Minnesota Mom of Two Diagnosed with Cancer Hours After Husband Dies From ALS: 'I'm Not Ready to Give Into It'. I Love Harley- Davidson, But You Must Know This. Here is the ignored elephant in the corner. This is a statement of fact, not a bunch of wild guesses. ![]() It’s a very serious one that is enough to alarm you. Our objective today is to educate, and we are also going to outline some ways to fight back.
Harley has made some changes in later model bikes, but even with the new hydraulic tensioning system, it is not a true fix. If not caught soon enough, this can be so bad that the entire engine can be destroyed; cams, pistons, crankshaft and even engine cases broken. In the most severe cases, as the spring loaded cam chain follower fails it shreds plastic material that fouls the rotary gear oil pump cutting off oil flow to the engine that can cause sudden catastrophic engine failure and destruction. This is not a likely situation, but a realistic possibility. Are the 2. 00. 7 and newer, updated Twin- Cam engines immune? If you can’t afford to install the gear drive system, then you need to disassemble and inspect the inner and outer shoes every 1. Dealers will tell you it is a failed maintenance issue unless you take the steps we suggest. You won’t even get a straight, honest answer from Harley dealers regarding this engine defect. Disturbed and curious, I read a number of different service manuals, and while the drawing of what is good and bad with the cam tensioner shoes is published, there is no inspection interval listed. This leads me to believe Mother Harley knows a problem exists and Harley- Davidson dealers are actively not giving straight answers to customers. How can they not have published inspection intervals? The only mention of this possible failure is in the troubleshooting guide under “Valve train noise.” You will not hear any rubbing sounds or receive any indications the cam follower has failed even if you have quiet stock exhaust pipes on the bike. This is an issue that nobody wants to talk about, but is a real threat to your pocket book. OK, now that we have ruffled everybody’s feathers, how can we combat this? S& S has truly been visionary in solving this issue. They had the foresight to develop a gear drive system to combat this very issue. It is my opinion, that all Twin Cam engines should have this conversion done, so you can rest easy on your higher mileage TC engines. The gear drive replacement is an excellent and the only true bulletproof solution. As an alternative to gear drive, our only choice would be periodic tensioner shoe inspection. While not outlined in any Harley Service manual I’ve seen, looking at them and replacing as needed should be done every 1. There are nice pictures of what to look for, but no recommended inspection interval. If you decide not to go gear drive, this is emphatically recommended. This periodic inspection can make any future warranty claim valid. On earlier engines, an update to the later style hydraulic tensioners will relive pressures and delay required service, but periodic inspection is still recommended. Check things out before this happens to you. One way to help understand what may be happening inside your engine is to cut apart your oil filter at each oil change. Look through the pleats for any metallic or plastic debris. If you see junk, it’s time for your engine to come apart. You may be able to save your engine’s life by doing this. Another thing to consider is better oils. Today’s better performing premium oils can delay the destruction. Here, synthetics, such as the Bel- Ray Synthetic (part number 9. Revtech MTP Synthetic (part number 7. Lucas Synthetic (part number 9. As we have a decent oil filtration system in our TC engines, a way to help the filter is to apply a magnet such as PN 7. This will help trap any metallic grunge that may be floating in our oil. It has been my objective here to educate, not to assassinate the dealer network. Being forewarned is to be forearmed. As we pointed out earlier, if you have a higher mileage TC, you might want to inspect the tensioners before they bite you.
