Hello Peter, Don't take too much off the cylinder registers, There is not a lot of alloy between the top of the cam spindle hole and the cylinder base, It could crack open, Cheers Bill.
This appears to be one area of the cases which have not suffered too badly, the holes are all standard & tight!Hi there PT, are your spindle holes standard (worn) sizes or have you machined them oversize....?....Greg.
A bit late on this one. I would look at the inside of the timing cover where the discs go, compare the sizes of the orifice. If the existing holes are bigger than the ones in the discs, I'd reckon to fit them as you will get more oil to the big-end. Remember these are low pressure jobs. Roy.I see in TASL that ET234 oil restrictor discs are optional. How does one know if they are required? Run the engine with them fitted until something squeaks then remove them, or run without them watch for smoke??
Thanks Les, I didnt realise that I had such an adoring fan base!Pushrod have you finished your project
I'm missing your posts
Can you believe looking at a crank with crappy old mains bearings full of coagulated 30 year old Castrol R that you would find a new Alpha big end bearing lurking inside?
