Title: Pushrods? Post by: deano on June 15, 2005, 07:51:09 AM 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? Title: Re: Pushrods?

Be careful with Red motors they have 3 different length pushrods so get the right length. Pushrods are not worth the effort for straightening!! Title: Re: Pushrods? Post by: ACE on June 15, 2005, 08:32:09 AM .....and grey motors have 2 different length pushrods ;)

I didn't know Grey's had 2 different length pushrods. Thanks ACE. Regards Aaron PS..... Why did they have 2 different lengths? I know Red's had different lengths for different block heights/Rocker gear (I think)? Title: Re: Pushrods? Post by: gp on June 15, 2005, 07:15:21 PM Don't know WHY they changed them, but the lifters are also 2 different depths. ???
Cheers, Graham Title: Re: Pushrods? Post by: julius on June 15, 2005, 10:17:11 PM The reason why is because they have 2 different depth cavitys for the pushrods to go into the lifters in the grey.

Cheers, Graham Title: Re: Pushrods? Post by: FCwagon on June 16, 2005, 07:50:28 PM 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. cheers, Leigh Title: Re: Pushrods? Post by: Tumbles on June 17, 2005, 09:25:15 AM I believe there are a couple of differn't width rods as well, are they relative to the length?
