clutch pressure plate torques

[dougyfresh]

I'm in the middle of putting my engine/trans back together and getting it in my car today.

Flywheel is bolted on. For my 22.5mm OEM Bolts my torque was 60Nm + 90deg

What are the pressure plate bolt torque values? Shall I put some blue loctite on the threads? Looks like the ones that came out did not have any loctite.


FYI: Southbend OFE SS clutch with OEM DM Flywheel. Clutch has been installed before so I'm just reinstalling everything. New flywheel bolts and re-using PP bolts.


Thanks!

60nm + 90 degree turn

i thought the flywheel was 60nm + 180 turn?

yeah i just checked the bentley.. flywheel is 60nm + 180 and the pressure plate is 60nm + 90


i have the pic but i cant figure out how to load it... i can email you the microsoft word file if u want

Jake told me the spec for the PP bolts is 22Nm. He suggested (and I did) 30Nm with loctite on the PP bolts. That is what I did and it felt pretty friggn' tight. I don't see 60Nm on the PP bolts.

Trans is now on and everything looks good.

Engine/Trans is going into the Avant shortly....

i would agree with that, i did the 60nm plus a 1/4 turn is all i could get , i started to strip one and said the hell with it, thats tight enough... i have the snappy torque wrench so it clicks when its at 60nm

The Craftsman one I'm using clicks too. I used a 1/2" breaker bar to get the 90deg turn on the flywheel bolts.

[Papachristou]

be a man! do 60nm + 180!!!!!!

I also did EXACTLY what papachristou did:

60Nm + 180* for the Flywheel (New OEM bolts - supposedly have loctite already on them)

60Nm + 90* for the Pressure plate bolts (I used ACE hardware bolts grade 10.9 versus the OEM bolts that are grade 8.8...plus they had a 13mm head versus the CRAPPY OEM hex head bolts....I did NOT use loctite)

[Papachristou]

oh i hated those OEM pressure plate bolts, so soft... i dread if i ever have to take them out... ill probably be dremeling a cut in them to use a large flathead or something... i should have done what you did... oh well, hindsight is 20/20

60Nm for the pressure plate is too much! They are a 6mm bolt which can't take too much load. All the torque on the pressure plate is taken out on the dowels.

I had no problems with the OEM flywheel bolts (12point). No stripping when removing and no issues when installing. It helps to have the right tools.

oh yeah definitely, the OEM flywheel bolts (spline drive/triple squares) are a great design and allow you to put plenty of torque down.. i was talking about the pressure plate bolts.. shitty design... i was just following the bentley torque specs for them......
(i can assure you, i have all the right tools!)

60nm+90 is too much for those soft allen head pressure plate bolts

My impact gun does great things

Makes it easy when u dont have big guns

+1 ... I too was referring to the PP bolts. I had ZERO problem installing the flywheel bolts.

I have all the right tools and the some! When I first installed the PP bolts I used brand new OEM bolts and all they did was strip the damn head and then I had to dremel a big notch in it and it took like 30 minutes to get it out with a big flathead! But with those ACE hardware bolts everything went super smooth

im sure thats what ill be doing if i ever do another clutch job... if i do, im going to go to a lightweight flywheel.. .my car isnt a DD anymore so i can mod all i wont now

i really think if i had the new flywheel there (and all the stupid new bolts), i could do the whole job in 8-12 hours now..

i meant 30 ft. lbs. doug lol... whatever, i explained to you what those bolts do so its all good , the loctite is what matters

That is what I did, look at post 4.

[317ssayzarc]

post 4 says newton meters....

look what i got today...



means its go time...

Awesome!

I just finished wiring my EBC and boost gauge. FMIC should be here tomorrow.
