Cam Belt Tension On Rb26/rb30

[leeroy_25]

I Just fitted my cam belt on my RB30/RB26 build.. How can I check the tension on it? I am running an idler at the bottom and a tensioner at the top using the dayco belt. Fitted a treat! I have not got the spring on the tensioner as there is no where to locate it. I presume this is normal practice? Can I tension it using a torque wrench in the hex tension hole? If so what torque setting do I need and then how can I give a manual check on the belt? I.e by how much twist should it have and on which area of the belt.

Thank you

im not sure if the tension on an rb30 is the same but id imagine it is

crank it over by hand with the top tensioner loosened of and the lower tensioner tighened up to the position you want it in,

crank over 2-3 times so that the exaust side is tensioned and the slack is on the inlet side.

the r32gtr workshop manual says the following

" - Insert the hexagonal wrench into the hexagonal hole. While holding it by hand so that the tensioner does not move, tighten the tensioner securing nut to specified tightening torque.

Tightening torque - 43 - 58 NM (4.4 - 5.9 kg-m, 32 - 43 ft-lb)

- The initial tension on the belt should be 196N (20kg, 44lb) in this condition"

id say from reading this that the belt tension should be 196N, done through the hex socket and that the tension on the securing nut should be 43 - 58NM. Id have to grab a torque wrench from my mates place to be sure though to see if it feels right be hand

anyway hope that helps Lee
