Today I got a friction spring, friction nut and plastic cap for the rear bank of the type-r.

I was worried that the epc has 3 different codes for the friction spring, and wasn't sure which I needed.

But, I just quoted the standard part number and they seemed to find what I needed.

The ones I received have the indents in the spring, and cut outs in the nut, so i it shouldn't really loosen up as much in the future.

I'll post the part numbers I used in here shortly

Matt

Nice one Matt


Mark

the part numbers i ordered are the following:

KLY1-12-417A = Friction Spring

KL01-12-412A = Lock Nut

KL01-12-603A = Oil Seal Cap

Matt

The three parts that are needed:

KLY112417A
KL0112603A
KL0112412A

This is the updated friction spring and nut compared to the old style. I had a cut out on the nut, and 2 extrusion on the inside of the spring, so it doesn't spring.

Torque spec for the lock-nut is 55-61 ft-lbs or 74-83 Nm

[b]Camshaft Installation[/b]

1. Apply clean engine oil to the camshaft journals, camshaft lobes, and camshaft gears.
2. Install the camshafts so that the intake camshaft gear mark and exhaust camshaft gear mark align. Adjust the friction gear position with a screwdriver so that the HLAs are not lifted by the cam lobes. (Intake side cam lobes of the No.1 cylinder (RH) and No.2 cylinder (LH) face straight up.)

3. Install the thrust caps onto the cylinder head. Hand tighten the cap bolts gradually in 5 or 6 steps in the order shown, until the thrust caps are fully seated on the cylinder head.

CAUTION:



Install the thrust caps (5 mark on RH, B mark on LH) first. Otherwise, camshaft can be broken or damaged.
4. Apply silicone sealant to the shaded areas as shown.

CAUTION:



Because there is little camshaft thrust clearance, the camshaft must be held horizontally while it is installed. Otherwise, excessive force will be applied to the thrust area, causing burr on the thrust receiving area of the cylinder head journal. To avoid this, the following procedure must be observed.

5. Install the camshaft caps according to their identification marks, and hand tighten the bolts.
NOTE:



RH: numbers
LH: letters
6. Tighten the bolts in the order shown. Verify that the camshaft remains horizontal as the camshaft cap bolts (marked 1 in the figure) are tightened.

Tightening torque

11.3--14.2 N·m {115--145 kgf·cm, 100--125 in·lbf}
7. Tighten the bolts again in the order shown.


Tightening torque

11.3--14.2 N·m {115--145 kgf·cm, 100--125 in·lbf}
8. Apply clean engine oil to the lip of the new camshaft oil seal.
9. Push in the oil seal slightly by hand.
10. Tap in the camshaft oil seal evenly with the SST and a hammer

Cheers Matt.

There's a friction ring replacement guide at www.club323f.com too

Can you tell us what sort of noise it was that caused you to know to change this friction spring?? And what revs it came at?

Can you please link me to the site where you bought the friction rings ? Or at least tell me what you searched from. I need shipment to Romania

This is great thanks !
