MU 200178300

Frequently Asked Questions

Q: What is the purpose of the MU 200178300 snap ring?
A: The MU 200178300 is an OEM wheel retention snap ring designed for axle assemblies in Multiton manual pallet jacks. It holds load wheels and steer wheels in place on the axle shaft and prevents axial movement during operation. This snap ring is a critical safety component that must be properly seated in its groove.

Q: Which Multiton models use this snap ring?
A: The MU 200178300 fits Multiton TM, M, J, and S series pallet jacks. It is used in both front steer wheel and rear load wheel assemblies. Verify your exact model and serial range before ordering, as axle configurations may vary between series. Measure the axle shaft diameter and groove diameter to confirm fitment.

Q: What material is this snap ring made from?
A: The MU 200178300 is manufactured from heat-treated carbon steel to ANSI B18.27 standards. Heat treatment provides the elastic strength required for repeated snap and removal cycles without permanent deformation. The snap ring retains its spring tension through multiple maintenance cycles of wheel removal and reinstallation.

Q: How often should this snap ring be replaced?
A: Replace the MU 200178300 if it shows visible cracks, permanent bending, or loss of spring tension. Do not reuse snap rings after wheel removal if they have been deformed or if the groove edge is worn. New snap rings are inexpensive compared to unplanned downtime from wheel separation. Replace preventively during routine wheel or bearing maintenance.

Q: Does this part require any special maintenance?
A: The MU 200178300 requires no special maintenance beyond visual inspection during wheel service. Ensure the groove in the axle shaft is clean and free of corrosion before seating a new snap ring. Do not apply grease or lubricant to the snap ring or groove, as this can reduce friction needed for proper retention.
