Pushrods?

[deano]

Hi Guys,
Thanks for the help with the rocker removal removed the pushrods from my 138grey and found that 4 are slightly bent, can I still source new ones or can I staighten them myself?

If you have a Grey engine second hand pushrods will be the go.

Be careful with Red motors they have 3 different length pushrods so get the right length.

Pushrods are not worth the effort for straightening!!

.....and grey motors have 2 different length pushrods

I didn't know Grey's had 2 different length pushrods.
Thanks ACE.

PS..... Why did they have 2 different lengths? I know Red's had different lengths for different block heights/Rocker gear (I think)?

Don't know WHY they changed them, but the lifters are also 2 different depths.

The reason why is because they have 2 different depth cavitys for the pushrods to go into the lifters in the grey.

Pushrods are easily straightend as my previous motor bent 2 and I successfully straightend them in a vice with soft jaws and a hammer. Worked fine for 6 years until the engine was rebuilt.

Grey's have 2 different lengths because the early engines did not have a drain hole in the cam follower and oil that sat in them sludged up easily and also couldn't drain out at oil change intervals. All up they hold about 1/2 pint.
Straightening pushrods is a temporary fix unless they are done perfectly. Because they're expected to rotate in operation.

I believe there are a couple of differn't width rods as well, are they relative to the length?
