Newbe here Help needed with volvo penta AQ130D 280 outdrive

[ranger55]

Hello, first boat. It is a 1976 Tahiti with a volvo penta AQ130D, I believe, 280 outdrive, There is no metal label on the engine for id, is there any other way to ID this motor... I have repaired water leaks at the exhaust elbow and impelller housing. Now major oil leak at the rear of the engine. The leak looks to be coming from flywheel cover, or bell housing. Couple of question that maybe the forum could help me with.
1. Could this be the rear engine seal, or could it be some other seal?
2. If it is the rear seal, motor would have to come out of the boat I presume. How difficult is this, and would I have to remove the out drive to pull the engine.
2. Can anyone recommend a good shop manual for this motor?
Thanks in advance

Welcome to the forum ranger. Differences between the AQ130 C and D are minor until you get into the engine internals. Even then, you can tell the difference by the number of bolts on the crankshaft. 8 on the newer D (This is the Volvo B20 E block) Differences are the wrist pin sizes and big end bearing sizes. The 130D was normally mated to the 280 outdrive.
To answer your questions:
1) Yes it could very well be the rear main seal. It's a felt seal and can dry out or wear out over time. Readily available from Volvo or any auto parts store. If you like, there is a neoprene replacement available.
2) Engine isn't difficult to remove. Wiring harness has a large plug to make that part of it easier. No need to remove the complete outdrive, just the upper gearbox to remove the engine.
3) Manual can be purchased from Volvo or from these guys: http://www.marineengine.com/manuals/volvo/volvo_penta_sterndrive_gas.html

Thanks pirate past 40. Got a lemon here, but will have fun making lemon aid...Can you tell me how to remove the upper gear box?

Re: Newbe here Help needed with volvo penta AQ130D 280 outdrive

Here's a thread about removing the upper gearbox: http://forums.iboats.com/showthread.php?t=309095
It even has the parts list.

This forum is full of useful information. Do yourself a favor and do a search for "AQ130D". You'll find many many threads about your engine. A similar search for "280 outdrive" will open other doors for you. The "Adults Only" sticky at the top of the forum also has a ton of useful information. There is even a link to the Volvo web site with free owners manual for your engine.

Don't know how experienced you are with boats so please don't take this the wrong way. It would be a good idea to have someone with experience do a detailed inspection of the hull, transom, stringers, and deck. You would be very upset if you put a lot of time and money into the engine and drive only to find out that the hull needs tons of work and money also. Not that many of us here haven't been there! :redface:

Re: Newbe here Help needed with volvo penta AQ130D 280 outdrive

Hey pirate, thanks for the heads up on the upper gear box. Have another question on this volvo penta 130D. Getting ready to pull the motor and going to use two come alongs from the rafters of the garage. Not sure I like the setup where the ring to be used to pull the motor is, exhaust elbow, is there a better way? This looks a little shakey to me. Using two come alongs, any suggestions.
Thanks

Re: Newbe here Help needed with volvo penta AQ130D 280 outdrive

There should be another lifting eye on the opposite side of the engine at the front of the head. If the lifting eye isn't there, use your imagination to rig something up. A bolt screwed into the head will work.

Weight is about 250 lbs plus the weight of the flywheel cover. When you start to loosen the clamping ring bolts (the ring at the rear of the flywheel housing, and accessed from outside the boat), the weight will shift to the hoist. If it seems stuck, there are additional threaded holes on that ring that can be used for jacking bolts.

There are a couple of options for that rear seal. For those of us who aren't professional mechanics, the felt seal is a bear to get onto the crankshaft . Here's one with a plactic sleeve to make it go on easier: http://www.ipdusa.com/products/8973/120268-rear-crankshaft-seal-b20-b21-b23-b230-b234-b30

Here's an updated housing with a newer neoprene seal: http://www.fcpgroton.com/product-exec/product_id/17742/nm/Volvo_140_Series_Rear_Crankshaft_Seal_Kit_1967_1974_MTC_/category_id/121

Re: Newbe here Help needed with volvo penta AQ130D 280 outdrive

Thanks again pirate paste 40. There is only lifting eye on the exhaust elbow should not be a problem. As far as options on the rear seal couple questions. The updated housing with a newer neoprene seal says 140 series."Volvo 140 Series Rear Crankshaft Seal Kit 1967-1974 (MTC)" will this seal work with my motor AQ130D? and is there a difference, is one better?

Thanks again

With the older engines you need to get creative. The AQ130 is a Volvo B20 engine. Most automotive block parts and gaskets will work just fine if you can't find the marine version or you're shopping locally. I've used the kit with a new housing and neoprene seal on both a 130D and 130C. The one with a plastic insert is something new, I hadn't seen that one until now so have'nt tried it but can see how it would slide on easier than the felt seal.

There are some "while you're at it" things to take care of if you're going to pull the pan. I'd also replace the oil pump seals and the front seal and gasket since they could be dried out. Same with the valve cover gasket. Those are relatively cheap and will possibly save a mess and some work later. I'd also consider rebuilding the carbs unless you feel they're in good shape.

The other routine maintenance items are the PDS bearing (inside the flywheel cover) and seal replacement and U-joints. Simple jobs but can cause quite a bit of damage if they go bad.

