Sir Rupert Hobo

hey, i'm trying to piece a $200 POS together, but i'm gonna need some help.

i need to know the thread and pitch size of the following:

1. the three bolts and nuts that connect the hub to the rear end

2. the bolts that connect the pressure plate to the flywheel

3. the bolts that hold the seat rails down to the floor

thanks for any info.

this topic was just archived, like every bolt in the car is described

Sir Rupert Hobo

no, none of these are on there.

If you haven't got these by next Sunday, bump this or PM me... I'll be able to tell you at the very least 2 and 3, 1 if I figure out what bolts you're talking about.

Not gonna get around to doing that stuff until next week though... hopefully.

Sir Rupert Hobo

thanks bob

#1 is the part of the hub where the DTSS bushing is.

the seat bolts are pretty big, can make a guess m16s?

I too need the discription for the pressure plate to flywheel bolt. I couldn't find it in the fsm either.

Sir Rupert Hobo

kenteth, the four tranny mount bolts seem to be the same, but the seat bolts might be a little longer.

here is what it says in that archived thread..

Engine / Tranny Mounts:
(1) 14 mm head - Length = 145mm (5 5/8 in) (with head of bolt)135 mm (5 1/4 in) (from bottom of head of bolt to end of bolt). Nut on opposite end. FINE THREAD
(1) 14 mm head - Length = 100 mm (3 15/16 in) (with head of bolt) 90 mm (3 1/2 in) (from bottom of head of bolt to end of bolt). FINE THREAD
(2) 14 mm head - Length = 45 mm (1 3/4 in) (with head of bolt) 35 mm (1 3/8 in) (from bottom of head of bolt to end of bolt). FINE THREAD
(1) 14 mm head - Length = 40 mm (1 1/2 in) (with head of bolt) 30 mm (1 3/16 in) (from bottom of head of bolt to end of bolt). COURSE THREAD

where does it say the size of the TRANNY MOUNT bolt?

Kenteth

WTF is that, I thought the archived thread actually had the thread pitches. What a waste of an archived thread if it doesnt. Do s asearch in the 2nd gen forum (this one) for thread pitch and kenteteh and you'll find my bolt thread/pitch thread that actually lists the thread... https://www.rx7club.com/forum/showth...=1#post3932145

ok...

As above, FINE = Mxx1.25
COARSE = Mxx1.50

Hopefuly arron can verify and clear it up on the archived thread

EDIT: maybe he could correct the spelling of coarse too if thats all they are going to use to describe it :P

Kenteth

I'm going to run with m14x150 or m16x150... anyone able to elaborate?

Sir Rupert Hobo

yea, i'm really not getting that.

also, forget the hub nuts and bolts. i found those today. ha.. still REALLY need those flywheel bolts though..

Kenteth

I had to tap my flywheel before we installed it... it was some funky thread/pitch combo that we had to go to a rental shop and use one of the tools out of there 6000 piece tap/die set. Maybe m12x1. or 1.25... maybe it was m10 :P cant remembr

DubbayoC

just got some clutch cover bolts they are m8 1.0 fine thread.

Kenteth

I knew they were small rare bastards... didn't remember them being that small, but glad you found them

Sir Rupert Hobo

ok, seat bolts and hub bolts are taken care of.

i went to ace and they had none of the m8 1.0 fine thread.. where can i get these?

Kenteth

they are stupid rare bastards. If you have a NAPA go there, then check fastenall. If you don't have a fastenall, the NAPA store will tell you where you can check.

I once had to goto a Catipillar dealer once to get a FC3S bolt, so don't be suprised if you have to search for awhile...

DubbayoC

got mine at kragen. SHOUT OUT to the guys at kragen off taraval in S.F......nice guys.

Wankel7

Make sure on those pressure plate bolts you get some that are at least 8 or 10 grade.

James

Sir Rupert Hobo

well damn... alls i got around here is a napa. no kragens etc.

thanks for the advice guys. and i didnt know they had different grades...

Kenteth

yeah, its the type of alloy they make the bolt out of. We had to retap the flywheel because we used nice grade 8s that were the wrong pitch and after the first whole realised we were ******* it up A lighter grade would have screwed the bolt instead of the flywheel...
