First backlap on the Sun Joe 24V-CRLM15
Вставка
- Опубліковано 27 кві 2021
- After going through the process to scalp my bermuda lawn the mower needed tighter clearance to cut paper. It was time to do a backlapping to bring back the sharpness and minimize metal to metal contact between the reel and the bedknife. This process uses tools that most would have at home or could easily acquire at harbor freight. The lapping compound can be found at Autozone or Advanced Auto or ordered online at Amazon.
Just search "PerMatex Valve Grinding Compound" for an abundance of choices.
Good luck! Hope this helps

Awesome! Thx Jason. I definitely needed this. No one on UA-cam or Sunjoe themselves as a good tutorial like this
Very happy you found it useful 👍
I'm really loving this mower this spring. Started reel mowing in the fall with a manual reel, and bought this over the winter. It's perfect for 1k sqft at half inch. Thanks for this video, looking forward to my first backlap.
That's awesome! Really glad you found it useful 👍
Great video, thx for doing this!!
Hi Diving Adventures! Thanks for the kind words. Yes there are two allen bolts at each end of the bedknife fkr adjustment. Adjustment is required after backlapping. Please reach out if you have any additional questions 👍👍
Thanks for making this video. I was wondering if you can back lap this thing. I unfortunately hit a small twig and it damaged the bed knife. Seems to be ok for now. Started with 80 grit and down to 120. Only issue I had was that the 3/8 socket was really hard on the little piece of metal that fit inside that catches the gear wheel (not sure what to call it). Maybe net time go through the other side.
Hi John you are most welcome! Yes I have been also experiencing similar circumstances. I haven't filmed it because I scramble to get back up and running because here the grass is starting to grow fast and I'm cutting every other day.
The motor is.pretty powerful and unfortunately as we have found if you hit debris it can mess up the reel and bedknife. Filling as well as straightening the reel with vice grips or channel locks could be needed. I always check the lawn around the fence and beds before mowing now. It's very important to keep the yard clean when reel mowing.
I very much agree that opening up the drive side and removing the drive belt makes backlapping much easier so definitely so that next time 👍👍👍
jealous of your sunjoe with the front roller mod. Ever have an issue where one of the blades just jams on the bedknife? It was only one of the blades. At first I saw a burr, tried filing it, but never got it working right again. Maybe it hit something and bent the blade. I was inside the return window so just returned it. Missing it a bunch already
Hello Chris! Thanks for the interest. Yes I had the same issue and did a video on that issue. What happens is one of the blades gets bent. It is possible to straighten it out with some simple tools and patience.
Hope this helps!
Jason
Thanks. Do you have a video to straighten and sharpen bed knife?
Unfortunately I have not had to address that issue. I have filed out nicks in the bed knife with a file. Hope you were able to address your issues!
This mower is sold out absolutely everywhere. I hope it’s just a supply issue and not the ‘big boys’ being pissed a company came out with a very good power reel mower for under $300.
I plan on getting one of these when I can find one, haha.
Great videos.
Hi Brandon! I know!! I have an email notification set because I'd like to purchase a second one. Someone in the comments of one of my videos said SJ told them they will be back in a week. Keep looking!!
@@jasonochoada3083 I had the notification from sun joe that they re stocked yesterday.
@@8_one_8 Thanks 👍. I missed it in my inbox. Thanks for the heads up!!!
My 11/16 deep socket doesnt work. And its brand new! And you have a belt on yours, not mine. Hmm did sunjoe forget?
Maybe there is a small detail that I forgot to convey? There is a metal piece which slides through the shaft and that is what the socket grips. Maybe the design was changed so a different socket size is required. Regarding the belt it's actually better if the belt is removed because then your drill does not need to drive the motor which is hard on the belt / motor / and drill. If you didn't have a belt inside or it broke then the mower won't work, the motor can't turn the blades. If it worked fine then there is a chance you are trying to work on the non drive side.
Hope this works!
Did mine on the drive motor side, hope you didn't do any damage to the motor by doing it on the side you did.
Nope just more strain on the drill. Glad you picked the correct side 👍
The connection to the motor is within the hubs, doing it on the drive side doesn’t disengage it from the motor. I turned it on to confirm and it was still connected
Hi Bryant, you are correct. It requires removal of the 4 screws and removal of the plastic cover. Then you can remove the drive belt to disconnect the motor. Check out my roller modification video as I remove the cover in that video 👍
I would say be very careful with the pawl... I did this, and the pawl broke because that is all you are grabbing onto with the socket. Also, dot lose the pawl because your mower will not function without it.
Agreed always be careful but since the parts are light not much torque is needed. Always good to disconnect the belt 👍
Did you adjust the bed knife before sharpening? Before sharpening does the bed knife need to touch the blade so that the compound can be more effective in sharpening?
Hi Alex, I backlapped quite often so I would leave the bed knife in place. Then after backlapping I would adjust the bedknife until it cut paper. The grit in the sharpening compound will fill any gaps so I don't think you want the bedknife too tight. Hope this helps!
great video! after i sharpened the blades, i took it to mow and after about 15 min of mowing my blades would not spin. motor is running , nothing impeding the movement of the blades. Just that the motor would not make the blades rotate. any suggestions?
Hello! Sorry to hear you are having an issue. My guess is that if the motor is spinning but no blade movement perhaps the belt slipped off the geared pulleys. Have you been able to resolve the issue?
@@jasonochoada3083 not yet. where is the belt for the geared pulleys?
