Vermeer 630 stump grinder pulleys

[Nick H]

Hi. New member to this forum. Any help here would be greatly appreciated. I recently acquired a 630a for free with a blown Wisconsin. Repowering to 22hp vtwin. Im having trouble getting the pulley off of the output shaft. There is a plate on the end of the pulley that looks like an overgrown circlip. Is there a trick to getting it off? It appears Vermeer may have tac-welded the plate and shaft key together but I'm pretty sure I broke it with a cold chisel. Does anyone have experience with these? Don't want to beat and pry the pulley and risk bending it.

Any chance you can post a pic?

Most pulleys I've dealt with have 3 bolts and 6 holes, pull the bolts out of the holes they're in, thread them into the other 3 holes evenly until the pulley just pops off.

Why underpower by 13hp? The w-4-1770/was the perfect motor for that machine. Should be easily rebuild able short of a broken crank.

Because for about a thousand dollars I can have a working machine and thats what i can afford. Just went out on my own last summer. That wisconsin is expensive to repair, heavy and prone to warped heads and detonation. I see similar power/cutter wheel size setups on little self propelled machines. It should work.

Classictruckman you rock. Just turned head scratching into mere minutes of minimal effort. It does have 6 holes. You-da-man
