WTB 440 Crane Ductile Rocker Spacer

HeliPilot71 · Oct 26, 2017

Anybody have a hold down laying around? Picture of the exact part I am looking for. I am looking for the end hold down to utilize my Crane Ductile Rockers. Thanks for the help.

Grind the tab off and use it.....

Yup, you want to grind all the tabs off then use a shim between the holddown and the rocker to prevent wear and **** getting in the motor. If you need any with tabs ground off I have a full set. PM me

Center your rocker tips over the valve stems. Install pushrods and check clearance going down through the head. Sometimes you have to split the difference. Don't be in a hurry. Spacers and assorted shims needed. I bought mine from Summit and Crane.

I'm thinking .005 clearance between spacer and rocker. (Correct me on this spec.)

Why grind off the tabs if a shim is put between the tab and rocker?

How big is that tab ... a shim is only .030 thick.

The hold down tabs are too wide with those rockers.
