Volvo DuoProp Wrench?
 

Have heard a few different opinions--is the Volvo wrench the best or does someone know of a better solution for a tool to remove the forward prop nut on a Volvo DuoProp DPS drive?

I've heard it's rather simple to "make" your own taking a deep well socket and marking/grinding to the notches on the nut.

Thoughts are appreciated.

Hi Dave yes thats the best way just grid out the slots in a deep socket ,thats what i did when i had a VolvoDP

I have a spare DP wrench I'd sell

...and be prepared to fight, and cuss, and throw tools if the forward prop has welded itself to the hub....

YEP had that happen had to cut the prop on the big spline off they were alley and i tried everthing broke two pullers spent a day just would not move ,put some nice stainless steel ones back on ,had that drive on the boat 19 years never had to spend a penney on it .

It's about a 450 upgrade.....but waaaaay worth it.

Back in the early 90s i was in the States and was in a parts shop and saw a volvo penta sign up on the wall i asked how much for a set of stainles steel props $ 700+ was the reply i jumped at them , as i was given a price here in England for 1100 pounds and at the time you got 2$ to the pound which made them $2200 .
Thats about the best deal i ever Regarding boat stuff.

First time I saw the genuine Volvo tool I thought it to be pretty Mickey Mouse. They actually work pretty well. A lot less work buying one than sawing up a socket .BTW ,It would have to be one deep, deepwell socket to modify to fit over inner shaft. If you own a Volvo duo boat,you should also own the correct prop wrench ...Won't help you on seized splines though.

How would one go about getting the proper torque on the forward prop nut with a self-made rig? My boat yard had several self-made prop nut gizmos but none where made from sockets so no torque wrench connection.

Here's how a torque value can be achieved without a dedicated torque wrench-

Take the torque value, say 100 ft-lbs, and divide it by the length of your wrench, say 9" (.75'). 100/.75= 133 and this is the force you need to apply to the wrench. A longer wrench, cheater?, obviously makes this easier to do, but you'll need to account for its weight if it gets too long.

Keep the wrench horizontal, parallel to earth, and the force going straight down to prevent any geometry errors. That's
