Yanmar dipstick thread broken

[Caladh]

Could this be epoxied and make a decent repair, bearing in mind the force to do up and undo ?

I can’t answer your question but simply add that this is a common failure and stupidly expensive to replace. I am aware that there is a firm that makes steel replacement equivalents that don’t break though I haven’t yet personally acquired one.

Depends on what type of plastic its made of.

If its can be melted I would try to plastic weld it by adding more plastic to strengthen it

There was a steel replacement on one of the gear boxes on my previous boat, but I'm afraid I have no idea who made or supplied it.

I had one of those & it would not reach the oil, so I had to make a longer one.

Could you push the part back up, push a washer on and then a split pin or roll pin in the hole on the stick. This assumes that the hole is the whole way through the dip stick.

Is that $85 that I can see in the bottom right hand side?

 

[rogerthebodger]

Just measure the thread and see if it corresponds to a standard thread and make a new dipstick using that thread

Yes it is, but the replacement Yanmar version is a similar price and regularly breaks as has the OP’s.

With my post I assumed that it was a plastic rib so just pushed it, like many cars.

I'd be reluctant to use any glues / plastic weld ... if that threaded part breaks off again when you try to remove - then you have a problem.

Earlier suggestion to glue AND pin - would be better idea and could work.

Don't forget there is a breather channel up the middle of the fipstick

Yes I had thought about the breather hole and if I glued/epoxied would block it. I like the pin thru the tube suggestion, but will probably bite the bullet for £50 ish. Thanks all

The Cariblue alloy replacements are excellent

They are a complete pita. I've tried various glueing options but in the end, the answer is new.

Boats are supposed to have stupid money spent on them.

Oh, by the way, when the cone drives wear so they won't engage anymore coz the gear lever has been put in astern counter to makers instructions, a new gearbox is proper money.....

Which is exactly my pain for this season.....new gearbox, ouch.

I've broken one and learned my lesson. The trick is not to use force with it. I'm told it doesn't need it.

 

[tudorsailor]

It has broken once. The next will break at some point, so buy two so you have one ready for next time

 

[cherod]

Buy s used one
