Sirji excellent job. full of infomation. I m 75 yrs old & sailed as R/O fm 1968 to 1998. its my hobby to learn new things related tomarine field. tks again.
Sir I highly appreciate ur intrest in learning......Am honoured to read ur comments....Hands off for your mindset to be in touch with the marine engineering. Thank you for ur words...
Thank you for sharing your knowledge. If there is a chance can you make also a video of overhauling for fuel pumps, LT and HT pumps, LO pump and Air cooler of Aux Engine. Thank you! Safe sailing!
For compression pressure just make fuel pump rack to zero ...no fuel should be admitted to unit....and note generator should not be on load to avoid unnecessary deviations in other unit...check each unit one by one by pulling the fuel rack backwards
Hey while reliving stress of bolts i observed that the bearing shell was not there and marking was done....how did the marking match while installing in the engine???
Hey appreciate your comment and sorry for late reply.. While reliving the stress of the conrod bolts the bearing shells must b out and markings should be done as described in the video. This is to protect the new bearing shell from getting damaged in bench vise while tightening the new bolts,The bearing shell material is of white metal and is comparatively much softer than the connecting rod material , after installation of new bearing shell the bearing gets compressed into the groove and doesn't affect the markings made during pre tightening.
Hey thks for your compliment.... appreciate your words.. The AE decarb job usually is carried out at 8000 operating hrs.. Connecting Rod bolts to be renewed every 16000 Operating hrs..
In yanmar engine piston has holes underneath for piston cooling by oil . In manual it’s clearly mentioned that perforated hole must be on fuel pump side , why it’s so please explain 🙏
Check lub oil passage from con rod to piston and after exit and see on your own think about purpose by keeping in mind the rotation of engine forward and oil splash is required or do these holes simply to drain oil directly to sum p without touching con rod
Firstly it's good to hear from ur end...means u watching the video carefully.... appreciate that.. Usually if u keep all spares ready,just like spare cylinder heads,pistons,con rod .....than u can complete the job with full E/R team in 5 days....
Yes I am watching Your videos carefully and I understand it nicely because I am Diesel Mechanic also and I saw Your all videos which is informative,keep up the good work Sir 🎉
U absolutely right...and I do apologise for the mistake.. M happy that u saw the video so patiently and can say...u know the job...thks for ur comment...
@@sealegend1627 hey it's ok sir np.. tbh we did our 10k hrs overhaul by following ur video only. That time i missed this ,now for class 4 preparation i was watching again.. Thanks for making wonderful videos👏
12:50 If the roller is on peak of the cam then how is this compression stroke.. exhast valve and suction valve will be open... just confused... should be on the base of the cam
Firstly thanks and I really appreciate u for watching the video so deeply..... U absolutely right brother....the roller should b on base of the cam during compression stroke... Thank you commenting...
Bhai first time I m working on yanmar..Dearb is due thank so much for video ...great help God bless you
What a video Bro...years of knowledge and hard work you summarize in 30 minutes..thanks.. really too good
Thank you for your sharing marine knowledge
Way way way tooooooooooo good… Such a clear explanation with demonstration … Thank you for sharing the knowledge with us..

Very informative video 👍
Thankyou for this informative video.
Very much well explain video sir.. Keep creating much more. If possible sir pls make vide on main engine Decaronisation.
Thank you for sharing your knowledge. If there is a chance can you make also a video of overhauling for fuel pumps, LT and HT pumps, LO pump and Air cooler of Aux Engine. Thank you! Safe sailing!
Very essential video for beginners
Thank u very much.pls upload more video on generator troubleshooting and how to take compression pressure and how to take deflection of crankshafts.
For compression pressure just make fuel pump rack to zero ...no fuel should be admitted to unit....and note generator should not be on load to avoid unnecessary deviations in other unit...check each unit one by one by pulling the fuel rack backwards
Superb bro..
THANK SIR ,YOUR VEDIO IS SO GOOG AND USEFUL
Very informative...!!!
V well explained bada shabb
Great job
thx for sharing sir
Very informative video
Thanks sir
Wawwwww
Thank you sir 🙏

Very good
Thanks
Nice
Thanks
Because of rotation of engine
Great work !please keep making overhaul videos with so much clarity kudos!!!

idol,thank so much for this vedeeo,but i have question,may i nkow the frequency of decarvonization of engine ?
Hey thks for your compliment.... appreciate your words..
The AE decarb job usually is carried out at 8000 operating hrs..
Connecting Rod bolts to be renewed every 16000 Operating hrs..
In yanmar engine piston has holes underneath for piston cooling by oil . In manual it’s clearly mentioned that perforated hole must be on fuel pump side , why it’s so please explain 🙏
And is this hole is for draining oil from piston ?if yes it is done so that oil can splash during rotation by con rod movement for liner lubrication
Check lub oil passage from con rod to piston and after exit and see on your own think about purpose by keeping in mind the rotation of engine forward and oil splash is required or do these holes simply to drain oil directly to sum p without touching con rod

Hi sir,
Is it possible to relief internal stress of bolt by heating or annealing process?
No once deformed it has to be replaced with new one...
How many days it took to overhaul the Genset?
Firstly it's good to hear from ur end...means u watching the video carefully.... appreciate that..
Usually if u keep all spares ready,just like spare cylinder heads,pistons,con rod .....than u can complete the job with full E/R team in 5 days....
Yes I am watching Your videos carefully and I understand it nicely because I am Diesel Mechanic also and I saw Your all videos which is informative,keep up the good work Sir 🎉
4 guys can do 2 unit per day...and other crew is required for cleaning and removing carbon ....
12:49 how come on peak of the cam when taking tappet clearance
U absolutely right...and I do apologise for the mistake..
M happy that u saw the video so patiently and can say...u know the job...thks for ur comment...
