Priority 600 - Pinion gear box - oil viscosity mystery solved by oil testing at BlackStone Labs

Описание: Greetings,

In this film, we talk about what type of oil Pinion sells for its gearbox based on the analysis of a pinion gearbox of oil sample after 1 year and 2,500 miles of use.

The oil tested at the 75w-80w range.

Testing Process:    • Oil Analysis Start To Finish: Part 3   Cost to test at blackstone labs was ~$35

Takeaways:
a. There is no scientific reason you need to buy gear oil from Pinion. Buying 75w-90 synthetic gear oil will have the same properties.
b. The oil had a fair about of material in it. For that reason, I will change it every 4-6 months instead of every 12 months.
c. You do not need to buy the Pinion gearbox oil changing kit - oil every time you need an oil change. You can buy the items below and do this yourself with your own kit. Just make sure to measure 60ml of oil for the gearbox.

The oil kit from Pinion is $40. YOu can buy 1l of oil on Amz for $ 15 USD which is enough oil for 16 oil changes!

Materials you can use that are cheaper and just as good as what you will buy from Pinion:

75w-90 wight synthetic oil https://tinyurl.com/2w42mz2k
100ml Plastic Graduated Cylinder Beaker - 100ml Science Measuring Test Tube Flask, 2-Sided Marking - Black and Raised Graduation Lines, Pour Spout https://tinyurl.com/mr2w3y7u

If you like the pinion kit but what different oil. Buy the pinion kit one time and different oil the next time.

BUCK: This sample's viscosity fits the ranges of 75W and 80W gear lube. We found a lot of wear metal in the spectral results, but we're not sure if it's a concern or not. We don't have a lot of experience with Pinion gear boxes (this seems to be the first we've ever seen, but the high metals can be partly related to wear-in since this is the factory oil. The water contamination and high insolubles (solids) might have contributed to the high metals - excess solids can tum oil abrasive. If the bike is running well, check back on metals in 2,500 miles for an update.
