Nice project Akbar bhai. Work done very well. Two thumbs up for your Cousins efforts and your keeping us informed all along. Thanks.
I was going to suggest using the WD-40 spray for removing the Bolt from the bottom of the engine, I guess you guys have already done that, as one Spray CAN can be seen.
Really, this practical work, get all of us Pakwheeler get involved and geared up to do something ourselves. I have changed the Air-compressor, the brakes, the rotors, generator, belts, installed modified high amp 2000 watt deck system with box speaker etc. on my car myself, some time back.
Its alot of fun and rewarding, once you finish the work.
Nothing like the smell of dirty old oil and grease, it motivates you more to get the work done quicker.
It always takes long time in first attempt, but the second and third attempt you become faster and more proficient, in any project, job.
