Can any of you resident experts advise me as to the tricks involved with removing a stuck crank pulley on a 1994 940 Turbo?

I have searched here and asked Mr Google who referred me to an article suggesting the use of a 3 legged gear puller. The problem with that (my mechanic tells me) is that there is an outer and an inner component separated by a rubber cushion. Some special technique is therefore required to attach a puller to the inner part of the pulley.

Many thanks in anticipation for your help.

 

There are 3 tapped holes in the solid part of the pulley. You should use a harmonic balance puller which has the ability to allow you to insert 3 screws and by tightening the center bolt the pulley will come off. Your mechanic should know about this. If you use the 3 leg puller then you will remove the outer part of the wheel and destroy it.

 

Thanks for your thought. Unfortunately it looks like this.. no threaded holes? (Clickable Thumb).

 

Never seen that type but I would suspect there is a special puller made to fit into the slots . A 3 pawl puller would pull the outer balance weight off of the rubber isolator. How many slots do you have? You might want to try to heat up the balance wheel and hit it with a hammer. It is not a tight press fit but a key and sliding fit. You have a little rust holding it on. You may need to take a bearing puller and grind down the pawls to fit and lock into the slots. A good creative mechanic and come up with a way to get that off.

 

Usually the B230 does not need a puller--just some gentle tapping and the pulley comes off pretty easily... I'd soak it in some rust penetrating oil for a day, then see...

 

its an impact wrench or and impact ratchet. otherwise you need the special tool that ipd or fcp sells. I know that ipd has them on back order for a month or so. cause i needed to pull mine

 

Thanks for the thought. Soaking as I write. Good to know that it is not usually a major. A madly mechanically-minded friend said something similar but my mechanic gave up after an hour.

 

Thanks Jagtoes (a Jag next on my shopping list). My mechanic has already countenanced the idea of drilling and tapping and I said, "Not on your Nellie!" It is not an urgent fix as the timing belt has miles left in it.. it is just that I bought all new belts and covers on a shopping spree in the US (with the high postage rates it's wise to think ahead).

As my mechanic said drill I am thinking of putting a bolt through the hole and locking it with a nut and washer. The holes from memory are only about 1/4 inch and so I am not sure about the amount of purchase.

Being a born-again-motorcyclist but an old adherent to the Zen and Art of Motorcycle Maintenance philosophy I am looking for the perfect solution.. ("The Motorcycle you are working on is a motorcycle called yourself.") I think Beardog might have it.

 

Hey Beardog. I am a Kiwi but when i want a people taking back their power quote I always turn to Thomas Jefferson. Every government degenerates when trusted to the rulers of the people alone. The people themselves are its only safe depositories.

Thanks for joining the conversation. You are very much talking my language with your special tool reference.. although I think it is a conspiracy. Why couldn't they build them all in the manner Jagtoes described? May I ask what is IPD and FCP?

sorry they're all USA sites. fcp is east coast and ipd is west coast

here is the link for the tool I was refering to.
Crankshaft Pulley Holder Tool B230

The special tool fits into the the holes on the inner balance wheel and then locks it in place so that you can take a breaker bar and take off the bolt by hand.

I removed the balance 3 years ago to do the timing belt, but used a impact wrench. I had to pull the radiator to get room for the impact wrench. That's why I suggested the impact ratchet. This month the rubber let loose on the balance and threw the belts. I had to take it to the mechanic because the special part was on backorder for a month, and the strap wrenches I used didn't have enough grip to hold the balance in place while I pulled on the bolt with a breaker bar. So impact wrench and I dont have one of those at my disposal anymore.

Flying vee thats a nice quote, although it is missing a bit. I looked it up. Here is a more complete version of that quaote form the letter/speech jefferson gave.

"Every government degenerates when trusted to the rulers of the people alone. The people themselves are its only safe depositories. And to render even them safe, their minds must be improved to a certain degree. . . . An amendment to our constitution must here come in aid of the public education. The influence over government must be shared among all people. "


Jefferson was warning that a democracy could not endure unless the people were knowledgeable about the world and their gov't to a basic degree and that it should be the gov't responsibility to provide a basic level of education to its' people so that they may keep an eye on their gov't.

To bad the Gov't is cutting back on the education funds, of course the school gov'ts are mishandleing the funds they're given.

