While moving sites in Goshen in June, someone mentioned they heard a clunk in one of my wheels. Nancy heard it more recently. Then I ran into Pat Poole who told me about a clunk he had and what it was. For him, it was a broken Kodiak Grease Cap on one of his brake hubs. Like me, Pat also has 8k Kodiak disc brakes. MORryde sent him a replacement set of Oil Caps and he recently had them replaced at a shop in Oregon - about a 1 hour job.
I spoke to MORryde about my clunk and they agreed to send me a set of 4 new Oil Caps. The old ones were white plastic (ROTOR/HUB-8-WHTPCAP), so I assume they were PVC. The new ones are clear Polycarbonate - aka Lexan (ROTOR/HUB-8-PCAP) - Oil Caps.
Yesterday, at the Wisconsin rally, with an impact wrench borrowed from Dave Hromek (cookie) and the assistance of LevelUp to lift the coach off the ground a inch, Dave helped me remove two tires before he had to take off, then Walter West helped me remove the other two tires.
We did one side at a time. Probably took a half hour per side - 1 hour in total. Once the tire/wheel was off, I removed the broken cap, rubber o-ring and any other bits from the wheel center cap, then with a finger, backed out the broken grease cap threaded part from the brake hub spindle and added the new clear oil caps. Note that the 8k grease or oil caps take a 2-3/16” socket. I didn’t have one of those so I snugged them up with Channel Locks. 20 - 30 ft lbs is the spec.
Below are a couple of pictures and here's a link to a gallery with all of them.
