Hi Everyone,

 

Any suggestions on how I can check push rods for straightness?

Spin them slowly in a lathe and clock them with a gauge.

 

A bent push rod should be replaced and only straightened in an emergency to "get you home" .

I just spin them in my fingers and you can see it.

 

Or, put one end on a table and do the same (between the fingers on the other end).

 

When they bend, they really bend !

You'd have to go outside the elastic limit to bend one permanently and that will be pretty obvious.

Guys,

You are incredible. Since I have no lathe, I will try the method suggested by Moke Spider. What I'm concerned about is not so much bending in use but in storage. Back in the day I used to race a Mk1 Fiesta with a Kent 1150 cc engine, which is quite similar to the A-series and with a minimum budget and lots of used and abused spares avaiöable, selecting the right parts was the recipe for reliability.

Cheers

Just roll them on a flat surface.
They are rarely ‘slightly’ bent - they’re either OK or it’s obvious

Then don't store them in a flimsy box on the floor where you will tread on them.

 

 

If you are just going to 'roll them', do it on a horizontal mirror and get your eye down as close as you can to mirror level.
