Drill Hole in Volvo Angle Gear for Drain UPDATED

Need some advice please - was planning on changing the angle/bevel gear and diff fluid this morn on my '05 xc70, started with the bending/bevel gear. As I'm threading the thin rubber tube (6mm outside diameter) downwards into the bleed/fill hole it got stuck. I tried pulling it out gently but I think a piece broke off inside the housing. Non sure how long of a piece simply can't be longer than 1/two inch. What do I do now - bulldoze it with the hope that the gears will grind up the piece of condom (then do some other fluid change after to ensure make clean fluid) or does it need to be opened up and the piping removed? This is not going as planned!

Why do you guys try do jobs like this when you lot really don't know how, seriously?
A relatively elementary job becomes a nightmare (or worse).

I have so many (local) people enquire me to assist them out when they are in the centre of a timing belt job, all apart and they mess it up.
What am I supposed to do, they can't bring information technology to me at present and I'one thousand not a travelling mechanic

Now you're going to accept it towed to a Volvo dealer, have the angle gear removed, the case opened and hopefull they can try to detect the errent broken piece.
(Of grade if you lot think you tin remove it get alee only there is a specific way to reseal them, you need to chafe the case a specific way to ensure a proper seal)
I can't think of another style, but you lot tin't leave it in at that place

Thanks for the advice - like I said I'chiliad not sure how large the slice is that broke off but to be safe I'yard going to accept it towed to my local indy on Monday morning. Can't believe I did that - have a feeling this is going to exist expensive.

Requite the kid a break. At least he was trying to practice the work himself and sometimes i learns best by royally screwing up. I'chiliad sure that you have had such situations come up in your life as nosotros all have had. The fox is to not do it again and exist humble enough to admit that you aren't perfect.

At present to the task at hand, this is not a proficient situation. What I would suggest is that the hose be closely examined to come across if there is show that a slice has indeed cleaved off. See if there is a ragged edge, etc. (assuming that you started with a hose with dainty square-cut ends) indicating a pause. If both ends look like they did when y'all started the chore, I wouldn't worry almost it. If, however, yous have a jagged finish then more than probable you have left a slice in there.

The problem with a rubber hose is that it isn't going to deliquesce in the oil. Nor will information technology easily break downwardly. But I really don't know how thoroughly information technology could get ground up by the gears or if it would just sit down on the bottom of the instance. Odds are that information technology would be basis up and being condom would not damage the gears whatsoever. Lesser line is that if you are sure you lot have a piece in in that location and yous want to take it absolutely rubber, so you lot need to pull the unit and tear it down. If y'all feel lucky and don't heed taking a bit of a chance, drive it for a week, then make certain things are squeamish and warm and re-practise your lube change taking care not to lose a piece of the hose. In fact, make sure you use a clear plastic hose. These seem to be a bit tougher and volition not intermission as hands as they normally stretch first.

Finally, learn from this feel and exist more conscientious next time by thinking ahead a bit.

Good luck,

The first fourth dimension I replaced my bevel gear fluid I had the same sensation that I had lost a piece of the plastic tube coming out. Fortunately, after checking the ends like Bill suggests, information technology proved otherwise. I fully concord in Bill's analysis.

Cheers - yes I compared the two ends and in that location's definitely a deviation in texture. So i'k adequately certain a piece bankrupt off - like you said at present information technology's a example of either driving it like this (and it it breaks and then spend money on labor and material to fix it) or spend money on labor now and go information technology checked out. Any idea how much piece of work this is for a garage - are we talking a couple of hours hither or days?

There should be a big warning about rubber tube breaking off when irresolute both existent differential oil and angle gear oil.

The typical DIYer'south instinct is to effort to get all of the oil out and people end up pushing their luck and threading the rubber hoses deeper and deeper. If it gets defenseless around a gear molar and pause, we end up with this situation.

A much better solution would be just to become what yous tin out and put new stuff in rather than button your luck.

I had no problems with the bending gear only the rear differential is catchy. You demand really thin tubes to bend past the blockage but later the filler hole. Sparse tubes means information technology is much easier to break. I threaded information technology really deep in there and almost didn't go it out without breaking.

Anyhow, we should warn DIYers so people don't follow their natural instinct of getting everything out and push button their luck too far. And yes, all Volvo had to exercise was to put a drain commodities in and there would exist no problems

Every bit for OP, the only way to exist certain is probably to take the AG out and opened information technology upward to get it out

I haven't done this and peradventure it is not a great thought just I've read in the past about steps that tin exist taken to add a drain to the bevel gear housing. An example is shown at this link.

If the car were driven for a couple days and the referenced process was used to create a drain would this not exist an effective way to get rid of any ground upward pieces that might otherwise not become removed by the usual suction process?

Just a thought and over again this is not something that I accept done myself.

Peter - Hate to say information technology, but the only way to know y'all got all the hose out is to remove and disassemble the angle gear. Might as well do the TSB and re-seal it. I wouldn't permit the potential piece of hose stay in there...that would bug me, personally...I am about to do the TSB on the angle gear on my XC...the "weeping" is getting worse at 140K...

I've had enough of stuff like this get wrong in the by...so don't worry well-nigh it, just think that the dealer would take charged you hundreds of $$ to do the same thing.

I don't really like the idea of drilling into the angle gear to create the drain, even if the bit is loaded with grease to catch the metal $.25...only, when I do the TSB, I may create that bleed for the hereafter.

Thank you,

Well I've packed away the tools for the day - spoke to the local dealership and they reckon it will exist nearly $650 worth of labor. So I think I'm going to have the rally wagon towed on Monday morn and take the independent shop open it up. Cheers for all the advice - I'll written report back side by side week when she's running once more.
