Hi.
While carrying out an oil change, I have removed the ball and spring from the lower part of the timing case cleaned and is ready to be put back.
My question is, the manual states not the exact words but give the ball a sharp strike to seat it. Not sure how hard and what to use. I have a steel flat end punch that will fit in well, but will it damage the ball then causing seating problems. I was wondering if the best thing is to just replace it as is. It came out with a magnet so was not jammed, and clean.
I have had a reply about my sump leak and did not understand all of it. The gauze, is it in 2 halves? and should I use jointing compound. Is the paper gaskets ok or is there a betted type?

What was said was that oil will not leak through the gauze. I know it is full of holes but if you attempt to look through it side on you can't, neither can the oil. I use a paper gasket each side of mine with a sealer. Your choice with that.
I re-seat check valves with balls in them at work quite a lot, and test them up to 5-600psi... I find case hardened balls very hard if not impossible to mark - stainless ones will get a flat on them from the punch so if this is the case I will use one to form the seat and then put a fresh one in.
The seat for the ball wants to be very narrow, pretty much a sharp edge to start with. Not sure how they wear on our bikes but seats can broaden over time which reduces their effectiveness.
A couple of questions please ....
1-What is the function of that ball and spring assembly, I just cleaned mine and put it back togeter after putting the timing cover back on the other day but not really sure on what it does or how it works?
2-I had assumed because there is a spring holding the ball bearing in place the bearing is just meant to have light presure on it, what would the purpose be of seating it with a strike of a hammer, would this not maybe cause the bearing to stay in the closed position?
Thanks in advance.......wayne
It is supposed to be an anti-drain valve. Tapping the ball on the seat is supposed to help seal it better. Most oil drainage into the sump is caused by wear in the oil pump.
