Correct Way to Dip Reduction Box DV10

[thompsontwins]

Hello All
Hope you are all keeping safe.
What is the correct method to measure the oil level of the reduction gearbox on a Bukh DV10. Do you screw it in, or rest it on the top of the dipstick hole. (Owned motorbikes with both options).
I have read the Owners Handbook, page 8, which is not clear, I have formed my own opinion. I do not want to expand my reasons at this time to avoid persuasion to my findings
I would like your interpretation please. Or better still, the correct answer with authority.

The manual says -

'Check oil level as mentioned below:
a. remove and wipe dipstick
b. re-insert dipstick in the pipe
c. withdraw dipstick, check oil level.'

(That is for the engine.  It then says do the same for the gearbox.)

My interpretation is that 're-insert' seems to imply you would screw it home.  

I doubt the difference is critical, but you could ensure that you do not overfill it by using it screwed in to measure against the top (maximum) mark, and make sure you do not leave it too low by using it not screwed in to measure against the bottom (minimum) mark.

Thanks for the reply. The word 'insert' isn't really helpful. I like your theory, but the reason I am being pedantic is my concern being with 0.7 pint of oil, there is not much error either way, under-filling or over-filling, either of which can be harmful. 

Page 8 paragraph 2 of the owners handbook I have says:

a. Remove oil filling plug completely

b. Unscrew and wipe dipstick

c. Reinsert dipstick in the pipe slowly

d. unscrew dipstick and check oil level check oil (between marks blah blah)

e screw in oil filling plug.

This suggests that between action c and d, the dipstick must have been screwed in, in order to unscrew it again. So it looks like it must be dipped by screwing in, and not just inserted resting on the top of the dipstick hole. Would have been helpful to say screw in (like at e) instead of insert.

Hi Paul. Given the additional wording in the version of the manual that you have, I think you can be certain that the dipstick should be screwed in to measure.