Re: Newbe here Help needed with volvo penta AQ130D 280 outdrive

Helllllp, pulled the motor and replaced the real seal motor back in and still leaking oil, though it does not seem to be leaking as much. I did notice that the housing that holds the rear seal looked to be scored a little around the bottom inside lip. Could this be why it is still leaking? Going to run it a couple of times and see if it seals, but doubt it. Any suggestions on anything else it could be anyone? Will pull the motor again but would like to run it outside to boat, can this be done? Has anyone ever built a stand out of wood for this motor? Thanks for any and all help...

Re: Newbe here Help needed with volvo penta AQ130D 280 outdrive

Sorry to hear you're still having problems. It sounds like it could be the surface of the crankshaft at the seal area or the oil pan. Hopefully, a professional mechanic will chime in with his opinion. As far as the engine stand, I've got one from Harbor Freight. Not the super heavy duty one but not the cheapest either. I've run the litte 4 cylinder engines on this but it probably wouldn't be a good idea to run a larger engine on it. If you do a google search for AQ130, you'll find a few videos of people running different engines on a wooden pallet. That should give you an idea of how to block it up if you don't want to do it on an engine stand.

Re: Newbe here Help needed with volvo penta AQ130D 280 outdrive

do you have a clogged breather system? even with new seals, if your positive crankcase ventilation is clogged up, it's going to leak oil. if the PCV is okay, there could be a pinhole leak in the oil pan, the rear crank housing gasket could be leaking, did you check that when you did the rear main? there could also be a leak in the oil pan gasket.

it's very hard to diagnose an oil leak over the internet, they are one of those things you usually have to figure out for yourself. you will need to clean up oil residue to the best of your ability and run the engine, carefully watching for where the oil is coming from. you may need to run it for a while then squeeze yourself behind the motor with a mirror in hand and a flashlight to locate where it's coming from. sometimes it's very hard to locate an oil leak unless the engine is running and the oil is hot.

you could help us by getting some pictures of where it's leaking and someone might be able to help you better but no guarantees.

Re: Newbe here Help needed with volvo penta AQ130D 280 outdrive

Great News, oil leak seems to have stopped. Ran the motor for ten to fifteen minutes for a few days in a row and not a drop the last two days. Had a small leak at the fresh water pump, replaced the seals in it, and it no longer leaks. The motor does seem to be running a little hot, according to the idiot gage, don't know how accurate it is. Going to pull the thermostat tomorrow and see what temp it opens at. Will be looking to buy a gage and sending unit that shows temp to install on the dash, any suggestions? If it still heats up will pull the oil cooler. Really appreciate all the help from this forum.

Re: Newbe here Help needed with volvo penta AQ130D 280 outdrive

very good then. glad the leak stopped. you were probably seeing the excess residue seeping down that's typical even after the repair is completed. it takes a while for all of the oil residue to go away. i even tell customers that after repairing an oil leak, i've cleaned the area to the best of my ability but there still may be some residual drops and do not be alarmed. you can't clean everything perfectly.

Re: Newbe here Help needed with volvo penta AQ130D 280 outdrive

Any air leak in the suction side of the raw water system will contribute to overheating. The "water neck fitting" just below the gearbox is a wear item and can corrode from the inside causing the water pump to suck air. There are other possible causes such as, the inlet strainer and an o-ring in the water pick up tube.

It's a bit messy, but it's possible to pressurize the inlet system by holding the muffs tight and blocking the hole at the bottom of the outdrive. Have a helper check for leaks at all three common leak spots. Better yet, have the helper get wet and you check for leaks .

Re: Newbe here Help needed with volvo penta AQ130D 280 outdrive

Back again, got the boat on the water today. Overheating badly! The way this boat is setup is it is drawing water through the rawwater pump from the bottom of the boat, below the motor. The hose coming from the out drive has been plug off, so no water is coming through the outdrive. It almost seems like the thermostat is not opening,but I have checked the thermostat and it does open at 129 degrees. There are no water leaks, or air leaks. Any help or ideas would be Really appreciated.

Re: Newbe here Help needed with volvo penta AQ130D 280 outdrive

Check your raw water pump impeller. If you cannot confirm that it was replaced in the last year, replace it. I think there's also a companion flange behind the impeller that drives it. If that coupling piece fails, the impeller won't turn and it will overheat. Also check the seals for the circulating tubes and the gasket on the pump itself, if those are not sealed completely it won't pump properly.

Basically, you need to start first things first. Replace raw water pump impeller, make sure the coupling piece for the impeller isn't broken, check that the gaskets are new and sealing properly then run it. If it still overheats, and it's likely that it won't, report back and we will continue diagnostics.

Re: Newbe here Help needed with volvo penta AQ130D 280 outdrive

Try bypassing the strainer since any air leak on the suction side will affect water flow. Check your oil to see if it's milky or the level has increased.

 

[ranger55]

Re: Newbe here Help needed with volvo penta AQ130D 280 outdrive

It's the boat that keeps on giving. Replaced the impeller and gaskets, no leaks, the impeller is turning and putting out water on the other side of the pump. Not sure how much pressure there should be, but it looks a little like the garden hose turned on low, still overheating. Pulled the thermostat ran for a few minutes still overheating, Hello Pirate, there is no strainer, it has already been bypassed. Checked the oil, there is no increase in the level and it looks fine, not milky. Could it be that the oil cooler is plugged? Tomorrow I guess I will pull the pipes at the thermostat housing, run it to see if water is getting up there. Any and all suggestions muchappreciated.

Re: Newbe here Help needed with volvo penta AQ130D 280 outdrive

The oil cooler would be the next bet but the exhaust maniflod could also be rusted up and plugged. Is this a salt water boat?
