Transmission Peep Hole
Hello Guys,
Do you know if there is a peep hole in the transmission so that I can have a look inside? I need to replace my thrust bearing but a friend of mine said if there is a peep hole I can "spray grease onto the bearing with out taking it out. The idiot that replaced my clutch did not grease it before putting it back
I need grease on the thrust
I need grease on the thrust bearing, the one thats located on the pin that goes into the clutch. The reason I want to spray grease on there is because the idiot didnt do it the first time. My thinking is that I want to get a sprayable grease (in a can) and attach a longer hose and get right by the bearing spraying it into the balls without taking the whole bellhousing/transmission case apart to get in there. Is it possible?
That is the clutch release bearing.
The bearing you're referring to is called the "clutch release" bearing (Mitsubishi's name for it) and it is also commonly known as the throw-out bearing - it's a circular bearing with a large center hole through which the transmission input shaft passes. The clutch release bearing is attached to the clutch release fork, and when the clutch pedal is depressed the release fork moves so that the release bearing depresses the fingers on the clutch cover (Mitsubishis's name for it) disengaging the clutch.
The clutch release bearing is a "greased for life" shielded bearing - it is greased at the factory and fitted with shields to prevent the grease from becoming contaminated by the dust produced as the clutch's friction linings wear - it is not a serviceable bearing from the point of view that it can be cleaned and greased - you can't see the balls and you can't replenish the grease without prying the shields out which will destroy them, rendering the bearing unsuitable for further use.
Few people would consider opening & greasing a clutch release bearing - maybe if were in a last resort, "get you home" scenario - but certainly not with the intent of long term use - especially given the cost of the bearing and the labor involved - which is also the reason most of us simply replace the bearing when we replace the clutch.
Your only real option is to purchase a new bearing, drop the transmission and replace it - spraying grease at it is not going to work, and as was mentioned previously - you run risk of contaminating the clutch linings.

Hello,
110% agree, you cannot grease that bearing. It is a seal unit. your idea of a longer plastic pipe to grease it will wreck you new cluch, and will result in a expensive repair: time+bearing+cluch and you will feel very silly! But the person that replaced the cluch should have replaced it, you might be able to do a claim.
All the best,

One word - DON'T
I have no idea if there is a peep hole - and by the way, you need a peep hole in the bellhousing, not in the transmission - but there is no way you're going to get grease inside the throwout (or release) bearing (not the thrust bearing - that is something else), where it needs to be, by spraying it at the bearing, and the last thing you want to be doing is spraying grease into a bellhousing with a new clutch and risk contaminating the linings.
