How to Access the Gears for the Heavy-Duty 12000 lb Bulldog Jacks
Products Featured in This Question
Question:
One of the guys at work cranked the jack all the way down again the chain stop we put on so they could not run shaft off of the nut and it broke the pin on ring gear. How do I get the jack apart to replace it. I would like to have a breakdown of how it works.

Expert Reply:
To access the gears inside of the heavy-duty Bulldog jacks, like part # BD182415, you simply remove the screws that are holding on the plate covering the top of the jack. Once that plate is removed, the gears, pins and handle should be exposed.
We also offer the Replacement Screw and Nut Kit, # BD500217, for the heavy-duty 12,000 lb capacity Bulldog jacks. I have attached two photos that show the inner workings of the heavy-duty Bulldog jacks for you to check out.
The cross shaft that connects to the handle should be attached to the 12 toothed bevel pinion with a straight pin. You can remove the straight pin to remove the cross shaft, spring and bevel pinion. With that removed, the 18 tooth bevel gear will be exposed, and that is attached to the screw and nut assembly with a grooved pin.
If you have any further questions, just let me know.
