Harley Twin Cam engine problems

I believe that most of the issues with Harleys are the owners getting in above their heads and trying to do work they really shouldn't be doing and then blaming Harley or some aftermarket part maker for burning up their engine because they installed the product wrong And, what makes this runout situation worse? Harley-Davidson used to keep the crankshaft runout balanced to about 0.003″ but in the year 2011 to the current Twin-Cam engines the crankshafts leave the factory to allow as much as 0.012″ runout which is so huge you can't even install a gear drive kit

The cam chain tensioners is mostly a maintenance issue. The bearings well, Harley has this big theory that the ina bearings give better service. They don't, they had the same problem with evo's using the ina bearing. The torringtons are rated at a heavier load capacity than the ina bearings. It comes down to cost Includes all Twin Cam engines, from the Twin Ca... A frank discussion of the inherent flaws with the Harley Twin Cam engine, produced since 1999 to the present

It's not difficult to check. Will it be a problem if you don't take care of it? Yes. It's like any other machine, they need preventative maintenance. If you let it go then you're asking for bigger problems. A buddy of mine has an 2001 TC with no problems, mine is an '06 and my engine has been trouble free. Tensioner has minor wear on it Were there any problems with twin cam engines that I should be aware of? Someone told me the lifters suck and are foreign made. Was told they should be replaced.

Harley Davidson Twin Cam Chain Tensioner Problems 1999-200

  1. The new design runs so cool, Harley's engineers were able to crank compression as high as 10.5:1; add that to an 8-valve engine with a 55mm throttle body flowing 50% more air than the Twin Cam, and they were able to crank a lot more power out of the new engine
  2. While everyone experiences engine problems eventually, most would agree that they don't want this to happen while riding their Harley. The 2005 Softail Deluxe's twin-cam engine problem, is something you'll want to avoid, according to many reviewers on the web
  3. One of the most central and most commonly overlooked issues with Harley Davidson bikes lies within their Twin Cam Engines, specifically, with the design aspect of the cam chain system. The plastic shoes rest on the cam chains and actually wear out over time. Talk about a design flaw
  4. If the engine is under warranty, you may be lucky enough to get it replaced. However, the problem is waiting to zap you again, because a new engine usually includes the same weaknesses as the damaged engine. Oddly enough, not all Twin Cam cranks shift out of true and result in catastrophic engine damage. The problem is typically hit and miss
  5. Newer Twin-Cam engines also have oil pump problems if ridden hard or the engine has been modified. The problem is not the oil pump's pressure side, but the suction evacuation side become overwhelmed and can not remove the oil fast enough from the crankcase

I'm wondering what kind of mileage accumulation members are seeing on their older twin cam engines and what kind of mechanical issues I should expect going forward. I have been inside the cam chest a couple of times for maintenance, including tensioner shoe replacement, servicing the oil pump, and cam bearing replacement, and I don't have a problem doing that Perhaps the biggest unforeseen problem with the brilliant new Twin Cam 88 was that it would not fit in the Softail bikes without a substantial redesign of the bike itself. The Softail frame was a tighter fit and did not provide room to rubber mount the motor like the Dyna and touring models do, which was considered a necessity due to the larger pistons and increased vibration The Twin Cam was designed to make factory assembly easier (and of course cheaper) at the cost of most of it being disposable rather than rebuildable. And then there is that heat issue. So if the only thing gained was power, the TC is a total fail. The EVO had plenty for what it went into One of the most revolutionary systems within Harley Davidson's 88 and. 88B twin cam engines is the dual coil system. This ensures that no. spark is wasted, and is another noticeable improvement over the previous. models of engine.

As the engine rpm rises, the vibration becomes far less intrusive and the genius of Harley's mounting system comes into play, as the motorcycles are very smooth and comfortable at highway speeds These camshafts then align easily with other engine components with their two cam lobes. A chain, that is silent, drives the camshafts' operation. Although the lack of noise from the chain can be nice, this chain causes timing issues. To correct the problem, many Harley owners put in after-market camshaft drives See similar items $61.44 Buy It Now, $25.16 Shipping Estimate, Click to see shipping cost, eBay Money Back Guarantee.

Hopefully this will offer some insight into what can cause some motors to need a rebuild at 35K miles and other identical engines go 100K miles with few problems Cooling the cylinder heads with liquid has no effect on service interval: Harleys with equivalent Twin-Cooled and standard engines require service after the first 1,000 miles, and 5,000 miles thereafter. Incidentally, the new engines use the same coolant blend as the V-Rod, a 50/50 premix that uses long life coolant Feuling Vented Dipstick for Harley Twin Cam & M8 Touring Models. The Feuling Vented Dipstick can help motorcycles that experience what is called oil blow by. This is when oil is pushed out through the air intake. This problem is not only frustrating, it creates an oily mess and can even blow out oil onto the rider if the problem is severe

Today, Harley Davidson gives the rationale by stating that a liquid-cooled engine was the only possible evolution of its engine, making the following statement: If you started in 1909 with the very first Harley-Davidson V-Twin engine and worked your way up through every engine, every innovation, every improvement, every ride, every durability test in all those years and countless miles. New cam chain tensioners; Any other parts that are unserviceable will be replaced at extra cost.

