Valve adjustment issues

[He Man]

While doing my valve adjustment, i saw this scar on the rod that holds the valve arm.
Any idea how it could of happened??

Is that a 'scar', or a groove to let oil in?

yea i just checked my haynes manual. i feel dumb. if thye are going ot make a groove like that, they should make it look nicer. mine is all jagged everywhere.

now i just have to figure out why my closing shim doesnt just drop to reveal the collets when i push on the closing rocker arm.

I installed the collets on one of the arms but theres a lot of binding  and theres no way for me to measure the correct size without buying a whole kit and seeing which one fits best.

Give it a little tap to free it.

Stop thinking like an engineer and start thinking like a mechanic.

Im using a brass punch to hit it, it just wont budge.

im going to get rid of the hemostats and stick a clothing hanger in there to support the valve instead so i can tap it all i want. A screw driver in my sparkplug hole aint working to well.

jagged edges should have less surface area, and flow better. Why waste time (time = money) making an oil feed groove pretty, when only the techs (or the mechanic, or the owner) will ever see it

[He Man]

whatever, i know what it is now, but it just looks like someone went in with a screw driver and hammer. Thats all im saying, it didnt make sense how it got there other then it was always there.

Anyway, i still have to get the damn closing shim to slide down. going to try it again today. I just wish the closing shim didnt hide the collets so well.

U have the mbp collets or the stock rings?

[He Man]

i have the MBP collets. I installed them onto one of the valves, and it was to tight. so i removed it and reinstalled the stock ones.  I dont have other shims to test which one would fit. And ontop of that, I did something stupid.

My hand slipped on the closing rocker arm ( im using a brass rod/punch to hold it down) and it pinned the stock collet into the shim and now it defintely wont drop. I called a few people to come give me a hand, and no the rare occasion i really need a hand, no one is available.

i need someone to support the valve with a thick rod so i can smack this stupid closing shim off and pry this stupid collet out.

Anyone have another way? if only my hand didnt slipp.

go get some forceps to hold the valve while you use both hands to do the work

[He Man]

If I tap the shim hard enough my  forceps just move around ( i have a pair they just arent shown). i need some solid pressure on the valve so i can tap if off...all while holding the closing arm down.

You should be able to insert an 8mm allen wrench, or similar, through the intake cover side and hold the closer away from the valve.

+1, it takes some finessing to get the wrench in the right place but once there it really simplifies the process

[sbrguy]

wow that sucks.. good luck with that.

i'll give you credit for trying all this stuff.

good thing for a lot of us to see this stuff you have going on.  it keeps people like nick at valley ducati and stu at flightcycles in business. those of us that prefer to leave this stuff up to the mechanics keep the independent mechanics and dealers in business.

That's a pretty nasty scar on that arm. I think you should get it welded up asap.
