Hi all

I need to remove the bimetallic strip per Wally Plumley proceedure. However im not which part im supposed to remove. The thin strip is held into the brass colored metal bracket by four tabs in slots. How do i remove this so i can refill my unit with out doing damage to the strip.

Thanks John

I got that last issue of the 928 catalog and i am still not sure how to do this, or where to get the Toyota (dealer perhaps0 repalcement fuild. John, dude, you are pretty brave.

Can you post the the step by step on this that Wally Plumley gave you?

Go to my website, pages 11-13. I have step by step pictures and links for the sites that have the write up of the repair. You may have the clutch that wally describes in his procedure. One small note though and i didnt mention this on my site. It took 3 hrs to fill the clutch drip by drip. I had to constantly do the heating and cooling cycles over and over again. Very tedious. Thats why i did it in my home office while watching TV
(Speedvision of course!)]

My temp was rising at idle. It was ok as long as i didnt sit longer than 5 minutes and got moving again. If i was in a traffic jam, its was bad.

I mentioned it on my timing belt page, but the clutch rehab didnt make a difference. However that's not to say it did'nt work. I may have another problem. Before i spend 300 bucks on a new fan clutch, im going to R&R the thermostat. I noticed odd things about it too. Like it took forever to open up. I think
it may be sticky. Its only 25 bucks and I was going to flush and refill my coolant anyway with the Autobahn blue stuff i bought 6 weeks ago. If that dont fix it. I'll get the new clutch.

Just finished the clutch fan refill as so eloquently descibed above at John's website. Temp guage was creeping up at stop lights. With the engine off and warm, the fan would turn 5-6 times with a flick of the wrist. Two bottles of liquid gold ($18.00 for two 18ml/cc bottles) that I put in by using a standard plastic 10ml/cc syringe, fixed the problem. I put the fan/bracket in my bench vise and spun the fan will injecting 6ml/cc at a time, Took about 4-5 minutes. The fan was still warm from driving 10 miles home from work. The syringe bore fit perfectly in the hole and the whole job took less than 20 minutes.
Thanks for the good info!

John,
It seems there are two bimetallic set ups - one as Wally describes, and the one I struck. On mine the flat bimetallic strip, slightly convex as fitted, has its ends trapped by a long strip fixed to the body of the clutch, with the ends bent up at right angles. The ends of the bimetallic have notches in the centre. After it was too late, i discovered that ONE end of the strip will press down, and then slip out sideways through the end of the bent bracket thing. This will then expose the centre pin that slips out to enable refilling of the working fluid. Then you can push the silicon in with a small syringe quite quickly.
good luck.

I just ordered the stuff a week ago from Toyota Bloomfield Hills in Michigan, and got it within 5 days. You have 3 options :
p/n 08816-10001 (heaviest) ($9.99 per) X 2
p/n 08816-06001
p/n 08816-03001 (lightest)

I went with the heaviest, 08816-10001. Any one of them will work. Go to the Toyota dealer near you and give them that part number. If they try to give you some crap about not having it make them order it. You will get it shortly.

Sorry I cannot help you with your question, but I took a look at your web site and its awesome. Tons of great pictures and well written text. I bookmarked it for future reference!

Thanks for the compliments and the suggestions fellas. However i must say that the thread youse guys are responding to is over 1 year old. My fan clutch has long since been fixed up good as new.

John Pitman - I know. Thanks! You told me that last year and i credited you and Dan the Pod Man, for the sage advice on my page. Both you doods said the same thing. After all the head scratching i did, you cant possibly imagine how dumb i felt after recieving that piece of advice. However, you were just a little bit to late with the dog syringe thing. Next time i'll be ready.

Follow up to the web write up. The T-stat was more the culprit in my overheating woes than my fan clutch.

John,
I had pulled up your post while checking the archives for the over heating problem, your website helped a great deal and I just wanted to update the thread. It won't be the last time someone uses the great website you have set up.
Wish I had known about the the heavier oils before I bought the "thinnest" of the 3 available though. That bit of info really added to the post.

Anthony,

I used the thin oil too. Its not a problem. But in the interest of science, it might be worthwile to do a comparision next time i have to do this.

Good luck to you. Check your tbelt tension while your in there.

Well, the thread might be old but there is a whole new generation of shark owners around here now.
Can anyone give any ideas as to what the symtoms of a failing clutch fan are.
Someone stated that a spin of the fan by hand yielded about 5-6 revolutions. Does that mean the fan needs new fluid?
How many revs should the fan spin if you were to flick the wrist?

Paul D

I just added 2 bottles of the thick stuff (Toyota PN 08816-10001) to my fan clutch and now when I spin the blades by hand the fan stops almost immediately when I let it go. Prior to refilling it would make 1/4 to 1/2 revolution by hand spinning. I hear more noise from the fan (air noise) now that it is not slipping as much.

Bernie

So, to summarize....
When spinning the fan by hand, it really shouldn't spin much at all? Is that right? I spun mind by hand and it will do about 1-2 revolutions. Does it seem like I need to address the fluid?

Cheers
