How to Adjust the Guide Bar & Chain Tension on the Husqvarna 55 Rancher

Hemera Technologies/Photos.com/Getty Images

Maintaining proper guide bar and chain tension is essential to the safe and efficient operation of any chainsaw. On the Husqvarna 55 Rancher, adjusting the bar and chain is designed to be accomplished in the field with basic tools and a minimal amount of time. Chain tension should be checked before starting the chainsaw every time you use it. Failure to maintain proper chain tension could result in damage to the saw or injury to the saw operator.

Check the chain tension. Release the chain brake by pulling the front hand guard back toward the front handle. With your left hand on the top of the front handle, use your right hand to grab the chain on the top of the bar. Attempt to rotate the chain. It should spin freely and no slack should be seen in the chain on the underside of the bar.

  • It should spin freely and no slack should be seen in the chain on the underside of the bar.

Loosen the two bar nuts one full turn, using the wrench end of the combo wrench or 1/2-inch socket.

Use the screwdriver end of the combo wrench or the flathead screwdriver to turn the chain tensioner screw on the front of the saw -- clockwise to increase the tension, counterclockwise to reduce the tension. When properly tensioned, the chain should rest snugly against the underside of the bar with no visible slack.

Hold the bar tip up with your right hand and use the wrench end of the combo wrench or 1/2-inch socket to tighten the two bar nuts.

Chain Tension On A Husqvarna 445

When a chainsaw's chain is under too much tension, it's subject to excess friction when it rotates, which makes the chain more likely than normal to break. The chain is under the right amount of tension when its tie straps touch the guide rails on the bottom of the guide bar and the chain doesn't sag away from the bar. The chain should be loose enough, though, to turn easily by hand. Rotating the screw clockwise increases the tension. Chain tension needs to be checked regularly as you use the saw. Put on gloves, grasp the chain between your fingers, lift the chain away from the guide bar and release the chain. A new chainsaw chain stretches during its initial use. Before you make any cuts with a new chain, let the saw run at one-half throttle for a few minutes, and then stop the saw's engine and check the tension after the chain has cooled.

  • The chain is under the right amount of tension when its tie straps touch the guide rails on the bottom of the guide bar and the chain doesn't sag away from the bar.

When using a new chain, check the tension frequently until the chain is run-in.

Never adjust the bar and chain while the saw is running. Make sure the stop switch is in the "off" position. Always wear gloves when working with the chain in order to protect your hands.

55 Rancher Chain Tensioner

Hi Folks,

You guys helped me fix my 55 Rancher in the past, so now that I need help here I am again. Here are the specifics:

Model: Husqvarna 55 Rancher
Code on tag top line: 967 05 29.00
Code on tag bottom line: 02 2301618

The saw still runs great. The issue this time is that the bar chain tensioner screw fell out while cutting up a tree for firewood. With a magnet I was able to find the adjuster screw in a pile of chips, and the pawl was still in the saw. The plastic "nut" was missing, so I purchased a new nut (part number 501452702), and theoretically it should go right back together.

The problem is that I can't remember how it goes together. I've scoured the internet looking for pictures or videos showing the tensioner, but have found nothing, and the exploded parts diagrams aren't as useful as I would like.

Anyone got a closeup picture?

Barring that, maybe someone could answer a question about the plastic nut. The nut I got is unthreaded, so seems like it should just slide over the tip of the screw. Am I supposed the thread it onto the screw until it reaches the unthreaded shoulder of the screw?

Thanks in advance for any help you folks can give me.

the first symptom of a cold is usually a sore throat. this is generally followed by sneezing or a blocked, sore or runny nose. usually, 1 in 3 people with a cold will get a cough and feel unwell.

colds are caused by viruses. antibiotics cannot treat viruses. instead, drink plenty of liquids to replace those lost from sweating and runny noses. get lots of rest and eat healthily. do not ask your gp for antibiotics for a cold.

you will usually feel worse during the first 2 to 3 days before gradually starting to improve. your symptoms will usually last about a week.

cold and flu symptoms are similar but flu tends to be more severe.

cold

  • appears gradually
  • affects mainly your nose and throat
  • makes you feel unwell but you're ok to carry on as normal - for example, go to work

  • appears quickly within a few hours
  • affects more than just your nose and throat
  • makes you feel exhausted and too unwell to carry on as normal

cold symptoms can include:

  • blocked or runny nose
  • sore throat
  • headaches
  • muscle aches
  • coughs
  • sneezing
  • a raised temperature
  • pressure in your ears and face
  • loss of taste and smell

the symptoms are the same in adults and children. sometimes, symptoms last longer in children.

causes of colds

colds are caused by viruses. they can easily spread to other people. you're infectious until all your symptoms have gone. this usually takes about a week.

colds are spread by germs from coughs and sneezes which can live on hands and surfaces for 24 hours.

to reduce the risk of spreading a cold you should:

  • wash your hands often with warm water and soap
  • cough into your elbow to stop germs getting on to your hands and spreading to other people
  • use tissues to trap germs when you cough or sneeze
  • bin used tissues as quickly as possible

how to prevent catching a cold

the best ways to avoid catching a cold are:

  • washing your hands with warm water and soap, especially before eating
  • not sharing towels or household items, like cups, with someone who has a cold
  • not touching your eyes or nose. you can infect your body if you've come into contact with the virus.
  • staying fit and healthy

Always file cutting teeth from the inside face. Reduce the

pressure on the return stroke. File all the teeth on one side

first, then turn the chain saw over and file the teeth on the

other side.

