The taper alone on the flywheel determines how far the flywheel pulls up on the crank. The inside part I suggest cutting would only prevent the flywheel from pulling up the taper far enough if it wasn’t cut. The taper is long so cutting off the inside has no impact on the job the taper does. Make sense??

Danny C Yes. This could very well be the problem. It probably is still grinding some getting into second gear too but not as loud. First gear is spinning faster which is why it will grind more.

@@gregwold8889 thank you for your response. This is our first time doing this and we were quite lost. We will give this a try. I will keep you posted.

Bill yes. Most likely the case

Possible, yes. Very difficult, yes. Pulling the flywheel while the engine is in the car is very difficult but possible. If the flywheel is hard to pull off which is often the case, there probably isn’t enough room to get a good puller in the space available to pull the flywheel.

thanks! I have just removed the fly wheel today and am looking to take to to a clutch specialist tomorrow. Is grinding these out something common that people do? What is the measurement I need it grinded too? Cheers!

Cohen White Yes this is a common thing to do, especially on engines that may have been taken apart a few times. Cut back the inside of the flywheel 0.020-0.025”. There is plenty of flywheel there so this amount won’t make a difference.

sprokthered The scratch most likely is from the flywheel wobbling on the crankshaft. The fit was loose and the rocking action caused the scratch. The scratch may be the start of a crack too. I am a “do it right” person. Take it apart and magnaflux the crank and make sure that you don’t have a cracked crank. If the crank is fine then you can use valve grinding compound and work the flywheel and crank taper surfaces together. Make sure to cut the inside of the flywheel as this video suggests because the crank will travel further up the taper.

Greg Wold thanks for taking the time to get back to me.

About 0.25mm will be enough.. Hard to measure as you can't see in tehre to measure, but start by taking off 0.25mm from the inside of the flywheel...

My daughter hiked and camped Patagonia a year ago from Minnesota, MN. She thought it was beautiful!

I wish I had a solution for you. It seems that if you replaced those parts, then you should have fixed the problem. First guess is that the clutch disc had oil on it, but you changed that. It could be two things. If the flywheel and pressure plate aren't matched, it is possible that the strap bundles holding the flywheel and back plat together are the problem. You should have at least three straps in each of the three strap bundles... So at least 9 total straps or 12 straps (4 per bundle) if you have them. If the straps don't lie flat when the clutch is in its normal position (the clutch is engaged, foot off the pedal), that could cause some vibration too. You need to set up the flywheel on the bench before putting it in the car to make sure that the straps are lying flat and just touching the ears on the back plate. If not you will have to ship the straps up or down with washers so they are perfectly flat and just touching the ears on the back plate.. Wish I was there to help out...

Thank you very much. Regards. Please, 9 straps ??? See 1strap in es.tinypic.com/m/j6jv5f/1 Thank you very much

+Your clutch problem is exactly as I explain in the TH-cam video... Pull the flywheel and machine off the inside to give clearance between the flywheel and the primary gear... Trust me here.... This should do the trick...
