valve clearance on 1HZ!

Hi
if you only have one or two to adjust then you can use 2 screwdrivers to remove the shims make sure that the piston is not at top dead when you push the shim down as you could bend the valve
regarding the shims you could find a machine shop that has a surface grinder to grind the amount of clearance you need
or the engine recondition shop might have some second hand ones with the right size
What i do when if i am doing all the tappets in the car is measure all the clearances
then take the cam out and place the shims in a egg carton one side exhaust one side intake make sure you mark the egg carton in & ex 1TO 6 and mark the shims (1e or 2I and so on)

If you do pull the cam out make sure you set the cam up so the timing marks on the cam are at the 9 o'clock mark that way when you put the cam back in and bolt it down the valves will not hit the pistions

Hi husky,

I guess if you have steady hands you could use two screwdriver. I made an SST out of 1 inch flat steel so that its width was tapered and would hold the bucket down. I can post a photo tomorrow if you want, I just started with the flat and fine tuned it with an angle grinder until it worked. I also bought a magnetic pickup to lift out the shims, they seem to stick in because of the oil film. Free them first with a fine screwdriver. You will need a micrometer to measure the shims. I bought genuine Toyota shims - I didn't know of anywhere else to get them. I have an Excel spreadsheet that computes the required shim. Let me know if you want me to email it.
Many posts here said don't try it youself when I put up a similar query - LOL.
Try an archive search.

Husky,
Photos of SST now in my photo gallery.

The spreadsheet is the same one I used.

Hi Husky
What you have done is ok by setting the cam at 12oclock it just means when you put the cam back in you have to make sure the that the cam is set up at 12oclock
Because at 12oclock number 1 and 6 pistons are at top dead centre and if the cam is out by a bit when you tighten the cam down the valves can hit the pistons

When the cam is set up at 9oclock timing marks the pistons are are down the bore so when you tighten the cam down the valves will not hit and also you can turn the cam with out hitting the pistons so you can check the valve clearance with out the valves hitting the pistons

on the cam cover there is two timing marks 1 at 9oclock as witch is for taking the cam in and out and one at 12oclock for top dead center witch is for setting the timing with the pump gear
the fuel pump gear cover has the same two marks one at 9oclock and one at 12oclock

When you tighten the cam down make sure you tighten it down evenly

hope this helps

LOL!

Robert, I have just seen on your profile and I see that you have indeed a different vehicle. Juct for clarification, for anyone else reading this post looking to do their shims on a 1HZ diesel:

on the 1HZ TDC = 9 o'clock, and BDC = 12 o'clock
