thanks, I guess I will open them too. those passages didn't seem so clean at all. I don't have every right tool so I need to figure out something to open them.

You need just 2 skrewdriver. With bigger one you press piston down 1mm and with smaler one you take snapring out. Little magnet will help you to take piston and valve out from lifter.

After you have assembled lifters back together sink them to motor oil and pump few times piston to fill it with oil. You can feel when piston wont compress anymore, then its full.

sure, thanks for the tip, will do that. for now they have wait since I can do that as very last step before closing the valve cover

finally got the shift fork rail out. have been fighting to take out that pin (in picture). took it somewhere too but the guy there didn't have any idea and said it has nothing to do with that pin. so came back home, checked the diagrams for np242, the pin was the only way to get the forks out and kept fighting till I find the right screw.

there is slight damage on side where the front output fork sits on the rail. can it be my shifting problem? it was getting stuck when switching from 4x2 to 4x4 high/low.

managed to clean up the cover. it wasn't that easy though. did a bit sanding inside and outside to get smoother surface and painted.

time to have hot bath washed the engine block and transmission with pressured hot water. pressure wasn't enough ( Karcher K4.99 ) but still did a good job, something with 160 - 180 bar would do a lot better though. that W5 cleaner made it a lot easier. yes I did lubricate after washing it with water. don't want them get rusty.

oil passages around lifters got cleaner that I could notice them. and did a bit honing on piston skirts since there will be new rings coming.

yet couldn't remove the pulley, I don't wanna heat it up to pull out, waiting for pulley removing tool. probably will get it soon.

removed the pulley and got the everything out from the block. meanwhile ordered a new timing chain.

did one more cleaning round before painting.

[sms1878]

painted the block to red

will do one more round tomorrow.
