All the years I have been messing with Cubs and this is a new one for me. The 10hp in my 125 I rebuilt probably 15 years ago.
About a month ago while doing preservice inspection I noticed the oil dip stick tube had oil around the base. I wiggled the tube knowing there is no possible way it can be loose....not so fast there fat boy! (I’ll say it before Dag does )
Why would that tube come loose after all this time?

I've seen a few come out and have some here I think. Aren't they slightly tapered and just pressed in if I remember right? I do remember tapping a few out from the bottom side in the past. Years of heating and cooling with a cast block and steel tube that expand and contract at different rates while vibrating seems like an intelligent sounding hypothesis... or at least sounded intelligent

Probably wait until it's warm and tap it back in tight or rough up the edges with a file so it grabs better. That would be my first attempt.

I'm going to go with Kevin's "Years of... vibration". I think the tube having the weight of the dipstick end hanging out there, with the vibration, would tend to reduce the diameter (and slightly lengthen). Much like rolling Play-Doh on a table with your hand. It would be very interesting to measure your old dipstick end with a caliper vs. a new tight one. I don't see the cast block changing dimension with heating cycles, but it could slightly wear away as the dipstick starts to move.

I would likely clean everything real good and re-install with some of the Loctite green bearing sleeve retainer. I doubt it will go anywhere after that, and it will be sealed against leakage.

Mike...why would you listen to Kevin or Tom when you have me. I was in church this morning and your question really got the best of me...so I tried to explain your difficult life situation the best I could on the back of the church bulletin. Here's the way I see it.....

Dag I never looked at it like that. I guess I will the next time I get hit in the head with a brick

I never fully understood how a Turbo Encabulator works until now... Thanks Dave!

glad to help guys! I love the video of the turbo encabulator guy.

Hit it with a bigger hammer.
