Valve shim adjustment tool.

[Jonny]

First time doing an adjustment on a vehicle with shims. Intimidating to start, but not too bad in practice. The tools are the key to making it doable, particularly the bucket hold down tool. An update on this older info from another post.....
"It's Toyota Part number SST 09248-55040 and it's available through Kent-Moore tools at 800-345-2233. Price is about $75."
It's now over $120, enough to encourage looking into alternatives.
I used two bicycle bottom bracket wrenches, modestly modified and they worked great. Took a bit of time to grind the hold down to work correctly.
I had theses tools already and I bought beer for a guy with a shop in town in exchange for a shim swap. Total expenditure for the job... $10 on beer.
Edit: All intake valve clearance measurements were in spec, all but one exhaust measurements were too tight (.008" - .009"). Van mileage 200k.
