Tony, I thought I had sent them to you long time ago. I guess I am getting old and have even forgotten what the word remember means...
Up to Engine number SJ 86045 E, CAV BDN 12SP 6169
Engine number SJ 86046 E to SJ 125724 E, CAV BDN 12SP 6262
From Engine number SJ 125725 E, CAV BDN 12SP 6290
Opening pressure is 130 atm for old nozzles, and 135 atm for new nozzles.
Tony, I have sent the squirt pattern for the 23 C injectors in a mail to you. Find included a Word file to open.
Some says the engines with the separate heater plugs had a different nozzle than the engines without heater plugs.
I have been looking in my MF 35 parts manual, and in my shop manual, both original MF books, and I have also been into the AGCO parts book system, and I find different nozzles, but they are all related to engine serial number, and not with or without heater plugs.
The nozzles has a little unique spray pattern, they are supposed to squirt out very little fuel straight forward when the engine is cranked by the starter even at full trottle, but when the engine starts and the speed increases, the squirt to the side deminish, and the squirt straight forward increases.
You'll see the pattern in the file I sent. I can't understand I haven't sent it to you before. I need to go and get my head examined.
Something must be wrong up there in what do you call it.
