Does anyone know if the rear tires on an A-C M100 grader have to all be the same type and size so the drive chains and drive train are not stressed? Are the axles locked as they are on the Model D?

How do you remove a fuel injector on a A-C 11000 engine from the head? Just remove the two bolts and then wiggle it until it comes up and out, or does it require specialized tools to do it?

Thanks

You are asking about the Nozzles, in the head?  Fuel Injector system is in the Pump, the Nozzles are just delivery mechanisms.  Take the nuts off the studs, will need a Slide hammer in most instances with a tool under the nozzle retainer ears to get them out.  Carbon bypassing the tip area and contaminates seeping in around the body lock them in place tight enough is no wiggling them out.  Will need to clean the bore and seat when reinstall or will not seat properly, will be a copper washer at bottom of bore or stuck on nozzle tip.

If want least amount of drive train wear or excessive pressure, yes all four tires need to be roughly same diameter.

If the nozzles are like those in an AC Forty Five you can take the end cap off and screw a slide hammer adapter on the end.  IIRC 22 mm coarse thread.

To you both, 

You understood my question better than I wrote it. That is exactly what I meant to ask regarding the method for removing the injector nozzles.

I had not thought of using a slide hammer.  I was thinking of using a cold chisel under each of the tabs and alternatively tapping on them until the nozzle broke loose. 

It is good to see that there is a consensus about using a slide hammer to get it out. As with solutions offered sometimes, they have some pretty "imaginative" ideas of going about doing things.  

Screwing a cap on it would work fine as I am not too concerned about damaging the nozzle as I have located someone who has NOS of them. But good to know that the cone has to be cleaned out.

I will also check the circumference of the tires to make sure they are the same I see that one of them has a different tread pattern so it might not be the same. 

Thanks

I actually made a nut that screws on the back of the injector and connects to the slide hammer.  There should be no damage to the injector body at all.

And the "official Allis injector pipe nut spanner" makes working on the pipes at the pump easier.

I posted here maybe 10 - 12 years ago on making one out of a long socket with creative use of a thin cut off wheel.


And another post further back from that
