OTC 7028 Heavy-Duty Clutch Adjusting Wrench for Spicer Clutches

Anyone who has adjusted an internal Spicer clutch with a screwdriver and a hammer knows how that goes. You are working blind through the inspection window, trying to depress the adjusting lock and rotate the adjusting ring at the same time, and half the time you slip and chew up the lock plate. This wrench is the tool the job was designed around. The angled head slides through the clutch housing window, seats on the adjusting ring, and gives you the leverage to walk the ring around one notch at a time so you can dial free play in or out with control instead of brute force.

Using the correct tool matters here because a misadjusted clutch is not a small problem. Too little free play burns the release bearing and drags the clutch; too much and you lose release travel and grind gears. Getting it right the first time is cheaper than a second teardown. The 7028 works on the internally adjusted heavy-duty Spicer clutches found on Class 7 and 8 trucks and other commercial drivetrains.

It is drop forged from high-strength alloy steel, so it takes the load without springing or rounding off, and it will outlast the truck it is adjusting. OTC has been building professional service tools in Owatonna since 1925, and this is a one-tool-does-it lifetime piece for any shop or owner-operator running Spicer clutches. Ships from the USA.
