What is the best procedure to check/adjust valve clearances? This engine is a perkins diesel inside of a cat generator. I know that he exhaust valve is .018 and the intake valve is .008.
take off the valve cover(s) and your will see the valves. you will need to turn the crank so it will be top dead center(there should be a mark on the crank and a mark on the engine for checking the clearances. then whatever ever cylinder you are checking the vavles on are top dead center, use the feeler guage and make your adjustments.
Adam S, you're both right and wrong as far as needing to adjust valves. I changed 2 shims in 100,000 miles on my Kawasaki KZ1000, but my 1300 Kaw touring bike with nearly identical valve train needs checking and adjuuting every 6,000 miles or so. Go figure. Kneedragger, since your bike requires manual adjustment, you're valve train is either going to have a rockerarm type system with threaded screws and locknuts (easy) or use shims of various thicknesses to adjust the clearance (harder). Some have the shim on top of the 'bucket that covers the valve spring. With these, you will need a small, rather inexpensive tool specifically made for your model engine to compress the spring, allowing you to remove the shim. Other engines have the shim under the bucket, requiring you to remove the camshaft to change the shim. No special tools needed here, but reinstalling the camshafts correctly is absolutely vital. While this proceduere sounds rather intimidating, just remember that checking is all that may be necessary and no adjustments will need to be made. To check clearances, the idea is to turn the camshaft to that the cam lobe is pointing away from the valve and then measure the clearance with a feeler gauge and see how that compares to the recommended clearances. On shim type, clearances nearly always tighten and if the clearance is too little, you will need to install a thinner shim. I write down the clearance for each valve each time I check the clearances. If one valve tightens up faster than the others, this will give you a heads up to a possible future problem. Or, you may find they are ok this time but at the next check, you find some that need adjustment and will decide to take it to the shop that time. After a few checks and recording the clearances, you'll get a pretty good feel for how often you need to check them again. If you decide to do it yourself, by all means, get a shop manual.
take off the valve cover....you might also want to remove the glow plugs if you have trouble turning the engine over by hand. now make sure that the valve you are checking is completely closed by turning the engine by hand till you see the rocker arm to its highest level.....then slide your feeler gage between the rocker arm and the valve stem.....adjust if necessary.
Estoy muy apasionada de este mundo y todos mis amigos han confiado en mí a la hora de comprar un ordenador, yo siempre les he comprado de sitios web porque tienen la mejor oferta al mejor precio, pero, el ultimo ordenador que he comprado ha sido uno de juguete para mi hija, y como siempre he acertado, tiene la dimensión perfecta para ella, buenas canciones, aprende con él y imita muy bien un ordenador portátil con su ratón con todo, a ella le ha encantado muchísimo.
