Lawnmowers are great especially after what may have felt like a long winter - the grass will become very long and cutting long grass could put pressure on the motor resulting in a snapped belt...or it may have simply perished over the cold and dreary months.
The Qualcast Classic Petrol 35s lawnmower is a fantastic machine, it’ll help keep your lawn looking lush through those longer days leaving you to enjoy your trimmed lawn with your favourite iced beverage. However from time to time disaster can strike leaving your lawnmower no more useful as a chocolate teapot...no good.
If you have diagnosed that the fault lies with one or either of the two belts don’t worry because here at eSpares we can not only supply you with the correct belts but in this guide we talk you through just how simple the replacement process is.
This video shows an example on how to remove or replace the part on a typical machine, some models may be different but the procedure should be similar.
What You Will Need:
Step 1 - Safety Advice
Always make sure your lawnmower is switched off before you do any work. Just to be on the safe side either make sure the throttle is in the stop position or disengage the spark plug.
Step 2 - Opening Up
To begin this procedure you will first need to remove the grassbox and grassbox support this will give you more space and room to now remove the side cover. Held in place by four hex screws this will need to be removed to access the pulleys and belts.
Step 3 - Front Belt
With the cover removed you will now see the pulleys and the two belts - we can identify these as the front belt and rear belt (also known as the V-belt). The front belt runs between the motor and cutting cassette and the rear belt is toothed and sits between the motor and rear roller.
To get to the front belt you first will need to remove the lower pulley cover, this is held in place with a bolt and will require the use of a socket to remove it. Once the cover has been removed you can then simply slide the belt off.
Step 4 - Rear Belt
To access the rear belt is a little bit more tricky - you first need to remove the front pulley, this will just pull off and then you will also need to remove the top pulley. Connected to the motor spindle, you can use a wrench or large socket to remove this.
Holding it firmly you can begin to undo the pulley, once off you can then remove the toothed belt.
To fit the new toothed belt may be a tad bit tricky however the easiest process we found was putting the belt on at the bottom and then begin to rotate the pulley, this will feed the belt until it slips into place where you can then fit it over the top pulley.
There is a plastic nub, now you’ll want to make sure that the new toothed belt is on the outside of this nub. Once you're happy with the rear belt being fitted you can then replace the top pulley cover.
Step 5 - Front Belt Continued
With the rear pulley on we can now look at installing the new front belt - you can start by fitting the lower pulley back on this simply slid off originally therefore it should slide straight back on.
With it in place and before you secure the holding bolt you can now pop the new belt on - this should fit quite easy and once you're happy that it’s in place you can give it a turn or two to make sure it runs smoothly. Put the pulley cover back on and then using the socket secure it in place with the bolt.
Step 6 – Reassembly
All that is left now is to refit the cover, with the cover back in place you can then attach the grass box and the support and voila you’re done.
Understanding how to make such vital repairs will help ensure that your lawnmower can continue to perform its job. Some people may decide to either replace a perfectly good conditioned lawnmower or pay an expensive call out cost for an engineer to fix it when the process is very simple.
After completing this repair you can look back knowing that you have restored the life of your mower all while saving money.