Den titeln går till Flathead-motorn, det vill säga sidventilaren på 750 kubikcentimeter The computer determines the engine temperature. If the engine is cold, then the fuel number is adjusted up by a pre-determined percentage. For example when the engine temperature is a 30 degrees F, the computer knows the engine is cold and needs more fuel, just like a choke on a carburetor According to Harley-Davidson, there's a 75 percent reduction in primary vibration at idle, so the motor will be dancing considerably less at stops. 7. Liquid cooling keeps the rider cooler. With.

The Harley-Davidson Engine Explained New Harley-Davidson engine designs arrive about every 15 years. Since 1936 engine designs released by Harley represented classic forms that the Big Twin has taken: Knucklehead, Panhead, Shovelhead, Evolution, Twin Cam, and the very large single-cam engines. A Harley engine is a two-cylinder piston engine 1999 - 2016 Twin Cam. The Twin Cam engine delivered more torque and power than the Evolution model and was originally available as a carburetor or with fuel injection. Problems with oil circulation in the Evolution engine prompted Harley-Davidson to equip the Twin Cam with a more powerful internal twin engine oil pump The heavy gauge steel construction and durable black powder coat make the Lowbrow Twin Cam A Motor Stand simple to use and stand up to use and abuse. Perfect for cradling your Twin Cam A motor whilst you work on your trusty steed. Twin Cam A motors are installed on a rubber mount in the frame, found on Dyna, Road King, and Electra. An easy way to spot an A motor is to look at the front motor.

One of the most endearing features of a Harley Davidson ® motorcycle is that throbbing V-Twin engine. They've been making them since 1909, and the 2008-2011 Harley Davidson Twin Cam 96 V-Twin and 2009-2015 Harley Davidson Twin Cam 103 V-Twin, are two of the most advanced potato guns to date The TC96B doesn't feel as strong or as willing to rev--Harley claims 90 pound-feet of torque at 2750 rpm--and it's not quite as smooth as the rubber-mounted 96 either I still like the Evolution engine for it's simplicity and longevity. My Twin Cams have Andrews gear drives in the chest, seem to work real well although they're noisier than stock chain drives. Rumor has it that this is the reason the factory didn't gear drive the twin cam. Not like they didn't have nearly 90 years of experience in gear drives.. The Axtell Twin cam iron liner for example is 280% thicker than the iron liner in the factory cylinder. A well designed all-aluminum cylinder will grow uniformly with minimal twisting and distortion, and will offer excellent heat dissipation and long life

Well Harley had a bad reputation for motors that had always broken.hence the wrench one dayride the next day..reputation so in 1981 the came out out with what was supposed to do the best motor Harley had ever made....breakthrough stuff like aluminum heads and block.this motor ran until 2000 and the birth of the twin cam engines.....your 1340 will last about 70,000 mile Forums > General Tech Harley Davidson > Engine, Fuel and Exhaust > adjusting valves twin cam 88. The twin cam has hydraulic lifters and the old sporty was solid lifters. Now my next problem is the top end seems to be running hot any ideas why? Fearless1, Oct 22,. Twin-Engine: The earlier twin-engines were called V-Twins, which were mainly produced for models prior to 1984. These engines are distinguished by their unique names such as Knucklehead, Panhead, and Shovelhead. Things changed with the introduction of Evolution in 1984, which was a solid 1,340cc engine. Subsequent upgrades were made by introducing Twin-Cam and Milwaukee-Eight Looking at the differences between the new Milwaukee 8 Engine from Harley Davidson with the old Twin Cam, you begin to see just where the improvements where HD focused in on. Lemmy at Revzilla broke down all the improvements on this here. I'm still road testing my new bike, so I'll need a few more miles to get a good opinion formed on it

Apparently the single most important lesson to learn about the MGA Twin Cam engine was not figured out by the factory until after this model had ceased production. The engine had been plagued by burned pistons, quite mysterious at the time You'll need some engine oil. The manual recommends no more than 3.3 Litres (3.5 Quarts) to fill the oil tank. I've found that around 2.5 Litres (2.65 Quarts) will fill the tank to the proper level on my '05 Softail. There is a myriad on engine oils out there on the market and choosing an oil for your Harley is a bit of a minefield As one of the youngest people to ever reach Harley-Davidson's Master Technician level, Marty Smestad of Capitol Speed Shop knows a thing or two about V-Twin work.
