Kanzaki KM35P - Dip stick w/o marks?

[Chuteman]

I've checked multiple times in all sorts of light.
Instead of the usual H & L marks on the transmission dip stick
as described by others & the manual (general)
There is only one circular line very close to the bottom of the
dipstick.

Any hints on how to determine proper level? Or if no leaks, just drain &
fill to spec?

Thanks in advance

BTW - this gearbox takes SAE 20 or 30 HD oil

I believe the oil should be up to (but not above) the circular mark. The dipstick is only as long as it needs to be to reach the oil. This confused me too, but my mechanically-experienced father reckoned that was probably about the right amount for a splash-lubricated gearbox.

Humm, makes sense

Pete:
Thanks for response.......
That mark is very low on the stick and mine had oil on the stick but since I was expecting to find 2 marks I never just focused on where the oil sat compared to circular mark......but I will go check now.

Mechanically-experienced Father - great resource.......I know because I lost mine way too early.

Best & thanks again........off to check & not (hopefully) break the stick which seems generates more than a few comments

Looks Good

Pete:
Based on what You passed along - it looks fine.......although I still say
it takes some getting used to.......especially when all the references
are for 2 lines and all the Yanmar/gearbox combos do not give specific
details on the KM35P dipstick

Thanks again to You & Dad

Cheers

Might be best to wait for some corroboration from someone else on this thread. I'm just saying what we did, not holding myself out as expert.

Surely if the dipstick has only a single mark that is the level to which the gear box is filled. Gearboxes, unlike engines do not use oil, so there is no call for a minimum mark. Once filled the oil should remain at that level unless of course it leaks ... but then top it up to the mark again and cure the leak as soon as practicable.

Only one "mark" on my car gearboxes and outboard engine gear boxes and that is the bottom of the filler hole!

Makes Sense

VicS:
All your points are well taken.
Just a "rookie" making sure I understand completely especially when the manual references 2 marks.
I'm much more familiar with auto side........where your finger was the dipstick
on the gear box......or just enough so it was weeping out the side fill hole
Just being careful and conservative.......like to keep the parts I have
in good working order

Thanks for reply

Is the dip-stick threaded? If so, it should be resting on the theads, not screwed home, otherwise the level indication will be wrong.
Certainly applies to Hurth boxes, and, from memory, to Yanmar as well.

Yep, that's definitely the way to read Yanmar ones, or so it says in the manual.

(Just confirming for anyone else that might stumble across this thread later.)

+1 and +1 on the last two posts. And if you end up needing to know how to read it, just roll it on a piece of paper towel, it'll be clear where the liquid mark is since the new oil will be very clear.

I could have sworn that I posted this before.....

The Yanmar "GM Series Operation Manual" that I have which covers the KM2P/KM3V/KM3P boxes as fitted to 2GM20/3GM30 engines says:"...Insert the dipstick fully to check the level.

I also have a manual for the Yanmar KBW10 (developed with Hurth) which says that the dipstick should rest on the top of the oil filler hole when checking the level. (Also that the groove indicates the maximum oil level and the end of the dipstick is the minimum.)

Ergo: It depends on the box - RTFM
