- description
A shaft guide supports the motor shaft where it enters the gearbox, holding the pinion in line with the bevel gear instead of letting it wander about under load.
When it wears, the pinion starts to move. You hear that as a rising whine under load, and you see it as uneven wear across the bevel gear teeth.
Our supplier lists two, which appear here as options: a standard guide, and one described as long axle, D type. They do not explain how the two differ beyond those names.

Good to know before you buy
Because the difference between the two versions is not documented anywhere we can find, compare the part you are removing against the option names before choosing. If neither is an obvious match, ask us first.
Frequently asked questions
What is the difference between the two?
Our supplier names one standard and the other long axle, D type, without explaining further. We have not been able to confirm the distinction, so we are not going to describe one.
Do I need one when changing a motor?
Not automatically. Inspect the existing guide while the motor is out and change it if there is play or visible wear.
Will it fix a noisy gearbox?
It can, where the noise comes from pinion movement. Motor height and shimming produce the same symptom, so rule those out as well.
