Full Floater

I've had excellent luck taking an air chisel (carefully of course) to someone on the injector body/flange and getting a heel bar prying up under it at the same time. worked like a charm on injectors that would NOT budge otherwise

Seen an 855 Cummins do this after its 4th overhaul. Curious if it's been overhauled recently and the wrong rings or pistons installed.

Got ahold of John. What a wealth of knowledge and a great guy to talk to. He does have a gasket set for my 866!

Thank you

Have you spoken with him recently? Google says permanently closed on their listing.

Back up and running 100% Thanks for the support fellas.

Im not actually sure

Any tips to placing the fire ring in the new head gasket? Been a while, can't for the life of me remember using any sealant to hold the fire ring in place or anything. Thought I'd better ask. Here is a pic if the peened seats on the donor head

Split the screen??? Im quite the slow poke when it comes to technology.

I keep getting an error code 200 when trying to upload a pic today, but on my parts head that is going on, the exhaust valve seats have some peening around them. Was this factory? I haven't noticed before, but also never paid much attention. Haven't pulled the bad head yet to look at that one. I know this parts head has been off before years ago for an inframe, so maybe something was done to the seats or someone peened them to prevent them from falling out. I will continue to try to upload the pic until it lets me

Thanks fellas!

Needing to do a quick and dirty front head swap on a 237 for someone here quick. It has a loose valve seat on cyl 3. I have a couple parts engines. Are the front and rear heads interchangeable? Just curious so I can use whatever appears best after pulling them. No time for sending it away for any machine work. I guess there's nothing much that can be done with the existing seats in the donor head to help prevent them dropping, is there?

Excellent heads up on the cracking heads. Thank you.

Any chance that it's sucking air into the fuel system, or fuel restriction?

Excellent. That makes the project more realistic, as I'm sure the bolts are getting hard to source also, AND likely quite pricey!