File all the teeth to the same length. When the length of

the cutting teeth is reduced to 4 mm (0.16") the chain is

worn out and should be replaced.

General advice on setting raker clearance

When you sharpen the cutting teeth you reduce the raker

clearance (=cutting depth). To maintain optimal cutting

performance you must file back the raker lip to the

recommended height.

See the Technical data section to find the raker clearance

for your particular chain.

On a low-kickback cutting link the front edge of the raker

lip is rounded. It is very important that you maintain this

radius or bevel when you adjust the raker clearance.

We recommend that you use our raker gauge to achieve

the correct clearance and bevel on the raker lip.

WARNING! The risk of kickback is increased

!

if the raker clearance is too large!

Setting the raker clearance

Before setting the raker clearance the cutting teeth should

be newly sharpened. We recommend that you adjust the

raker clearance every third time you sharpen the chain.

NOTE! This recommendation assumes that the length of

the cutting teeth is not reduced excessively.

12 –

English

SAFETY INSTRUCTIONS

To adjust the raker clearance you will need a flat file and a

raker gauge.

Place the gauge over the raker lip.

Place the file over the part of the lip that protrudes through

the gauge and file off the excess. The clearance is correct

when you no longer feel any resistance as you draw the

file over the gauge.

Tensioning the chain

WARNING! A slack chain may jump off and

!

cause serious or even fatal injury.

The more you use a chain the longer it becomes. It is

therefore important to adjust the chain regularly to take up the

slack.

Check the chain tension every time you refuel. NOTE! A new

chain has a running-in period during which you should check

the tension more frequently.

The position of the chain tensioning screw on our chain saws

varies from model to model. See the What is what? section to

find out where it is on your model.

Tension the chain as tightly as possible, but not so tight that

you cannot pull it round freely by hand.

Undo the bar nuts that hold the clutch cover/chain brake.

Use the combination spanner. Then tighten the bar nuts

by hand as tight as you can.

How to: Husqvarna 55 Chainsaw Maintenance

By Chris Deziel

Proper chainsaw maintenance ensures a happy ending.

Hollywood horror movies have relegated chainsaws to a place of infamy in popular consciousness as implements of wanton destruction. The reputation isn't entirely unwarranted because chainsaws are powerful tools, but they are also immensely useful in the right hands. If you own one, such as the Husqvarna 55 Rancher -- which is a medium-duty saw suitable for clearing brush and cutting lumber, then perform certain maintenance tasks regularly to keep it in good working order. Using a chainsaw without giving it the tender loving care it needs can turn any job with it into a nightmare.

Tasks for Each Use of the Saw

Check the Husqvarna 55 Rancher's chain lubrication. Start the chainsaw's engine, and hold the saw over a flat surface, such as a tree stump, while you engage the throttle. The chain should produce a fine splash of oil. If you don't see that oil, clear the oil port. You can do that task when you service the guide bar.

Clean the brake handle, and check the operation of the automatic brake. Begin the process by turning off the chainsaw's engine and disengaging the brake. Hold the saw over a stump or log, and let the guide bar fall onto it. The brake should automatically engage when the bar hits the wood.

Pull the wire off the spark plug, and unscrew the chain sprocket cover with a socket wrench. Check the brake band, which is attached to the chain sprocket, for wear. It should not be thinner than 0.6 millimeters.

Remove the guide bar and chain, and clean both with a rag. Clean out the oil port, if necessary, with a piece of 16-gauge wire. Turn the bar over, and reinstall the bar and chain. Inverting the bar ensures that it will wear evenly.

Tighten the chain tension by turning the tensioning screw clockwise with a flat-head screwdriver. The screw is on the front of the engine housing, next to the bar. The chain shouldn't sag, and you shouldn't be able to lift it high enough to disengage it from the bar, but it should turn smoothly.

Sharpen the chain, using a cylindrical file to set the tooth angle and a rake gauge and flat file to set the cutting depth. Sharpen each alternate tooth with the cylindrical file. Turn the saw around, and sharpen the rest of the teeth. Place the rake gauge on top of each tooth, and file the tooth flush with the gauge, using the flat file.

Check the saw for loose screws, and tighten them.

Tasks for Periodic Maintenance

Remove the Husqvarna 55 Rancher's air filter weekly, and clean it with compressed air or wash it in soapy water, rinse it in clear water, wait for it to dry and put it back in the saw. Replace the air filter after about every 100 hours of the saw's use, or service. Unscrew the muffler cover with a screwdriver, remove the spark arrestor screen and clean it with a wire brush.

Unscrew the spark plug with a spark plug wrench after every 10 to 20 service hours, and check the gap between the plug's electrodes with a gapping gauge. Adjust the gap with pliers, if necessary. The correct gap width is 0.020 inches. Change the spark plug after 100 service hours.

Inspect the starter rope for wear frequently. Replace it when it's frayed and appears ready to break.

Clean the engine housing, including the cooling fins on the fan housing, the carburetor body and the air box, using a rag.

Lubricate the clutch bearing with penetrating oil weekly, or after 20 service hours. File burrs off the side of the bar, using a flat file, whenever you notice them.

Tips

  • Examine the spark plug for wear and carbon deposits, either of which signifies the need for carburetor adjustment.
  • Replace the chain if the length of the cutting teeth is fewer than 4 millimeters.

Warnings

  • Always adjust the tooth depth with a rake gauge and flat file after filing the cutting edges. Failure to do this increases the possibility of kickback.
