Valve clearance adjusting tool

Ensure you take the gasket off the head, too. Place the cover away from the work area. To check valve clearances, the piston needs to be at top dead centre TDC. This is the point in the cycle where the cams are not applying any pressure on the valves; the resulting gap between the two is the valve clearance.

Check the sidebar over the page for an explanation of finding top dead centre. The term valve clearance describes the gap between the cam or rockers on a Honda and the valve bucket. Using a narrow pair of feeler gauges, determine the clearance using trial and error by seeing which gauges can slip under the cam freely. On all bikes except YZFs from onwards, exhaust valves are at the front and inlet valves at the rear.

If the clearances are within tolerance, bolt your bike back together and go riding. If not, continue following the series of steps below. Most bikes run automatic cam-chain tensioners. Simply remove the covering bolt, and then use a screwdriver to unscrew the tensioner until you feel a click and the chain becomes loose. To remove the camshafts, which is necessary to access the valves that are out of spec, the first step is to remove the journal holder.

Undo the bolts in the order recommended by your manufacturer to prevent the holder from warping. Two dowel pins keep the cam and journal holder aligned, so make sure you take care to grab them or they can easily fall down into the engine. Then lift the cam s out of the seats to access the buckets and shims. Wrap the cams in cotton while out of the bike.

Another option is to simply put a screwdriver under the chain as shown here. Using a pair of long-nosed pliers, carefully lift the buckets off the top of the valves. Use only enough force as required to keep a firm grip on the buckets to prevent damaging them. The shim will then either be sitting on the valve top or stuck up inside the bucket. Keep the buckets and shims together and write down which valve they came off.

Using a pair of vernier calipers, measure the shims for the valves that need adjustment. Manufacturers use shims in the manufacturing process to counter for tolerance variances in the buckets, cams, valves and head.

At this price this number is not quite enough. But - - I do not use it w In addition, since it can be used for adjustment of PlugGap and measurement of various parts of Engine at Overhaul Would it be better to have more sheets - - At the time of opening, the root fasteners were loose and it was nearly RoseRose.

There is no problem when tightening again. I bought it to make Valve clearance adjustment It's easy to use because it is set finely While paying attention not to rust, I would like to use it for the Large thing View detail.
