well done!
i forgot that chart

it's a guess anyway since we don't know exactly temps inside the tranny... and what kind of additives we are facing...

it can help to grasp the idea though

and in addition I think is between the abilities of this forum... the skill and competences to verify the op temps inside the tranny at the throwout bearing point...
if some expert can chime in...

I'll put it on my list to install a gauge on the primary.
If I can find a used derby cover to drill a hole in, that'd do it.

edit:
Just bought a used cover on Ebay.
Will get numbers when I get all together.

excellent
power to search knowledge is the plus of this forum

OK.
I updated the FAG upgrade information in the Pedia to include specs for both the 7200-B-TVP and 7200-B-JP bearings.
There are also links there to the two PDFs the information came from.
Thank you for the suggestion.

Here is the link to the page.

Hippysmack,
Thank you! Always excellent and upgraded info on Sportsterpedia. This forum is so far ahead of any other forum I've ever seen on any vehicle, motorcycle or not. I'm constantly learning how much I don't know and why I'm usually wrong. Thanks for your efforts and attention to detail.

Hippysmack · #86 22nd September 2020

Your welcome and thank you and all the XLF members for their contributions for which the Sportsterpedia would not be possible without.
I'm learning something new everyday.
And I'm usually wrong twice a day. As long as you keep a decent average I guess.

It would be interesting to know the correlation between the temperatures between the oil tank, the crankcase, the primary and if possible, the two heads. The only gauge I have for reference is my H-D oil tank cap/dipstick with the analog thermometer. I've tested it for accuracy by dipping it into boiling water and got 212 degrees F.

Hippysmack · #88 22nd September 2020

The infrareds are pretty cheap at Harbor Freight. Just point and click.
There are mixed reviews on accuracy of them.
But I matched it pretty close to my dipstick thermometer.
Did heat cycles with it and I didn't blow anything up.
If you're looking for pinpoint precision, it's not the best choice.
You can crook it sideways jist a bit or mix distances apart from the target and get a different reading.
But if you take multiple readings back to back, you get an average.

I'll pop a hole in the spare derby cover and place an actual gauge there.

Stick with OEM bearing. I have replaced mine twice already. Keeping your bike clutched at red lights is a real good way to wear these out.

sure a thing to have as a spare when you put your hands inside the derby cover
either you have installed OEM6200 or angular 7200B TVP... with polyammide cage...
better safe than sorry...
price of the bearing is low... so you can replace it like other things that worn out overtime...
let us say every 40 - 50k kms?...
you do the same for many other parts of your bike... so why not for this?

then if you are lucky enough to find a original FAG7200B JP with sheet metal cage... IMO you can forget about it...
