Timing Belt Guide (MT only?)

ellarsee · 03-12-2018, 02:08 AM

I'm in the process of replacing the (dead) Phase II EJ22 in my 2000 Outback Sport with one from a 99 Legacy. It seems that both of the motors were originally from automatic transmission cars because neither of them have the timing belt guide. I've got a printout of a PDF manual which lists a drawing of it as S2M0294 in section 2-3 [W2A2].

I am going to make the assumption that this part isn't terribly necessary, but why would it be on manual transmission cars but not automatic transmission cars?

I'd venture that automatics can't suddenly unload the transmission like a clutch can, so it has to be there to help prevent the belt from slapping around and losing timing.

Agreed. All the Subaru timing belts I have done have the guide on MT's and don't on AT's.
It wouldn't hurt to have it on an AT, I would make sure it was there on an MT. Thus, if you put an AT engine in an MT car, I would make sure the guide is there.

Yes, manual models only. Automatics dont engine brake like having a completely locked clutch in a manual box.

I don't suppose that there is anyone anywhere close to Santa Cruz CA that has a spare they are willing to sell cheaply, or for that matter can mail it?

It's too late to call the dealer.

Junk yard/pick and pull?
Bring a chain wrench, 1/2" breaker bar and some sockets.

Need it like today? yeah, maybe try locals on FB subie group(s), i-club's NorCal section, or junk yard. Perhaps a southbay shop might have one laying around.

Or if you wait a few days, ebay has many right now... just source some M6 or 8 hex-head bolts. Or aftermarket (IAG, tomei or cusco?) and overnight shpg.

I ended up ordering one from the dealer today. It'll be in on Thursday, I spent today cleaning my shop, I'll be working 2 hours away tomorrow and Thursday.

Your oil pump has bolt holes for one right? Some automatics didn't even have the threaded holes to mount one.

I can dig around my pile of crap and see if I have one to use. That is, if you want a used pump, or to have an example of where exactly the holes are
