Merc 900 valve Springs and lifters
 

Anyone know who made the springs and lifters for 900's ? Want to source everything before we pull it apart.

call me before you buy Jamie... I might be able to help you

Is that the crane solid roller 252/257-672/672

Sounds about right

I use comp cams springs for replacement. For seasons and no problems. I put new Springs in every spring

Happen to have a part number ?

Which comp springs? I only did a quick search but couldn't find any comps similar to the recommended crane spring #99876.

160 closed @ 1.968
468 open @ 1.348

Seems pretty light pressures for that cam but it's what the card shows.

That's way light for a 6200 rpm solid roller sc engine imop
Where did you find that? Per the camshaft recommendation?

Right off the cam card. I hear ya. I've used way more spring on hyd roller cams with solid lifters.

Makes no sense I know but pm me your ph number and I will tx you cam card.
