Description
A 3/8 in torque wrench is easy to carry and easy to fit into a crowded engine bay. On its own, however, it cannot reach heavy bolt values. The Snap-on MTMC730 torque multiplier closes that gap. This compact manual gearbox takes a 3/8 in drive input and delivers up to 730 ft-lb, or 1,000 N·m, at its 3/4 in output.
Small input, big output
Inside the housing, a gear train trades turns for torque. So the operator turns the input wrench many times while the output turns slowly with much more force. Because the Snap-on MTMC730 torque multiplier is manual, it needs no air, power or battery. That makes it handy for field service and remote sites.
Choosing the input wrench
Output torque equals input torque times the gear ratio, less a small loss. Therefore, read the ratio and any correction factor on the label or in the Snap-on manual before you set the wrench. Then divide your target by that ratio to get the input value. Also pick a 3/8 in wrench whose range puts that input value in the middle of its scale.
Good jobs for a compact multiplier
- Axle, hub and suspension bolts in truck and bus workshops.
- Gearbox and motor mounts where a long bar will not fit.
- Generator and pump bolts on remote or offshore sites.
- Agricultural and construction machines serviced in the field.
Reaction and safety
Every multiplier needs a reaction point, because the housing tries to spin the other way. So rest the reaction foot against a solid part, such as a nearby bolt or a frame member. Never hold it by hand. In addition, keep fingers away from the foot while the joint tightens.
Looking after the Snap-on MTMC730 torque multiplier
Wipe the drives after each job and check the output square for wear. Store the unit in its case, away from water and grit. Since the result also depends on the input wrench, check both tools with an independent calibration lab at the interval your quality plan sets.

FAQ
What wrench drives the MTMC730?
It takes a 3/8 in drive input, so a 3/8 in torque wrench or ratchet fits it directly.
What is the highest output?
The rating is 730 ft-lb, which is 1,000 N·m, at the 3/4 in output drive.
Does it need power or air?
No. It is a manual multiplier, so your input wrench provides all the effort.
