42cc craftsman chainsaw crankshaft bearing/oilseal replace

Oil leakage from crankcase kills idle speed. Engine runs at high speed. Need to replace bearing/seal both sides. I have the parts.

What's involved for a user (non-mechanic) to install parts?

Hi kent

you need to replace the clutsch,handle ,air filter,carburator,fan housing and flyweel.Take off the cilinder and separate the two pieces of crankcase.Change the bearings and seals with the new ones.(to replace the clutsch and flyweel you need to block the piston in the cilinder.

WE INSTALL NEW RINGS AND BEARINGS FOR MAZDA 323 AND WHEN WE START IT THE IDLING IS TO HIGH AND THE OIL LITE FLUSH


sound like intake leak and oil pressure problems.check oil pressure did you replace crankshaft or had it reground if you replace engine bearings and the bearings have too much clearance between bearings and crankshaft you will lose oil pressure also oil pump need replacing if you doing over haul.

Oil gauge drops low at idle


Low oil pressure at idle can be caused by an engine with worn rod or main bearings due to (usually) high mileage . This however does not mean the engine is still not serviceable as long as the oil pressure is low only at idle. The pressure should at minimum get into the normal range at anything above idle speed.Not much oil pressure is really necessary at LOW speed. At low speed, as long as there is oil getting to the bearings, even at low pressure, you are OK. In a high mileage engine the oil pressure is often low at idle simply because the oil pump is turning slowly and cannot maintain higher pressure between the larger than normal crankshaft and bearing clearances. As speed increases the pump turns faster and supplies more oil and the pressure should go higher. Low pressure as long as it is only at idle is not a problem. However at higher speeds the pressure should be in the normal range. Such a worn engine can benefit from higher viscosity (thicker) oil such as 20W-50 in above freezing weather and 10W-40 in winter. That will increase idle pressure and the thicker oil film maintains a better film between the worn parts

Chainsaw starts normally idles well increase speed and cut a log then decrease speed and the motor stops


Have you tried changing the gas you are using? Sometimes with the addition of ethanol, water condensation is attracted and builds up in the system, creating a fuel mix that affects performance. Also, make sure your settings for High speed throttle are correct. You may need to make a small adjustment on the screw marked H for running high throttle.

What are the symptoms of a bad coil on my Poulan chainsaw? Mine only sparks at high RPM's, as tested with my electic drill motor spinning the engine and grounding the removed spark plug to the engine...


There has to be a reasonable spark at hand cranking speed, with most electronic ignitions they work off speed of rotation so you do need to crank the engine at a fair speed, check the air gap between the flywheel magnet and the ignition core, this should be around 0.3mm, if there is not spark at all when cranked well it will be a replacement unit required.

The saw stalls when under load and at high speed, runs good at idle and mid speeds, when you pull throttle all the way back with out load saw will bog down and die.


Check the fuel filter, air cleaner, and muffler for plugging. Check the fuel lines for decay or other damage. Make sure the carburetor is solidly mounted to the engine. Hope this helps!

Saw will lnot start----needs gas intake adjustment


Turn both jet screws CW to stops (lightly), then back out each CCW 1-1/2 turns. This is a basic setting that will allow the engine to start and run. Let the engine warm up, then pull the throttle full on--turn H screw CW until the engine speeds up somewhat. Proper adjustment is when the engine is 4-stroking unloaded, but immediately 2-strokes when cutting. Release the throttle and adjust L CW until the engine idles fairly well, but allows the engine to 'follow the throttle'. Adjust idle speed screw so that the chain stops turning, but the engine continues to run. Hope this helps!

Saw will start and run about 20sec. till you push the choke in and then stop like it run out of gas ,replaced the fuel line and filter , put a kit in carb. adjusting the h & l screws makes no...


Go to: http://www.drystacked.com for a 12 page PDF document on Walbro carburetors. Pay special attention to the caution about the lower chamber gasket and the diaphragm. Crankshaft seals rarely become a problem until the crankshaft main bearings have worn so much that the crank shaft can be visibly moved sideways. Make sure the muffler and air cleaner are not plugged. A basic setting for H and L jet screws is turn both CW to stops (lightly), then back out CCW 1-1/2 turns each. The engine should start and run with these settings. Allow the engine to warm up, then open the throttle and adjust H CW until the engine starts to speed up but continue 4-stroking. Proper final adjustment is 4-stroking, but immediately 2-strokes when cutting. Let idle and adjust L CW until engine runs fairly well, but will allow the engine to 'follow the throttle'. Set idle speed screw so that the chain stops turning, but the engine continues to run. Hope this helps.
