Default Help with adjusting Volvo Penta Steering

Need help troubleshooting my Volvo Penta DPS-A outdrive steering. Here is the problem when turning the steering wheel to the right the outdrive swings to far and hits the bolts of the hydraulic trim unit (see photo). When I turn all the way to the left they outdrive doesn’t go nearly as far. How do I adjust the stroke so it is centered? It is not the steering cable because I can disconnect the pin and swing the outdrive by hand and get the same results. You can see it hitting the black rod on the end of the steering cable. Looks like it may be the wrong parts? I would at the very least I want it to quit hitting the trim unit.

Any suggestions?

There is no adjustment on that system. My guess may be that someone replaced the actuator (they commonly develop leaks) with a different one than original. I have seen various versions of the actuator but I thought they all had the same dimensions. The cable steering systems all should have the same cable throw also, what type of helm and cable are you using? has anything been replaced?

Looking again at your pictures you have too much throw in the steering cable itself if your bottoming out the tube and bracket when the cable come in and when the cable pushes out it moves the drive so much it hits the trim pump bolts. This would seem to be a helm/cable problem but they should all be the same......the bottoming out is no big deal as that is just a stop but the drive should not hit the bolt externally....close maybe but not hit it hard.

How hard does it hit the bolt? move the ground wire behind the bolt to the other bolt and you'll have another .030 clearance....

Carbo, you are right on thinking the wrong parts because it hits the black rod when the bracket moves to the left. Fact the turing ability of the ourdrive is greatly limited because of this. That is why I am wanting to move the whole cylinder to the left. When I check the hydraulic cylindar below there is still plenty of travel. I just need to get part of the black rod out of the way of the travel.

That is what has me thinking to just modify the black rod by taking if off and cutting of a 1/2 inch. What do you think?

I think the way you described making clearance for the bolt on the outswide is posssible. Fact I even thought of a hex bolt rather than the cap screw.

Let me know,

Anyone who know of a better solution?

Anyone know if the black rod is Volvo Penta part or Teleflex?

I guess I need to explain I found out and provide closure on this thread. As stated I noticed the drive unit hits the housing when turning all the way over. I could never understand why that could happen and if I was really designed my VP to allow that? Never under stood how the steering system can be an unbalance system by design, before you jump all over VP for this goofy design understand the other outdrive builder has she same type of design. You can turn further one direction than the other. Anyway, while figuring all that out my friends (and I do mean friends, great people there) at VP told me there was a cover modification by that factory that changes the cover design and eliminates this porting and plug issue and most importantly keeps the out drive from hitting the cover at full turn. You need to use the Volvo primp cover kit 21573835. I installed an new one and everything is good. It could cause major problem if you crack or break the cover. Long story short version, replace the cover, easy installation. http://www.volvopentastore.com/Cover-Kit-Trim-Pump/dm/store_id.366--view_id.775577 . I guess if I had my work done at the dealer or had the factory manuals I would not have to reengineer this kind of stuff but I find it interesting fun.

Monobill when you talked to VP did they ever explain the reason for the white plugs? I am leaking in the same place as you were....at the white plugs. Looking at the trim cover it looks like the design intent is to prevent water comng in contact with the water and not trim fuild leaking. Per your advice I was going to buy the new cover (2nd generation design), but will this not just result in creating a reservoir of trim fuild between the cover and pump?

Plugs are used to close off the holes made during the manufacturing to cross port of the manifold block. If you look at the way this hydraulic manifold block (part of the cover) is ported it is easy to see. They drill in from the side connecting two hydraulic lines from one output. It is typical hydraulic design and would be good however the white plugs don't stayed glued in the hole. That is why it works to just drill out the plug and tap then insert a SS set screw. The screws replacing the plugs worked great. It wasn’t until I figured out when the drive is turned that direction all the way where it should be hitting the hard stop it hits the cover first, not by much. New VP cover design does not use the same type of porting in the cover, notice hey move two of the lines to the side, and just smaller in size to give clearance. Replacing the cover is the best way to eliminate problems.

To answer your question about the resivior, oil is not behind the cover. When you get the cover off you will see the oil resevior bolted onto the bottom of the pump motor. You should never have oil behind just the cover. The cover has the oil fill hole which aligns with the resevior. Once you get it apart you will see. Photo is with cover off.

Default Volvo Penta Cover Leak

I am new to this forum.

I have the same problem. There is fluid dripping from the white plugs on the VP trim and tilt cover. There is a cover repair kit, new design VP part # 21945911. There seems to be conflicting information in this thread. Do I only need the cover or the pump too? I don't want to order the pump cover repair kit only to find out the pump needs replaced as well. I've read some things that suggest just replacing the cover and others that say that is not really where the leak is. The outdrive is a VP SX-A.

I know this is an old thread but I appreciate all responses. Thank you!

hello tbeyers, sorry for the confusion. You do not need a new pump. You have two options, first is the low cost option and if you are mechanical it's not very hard to do. Take the cover off, drill out the white plugs, tap hole and insert SS set screws. If you are mechanical minded thats not too bad. However this will not stop the outdrive from hitting the cover when you turn hard to that side.

VP had a design change that solve the problem of drive hitting the cover. Although hitting the cover has nothing to do with the white plastic plugs leaking, that is bad bond between white plug and housing. You should be able to stand back there and have some raise the outdrive and you can see the oil flowing out as in my photo. Motor for pump was working fine, just loosing oil. If you want to fix the leak and stop the drive from hitting the cover install the Volvo cover kit #21573835. it's going to cost several hundred dollars but easy to install and solves both problems. In reality the drive hitting the cover is not a big deal unless you have some one cutting the wheel hard when it is at the stop to that side.

Either solution will fix the leak problem. On solution cost about $.80 for two SS set screws but requires skills to do the work. Second options is easy but requires about $300. to buy the cover.

Welcome to THT.
