governor cup question for tra7

born2sled · Oct 9, 2009

here is a couple pics of my governor cup in the top part there looks to be something sheared off a bit of the metal its hard to explain where exactly but you can see in the pictures i also circled it with windows paint any way my question is do you think it will effect the performance of my clutch or do you think it will be ok

Are you running long pin weights? I assume it's in all 3 locations? If it's from the longer pin weights you have to run on higher clicker numbers (4+ usually, depending on the ramps) so they don't hit. Or get shorter pins.

i am not sure what it is from this is a used tra7 my other one was hooped so i took the one i got all apart and noticed those marks on the governor cup it is just on the one side dont know what it is from my main concern is do you think it is ok to use and will not screw up the performance of my sled

Looks OK to use from what I can see in the picture.

is that primary used? Are you the 2nd owner of that primary clutch?

That is not from long pinweights. Pinweight no matter what length will clear the governor cup at-that-location by 3 millimeters.
I have seen that "wear" before when tuners have used TShift levers and/or the TS large pin kit and install fasteners and/or large diameter thin tungsten washers trying to get heavy pinweight.

By a quick look at the governor cup, I can also tell you that your primary spring cover bushing is worn at or larger than the wear limit.

Those are stock arms and pins. Definitely replace the bushing; press in with a socket and use green loctite 609 (small amount around the race).

Have FUN!

You need a smal pick to get the circlip started.....one end has a "recess" to get a pick into, then get a little screwdriver or needle nose pliers to twist it out. I usually replace it with a new clip.

No, it comes out easy....just a punch around the edge and it will come out.
Use more care with the new bushing
