Timing Belt is now replaced

I changed my timing belt and water pump this weekend on my 93 SC400. Real hard job - I spent maybe 14 hours total. But I'm happy i did it. I had 117k on the engine. TB is in great shape. The water pump had been leaking - that's why I did the change out. This weekend I'm going to upgrade my A/C to R134a. All the R12 leaked out.

do you have the special service tool for holding the crank pully when breaking the nut on it?

Tools

Frank,

There are a bunch of "special" tools that the service manual refers to that are to be used. One is the crank tool, but there are some other special tools called out as well. Did you use substitute items, or did you get all these specialized tools?

I will be doing the belt on my 93 400, so I wanted to check before I get into it.

Thanks!

spcl tools

I did in fact get the spl tool as well as the handle that attaches to it. They are listed and sold separately. I also got a brekaover bar and an extra log 7/8" socket. Lastly, I got two 4' long steel pipes to use as cheats. Let me tell you, that bolt just melted off. It was a great feeling. the bolt is standard threaded - lefty loosey. The only other spcl tool i got was a pulley remover for the crank pulley.

the manual specified taking the sprak plugs out. don't do it. leave as much attached as you can. you have to take loos the idlers, fan pump and alternator. I took the 2 front bolts out of the a/c, but left it hanging.

you might want to also replace your rotors and rotor caps as well. It's only an extra 60 clams, but it's an easy change while you're up in there.

That spcl tool made all the difference.

Good luck ya'll

Thanks for the tips!

Frank,

I am ordering the stuff from Carson Toyota now.... I would HATE to take it all apart this W/E and find out that I couldn't get the crank pulley off.

Looks like I will have a busy weekend!

Thanks again!!!

One more Question

Frank,
One other thing. The Service Manual says you need to remove the crankshaft timing pulley (yet another tool). I don't see why that is required, as the belt slips off that. If I wanted to change the front seal, I could understand. Did you pull that pulley (gear)?

Thanks,

Jezz!

Looks like it is gonna be an interesting job. I ordered the crank pully bolt-buster tools from Carson Toyota, but bought the puller from Harbor Freight, or as I like to say, disposable tool supply. The tool for removing the crank gear is $700.00 from Toyota, so I don't think I will get one of those. As I said, I see no use for that unless you are changing the front seal.

I bought all new belt idlers and the tension gizmo. I figured once I open this up, I don't want to do it again for another 100k miles. I also will change the water pump, so every stinking part will be new. If I had this done at a dealer I bet it would run $2k.

I also bought brake pads and shimm kits. For the whole bannana it was 500.00 and change for Govener Davis w/othe water pump (I have a brand new ABSCO I had bought some time ago, they are Toyata's parts supplier in Japan). Sound like a lot, but when all said and done, the front won't be comming appart for a long, long time.
