All,
I am waiting to get my new Injector Pump for my 224. While waiting I decided to read up all the posts on Injector timing. Well there are not too many.... I went to JohnsTractor site and read his posts but that has only gotten me confused.
Please feel free to correct me in how I understand the procedure works.
Assumptions
1. New injector install
2. I can't find timing marks on crank pulley [where are they???]
3. Marks on injector gear and cam gear do not line up as described in engine manual. Must have jumped out when injector pump seat broke.
Procedure
1. Place engine at TDC by turning engine counterclockwise until #1 intake/exhaust valves push rods spin freely.
2. Install new injector pump onto engine block
3. Install gearing onto injector pump shaft, leave bolts lose for adjustment.
Now here is where I get confused.
4. Unscrew #1 hard line atop injector pump
5. Advance engine 18 degrees by turning pulley counterclockwise [how do I know where 18 degrees is?]
6. Watch for fuel welling up in #1 fuel port. Fuel should well up if not fine tune injector timing with the 3 bolts on the injector gearing, either advance or ****** the injector timing.
7. Repeat steps 5 and 6 until timing is dialed in.
8. Reassemble all remain parts, bleed fuel lines and start engine.
9. Observer engine running, looking for excessive black smoke, injector timing needs to be retarded, or unusual knocking, timing needs to be slightly advanced.
10. Button everything up and I am done!
Now what am I missing, what do I have wrong? Any tips you can pass on? Should I not even attampt this on my own?
