Hellow, newby here. I have been comeing here for a while but have not posted until now.

I just finished a 56 F750 that I made into a ramp truck.
All was well until I started to drive it. It has had a lazy life, not being run since 2001. With only 15,000 actual miles on it, it decided to bend a push rod.

I r&r the rocker shafts and cleaned them. I have oil comeing up to them but I am in need of a push rod that I can't seem to find.

The parts stores that know what a 302 Y block is, show a 9 & 9/16" push rod.
Mine is 9 & 13/16" long.
The problem may be that I'm not sure if I actually have a 302.
The casting # is EOS 6015. I'm told that it is proably ECS 6015.
The truck was origionaly an Americian LaFrance fire truck.

Is there anyone that can help me out of this delima?

One man in Ca. that I contacted had extra pushrods for his 302 but they were 9 & 9/16'.

Would anyone who has any like to sell me one or two? I sure would apprecieate it.

Push rods for the regular light duty Y block measure 8 1/8" so I would guess you have the 302.
And BTW, most important, welcome to the forum.

 

I am going to ask a dumb question. Did u measure just the one pushrod?
I know nothing about this motor, but from reading this, it made me ask..

I just had a funny feeling about it when you said your is a 1/4" longer than what two different resources call out.
Someone didn't put an oddball pushrod in, just to get it down the road?

Just a thought. Welcome to my second home!

 

Welcome to the forum, Roger. I am by no means an expert, but if the engine in your truck is the original engine and in fact a "Y" block, I would think it would be a 292 or a 312 cubic in. engine. The 302 is a different animal. Someone with more knowledge hopefully will chime in and give you a good answer. Good to have you on board, good luck with your project.

Y-blocks for heavier trucks included the 302. Not at all related to the small block 302 that was to come later.

 

There are a bunch of Y blocks in this family, being 317 302 332 & 368. Do you
have little buttons on the top of the valve stems which are rotators?
It just depends if it does or does not. Who knows even in its early life
they put a 317 in it. Proof- we had a new C950 with a 534cid volunteer
firemen are not truck drivers and down shifted into 2nd instead of 4th and
just about put a piston though the seat. They couldnt get a 534 so they
settled for a new 401. I mean to visually look at them they are identical,
except inside. A 56 750 should have a 302 but could be upgraded with
a 332. I know this cause I have a genuine 332 and in routine mantanace
to clean rocker arms etc I lost some little buttons, assembled it
hard to adjust rocker clearance ran terrible. Inspected, gave a good look,
looked like some pushrods got shorter. Went to the book, took it apart, come
to find out I blew half of them away with the air gun. Good thing I had a
parts motor. Missing this tiny button causes a different lengh in pushrods.
Most people never seen these, not in the small Ys not in FEs only typical
with big block Ys. |Again who knows I rember common practice to replace
with a 368 from a 57 Merc. looks the same but these Turnpike engines
didnt use rotators usually reserved for HD truck engines. sam

 

I think that i may have solved the problem.
I measured the total lenght of the pushrod and not the "working length" at the bottom of the cupped end.

I believe that is where the 1/4" difference is. I will order the 9 & 9/16" rods and compare them.

Thank you for all the comments, this is a very friendly site indeed!

Roger.

Thanks for the education on "Y" blocks, (I know next to nothing about large trucks). All my experience has been with car and light truck engines. Was working with my brother last week trying to find a T-Bird 312 for his '56 Fairlane Town Sedan. That's what I like about this forum, make a (dumb) statement and you are sure to get educated quickly. I am still impressed by how much I don't know.

Gil

 

I think we've all done that.

 

I finally located a source for pushrods listed for the 302.
They arrived and they are 1/4" shorter than the ones in the engine.

The ex valves have the rotaters on them that Big Job mentioned earler.
I installed the shorter push rods and there was enough adjustment to adjust them but they are on an a slightly different angle then the others. I hope it wont cause a problem.

I would still like to get the correct ones. The overall length is 9 and 13/16"

Roger.
