Bel-Ray Hypoid Gear Oil in transmission

[BluesFan]

Yes, they make a primary lube and a tranny lube.

I should have real tech info in a few days.

Amsoil 20-50 in motor.
H-D-formula+ in primary.
Red line heavy shockproof in trans.

I like the way you think!

What happened to the tech-info on Bel-Ray?

[BluesFan]

I forgot.

I just sent it off in email.

(Can I blame the kidney stone?)

BluesFan,
You can blame the kidney stone,the gall stones,the Rolling Stones or the Rosetta Stone.
But who did you send the e-mail to?

[BluesFan]

'sirtech@belray.com'

nothing special there

I'm hoping my email sig will get some attention.

I'll make a call if I don't get something soon.

[BluesFan]

Got it.

Belrays 20-50 is just slightly thicker than Mobil 1.

19-21 cSt at 100C vice Mobils 1 @ 17.7

The Tranny oil is about a Hypoid 80-140

24.5*26.5 at100C Mobillube HD 85W-140 is 25.4, HD 80W-140 is 26.6

Primary is a really thin, nearly as thin as ATF.

9.0 to 10.5 cSt at 100C, ATF is 7.1 to 7.6 depending on the exact mix.

OK

ATF could be used in the primary. The lower viscosity could reduce clutch drag just like it did 40yrs ago. Based on viscosity it is too thin for a motorcycle transmission. Consequently too thin for a Sportster primary.

OK

Engine oil in the engine
Primary oil in the primary
Trans oil in the trans

Jeez thatwas hard !!!

[BluesFan]
