PS spool valve insertion direction ????

[Devildog]

Have not been on here for a while hope all are doing well.  A few weeks ago my Bendix Power Steering was leaking at the control valve, we cleaned and installed the two new lip seals. It lacked worse than before new seals. Another guy was helping and did not pay attention to which end was which on the spool valve as he pulled it out. i have replaced two of these on my friends car with full success, re-inserted same end as when came out.

The instruction say to re-insert the same direction. I measure the dimensions and no difference. However, on the pic attached there are detailed machined groves point by the knife blade.

Anyone know which end goes in first ????? groves or smooth end first.  If you know you will be a Master Avanti parts trivia contestant.

 

many thanks

Do not recall spool orientation. However,  make sure the lips ln the seals point in bound - toward each other. Otherwise,  it leaks.

Yes, an old mechanic gave me his lip- seal tool to get the lip tucked in without damaging the seal.

 

thanks

The grooves go toward the rear of the car, or cap end of the valve assembly.

thanks Brad.

I installed new lips seals with PLENTY of lubricant and seems to be sealed and working properly. I inspected the removed lower (rear) lip seal, I guess I just damaged the edge when I installed it TOO dry.

 

Thanks all

Joe

Hi Joe, please remember this rule. ALL seals must be lubricated. Thanks JohnB.
