Straight-six gearbox oil top-up?

[ResinRocket]

I'd like to check the gearbox oil level and top it up if necessary - where is the filler plug located? I assume it's on the side somewhere and the fill level is just below the hole!

It's a 1600 straight six engine with 4-speed manual gearbox (no overdrive). I'm unsure of the year as it's fitted in my Bond Equipe GT4S (not original engine)

Also, is EP80/90 oil OK?

Apologies for asking rather basic questions, I've not managed to get a workshop manual for it yet, but I'm taking advantage of having the time to fix and sort out various things on the car at the moment. :)

BB,
(Please, we're on real-name terms here!)

Filler is on the right hand side of the gear-box itself.  A square ended conical thread bolt.
Access is not easy, unless you take the gearbox cover off.   Many will cut a hole on the cover and make a lid of some sort, so that access is made simpler and maintenance easier.   Pic below of my Vitesse cover with an access hole.

EP 80/90 should be fine, but make sure that it is "GL-4", as the GL-5 spec. includes  sulphur-based additives which can attack the "yellow metal" components, synchrto rings etc in the gear train.

You really need a WSM, if only to answer this sort of Q straight away.  If you can't find a WSM for the Bond, then the Haynes Vitesse/GT6 one will cover all the mechanical bits.

The acces port is the oval one, secured with spire clips and ST screws.

Thankyou John! The gearbox cover is off already as I have been removing the speedo cable to replace it. To be honest that's why I wanted to top up the fluid, as I mistakenly removed the speedo drive gear and a bit of oil was lost. Not a lot, but I figured I'd top it up. The oil looked nice and clean anyway! Speedo cable is now removed and speedo drive back where it should be.

I'll be getting a workshop manual posted to me but with it being Christmas it's not going to be here for a while yet.

Thanks again for your advice,

Dean
