what sizes are the adjuster and lock nut on caltracks?

1 1/8"

Buy a thin, short 1-1/8" wrench from McMaster Carr, PN 5403A25 (or cut one down from a swap meet). About $20. Sooooo much easier to use when the car is on the ground.

Gezz I did't know what I wrote did not show up !!! someone on here just turn the bar around and put the ajuster on the back. easy to get to..I look at mine looks like that will work great.

Harbor freight buy one end wrench cut it in half and then cut another portion out of the box end, so it will slip over the bolt.Works great

The 1-1/8" angle wrench out of this harbor freight set. For $20 a set for 3/8" through 1 1/4", It's a steal. I only carry the one wrench. The nuts don't need to be torqued down, just snug. -Tom.

If your a carpenter and own a router the spanner wrenches work perfect on the cal tracs adjusters

dont cut any more wrenches down, just go to Home Depot and buy the small Channel lock crescent wrench, it is small adjustable and works great.
