volvo penta 270 seal kit

[Dalejam]

It has been a long time since i have been back, Boat has been great till..... motor is a AQ125A BAYLINER CAPRI 19
I found small droplits of a cream color in the water behind my boat after running for a while. i checked the bellows for leaks could not find any. so i pulled the boat out of the water to make sure i don't contaminate the water, also fix my problem. so i took the out drive off and when i did i found the cream color substance it was in the bellows of the driveshaft.
I watched a video on youtube of a guy taking his outdrive apart and followed his leed. i have the same problem he did bad seal, O ring etc.

SO here is my question do i buy aftermarket kit from Iboats Mallory 9-77902= $57.84 or Volvo OEM 876266= $170.00 and change. called Mallory they told me the seal for the bearing is in there kit.

Re: volvo penta 270 seal kit

What kit are you buying? What repair are you doing? If you have outdrive fluid in your bellows, your upper gear box needs resealing. This is not a DIY job, imo.

Glad to hear your on top of it however, further neglect and you could have lost your whole outdrive.

Welcome back...

Re: volvo penta 270 seal kit

I am purchaasing the upper gasket kit for the volvo 270 outdrive.

I have a leak where the universal joint yoke goes through the housing and connects to the drive gear.
when i put it all back together and put a little bit of air through the Dipstick level is on the outdrive, I can hear air leaking from behind where the two units meet up in the housing. I sparayed some Joy bubble mix on it and put air into it again and i can see that it is leaking bad. so when i looked at the bearing seal it was damaged and the O-Rings seem to be a little worn.
I think the Gear oil got up in the drive shaft because the pressure that builds up and the seal failing allows it to go there.

Thanks for replying

Re: volvo penta 270 seal kit

Personally, I think you are looking at your problem backwards.
Original failure was the bellows. Water in the bellows = water in drive = water oil mixture back in bellows when drive heats up.
I would be pulling the back seal out of the flywheel cover and looking at the grease. If it's milky, time to pull the engine and replace the primary shaft bearings.
You will need new ujoints, and bellows too.

Might want to have a look at the Volvo section up in the Adults only sticky. Lots of info you NEED.

Re: volvo penta 270 seal kit

I might be going quick but the oil in the bellows for the drive shaft was gearoil (smell and thickness. the plate where the shaft comes through the hull was dry grease was on it but that was a good thing.
i checked the bellows looked good at inspection time. i read in the sticky notes that the outdrives should hold up to 11 psi, mine won't just putting air into it and it leaks right out.

so what i have found is it is gearoil in the bellows not motor oil. since the only place gear oil is in the outdrive. that is how i came up with this answer. plus the air test failing....?
am i correct.

Re: volvo penta 270 seal kit

Absolutely it's gear oil. Oil from the engine can not get into the bellows.
One problem with your gear oil smell. Your drive is supposed to have engine oil, not gear lube in it.

Re: volvo penta 270 seal kit

The only reason i know its Gear oil is, I put it in there 2years ago. the local marina here told me it takes gear oil in the lower outdrive unit. he sold me the pump that goes on the bottle and the gear oil. that is why i know it is gear oil. after reading about the out drive i found out any oil of 10w/40 or higher is fine for the outdrive.

So i know its gear oil trust me i know, so is it ok to purchase the aftermarket kit versus the OEM.

As for the pressure test just blowing air into the hole where the dipstick is to be i can hear the air leak out quick. According to sticky notes is the outdrive 270 also to beable to hold 11 psi pressure?

Thanks for the reply.

My mistake, didn't mean to intrude on your personal inturpritation of how things should be done.

Re: volvo penta 270 seal kit

i'm not sure what you mean about my interpertation of how it works, i am seeking help from the MASTERS (YOU) and i can only document what i have done so people can tell me if i am on the right track or if i am off base.

You have always been helpfull to everyone and i appreciate your time and everyone elses input in helping me.
1) Can you tell me is the volvo 270 outdrive also to beable to hold air pressure of 11 psi or less and for how long.
2) what type fluid should i put back into the outdrive book says 2.8 qts i know check to see if you need more or less.
3) is the after market kit for the 270 upper gasket kit worth it versus the OEM.

