Dang leaks

[fdinger]

I have a few things in mind to use , but I thought I would ask before I try it
have some of you had the big hydro line leak at the connection under the
rear end, and what did you do to stop it ? I pulled the rear out of the 129 to replace the cork gasket and the line on it had a connection joint at the bend
" don't know if this was org." but after I put it back together the darn thing leaks at the joint, tried to tighten it still leaks a lil, compresion fitting,
2nd the 149 I'm working on now " just waiting for the motor to get back "
Changed the rearend oil and the darn rear houseing plate leaked after the in
install and retighten the bolts to 40# still leaks , so it's gotta come off and get cleaned up and RTVed , but also the big hydro line on the bottom is dripping at the connection going into the houseing. What have some of you guys done to stop the leaks. I was thinking thread tape or dope or permatex or is their something better ??

Did you use a NEW rear cover gasket and clean the gasket surfaces on both pieces first? RTV should not be necessary to prevent leaks. I have NEVER used RTV in any rear and have never had a leak. See if the sealing ring on the compression fitting is screwed up. If that's bad, you'll probably have to replace the suction line.

"retighten the bolts to 40#"...????...

40# is a force, not a torque. Do you mean 40 in.-lbs. or 40 ft.-lbs.? 40 in.-lbs. isn't enough.

On the rear cover plate, normally the problem with a leak when replacing the gasket is some PO has overtightened the bolts in the cover and put a dimple in the metal around the bolt holes.

You need to put a straight edge on the cover and if you see any indentations, you will need to flatten out the plate.

Sometimes people will put in a bolt too long for the housing on the rear plate and the bolt will bottom out before the correct pressure is placed on the gasket. You can damage the casing if your bolt is too long and too much pressure is applied.

Yup, just what "RChristensen" said... Also check to make sure that you put the three longer bolts in the bottom holes and don't forget to put the hitch on, or those bolts will be to long and will probably break the holes out in the housing. Just as "Matt G." said, I've never used any sealer on a rear end and have never had a problem.

All the bolts on the 149 are right and yes it was cleaned before replaceing and your right I didn't have a leak or problem on the 129 when I did it few weeks ago. It's coming off so will check for straightness but it's going back on with a thin layer of RTV because I'm not going to pull it off again, As for the suction liine will have to see if the connection on the 129 got a ding when installed but the 149 is leaking at the fitting that goes into the houseing I thought I could use thread tape on this one.

Thanks guys

If you're going to take it off again in the near future, I'd just use some rtv. That's all I use anymore because one tube will last several fluid changes and it's not worth the 40 mile round trip to the dealer for me.
