Timing On Rb20det

[Rancher]

Hi!

I'm putting my RB20DET together, and I'm about to do my timing. Ive heard of people talking about BTDC. My question is, are you talking about the harmonic balancer being 15 degrees BTDC? not have all the marks on the timing belt line up? I dont understand this. I dont really wanna get this wrong, I want the motor to go in shmic!

Please help!! Photos would really help if anyone could!

When putting the timing belt on, make sure all the marks line up. When you set the ignition timing with a timing light, set it at 15deg BTDC. If you are confusing cam timing and ignition timing i would recommend getting a mechanic or someone who knows to give you a hand at theis crucial stage.

yeah. set the cams wrong to the crank and you might as well drop a handfull of gravel into the motor.

if it is just the base time (motor is all together and running) then you just need a timing light.

can i come watch the gravel ?

When assembling an engine, everything is done with the crank, and hence the harmonic balancer, at TDC.

The only measurements that should be BTDC are ignition timing, which requires the engine to be running.

Ahh, just move the CAS to the right spot. now I have it. no gravel... And bugger the mechanic. I know what I'm doing.. just that part sorta stuck me. Thanks for the help!
