Thanks for a very clear presentation especially on the timing marks on the flywheel and timing sprockets. They can be extremely difficult to find in very old engines - about 70 years old. In my experience it took a lot of cleaning to expose them. It would be much easier if I knew exactly where to look.Jim Hehir
Thanks for your comment Jim. I hope this video has helped a bit then. Yes on the older engines they weren't as diligent about the marks and didn't make them quite as easy to see.
Hello Gordon you are looking a wee bit furry. We may need to start calling you Bundy Bear II by the time the tractor project is complete. Good job getting the engine ready for teardown. I'm sure you will find some interesting things to teach Oscar regarding the details of an internal combustion engine. TTFN/CDC
Hi Richard, the weights are part of the engine governor mechanism. As the engine speed increases the weights are forced outward by centrifugal forces, lifting the dome shaped cup in the centre which in turn operates the lever in the camshaft cover. This is ultimately connected to the carburettor throttle. When the speed slows e.g. when the engine comes under load the weights move inwards, increasing throttle and hence stabilising the engine speed. The movement is quite minor and it’s only capable of compensating for increased load up to a point after that the engine will slow and eventually stall if the load continues to increase beyond the governors limits, but it is usually enough for the usual operating parameters of the tractor. I think we cover aspects of this in the camshaft reassembly video. Hope this helps. 👍😉
Hi! Did u have a video for changing the 3 seals of the timing casing both because I have a 2 big leaks here and I have no idea how to remove the little one of the gouvernor
Hi Vince, sorry I don’t. I didn’t need to replace mine as it was still fine. Lance @ Bundybears shed did one a few years ago. I’ll see if I can find it.
Just sayin Gordon, Another 150mm on that beard and not only will you be good lookin like me but you wont feel the cold, lol. If you use a 1/4" punch it will be a tight fit in the timing hole and there are 4 places. If the rockers are still on the rockers on no4 will be rocking.
Ha ha - my winter coat! I don't think I could ever compete with Mr Hollywood! Thanks for the tip - I will use that when re-assembling. Thanks too for the plug on FB!

Thanks Charles, ye I thought I’d let it grow a bit. In the end the family couldn’t get used to it, so it’s gone again now! I liked it 😉👍
Nice job involving the your lad. What are the weights on the camshaft sprocket for?

Take a look at Video #103.
