You really need to remove engine pull start shroud (4 bolts) to determine top dead center. TDC is marked on flywheel by a hole Then adjust valves to .15 mm gap
Thank you for this video! I hope also it's should be the same procedure and valve settings for my F192FB Diesel Power Generator as it from your video! Thanks Dude!
nice and clear but there is a little doubt why not test after doing tappet..😁 but still i like the way you do while explaining its purposes..nice thumbs up
Interesting. My very similar D475E diesel engine is claimed to need 0.1 mm inlet and 0.15 exhaust. If it is so critical, I am now doubting what Hyundai tell me about the valve clearances...
My exhaust is blowing out flames and has melted the flexible exhaust connector. The valve clearances are good. Why would the valve be opening when there are flames still in the cylinder?
Hi, these engines (thousands of them) are all based on the Yanmar YDG Series - you'll see 170F and 186F, 186FA and very similar, but mostly with 186, sometimes 170. Aurora is a Canadian company and they use the 186FA (I think), the Chinese push out lots of different brand names, but they use identical engines, and generator numbers, depending on the electrical output. If you want the manual for this engine/generator, the best I have seen is Aurora's - do a search for "AGI6500DE & AGI6500SDE Operator / Owners Manual Version 11.4.1." It is a very good manual, far better than most. People have trouble finding the valve clearances - really simple, they all appear to be 0.15mm for inlet and exhaust. I am certain of this because I've researched many sources. I'm in the Philippines and I can get most simple parts like gaskets, AVRs, fuel pumps, piston rings and injectors very cheap online - again Chinese copies of the genuine Yanmar parts. If you need bigger parts such as a piston or crankshaft you can usually order through the larger industrial hardware stores.
From the Aurora manual "After the initial 25 hour break in process, synthetic diesel engine lube oil 5w40 to 15w40 is required." Don't used synthetic before 20 hours because it can gum up the cylinder - use regular diesel oil. You can download the manual by searching for AGI6500DE & AGI6500SDE Operator / Owners Manual Version 11.4.1. It is a very good manual, far better than most. For the diesel deep knowledge search for "Yanmar 170F manual" and click on the manuals.lib link - it is free and massive (about 170 pages If I remember right) - how to strip down the engine and reassemble. Don't worry about the names - the Chinese (and Aurora) ripped off the Yanmar YDG series. They are all closely based around the 168F and 168FA engine gensets. For your valves, both inlet and exhaust are 0.15mm/0.006" - some references say .004' inlet and .006" exhaust, but they both include 0.006" in the their ranges, so 6 thou is given by most sources - it's what I use on my father in laws 3500W gen and my own 6000W (both 186F engines).
@@lyndonlawas2367 Hi, I disagree. I have spent hours over the last few weeks researching 186F/FA engines. Some sources state 0.1-0.15mm (0.004-0.006") inlet and 0.15-0.2 (0.006-0.008") exhaust, but most state 0.15 for both. 0.15 fits both ranges, consequently most sources go with 0.15mm/0.006" for both valves. I'd love to know where your figures come from because they are an order of magnitude out. I've just adjusted my brand new 6kW gen and my father in laws 3.5kW gen to 0.15mm and both start and run perfectly with no noticable tappet noise.
I've had one for over 5 years abusing it. it ran over 12 hours (sometimes 24+ hours) a day for 5 months straight and it's still pretty much brand new. running a/c's, microwaves, computers, tvs, and even saws and welders. these little things can take more abuse than people think.
