Slide Hammer and Adapter for HD6 Injectors

 

In my experience with our AC 45 grader you don't need elaborate.  And I presume your injectors are similar.

 

I pulled ours with a home-made one.  The threads where you pull seem to be metric (22mm I think but won't check tonight as it is very wet).  Anyway you can cut them in a piece of 3/4" waterpipe.  And then raid the scrap pile and make your own slide hammer on that.

 

Re the wet - we've had record rain and record floods here.  Personally pretty much OK but local towns aren't.  Phones and internet off for 2 days. 

 

I've just checked the tap size - it is 22 x 1.5mm metric.  You're on the right track for the rest IMO.

 

You only have to take the cap off the injector to get the threads for the puller. 

 

We had a selection of 15 injectors and got 8 useable ones from them.  So I haven't been into nozzles etc.  Minnpar say the book ones for the AC 45 are not available, but a contact here got some for a HD 11 ex Germany.  Other sources also suggest that they're available.

 

Incidently in the search for Torrington bearings for our grader steering I've found a local parts shop that can go from Allis numbers straight to Torrington.  They have an old I.B.I Bearing Crossreference book.  And our FA 10 parts book has a table at the back that goes from FA bearing part numbers to standard bearing talk - very handy.

 

 

 

And if you want an "official" Allis injection pipe nut spanner (wrench) for Am Bosch rotaries like you should have on this if I'm reading right.

 

Get a picture if you can so you can see what the original looks like.  Otherwise you'll be trusting my take.  Then 

 

Start with a long 3/4" socket.  Leave about 1/2" at the bottom on the 3/4" hex end.  Then chop out from there to about the bottom of the square at the top to a bit more than halfway through the socket.  (I did it with a thin cut-off in a 4" angle grinder). Then slit the bottom hex so it goes over the injector pipe.  And then grind so it clears the pipes and goes between the nut and the centre dome on the injector head. 

 

Works on our AC 45.  Perhaps doesn't look as fancy as the original.

Note to Jay: I am pulling the injectors because the 6 I purchased has a seized block.  Before further surgery like pulling the head, I want to remove the injectors and fill with some ATF, kroil and maybe see if I can free up the engine.   

I think if you have lots of smoke on start up that the injector spray pattern may be off. 

Good luck - Orangeman!

 

The engine manuals have acceptable spray pattern diagrams (on test bench) and tips on cleaning etc.

 

Endurancepower list complete injectors for the Buda types and options for the later engines - don't know how current this is.  And I saw another source which I will have to track down.
