I prepared the engine head for painting. I will apply black tomorrow

[paul.jameson]

One of those heads will fit easily. The other one will be most difficult!!!

[Karol Burger]

the other head is for my Ariel 500 ohv model E super sport 1927 when I have a moment of time caused by waiting for some parts of 4F, I also work on other projects

[Karol Burger]

the sun has finally shone, so I start painting

[Karol Burger]

I started assembling the parts of the head. the old bearing was folded with a case. They probably couldn't buy a bearing in inches.

[Karol Burger]

I cleaned the drain channel and want to try to use covered bearings. this method should retain more oil for the camshaft. I'm just afraid that the 2 drain channels won't have time to drain the excess oil from the head and the motorcycle will start to smoke.


.
have you ever used covered bearing heads for 4F ??? can i tell anyone have tried it?

[Karol Burger]

the camshaft will float a little in the oil and the excess oil will be discarded to the valves. From there, it should drain through the canal.

I just don't know if the oil dosage is not excessive in this model and then it may be desirable for the oil to drain through the bearing

[Karol Burger]

most valves seem to be fine. two seemed damaged to me, so I replaced them. I sand them with a paste and fold the upper divorce

[Karol Burger]

I have ground the valve seats, assembled the springs and will wait for your advice on whether I can keep the camshaft bearing covered or whether it is necessary to remove the ball cover.
