Beehive Valve Spring Retainer Heights

FSA1673 · 07-11-2013, 10:11 AM

Old tool steel retainers are 10 degree standard locks. New beehive retainers are 7 degree standard locks. There is over 0.100 in the difference from the macined spring pad to the underside of the retainer. The beehive retainer is lower.

I talked to PAC yesterday an they said their lightweight tool steel retainer for the beehive installs approximately 0.100 higher than the standard chromoly retainer. He told me to use R643 for the retainer on the 1409 spring. PAC also told me I would need to buy mini 8 locks to go with the new retainer and that should give me enough room. The trouble is the innner diameter of the 1409 spring is 0.650 and the outer diameter of the inner ring for the retainer is 0.658 according to their catalog. Which should not work.

I will have to call them back to today and make sure it is not the R633 retainer I need.

Thanks for all the help.
