Correct Procedure for New Timing Belt Component Install

[06SubLegTx]

Hello,

 

I was wondering if there is a correct procedure or way to ensure both the Block and Head are correctly aligned to put on the timing belt. 

 

At this time the heads are on and not tension on any of the Valve Rockers.

 

The pistons are all in the Neutral Position (all in as far as they will go) The crank gear is aligned with Crank sensor, so I am sure it is off some degree?

 

Thanks for any help

There are all kinds of YouTube videos for timing belt changes. Just be sure to watch one for your generation of subie. Either that or use the link below and download the free FSM (factory service manual) and check the procedure. Takes about 10 minutes to download, and then see the engine section.

make sure to use the 'groove/dash line' on the tab at the rear of the crank sprocket. (align with the groove on that 'boss' above at approx. 12 o'clock.)

 

do not use any arrow or triangle on the front of the sprocket.

 

you can search for your engine to find the cam alignment positions. One may be tricky to hold in position but, if you align the crank firrst, all the pistons will be at mid-travel and valves will be safe if the cam slips.

 

also, find the tooth count for your engine. use it to triple check after you pull the tensioner pin and crank the sprocket thru 2 times to bring it back to the timing positions.

 

don't start the engine if the tooth count is wrong.

If the pistons are all the way down - turn the cams to their timing marks. Go slow and back off if you feel any abnormal resistance.

 

With the cams properly lined up - even the drivers side under tension - which tends to slip and "snap" out of alignment by 120 degrees or whatever it is - will not hit anything.  just move it back the same way it snapped.
