Educate me on Pushrods

[rozemab]

Hello,

Getting my panhead read for the Spring and doing some preventive maintenance on her. When I started to adjust the solid lifter valves, I noticed this in the rear cylinder exhaust pushrod.

Obviously years of neglect caused the hardened end to become deformed. I plan on replacing all the push rods this Spring. My question is this: Researching replacement rods, I cannot seem to find the same configuration as I shown in the pictures. Both ends have a ball end, yet the pictures in catalogs really don't look the same. One end has a ball socket, the other end the adjuster with a longer 'nipple', so to speak.

I'm not sure what I'm suppose to order for replacements. The closest rod I could find is a Sifton setup in the JP cycle catalog. Is that a typical pus rod for a solid lifter conversion?

thanks , Brian

I just recently had the same broblem. I bought the Colony kit 7122-4. It has big ball ends, other bigger than another. I still had to have two of them shortened a little because I have two shorter Jim's tappets and two unknown brand tappets which are a little bit longer.

is it just me or does anyone else think that pushrod was installed upside down?

yep, there's a big ball end and a small ball end, there's a reason for that!

I was not sure about that after pulling the rod (ball size).

I thougth one was larger than the other but I was thinking the deformed ball gave it that look.

So, the larger ball goes into the tappet, correct?
And the rods are suppose to be different lengths. Do i simply pull one rod and find the rod with the ezact length or is there a more exact formula one must follow?

Is Colony the only choice I have for new push rods?

[Hog54]

The pushrods come in three lengths, the 2 shortest ones (equal) are the intakes, the medium one is rear exhaust and the long one is front exhaust.Ive had the same colony ones in my bike for 16 years,so I guess thier pretty good.

Folks,

Beware that the combinations of aftermarket recipes, as well as OEM, makes for many possibilities of mis-match, in addition to upside-down installations.

My wife has reassured me countless times that I am not qualified to comment.
Nor am I qualified with the telephone question, for when I dial, it goes "swish-clunk,..tic tic tic tic tic" with each digit I enter.

But it always works, the battery never goes dead, still works when the power goes out, and I honestly can hear better upon it, with my good ear anyway.

cotten,

i hear ya!

what the heck is up with the digital age?

i swear i could hear better on an old fashioned western electric hand set.

on a side note, i have a authentic candle stick phone in my bar. my grandaughter is the only one who answers it.

when she hangs up she kisses the ear piece... go figure!

I used Sifton oversize hydraulics in my 1965 Glide, and Comp Cams pushrods. Seems to be a good combo so far. Mike

of all the combinations in Cotten's assortment the only "fool proof" one is the set on the far left, the lifter is the one that the MoCo used for the hydraulic pushrods, the original push rod was installed with the "oil can" up. Best bet for those was to throw the push rods in the junk drawer and install a set of Colony solid rods, but save the original hydraulic push rods so you have a fool proof refernece to tell you which end is up.

been there, done that....

Homebox I got the bike from wants me to work on the bike at the shop, which I prefer right now anyways.
But pushrod adjustments are something I have been wanting to get around to. Along with the pushrods I thunk I would look into timing all at the same time.
When I turn the bike over I can hear a 'tapping' noise I guess in the rocker covers. To me it sounds like somethings loose, pushrods possibly. In doing this it wouldnt be a bad idea to take the heads off and take a good look see in my valve train, reseat. Would doing all this at the same time be to my advantage?
