I run darkside and run a 195/55/16 which works well for me, I also pull a sidecar (double wide) and pull a camping trailer(Leesure lite) and am not real happy with the look of the splines when I pulled the rear wheel off for replacemsnt (red and rusty) this time.
As the tire replacement is about every 20,000 miles what are the recomendations for lube for the splines for darkside riders?
Thanks for your recomendations
bill.

The grease should last 20K. Still advisable to do rear end services every 10K. You may not have packed enough grease in the female side of the drive last time. Also put a new oil seal on the drive shaft

Three valks since 2002: no problems using Bel Ray waterproof grease. My last Valk I sold with 155K and no problems.

Both you and 98Valk are speaking of the same item. Twd at Beemershop invented the stuff and he is supposed to call me back today with his recommendations for application. I will go with his and your recommendation. Thanks, bill. I will also let you know what he says about application. |

If u really want to know call Vincent. "TS-60 Spline Lube was formulated in collaboration with Beemershop and TS Moly" https://www.beemershop.com/product/ts-60-spline-lube.html |

a little history, there was guard dog being made by TS, so that led to the improved spline grease they sell now. "Now for some serendipity. I accidentally stumbled on the fact that a company known as TS Moly, an oilfield service company based in Houston sold a moly gear oil additive. Without fully doing my homework I mentioned this fact in a Benchwrenching column. About two weeks later I received a telephone call from a gentleman who was an executive with TS Moly. He told me that they had received several phone calls from people wishing to buy the additive. But he said that they sell the stuff in 55 gallon drums and 5 gallon pails and folks were wanting to buy pints and quarts. He asked if I thought there was a market for this among motorcyclists. I said yes and soon Guard Dog Moly Lubricants was born. It was a two or three person spin-off from TS Moly. Ben Mathes and I had several phone conversations and I met him once when he visited the Houston club rally. One of our conversations migrated to discussing spline lube and I explained what I had been mixing together. Pretty soon GD-525 Moly Grease was on the market. After a few years Ben Mathes retired and Guard Dog Moly Lubricants closed down. But the parent company, TS Moly, still sells some of the former Guard Dog products, including GD-525 Moly Grease. See: https://www.tsmoly.com/grease-c-2.htmlThey also now sell their Gear Oil additive in quarts, gallons, 5 gallon pails, and 55 gallon drums. See: https://www.tsmoly.com/additives-c-23.htmlBy the way, I had/have no interest in Guard Dog or TS Moly, except for an appreciation for a person/company that jumped in to provide a good product for BMW motorcycle owners once they heard about the need." https://forums.bmwmoa.org/threads/moly-lube-for-spline-shafts.97216/ |

I know it's late in the discussion, but which splines are you talking about? There are actually three sets of splines that need to be lubed every time:
- the splines that connect the rear wheel to the ring gear
- the splines on the rear end of the drive shaft that go into the 'pinion cup'
- the splines on the both sides of the u-joint, connecting the tranny output to the the drive shaft
For the ring-gear-to rear-wheel splines, a real thick, sticky, slightly dried out grease works good, and won't get thrown off (for example some Slick 50 from the 1980's...)
The drive shaft-to-pinion-cup is ideally lubed by the rear drive oil, but you gotta keep a good fresh oil seal on the driveshaft, and you gotta make sure the two holes that allow the oil to circulate between the pinion cup and rear drive are clear, and unplugged by dried grease. But failing that, a lot of guys just pack those splines with heavy grease, and hope for the best.
And the u-joint grease you just gotta lube the drive shaft end before putting it together, and then pull that cover off a little, and put some grease on the tranny output shaft with a flat stick, all around while the bolts are still loose. You can pull the ujoint back almost off the output shaft while the loose bolts keep it from entirely falling off the shaft.

I always have that exact same question: which splines? For the ring gear to wheel splines, I always use wheel bearing grease. It's very sticky and stays put. For the pinion cup I'm one of those pack it with grease guys. It's worked very well for me. I'm hesitant to remove the U-joint boot because one time when I did, it eventually worked loose and allowed water to get in. That washed the grease out of the pinion cup. Luckily I caught it very early and the damage was minimal, but it taught me how critically important that boot is. |
