New Woodruff Key and bearing on. Yes I had to tap the key a bit more to get it level, I found that out when fitting the timing gear
Talking of which;
Fitted on all went smoothly aside from my first attempt at the timing gear due to the woodruff key and not enough heat. When fitting this gear make sure that the groove/recess in the one side of the gear goes towards the bearing.
If you are wondering what I used to heat the gear evenly:
First use that had in about 15 years! still had gas as well so that was nice.
Don't forget to remove this little git from the flywheel and replace it, this was like plastic. The flywheel isn't grooved that much, there is a mark there as you can see but my nail doesn't catch it when running a finger over it so I don't think it need a sleeve.
Hey wow what happened here???
As you can or cannot see some of the stud threads are a bit mullered, ran over them with a nut and some oil going back and forth carefully to clean them up as I don't have a die/tap that will fit. As I wasn't planning to remove all of these studs I never took a detailed picture of them, it was a bugger when I got them back because looking through the Bentley manual and figure out what went where was a bit of trial and error. I
think I got them all right as when I put the case together they all have enough thread on them with none sticking way out or not enough out, if that makes sense. As much as the initial "bugger they bent one" and then the straightening out of said stud, finding where they all went was actually kinda enjoyable... I mean what's another job right? maybe I am a masochist.
Got all the new bearings on the crank, made sure all the bearings were aligned right with the tangs seated right and also the number 4 bearing has to have the oil groove towards the pulley and also has to lign up with the locating dowel in the case which was slightly fiddly. One thing I forgot to put on next to the number one main was the thrust washer. Got to remember to plonk it on when I do it all for real!
Enough of that anyway, I finally unwrapped the new shiney cam (thanks Andrew) Plonked in the new bearing shells had to dig out a fine file to file down the one tang that needs to be removed. When doing that I ended up putting some thick tape over the bearing to make sure I didn't damage or file anywhere that would have caused a problem.
Now this is a test fit so I won't be bolting anything down yet, as the rods have to go on and I am awaiting the gasket set. When spinning the crank the cam follows nicely and doesn't lift out at all. There is no clunking at all and it's all very smooth. I haven't measured backlash yet because I misplaced my feelers.. I did find them but was losing light and getting hungry so I will do that tomorrow!
Made sure to get the gears lined up, not that It matters I suppose for a test fit though. Oiled up bearing contact surfaces and put the other case half on, yes I remembered the other bearing shell halves!. Case half went on nice and snug nothing seemed to have pinched. Couldn't get my hand in the case to turn it by hand as I'm a weed so I put the pulley nut on and just turned it with a spanner. All span fine, granted I didn't have anything bolted down just push fitted. Should it spin really easily without much force when the halves are together or should there be some weight to it?
Don't think I've forgotten anything. Tomorrow all being well I will tackle the rod installation, I did wipe them all down with petrol and some rags so they are nice and shiney now, currently all sitting in some clean oil. Although with that do I need to get another torque wrench for those or could I get away with my ratchet type one.
