the nozzles n seal n torque em down? thanks

they should be calibrated to pop off at a prescribed pressure-2150-2300 psi and have all 8 within 5% of each other.

an injector pop tester should be used and a selection of shims is needed to calibrate each injector.

video of me testing rebuilt aftermarket 6.5 TD injectors-note that they poped at the naturally aspirated pressure instead of the turbo spec-they need to be shimmed to get the proper setting.

If you don't test them you could end up with dribbling injectors or improper pressures that can melt pistons or give other problems down the road.

Most farm equipment dealers or your local diesel shop can rebuild the injectors much cheaper than you buying the equipment yourself for a 1 time use.

here is an example of a DIY pop tester:

An injector install kit is the way to go to get the copper washers and new return lines,lots of kits on ebay.

Also don't get sucked into the marine nozzle/injector hype-there is no improved power potential wit them unless paired with the mechanical marine IP,the IP is the bottleneck in the fuel system-standard duty injectors can flow more fuel than the IP can provide.

Thanks. i knew abouth the extra horsepower injector scam. ill prolly just wait to replace them when they go bad and just buy new ones at rockauto as the only farm equipment place close is john deere and they arent cheap on anything haha thanks

Injectors should be changed every 100,000miles

all great info above by the way
