Interesting info, thanks for posting. It should be noted that only manual trans Subaru engines came with that guide.

None of my EJ engines have that belt guide, not even my JDM EJ20G came with it, and that engine was mated to a 5MT. My understanding is that it was for manual transaxle cars only, and the problem it solves was the belt slipping off when the trans was left in gear for the boat ride over. The back and forth rocking would cause the belt to skip a tooth. My EJ20G has a redline of 7400 RPM and it's fine without the guide.

So I guess you could leave it on and space it off with the special tool. Or if you aren't planning any long boat rides just remove the guide altogether.

I did my adjustment with the engine on the stand after rebuild and verified it after tightening the bolts. I do like that gauge plate they made to set the gap.

I believe the purpose of the plate was for miss-shifts as it is only on manual transmission engines. So if hot rod guy missed his 1st to 2nd shift it would keep the timing belt in place before the rev limiter kicked in.

That more a case of: not changing the idlers and tensioner wile doing the belt. Idler/gear, tensioner have a life span. New tensioner need to be carefully check, this one was new:

I don't use that guide:

Hey scott,

Here is what i did so i did not have to take everything apart. Remove the front pulley
find something about 3 inches in diameter trace a nice circle and use a dremmel to cut out a nice circle around the interior crank pulley, be careful not to go deep. Then remove the guide, the bigger hole will be covered by the pulley.

the guide mentioned here is made to keep the manual transmission cars from jumping time when shutting off,NOT just for shipping.as a subaru tech i have seen many a manual trans outback jump time when this was left off...you can set them at the spot with the most space possible between them and the timing belt and they work great,no need to measure.

While not trying to question a real suby tech, I can tell you my guide was at the highest point and I was getting some significant discoloration right where it would touch, even thou I could rotate the engine and it had clearance. So it was obviously touch at some point when running.

My question is, is,it normal to see wear on theses, even when adjusted correctly?
Thanks
Todd

It's super easy to adjust on a stand, but in the car you might need a mirror to adjust it.

I haven't sen any problems with leaving it off. Most of the motors come from auto cars so they don't even have it. Never seen a problem on any conversions.

Kind of seems like it's just better to leave it off. Just make sure your tensioner is in good shape.

Seems like the easiest thing for those of us with the guide installed is to pull the right hand TB inspection cover and check the back of the belt for unusual wear patterns. I installed mine on the stand with careful spacers installed (I used drill bits of appropriate thickness as shims).
