I hope this video was helpful for you. Thank you for watching, and good luck with your repair!
Excellent video, very well done! Thank you.
Thank you, and thanks for watching! : )
That was One of the best how to videos I've seen ever. The camera work was awesome you showed every step. Well done I have a 345 and it's the same process for it. I will be doing mine in the future.% star
Wow, that's great! Yes, it's time to get these old snowblowers ready for the snow! : ) I have a few other videos on this 285 which will be similar/same for your 345 on a playlist. Thanks for watching!
Hi very well done. Those carriage bolt holes in the chute, normally the bolts have large knobs so you can adjust the angle by hand when using the machine.
Thank you - I didn't know that, but that makes sense! : )
In the process of rebuilding my snowblower a second time
in 20 some years.
Your video was very well done with lots of good detailed instructions. I learned a number of good points from your video.
My first rebuild required a new augger shaft to be made due to bend in old one. This overhall is a result of same problem from a pice of cement going through blower. Both times blower had a severe vibration due to a bent shaft. Measured latest shaft in v-bolocks and it has 0.083" runout In middle area. Lots of unbalance from the auger high-speed and large diameter.
Wanted to mention this problem incase someone else does not have structure cracking like yours had and there is too much vibrations.
Thank you very much for the time and good quality of your video.
Wow, thanks for adding those tips! And thanks for watching : )
Good work.
Thank you, and thanks for watching! : )
Thank you for making this video. Was very helpful for me.
Wow, that's great! I'll be getting ready to put this snowblower back on my our JD soon - we'll see what this winter looks like! Thanks for watching : )
Just the thing I was looking for. Thanks for this content!
Thanks, and thanks for watching! Yep - snow will be falling soon and we'll be back on the snowblowers! : )
Excellent! What a job, but it was well worth the time and effort! It looks great and performs great!
Thanks, and thanks for watching! : )
In the process of reinstalling engine someone else ripped out on a 245 with the kawi. As there’s not many videos on these mowers. Loved the video your very detailed and would be great if you made a video on how wiring is ran to the motor as-well as fuel lines.
This manual (pdf) from MyMowerParts.com might be very helpful for you - it covers several Kawasaki engines, including the FD590V:
www.mymowerparts.com/pdf/Kawasaki-Service-and-Repair-Manuals/FD440V-FD501V-FD590V-FD611V-KAWASAKI-SERVICE-REPAIR-MANUAL.pdf
I have a video about the fuel lines here:
ruclips.net/video/t8VZUWgboBo/видео.html
I hope that helps - good luck, and thanks for watching! : )
Ok, I have a 265 I picked up from an implement dealer in Hopkins mn for only $200. Missing the mower deck as they ONLY used it to blow snow, so it has this Snowthrower.
WOW, Your video is TOP Shelf. However, I'm questioning the counting of the chain at 21:45. It seems like the initial vertical link at 21:50, was not counted. Am I wrong? So I'm thinking it should be 37links PLUS the 1 master link?
Wow, that's a great deal!
As for the links: I'm counting the outer links (plates) only, and there's 36 outer links, plus the outer master link.
So, there's no "vertical link" to count at 21:50 - the link that's in the vertical orientation is underneath the ends of the two "horizontal" outer links. I have the chain folded such that the only outer "vertical link" is the master link at the left-hand end - all the other outer links are in the "horizontal" position.
I hope that helps : ) Thanks for watching!
@@L35inColorado Ok, I'm new to this machine. thanks !
Also, what really piqued my interest was the sound of your nice voice! (I'm a BIG Music guy with an ear for notes/key's/recognizing people by the sound of their voice) My Granddaughter from 0-5, lived with us while my daughter finished College. Anyway, LONG Story short, she took a Small Engines course this year in High School, and rebuilt her own B/S engine! There is hope for this next generation!
@@henryhill3778 That's a great story - thanks for sharing that! You all must have given her the confidence to try new things and to learn to work with her hands, and that is a SUPER gift to give to your grandaughter! : )
I have a JD snowblower. their idler with bearings only last one year at over $40.00 each, i need 2. i bought replacements at Tractor supply for $14.00 ea. drilled drain holes for snow and placed silicone on the bearings seal to keep out water and salt. the bearings lasted over 10 years. Today JD wants $50.00 per idler i bought them online for $20.00 ea. BTW i have a JD X320 made in china and is a pos. my previous JD 165 lasted over 20 years without any reapirs at all. made in U.S.A.
Ah man, I'm sorry you had all that trouble, but thanks for adding your tips! I am very disappointed to see JD selling "made in China" bearings at "made in Japan" prices. Whenever I can, I use the cross-reference documents online to find bearings from a non-China supplier, and now I have to consider that JD is made in China oftentimes. This old JD 285 is coming up on 35 years old - it still runs well and does what it's supposed to and is an old USA-made JD with a Japanese Kawasaki engine. I guess we just need to keep the old ones going! : )
Thanks for watching!
@@L35inColoradothank you for your supportive words. btw. JD sells a carb kit for my x320 at $150.00. I bought a new carb for 75.00. Also replaced main drive belt with aftermarket brand saving over 50% on price. Thks and keep the videos coming.