Hi Rick it's behind the right side wheel of looking at the front of the mower. Look around 7 and a half mins of this video ua-cam.com/video/xffMeCvljU4/v-deo.html
can the abrasive be applied to the blades and just power it up as usual to sharpen?
Hello! Thanks for the interest and comment. Unfortunately, to sharpen the reel needs to run in the opposite direction from regular operation. If it's run with abrasive as normal it would dull the reel instead of sharpening it.👍
My belt snapped, HOW DO I GET THE REPLACEMENT BELT ON? Someone please help. I have everything disassembled but it’s like the belt needs to stretch another 1/8 inch to slip over the gears
Hope you were able to get the belt on. When I reinstalled the belt I just got the edge started and then walked it on. Hopefully they didn't send you the incorrect part!
That belt is very easy to take off but hard to put back on. Any tips?
Hi Marcus, I totally agree. What I do is place it completely on the top small gear/pulley then start around the right side of the lower pulley/gear and start rotating the bottom clockwise and to l it starts to go on. Then I push it flush with a screwdriver carefully. Hope this helps 👍
I'm considering purchasing this mower. Would you still recommend it.
Hi Matt,. Thanks for the question. In short yes, I still like this mower a lot. I still think it's a good value as it's really the only mower of this type meaning not fully manual. I will be using it again this season again just be aware that it's fragile in regards to sticks and debris in the yard. I may purchase a backup this season in case I bend the reel. Then I don't have to be in a rush to get it back up and running.
Hey man, I had a business sharpen my blades and now my wheels won't roll forward. They only roll when I pull my mower backwards. Do you know how I can fix that?
Hi Catching up with Chubs! Couple of thoughts. Are you able to rotate the reel by hand forward or backwards? Maybe the bedknife is too tight against the reel or maybe they reassembled the drive gearing incorrectly when they put it back together.
@@jasonochoada3083 So I think the problem was the bedknife was too tight... I watched your video and I loosened it ever so slightly and it appears to be rolling better. I have another question if you don't mind. I've had my sun Joe reel mower since May and it's been great. I've been cutting it at 1 inch and it has looked good. We got a lot of rain about a month ago and II wasn't able to cut my grass for about a week. The grass got well above an inch and I decided I wanted to do a summer scalp to reset the height of cut. Well, lets say that was not my brightest idea. My grass is so thick that the sun Joe really struggled to cut the grass down to .6 (the lowest setting). It took me a couple of days, but I finally got down to the last bit of grass to scalp and catastophry.. all of a sudden, the blade stopped engaging. The motor was still running, bu the blade was cutting in and out. I took the wheel off and to my surprise, the belt was hanging on by a thread. Half of the grooves were gone. One side had groves, the other side was smooth and it had turned it into dust and was in a pile under the wheel. I'm new to reel mowing and I'm not a mechanic. I'm guessing that's why the reel kept dis-engaging? Once I'm able to replace the belt, will that fix the problem?
Hello! Glad backing off the bedknife worked and the video was a bit of help. Regarding second question yes it appears that the belt has stripped. The good news is SunJoe has a great customer service group the bad news is your mower will be down for a while. A suggestion for next time and what I do is to take my regular rotary mower and Cut it in stages down to as low as it will go. Then use the SunJoe to bring it down to the final level and a nice clean cut 👍
@@jasonochoada3083 I found a belt online that is the right size and ordered it! Once I get the new one put on, should that do the trick? Haven't had a chance to call Sun Joe, but I will. And thanks for the tip!
How RPM does this mower have?
Hello! Thanks for the great question. Unfortunately, I don't know the answer to that one. Sunjoe's customer service is pretty good so I bet they might be able to answer that one.👍
Did these real mowers stop production because I can’t find them
Hi Rob, from the look of this link they are currently out of stock. I've seen this happen quite often. I found the email notification does work or has in the past anyway.
snowjoe.com/products/sun-joe-24v-crlm15-ct-24-volt-ion-cordless-push-reel-mower-tool-only-rear-collection-bag
@@jasonochoada3083 Thanks I don’t want a manual real mower I don’t wanna spend a fortune on a expensive one there’s three that I am looking at the sun Joe, wild edge which has the same colors like a knock off and the cordless Scott’s real mower trying to get reviews to get the best one
And there’s another one by Earthwise so there’s actually four battery real motors that are from the $200-$300 range I wish there was a better quality one for around 800 but I haven’t found one yet anything that’s quality is in the thousands I don’t wanna spend that right now they had a manual one by Hudson which has a cam on it so you don’t have to walk That fast it spins very fast but no electric no motor and it’s 21:00
Yup, the link I attached is the Sunjoe 24v cordless. I looked at your three options and I'm willing to bet they are all coming out of the same factory. Can't speak for the other two but I had a good experience with Sunjoe when my unit was defective. No questions exchange or refund. They paid shipping both ways and I didn't have to return the defective one until I got the replacement. The downside is they can barely keep them in stock. Hope you are able to find the best mower for you 👍
Agreed. These mowers work well but the blades are prone to be damaged if debris is in the yard such as mulch/sticks etc...
I burned up my cordless drill doing this. But it was 20 years old so.....
Hi Curtis, I'm sorry to hear that... Did this still happen after disconnecting the drive belt under the cover?
No it was on the old manual reel mower that I had. It was about two years ago.
@@jasonochoada3083 I also like using the valve Grinding compound. It’s readily available at all the auto parts stores. I used to dab just a little bit of motor oil on the blades before and after I cut. But that old manual push reel mower was not working well once the fertilizer kicked in.
