My gf wants to play with my end....sooooooo....how do i check for endplay in my crank? (the one on the jeep...lol) How much should there be? I bought a feeler gauge....just becz i liked the name...how do i use it??
Cool on the feeler gauges. Should be part of everyone's tool set. They are the most basic way you can measure all kinds of clearance, thickness, etc. Not just crank ends. Been around for a hundred years.
Here's how ya do it:
Get a big fkin hammer and whack the end of the crank, straight in lengthwise. Just one sharp rap.
Now take your feelers and try to start slideing the different thickness blades in between the cheeks of the crank (the counterweights and rod throws), and the wall of the block. Usually you can do this against the side of a main bearing cap. Some guys check all of em. "How much clearance is between the sides of the bearing caps and the side of the crank?" - is the question to ask.
A bunch of the blades won't fit into the gap. The fattest one that just slides in edge-wise, that is your end-play clearance. Kinda liike trying to slide a sheet of paper edge-wise.
I wish I had a pic of it to explain it better, but once you see it, its totally easy, only takes 5 mins.
Specs are from .002 to .006 gap
. Remember one side is gonna be zero, the other side is gonna give you your measurement.
ETA: This is one of the specs that sets your oil pressure - Tighter the clearance = more the oil pressure