Thank you always

Re: volvo penta 270 seal kit

1. yes it should hold pressure, i'm not sure of the amount.
2. Motor oil.
3. I would buy the OEM.

I would find a local mechanic who can reseal and reshim your upper gear box. If it is not done right, the drive will not last.
The typical reason for the seals to go out in the upper is from water in the bellows. Once water enters the bellows, it corrodes some parts which wear out the seals and cause the leak.

Re: volvo penta 270 seal kit

What type motor oil should be in the outdrive, synthetic or not , if someone could be very spacific that would help me alot.

When i took the outdrive apart i was able to see all the shims and noticed the O-Rings were a little out of shape. so i am going to replace all the rings and seals.

The boaat has been good to me because i take care of the problems as they arise and not turn up the radio and ignore them.

Re: volvo penta 270 seal kit

I use sae 30 non syn.. I don't think the outdrive really cares.

Once the upper is dismantled and the parts are replaced the unit needs to be reshimmed and the bearing need to have a preload adjustment. I do not have the proper tools or knowledge and I would guess you don't either.

I'm a fan of the older Volvos as well, but I know my limitations...

Just like a car, some jobs are best left to a pro. Just make sure the pro knows how to work on the older volvos.

Just trying to warn you, not trying to discourage. However you choose to do it, do it correctly or suffer worse breakdowns in the future.

Re: volvo penta 270 seal kit

Is it possible to purchase shims, i could find out what the thickness is by a micromater. just want to know how much i can do versus paying someone. trying to save money feeling the pinch from the economy.

Re: volvo penta 270 seal kit

Don has been amazingly generous with sharing information. It just Sometimes takes a little while to find in older posts. Very few problems are "new" or unique"... Too many (a good thing) Volvo Pentas out for that.

Some time ago he posted this in regards to the "lube" oil for the outdrive.

Hence, I would look in the operators manual for your engine, and follow that recommendation.

Mine, (AQ171C, I-4, DOHC) takes "Multigrade 10W/30 or 10W/40 according to manual. I use regular "mineral" oil, not synthetic.

you need to measure for the shims. You don't just put back what was there. I've never tried it. Once you save money repairing your outdrive, you'll be saving for a new boat soon after if the repair is not correct. Come on, why would I make it up. If I thought I could rebuild an Upper, I would have attempted it already. Sorry, but I don't think its a good idea. Check around, you may find someone reasonable...

Re: volvo penta 270 seal kit

I agree with you 100%
i dont wan't to get introuble for going of topic even though this is nothing more then GRATATUDE to everyone in the forums for helping others.

I have gotten the proper information that i need and i will order my parts and when they show up i will rebuild and i will post my results to let everyone know.

Thank you all.

Re: volvo penta 270 seal kit

I will shop around and make phonecalls, does anyone no any shops in northern New Jersey, also a price range to have it reshimed?

 

[captmello]

Re: volvo penta 270 seal kit

I was quoted 500+/- to rebuild my upper a couple years ago. that included seals and new ujoints. Just make sure they have someone experienced with the old volvos. There usually aren't many so the local marinas may know who specializes in the older stuff.

Good Luck! Let us know how it turns out.

Re: volvo penta 270 seal kit

I would also suggest not shimming it your self. You need to get the preload just right or you will seize your drive. Trust me I know. Happened to my dad's boat after someone who was not experienced enough did it for him.

Re: volvo penta 270 seal kit

Bearing preload is only part of the process, gear contact patterns is even more important, if you want the gears to last.
It takes me about 3-4 hours to reshim an upper gear box using old gears and new bearings, along with having all the special tools to do the job. But I have also been to the Volvo schools and have rebuilt around a hundred or so of them over the years.

Here is a link to the OEM service manual. http://www.4shared.com/file/51930153/3a7e6375/270_Outdrive_service_manual.html

You really need to go through this manual and figure out what is really supposed to be going on.
