It's a 7:1 ratio, you do not have to remove the gear to align it properly, just take the chain off and spin that gear set until it's on the timing mark. Great video and love that you cut the block to show the internals 🤘
I find this funny. Just follow the normal procedure for chains on a ccta and put everything at tdc, when you re time the motor your using the colored links on the chain. You're making it wayyy more difficult than ot actually is.
Great demonstration by cutting away the part of the block showing how the balance shaft can be out of time! I’m looking to reseal the leaky head cover on my mk7 gti and I’ve fallen down the rabbit hole regarding timing and whatnot with these ea888 engines. Great videos, thank for the help!
I understand what you’re saying but it’s not correct. The VW repair manual doesn’t mention any of it either. The two balance shafts rotate together so their weights have to be rotating together where you put the weight doesn’t matter. As long as the dot on the inlet balance shaft sits in between the two dots on the sprocket and the copper links are on the dots on both balance shafts, those balance shafts will then be working in perfect harmony with each other. If what you said was correct then everytime you turned the engine off you would have to turn it off so that the weight on the balance shaft is downwards, which makes no sense. Bottom line is: if it’s all in time, it will rotate in perfect harmony with no vibration.
Can I ask a question im regbuilding my cczb engine re using the old balance shafts but the spur gear on the inlet side is meant to replaced due to back lash limits as new ones are coated. Do you replace? I can set back lash by moving it slightly but whats a good setting ive got it a 0.2mm has slight play..just seems stupid to replace for back lash if you can set it.any help welcomed
