timing belt on 95 Lexus

Share this page

Wow Banjo that might be it when you say the flange is different because I put the front one on the same as the back. When you say flange do you mean the center webbing? I can tell that if I flipped it around there would be more room, but the center webbing would be different front and back, plus I thought that would affect the belt travel. My first thought was I had the pulley on backwards, but the timing mark is looking right at me. I guess there could be a mark on both sides. The book shows to pull the cover and hold the cam by a hex on the cam when removing the sprocket, and I did that. Now that it looks like I should take it off, do you think I should do that again. Moreover, do you think I should totally remove the belt or just try and flip the sprocket around by undoing the tensioner and clamping the belt? My gut reaction was to pry that metal cover out and wiggly the pump out, but I could not tell how far it went back behind and plus I was afraid the belt would rub!!!! now the pulley rubs!!!!!!
Thanks again Banjo
 
By "flange" I mean the one side of the pulley has the shoulder, or ring that sticks out beyond the gear teeth. The back pulley has on on the outer side, but the front one has on on the engine side. It should have the little timing mark notch. there is a second mark on the edge of one of the teeth that is for the paint marks on the belt. I think, if you do need to "flip" the pulley, it's gonna require you to take the belt back off.
PM me your email, I have a PDF file for you.
 
Thanks Banjo you have been a tremendous help. The vehicle is at my friend’s house and when I got there I saw what you meant by a flange. I pulled the belt and flipped the sprocket over and that looks like it will give the wiggle room/space I need for the pulley. Incidentally, and much to my surprise there are timing marks on both sides. I guess you could put the pulley on either cam and put one flange in and one out that way? Perhaps the flange acts a belt guide? I do not know. But when I put it togetherthe first I matched them up. I am going to try and start it later today; wish me luck.

The opposing flanges do indeed maintain belt alignment at the top. By making ONE drive pulley for both cams it cuts expense and is a simple way of keeping the belt on the cogs.

EDIT: Yeah, Jesse, Sir Colin was a crafty ol' lad. The cam cogs are EnFo cam wheels, indexed for his Cossie designed app. The Kent block kept the original cam and wheel, simply to drive the dizzy and oil pump. Many of those have been replaced by a "skinned" jackshaft with only the gear. All very practical. </span>
