G5 Transmission Oil question
« on: June 28, 2020, 12:28:42 PM »
Hi there,
Wondering what people recommend for oil on the G5 transmission and rear drive. I am asking because I am currently running 80/90 and it seems to be seeping from multiple spots. I thought maybe a different oil could help this? Also am wondering what people think of adding a transmission seal aid to the oil? Any harm in trying this? I realize that it’s a 40year old transmission and probably could use new seals but thought I would try the easy stuff first.

I had  the  first  1978 G5 in the USA
I was the second owner. First owner was Charlie. Pineiro who lived on Seagar  Ave in the Bronx, near the Whitestone  Bridge.
 
Charile knew Berliner  the importer at the time personally and he bought it right out of tbe warehouse. I bought in in 1979 with 35000 mile on the odo.

If you have the original brochure of the G5 it would have a G5 with a person standing next to it standing under a sto e bridge wearing a light brown leather coat .
The story Charlie told me is he bought the bike so fast they didn't have time to take pictures for the brochure so he rode it out to that park somewhere north of the city (NYC) that was frequently with motorcyclists on the weekend and they took the pictures, however the person in the picture is not me just a point of Interest.

Now to get back to your question on gear oil.

At the time in 1979 I switched  the entire bike over to synthetic oils , transmission and rear differential .
I was using Mobil 1 75/90 synthetic in trans and rear diff, the engine I was using 20-50 Klotz synthetic oil .
I sold the bike the odometer showed 165000 miles but it was more than that ,
I would say 200,000 plus would be a fair guess, did the transmission leak yes, my leak happened to be from the throwout bearing o-ring had collapsed and the shift Rod had to funnel shaped cones on the shaft to prevent oil leaking i to the clutch,that was later changed over to the O-ring version of the seal and never had any more leaks.

    Ok, I will bite (oil thread, kind of). Rear end gets 80/90 Generic Dino and transmission gets 80/140 generic Dino because it tends to whiny when hot on the thinner stuff. All a personal preference.

Thanks for the info guys. I’ll try an 85/140. I haven’t had the bike running long so personal preference is still building. I appreciate the direction. Tomb, that’s really neat with your G5. Ive heard great things about the bike and love it so far.

Yes, thats the picture.

Damn fine bike , and Charlie Pinerio was a great friend to all, sadly he has passed on for the long ride above.
