YES

first time I realize 79/80 irons (r5) use 18 tension bolts and 81/85 irons (y) use only 17.

CRAP

I ported a center iron, took me a lot of hours and now I cant use it...

 

No good man. Thats all I can say really, sorry...

 

you'll remember to check next time?

 

thats a mistake that wont be made twice. sell the iron or get the correct center iron and try again...

 

I probably have one you need.

 

Im hitting a shop here this week to see if I can trade mine.

I have a R5 iron, but has surface pitting and Im not sure if it goes beyond what lapping can fix

 

I have a lapped R5 just sitting here. Want to send me a PM?

 

I aprecciate the offer, but shipping and customs would kill me on one of those

 

ok, good luck.

Have you read my recent thread about why it's not such a good idea to lap?

You might be better off cleaning the rust and usng the plate. Minor pitting is ok because as the side seals pass by, there is very little time for copression to be lost.

Anoter option is to cut some NPT thread in the rear plate tension bolt hole and install a pipe plug. I had to do that on an R5 with all 19 tension bolt holes when I used a set of GSL-SE rotor housings which lack one tension bolt because of the oil injectors. The NPT plug seemed to work great.

 

I read about it, I already knew about the nitriding on the plates.

If I take pics of the plate would you mind to chime in?

Im afraid corner seals and side seals migh get caught in the pitting and tear apart.

Also, not sure if it might be inside the oil control rings path.

 

Go ahead.
