![]() That speed is higher on a webcam 142 than a stock bus cam. Each cam has an engine speed that it works best at. Like the person pushing, if the push is out of time it slows the person on the swing. It has the equal of timing, length and strength that it allows the air to move in and out of the cylinder. Without getting into a lengthy discussion, camshaft timing allows what is effectively the same as one person pushing another on a swing. The "stock" webcam 142 for example is based on the "stock" 2.0L GA D-jet 914 / 912 95 - 100 HP engine instead of the "stock" 70 HP GD or GE bus engines. Also - each camshaft had a series of gears + to - sizes for each grind. ![]() They did not look at optimal HP and performance but rather torque, reliability, smog and fuel economy. VW tuned the camshafts to the engine needs. Location: Citrus Heights CA (Near Sacramento) Thanks for the picture goes to vwestyman and his Wild Westerner thread. I imagine this is one of the things I can expect if I use my camshaft that feels like it has some play in the gear-to-camshaft joint: Would a stock camshaft be so different or troublesome for an automatic transmission? So I have contacted three possible vendors.and it's looking good for a stock cam at this point, but I am curious about the significance of the Automatic versus Manual transmission application.Īssuming mine is meant for an automatic as so indicated by the two cast rings (See Bentley notation above, along with points A in picture), why is this important? The UGLY aftermarket cam with the GIANT B is an aftermarket cam from who knows where and as Randy mentioned a candidate for a paperweightĪnd the camshaft gear is likely a magnesium gear, Volkswagen P/N 021.109.111BĪnyone recommend a recent source for correct cam and lifter replacement?įor type 4?.go to either Webcam or the type 4 store. Posted: Sun 8:57 pm Post subject: type 2 camshafts and liftersĪctually Most all the cam grinders WANT the cores with the GEAR attachedĪnd the lifters are Solids not Hydraulic (NO keeper spring inside end of lifter) Tcash, very nice.once again jumping in with good links I just looked again in the Big Green Book.and no, they don't really look externally like the hydraulic lifter shown.Īny recommendation for replacement supplier and part numbers? This engine will be mated up to an 003 automatic transmission. but I haven't gone too far investigating. I thought those might have been hydraulic liters because they come apart into a few pieces. Location: California's Hot and Smoggy Central Valley RayĪ dead Type 4 camshaft makes a great paper towel holder on the workbench. It looks like the lash between crank and cam gear was excessive. ![]() There should be virtually no wear marks to the crank gear.unless this engine was just full of grit forever and it wore things down.Ĭheck the inside of the oil pump for wear. 010".its from the wire pushrod tube keeper and the rod is just fine. If the wear on the pushrod was just a single thin line about 2" from the rocker arm end and its not any deeper than about. ![]() Also.pretty much religion with me.cams in all used engines that I an going through with an eye to rebuild.I scrap the cam and lifters except for the gear unless its a magnesium gear.then scrap it too.Īre you sure those are hydraulics? It may just be the photo detail but they look like solids.
