transmission pump gasket ?

[Dan Clarke]

Hi, New guy here. I've owned and maintained my 1987 L555 since 1993. For someone who has experience working on the transmission pumps, I have a question about a repair I made. I had a bad leak and found the pump case bolts had loosened and blown the gasket between the pump case halves out. I was repairing at night for the next days work so my solution, with no replacement gasket available, was to install long lower bolts to act as supports so I could slide the housing apart for access to remove the rest of the gasket and reassemble the pump with sealer only. In 300 hours or so it doesn't leak, but I remember thinking that leaving the gasket out might have made the pump slightly noisier than before. My question is: Does the pump require the gasket thickness to establish some clearance factor that I upset by leaving it out? My service manual doesn't refer to checking end play during re-assembly. Thanks, Dan PS. I tried to form this post in easy to keep track of sentences but this editing software just runs it together into one big paragraph. Is there a way to prevent that?

To get it to post in paragraphs, you need to go into your profile and click the use http free text editor, it works for me, i also have to use internet explorer.... But it's one of those things you have to do. Also, hit preview then post that way, some times it plays up and i found this way seems to work better.
As for the pump, i don't believe it will be an issue. The rotating groups are spring loaded to provide good contact with the wear/valve plates. I don't believe the thickness of the gasket will be an issue.
