Daft Question

[dsc652]

Had the upper gearbox of my 290 drive completely refurbished recently.

Can you tell me what size / type of spanner should be used on the two side studs which are recessed into the side of the mid section casting ?

Some seem to see this as a routine removal / replacement to do the bellows etc - is it ?

How do I ensure an airtight seal - dont want water getting in and wrecking the drive.

Many thanks,

Doug

Takes a 9/16" wrench on the 2 nuts.
Pulling the upper gear box is a LOT easier than pulling the drive. Especially when replacing the bellows. I replaced my bellows yearly when I lived in Alaska, simply because of barnicales on the bellows. I didn't want to be fixing expensive things due to sharp little creatures cutting holes in a part that only costs 65 bucks. Takes a couple of orings between the upper and intermediate, but nothing major.
Install the new bellows per the instructions, and they don't leak. DO NOT over-tighten the clamps, that will cause a leak, and make sure they are positioned correctly (also in the instructions that come with the OEM bellows).
While that may sound like a lot of work, after the first time and you see what is going on, it's a 30 minute job to change the gear lube and replace the bellows. No big deal.

Hi Don,

Many thanks for your response.

Have tried an open ender on these, but not sure if I have them tight enough.

Is there a special tool, or a special ring spanner ?

I see in the manual that the VP guy in the picture seems to be using some sort of small box headed spanner ?

Should I have put any sealant on the mating surfaces ?

Regards,


Doug
