Title: Transmisson breather & filling up the bottom ? Post by: Felix/DFL on January 06, 2010, 02:21:08 am Hi,
I have got a transmission question. Is it usefull/helpfull to install a breather on the top of the trnsmission? Always wondered about that, cause when the revs get higher the little hole in the front maybe a bit to small,or? I want to drill a hole next to the starter and install a little breather like for scooters. I want to support the spot by reapair steel. Maybe somebody has a pic how he solved the problem, or is it no problem? [attachment=1] And can I use the repair steel to fill up the spots at the bottom for strenghting? A strenghting gusset for poor man ;) It is not for an all out race tranny so I will not need the welded on gussets... [attachment=2] The repair steel I am using is from Weicon and named "Titanium stick". I have made some very good results with it at my work in the prototyp pump development on alu cases, even under oil pressure. Tranny is an swing axle with LSD and some other strenghting things. Will work with an 2.2l with occasional drag use (slicks) Greetings, Felix Title: Re: Transmisson breather & filling up the bottom ? Post by: Bruce on January 06, 2010, 04:24:17 am Don't do either.
The stock breather works perfectly in a street car. The location in the nose cone is ideal because there's no hurricane of oil flying around in the nose cone. No need to fix what works fine. Adding some glue to the bottom won't give you much strength. Weld a gusset or do nothing. Title: Re: Transmisson breather & filling up the bottom ?

Not sure if it is needed for a normal 4-speed box. Ask Rancho...

However, due to the presence of 5th gear in the nose cone, it tended to push oil out of it after sustaned freeway driving. The least worse location is above the diff where it is now because the diff turns at approximately ¼ speed.
The nose cone is still the best location for a 4 speed. Title: Re: Transmisson breather & filling up the bottom ? Post by: Felix/DFL on January 07, 2010, 19:29:23 pm Hi,
thank ya both for the input! I will take care that the orig ventilationhole in the nosecone is free and not closed with liquid sealing. Greetings, Felix |