 

Thanks Beardog. Also for the new American connections. In NZ they would have charged me $US22 for an aftermarket front camshaft seal. I bought OEM (Elring Klinger) at Pelican Parts for $US3.50 (where the customer service lady is nothing short of an American Beauty). Shopping in the US is therefore a no-brainer.

I have just come from reading a bunch of posts about that tool bending and FCP Groton being very good about replacements.. and eventually a refund. The problem is that it isn't the part I am looking for. The bolt was a breeze to remove (I am told).. it is the crank-pulley itself which is proving stubborn.

The best I can come up with so far is using 3 bolts (inserted through the holes depicted) with nuts and washers to secure it. Just as part of my process I am wondering what the highly civilised Swedes had in mind when the pulley locks on..

Cool Beardog.. thanks for the addendum. So in touch am I with the machinations of Big Brother that I have a horrible feeling a mod is about to pounce with an off-topic reprimand.. Trusting in a little more forbearance in the land of the free you might be amused by the mushroom song.

Now everybody knows that engineers are lazy slobs
They dress in dirty T-shirts and complain about their jobs
But Management has found a way to make them toe the mark:
You feed them bits of bull****, and you keep them in the dark!
because they're..

Mushrooms, Mushrooms, keep them in the dark
Mushrooms, Mushrooms, I heard the boss remark
You feed them bits of bull**** til they can't take any more
When they stick their heads up cut them off and
ship them out the door

(You can substitute your own words for management and engineers).

I feel a Julian Assange/Hillary Clinton comment coming on.. but that's OK I managed to stifle it.

 

Well if thats the case. I would suggest several rounds of penetrating oil and a few healthy smacks with a dead blow hammer. and get that radiator out of the way so you can come at it with a good angle.

 

A "persuader" as they say. I will definitely be doing the penetrating oil thing.. reaching through the little holes in the pulley to run some in from the back even. Call me Pollyanna but I am still hoping for a diplomatic solution

 

Flying vee here is another U.S. presidential quote that should apply here.

'I have always been fond of the West African proverb: "Speak softly and carry a big stick; you will go far." '

Theodore Roosevelt

 

One other thing. Check with your customs people. There might be unexpected duties on automotive parts that will add to the total cost

 

Beardog yes I got hit with a big bill (15% GST) last time I bought in belts, front struts, all tie rods, boots and timing belt covers. When I had a friend send me a pair of motorcycle boots of similar value Customs contacted me regarding proof of purchase but then didn't impose the tax. It seems that there is a grey area when items are not sent directly.

I would have asked abovementioned LA-based friend to send on the big parts package but after he sat on my cam seals for 6 months I decided not to risk our friendship again.

The quiet voice big stick dichotomy is an interesting one to which I would like to give more thought For some reason I am reminded of the beast in Revelation 13:11, "..he had two horns like a lamb and he spake as a dragon." Who or whatever that beast is and no matter how lamblike, I am sure that somewhere down the line the "dragonspake" will come at the expense of constitutional freedoms and "In God we trust."

 

My understanding of Teddy the Bear :-) Roosevelt was that he was a bit of a character and that the West African origin was something that he just plucked out of the air. Shades of GWB's "fool me twice rendition," "There's an old saying in Tennessee.. I know it's in Texas.. probably in Tennessee.. "

The term "big stick diplomacy" was obviously taken from Roosevelt's West African proverb :-) More recently it has been used to describe the US response to 911. "Carrying" the big stick is one thing but in lashing out at an unseen enemy with it, many people have been denied their constitutional rights.. apropos your Benjamin Franklin quote.

Also on a US presidential note Harry Truman said, "The buck stops here." The US has so many big-hitters in their tool box-however that it is very easy to discount buck-stopping in favour of the most theatrical option available.

 

Well my crank pulley came loose in the end without too much fuss. I severally sprayed behind it with CRC, hot and cold trusting the heat would help it permeate.

Whereas my mechanic had suggested drilling holes so that he could use a puller I resisted. Being the good guy that he is he found another option. This involved removal of the splash tray which exposed the inner pulley from underneath. A couple of whacks of a screwdriver held against the pulley and there was immediate movement.

Breaking the job into bite-sized portions was the key. I will take it back for replacement of the timing belt and covers in due course.
