300+ rebuild

[Geoff Weeks]

I installed my liner seals with rubber lube, that way they didn't start to swell until hit with engine oil. Cummins says to use vegetable oil for lube, which is also the base of rubber lube.

-71 series were dry, -92 series were wet, when it comes to 2 stroke Detroit.

Interesting GW.  The 3179 DF john deere engines I built says use Dawn and water mixed, and be quick because the oring will swell. Those liners had 3 different types of orings, so position was key.

Question of the night:

Pulling injectors.  Mine are "stuck".  Tried giving one a smack with a pry bar and no go.  

Puller the best way?  Do you remove the nut and thread puller on that(what thread is it?)or use the banjo threads(which seems like metric m10).

[Joey Mack]

Shouldnt be metric.  Do they turn a bit? The oring is probaly rusted and stuck. My 673 took hours the get them out. I used penatrating oil and a long big screw driver to work them back and forth and every so often i would pry them up and rotate the best i could.  I also had to work the studs out at the same time.  It sucked because i didnt ever do it before.  The heads were from an engine that sat outside, uncovered..
