300+ rebuild

Or a straight round drift or a screwdriver to put into the washer hole but deep for washer thickness only. Than try to work as a lever, possibly hitting the tool by hammer at its side.

I dont know that the seal will ride where the little dings are.  What say you,  mech ?

it will be a close call; keeping in mind the replacement hub is going to be shorten!! placing the seal closer to the marks 

[Joey Mack]

Yep.. i see that now.  He did say he was going to machine it

reread the post;; I believe the two side by side ARE machined.

Ok, next question for the day.

How do you get injector seal washers out.  I have 4 out(fell out).  Two are stubborn.  Used a wide screwdriver and tried to tap into copper and twist(read that somewhere) but nothing.

Thoughs?

are the heads still on the ground as in picture ??? if so a rat tail  file BY HAND tap in and twist. check file diameter using old washer that is out. don't want to damage injector bore. also install   file in injector hole in head to double check clearances. don't remember if the brass washer hole dia is smaller then on heads, small socket/ flat punch from bottom side ???

[Freightrain]

Heads still on floor.  Almost bolted it on until I realized two seals still in the head.  Tried screwdriver, the through hole is same as cup so no shoulder to catch on.  I tried different size drills to see if I could use one to push up.

as a last resort since all others failed. a small sharp chisel :yep . pros VS cons . two notches across from each other . sometimes the washer will bend up ; down side there is also a chance to expand the washer tighter. have done the chisel route with success. since heads are off no contamination in cyl. never tried this BUT small  hole saw to weaken washer. pull that one off your qualified to do open heart surgery!!!

[mechohaulic]

attempt the chisel route; we are talking LIght tapping ; be a mess to blast out the head.

there might be some good in the hole saw idea:::  7/16 + - saw having a 5/16 guide will keep saw centered in hole; the saw will weaken the center of washer  unlike using a drill which could possibly damage head. another topic having the "wish I was there ".

Don't forget, there is a reamer once all washers are out, for the injector bores.     terry

I used a stiff oil galley brush to clean up the bores.  Not perfect but pretty clean.

 

I will test fit injectors when I get them back.

I know it’s your call, but with the trouble you had getting injectors out, i sure would try to scare up a reamer🤷‍♀️. terryespecially since your doing a proper overhaul?

Can’t stress enough! Never seaze ! How ever if you’re like me you will not be worrying about removing them ever again! Your looking after the next guy!

interesting the topic of never seize hasn't shown up before this. always did the never=seize on the injectors before install. caution given during application  don't want the seize going down barrel going between injector and brass washer ,lube 90%

I may look at work and see if there is something useable.
