[ANSWERED] Help with Bosch SR8581N Starter
I'm swapping my starter today and so far the job has been pretty straightforward. I'm trying to fit the new Bosch starter, and there's a boss on the block that's really in the way - it looks to me like that was the reason for the old design...to slip in on top of that boss.
Can someone who has ACTUALLY DONE this replacement provide some guidance here? I'm heading back out to try a few more things, but it's not obvious to me how it's going to fit.
THANKS!
[EDIT]: The solution is to loosen the dust shield on the trans housing - it's beefier than it looks, but once it's out of the way the starter slips right in. One frustration - the new, longer bolt is a different size...you'd think they could have made it 13mm like the original one...

I read a thread some time back that a forum member said he changed his starter without dropping the exhaust. He said it was tight and he had to wiggle it around until it dropped out. Do U think it is do-able without dropping exhaust? Thanks

Yes; the mounting boss is much stronger on the block side. That bigger boss was what gave me some fits until I loosened the dust shield.
I personally don't see how...but there are a lot of smart wrenches out there. I'd like to see some pics on how it was done.
It wasn't that big of a deal to drop the exhaust. The biggest need was just for a means to support, lower and raise the exhaust - I used a transmission jack. I hit all the bolts with PB, waited an hour, then pulled them all off with no issues. The oxy sensors were also a bit of a PITA, but no big deal. I was able to reuse the gaskets. Overall nothing difficult, just solid mechanics work.

tough working in that space. dropped the right header, but it won't go all the way down and can't lift it up and out either, so wrestling around it...did you have to grind anything?? thanks... Dave
