If the engine is still running at normal revs, and the chain slows down, then it’s a problem with the clutch. Chain and break are fine, and the saw starts up good still, no funny noises, the chainsaw begins to loose rev fast once i begin to cut. If the engine and chain both slow in the cut then I don’t think this is a clutch issue, a clutch issue would most likely allow the engine still rev but the chain would stop.
Typically, bad clutch springs let the clutch slip, meaning RPM rises but the bike will not accelerate, usually worse in the higher gears. Unlike a four wheeler or truck, the chainsaw operator doesn’t have to engage the clutch or put the chainsaw in gear. The type of clutch a chainsaw uses – which is the same kind you find on a string trimmer – is a centrifugal clutch.
If the chain continues to turn or if the chain slips under load you should stop using the equipment immediately and have it evaluated by a local authorized service center. If you are experiencing a problem with your product, find a solution by using our support assistant.
Most pro saw users in the Northwestern US will experience a problem or two with the clutches on their pro saws at some point during their saw’s life. These long cutting attachments require more clutch “Slip.” Over time this causes extra wear on the friction surfaces of the clutch shoes and drum. While the use of long bars and other operating conditions may accelerate clutch wear, clutches on today’s saws deliver good service life if they are maintained.
how to tell if chainsaw clutch is bad Related Question:
Can a chainsaw clutch slip?
The surfaces of the clutch shoes are coated with a high-friction lining, much like the brake shoes in an automobile, and this lining wears down slightly each time the clutch engages. Eventually, the lining becomes too thin to do its job, and the clutch begins to slip. This happens for two reasons.
How do I know if my clutch spring is bad?
Typically, bad clutch springs let the clutch slip (as does worn out fiber plates and overheated/burnt/blued steels), meaning RPM rises but the bike will not accelerate, usually worse in the higher gears.
Why does a chainsaw chain slip?
Chainsaw chains come off the bar due to worn-out bars, worn-out sprockets, and wrongly set tension. You should also note that with continued use, chains lose their tension and hence are more likely to come off the bar when you least expect it.
What is a chainsaw brake?
One of the most important chainsaw safety features is the chain brake, which stops movement of the chain in the event of kickback during operation. The chain brake is activated when the front hand guard, located near the saw’s upper handle, moves rapidly toward the chainsaw operator.
What does a clutch drum do?
An outer drum that turns freely – This drum includes a sprocket that engages the chain. When the drum turns, the chain turns. A center shaft attached directly to the engine’s crankshaft – If the engine is turning, so is the shaft.
Why is my chainsaw burning the wood?
Your chainsaw burns wood because of poor lubrication Lubrication allows the mechanical parts to coordinate much better by avoiding a phenomenon of friction which risks causing traces of burns. This is one of the main reasons that your appliance gives off too much heat and that the wood burns.
Why does my chainsaw chain dull so quickly?
Dirt Causes A Chainsaw To Dull If you’re cutting through logs and your angle of approach is too steep, a simple cut through could nick dirt or even worse, rocks on the floor causing your chainsaw to jerk, thus dulling.
Why is my chainsaw smoking when cutting?
This most commonly is a result of a dull chain and exerting to much pressure on the bar and chain trying to make the chain saw cut. This could also be either a lack of bar and chain oil ( tank empty, restricted oiler hole ) or an inferior type of oil that is being slung off the chain and not lubricating.
Why is my chainsaw chain not tightening?
If you’re having trouble tightening the chainsaw chain, it may be adjusted properly already. Check the tension on the chain by grasping it in the middle of the top of the guide bar and giving it a quick snap. The chain should quickly snap back into place with no sagging on the underside of the guide bar.
How long does a chainsaw bar last?
Re: how long does a bar last The next, a Granberg, lasted about 2 months. About that time Stihl started using them with the same results. A good bar can be filed a few times on both sides and the tip replaced when needed. They could last almost as long as the saw.
What happens when the clutch goes out?
A broken clutch takes away the connection between the engine and transmission, leaving your vehicle with the inability to move correctly. With a manual transmission, you can still drive your car. Driving with a broken clutch is NOT recommended.
How long should a clutch last?
As a rule of thumb, most clutches will last in the region of 60,000 miles before the need for replacing. However, we have had to replace some at around 30,000 (or less), and we’ve seen some clutches that have continued to keep going past 100,000 miles.
What would cause a clutch not to engage?
A clutch that won’t engage at all means there is serious damage somewhere. Check for a bent linkage, a seized slave cylinder, or a seized throw-out bearing. Beyond those, check for binding in the linkage, a corroded cable, or a failed friction plate.
How do I get the pressure back in my clutch?
Open the bleeder valve and allow the fluid to run out until it slows down, while your friend maintains pressure on the clutch pedal. When the fluid flow slows, while your friend still has pressure on the clutch pedal, close the bleeder valve. Let the clutch pedal back up and repeat the process.
How do I know if its the clutch or gearbox?
Turn the engine off and see if you can select a gear. If you can then it’s usually clutch trouble; if you can’t then the problem will lie with the gearbox or gear linkage.
