New CAT Air compressor Locked up?

The motor was overhauled by cat in 2007. Its a dump truck that has many many many idle hours and nothing but heavy pulling and had snot beat out of it. Has about 400k on the rebuild. goes through 2 gallons of oil every 10k. I was planning on doing a c15 swap next fall or just overhaul this one. Not sure.
So thats why im not trying to invest too much time and money in this mishap. Just want to slap it back together and run it one more season. I understand what you are saying and i would 100 percent agree with you if i was planning on keeping this motor going a couple more years.
Your thoughts with that being said?

 

Also, whats the deal with the idler timing marks. when i put the truck top dead center on compression stroke cylinder number 1, The idler marks never wind up where the manual says. If i repeat the process which i did ten times, They winmd up in different spots. The cam and crank nothces always wind up in exact same spots. Also verified both intake and exhaust valves closed. The more i thought about it, it just seems like physics is the reason. Are the notches on the idler just there for the first install?

 

ok i think maybe you guys are right even if motor is old. Dont think my puller will fit in there. supposed to be here tomorrow. You think my oxy and acet torch will work to pull gear off? ITs going in trash anyway. HEat it up cherry and slip right off?

 

yeah i edited my last post to pushbroom. Dont think my big puller will fit between housing and cam gear. will heating up the cam ghear to cherry around where slides on to cam work for removal? Its trash anyway. Slide right off?

 

yeah thats what y cat manual says also. ill do what i can. Even if i have to remove cam. Thanks

 

ok you guys talkd me into. Ill do wht i can to get the gear off.
