Pushrod ground up

[MS-Geek]

Hey all,

Wondering if anyone ever ran into this. I haven't had my Pan long it's a 48. When I first got it I found one of the tappet blocks was broken up in the case, one of the tabs broke off and was chewed up. I replaced them and cleaned up any loose metal, didn't look like it caused any other damage. The other day I noticed a rattle in my front rocker box. I opened it and found the front pushrod was loose, it came right out without loosening the adjustments.

I found that the nipple on top of the pushrod was worn away and there was fine ground alluminum on top of the heads, shiny sheen to the oil so it's spread there too. I plan to flush it as best I can and replace them. Haven't got into the cam cover yet but will clean that out too.

Has anyone ever seen this?

thanks,

..Has anyone ever seen this?..

MS-GEEK!

Not 'til you post a pic or two.

Use the macro mode on your camera, where a little tulip icon appears,
and then edit your pics down to size before uploading.

Wonder what all that metal is doing downstream.

I already cleaned up the filed metal but here's the picture of the pushrods, they should both have the nipple right?

Dear, dear MS-Geek,..

Even the one on the left is enormously tortured.

The right is unboleeveable.

Wonder where that metal went.

I have a shoe-box full of those COLONY pushers!---They all look like that or they fragment where the ADJ> is or the BALL on top!---THE ADJ> & TOP are olny a press-fit in the tubes!,& to add they only go in a mere 1/2 inch(this is the biz-end on the rods you would think they would go atleast 11/2 for stability! COLONYS are known for this,even if set right sooner or later they FRAGMENT & you end-up with additional damage if 1 was to go to the right spot!-IF pics. are needed I will post them!--But im sure alot of you just saw what they do!,NOW in this situation that MS GEEK has I would pull the tins & check the rocker-arms--I would bet there is damage there! That 1 thats almost flat took some time doin!(steels are best for a pan!)After my first frag. loong-time ago, never ran alum. again & therefore am happy!--Id like to add that last year I changed-out a set for a Bro,& nothing has changed as far as adding some more meat to the upper & lower ends of them.still a 1/2 inch but with 2-flats that do 2-things you can get a wrench on the tube & it CRIMPED the inserts!-NO CHANGE STILL JUNK!------RICHIE

Richie
What steels do you recommend?
I have home made steel pushrods with Colony ends.
It's ok right now.

Folks,

I ran "solid" pushrods with aluminum ends for years without a problem.

The only cause I can dream up for such wear upon steel is loose adjustment.

Thanks Richie, Can you post pics if you have of what damage to look for in the rocker arms?

I was about to order new colony pushrods, glad I didn't yet. Will look for others.

I use Comp Cam pushrods in my hydraulic '65. A little more money, but worth it to me. Mike

Did anyone else notice one is a larger
diameter than the other? The solids in put
in mine from colony came with a set of
aluminum pushrods. While turning the engine
thru to adjust the pushrods, they were "clicking"
at the rockers. The flat on the top of the
ball end was catching in the oil hole in the rockers.

I put the original pushrods back in. I would
like to replace them with new steel original
type pushrods but haven't found a source for them.

The original ones had light traces of scoring on the
ball that i polished out but they should be
replaced. The colony pushrods would just wreck
things, maybe someone has had good luck
with them but i think they are junk.

Geek,
They're aluminum also.

Yeah, I thought since it had steel tips it may be a little better. I don't see many options other than converting to hydraulic

Never had a problem with colony pushrods.And the ones that are in my bike look brand new after 16 years.But I do have hydraulics.

S&S has steel, non adjustable push rods for solid lifters. look under products>vintage>1936-1984 big twins. Scott
