So I was pressure testing an input drum to check for leaks around the shaft and low and behold, I get this tiny stream of bubbles coming from the "no man's land" where the selective washer resides. Not a line or a visible crack and it did not last the entire time I had pressure applied to the forward clutch hole. Just there about half a second then gone. Happened again when I was heating the drum up with a torch around the outside. Just a short half a second stream of bubbles then nothing. What gives?

 

Can you video?

 

It is most likely leaking around where the input shaft is pressed into the drum. Press the shaft out and reseal it with green Loctite sleeve retainer.

 

I'd love too but currently I do not have a tripod or anything that could stand in place of a third arm. I'll see if I can get someone to help.

It would have to leak at a perfect 90* angle away from the shaft to the middle of the flat area in such small bubble sizes as not to be notice. Then rise directly straight up. I'm not saying that it is impossible but I think it's close.

 

Has the shaft been pressed in/out already?
If it has been and it wasn't supported properly, there's a solid chance the drum is cracked

My recommendation would be to put this drum/shaft combo in the wash tank and get it up to 180-200 degrees then leak test it. I bet it looks terrible when warm.

 

I do not currently have a wash tank. I hand and pressure wash everything but I do have a stand up smoker. I also have brazing torches and a big weed burning torch if those help. I am pretty broke at the moment but Im doing the best I can. Ive just never heard of anything gassing out for a second and then quitting. To be clear. It did this while pressure testing and once while just heating it up with out any pressure applied.

 

Thank you all again for your suggestions

 

I forgot to ask earlier about the green loctite. I can find blue and red in my location. Is green better than red?

 

Yes, the green is for things like shafts and sleeves that have a bigger surface area.
