Any ideas where to fix this saab tool?

Need to remove the cranshaft pulley bolt from an engine and gearbox (still joined together) that is out of the car.

Clutch and slave cylinder removed, but the only possible place that I can see to fit the tool is about at the 3 o'clock position (below the starter motor)where a large bolt goes theough the casing that holds a leg from the underside of the trottle body to the casing.

The only thing strange here is that the bolt has a larger diametre than the fixing hole on the flywheel lock tool and wont thread pass through.

Thanks

NO need to undo crank pulley if this is just for the seperation you are doing .

You can usually lock up the flyweel using a socket on one of the bolts , turning crank slightly to lock it in the hole the socket passed thru ,
Or you can use a screwdriver against the ringgear on the flywheel .
Is it the flyweel you are trying to remove ? or the crank pulley ?
Havent seen the SAAB tool , so unsure how you bolt it up . But guessing it would be one of the starter mount holes

Here are a few photos of the Saab Flywheel Locking tool. The teeth are about 2 inches in length, fairly small tool...

Aussie900, you are correct about not needing to remove the crank pulley bolt for the trans swap, but once the engine and gearbox is out of the car I was going to have the crank pulley bolt loosened. This should allow me at a later date to get at the timing chain cover just to see why and maybe replace the chain components that have worn so quickly. I figured that it would easier to remove the bolt whilst the engine and gearbox where still joined and that I had the use of a garage mechanics with all the tools.

I hope this makes sense, what do you think? Would like to use the flywheel tool to lossen the crank pulley bolt.

Struggling to picture your suggestion about using a socket on one of the flywheel bolts

There's two places I fit mine. One towards the top of the flywheel, near where the TDC mark is, and one in the gearbox housing, drivers' side (US), there's a small window in the casting.
Nutcase,

This is all new to me ......

The tool has only one hole to put a bolt through. Would the tool have to rest against part of the casing wall to stop it pivoting when the flywheel moves?

Would it be important for the hole in the casing to be of the same diametre as the hole in the tool. ie to stop the tool wobbling when bolted up.

I hope this makes sense

Is the flywheel locking tool available from suppliers otherthan Saab stealerships. If so where?
.... Only Saab Dealerships

Still trying to figure out where to place it, hopefully Nutcase will reply as Shan's picture is identical to Bentley's picture but does not resemble my 16V non turbo flywheel.

No. If you consider the radius of the flywheel and compare it with the radius of the tool, you'll see that the tool rotating would turn it sideways very quickly and would force the teeth down into the edge of the flywheel. Since the flywheel is hard, this cannot happen so the flywheel cannot rotate.

The lump welded to the back of it rests against part of the gearbox - that was never an original method IIRC, but a later addition at the suggestion of a dealership. Using it at the top, the tool rotates round the bolt a little bit and then locks. I think the hole in the tool is a couple of millimetres oversize for an 8mm bolt.

There is a place on ebay usa that sells the tool for more than I paid for mine through saab.

Quick update and thanks for all the responses...

The tool is placed at the 11 O'clock poistion above the flywheel, by removing the bolt in the casing and replacing it with a slightly longer bolt.

Worth its weight in gold as the crank pulley bolt came off with just a breaker bar in seconds.

I thought I had one of those genuine Saab tools, but I can't find it and only have an aftermarket tool that is being annoying to use. I can bolt it to the engine just fine in my 81 turbo car, but it won't stop turning when I apply a lot of force to the crank pulley nut and I don't want to tighten the bolt (using a longer one) too much in case I strip the thread in the block. Might have to go with the 'bump the starter' method if I can work out a place to put the handle of my breaker bar (similar to what I did recently when renewing the crank pulley on my 9000).

Is the torque of the crank pulley nut meant to be 150+ ft/lb like it is with a B202 engine? Going to be fun tightening it back up after replacing the leaking crankshaft seal. :cool:

The tool I have is one of these:

For those of you who've tried the screwdriver method, can you describe where to place it or better yet show a pic (or several) of how you have used a screwdriver to lock the flywheel (or auto trans driveplate in my car's case) against movement?

The only tool that works is the one pictured near the top of the thread. I eventually found mine after trying one of those cheap ones with a big slot and used the proper one with success on the black 2.1 car job. It works because when it bolts to the engine it will self-lock against the flywheel when the pulley nut is turned and the engine rotates slightly to bind onto the teeth of the tool.

There used to be an aftermarket supplier making them (copied from the genuine Saab tool).

In addition to that, I found a thread from about 2 yrs ago (2013) on saabrally.com about one of the members there making a run of flywheel locking tools copied off an original. http://www.saabrally.com/forums/viewtopic.php?f=11&t=3513

I located the pics of the flywheel locking tool installed on the B212 engine I've been working on over the last few yrs. The only hassle with using it is that the plastic cover over the flywheel needs to be moved out of the way, and that's a bit of a PITA at times but at least being plastic it's flexible and bends/twists around things.

Hope this is helpful.

I'm currently trying to find my genuine flywheel lock tool but have just today found an aftermarket one that I know I tried when doing the CPS work on another 2.1 car but found difficult to use.

I always had all the SAAB Special Tools available because they were shipped to the Dealers automatically. Most were quite useful, some necessary.
I never found any use for the flywheel locking tool.
