There are bleed screws on top of the filter housing and a primer lever on the fuel pump. The manual mentions when done leave the primer lever at the lowest point of its stroke.

All the bolts on the left side have been loosened. I noticed one is larger so they probably had one break/strip and had to drill/tap over-size. The bushings appear hardened but I was going to see if a carbide tool in a lathe could trim them down. My thought is they would be more uniform than grindin...

Replaced bushings on control shafts and got the left side steering band reclined and in. Replaced the bolt in question on steering clutch release w/ factory bolt. Then, loo...

Just what I was looking for. Thanks for the thread!
I'm too chicken to weld it solid so I will probably do like you- shave down the bushings and bolt solid.

Noticed the bolts and bushings that fasten the front equalizer to track rail on this machine had worn- shoulders of bushings rounded over. Bought replacements and it appears the head of the bushing doesn't bolt tight to rail- as though meant to have a little float. Is this correct or is something el...

Electrical problems are a pain! I usually start replacing the cheap. simple things first. Perhaps check connectors- loose, almost broken connector? My 450B had stiff steering lever and I think it's the shaft/bushings- one bushing worn all the way through. In the process of replacing those. If yours ...

Check the fuel tank vent, too. I had a similar event- tried to start up after running fine the previous day- nothing. Would chuff a bit with starting fluid. When I took the fuel cap off I heard a vacuum! Cleaned the vent on the underside of the tank (flet like ice/dirt in there), bled filters and it...

The clutch pressure plate may be okay... I fo...

Yeah, I had seen that post, too, and made sure the box was unchecked. I had't been using the BBCode on the photo site- once I used that for the link-BOOM!- pics posted. Thanks again. I spent today lining up parts. Found a replacement clutch operating shaft locally. Found the brake lining, while havi...

Flickr gives sharing options. The ones I tried didn't work. Trying again. http://flic.kr/p/jJNQG5 short url http://flic.kr/p/jJNQG5 http://www.flickr.com/photos/43541416@N02/12298853604/ full url https://farm3.staticflickr.com/2839/12298853604_a3f52f1c77.jpg IMG_3168 by labparamour , on Flickr BBCod...

Applied some heat to the fork and freed it up and moved it out of the way. Got the clutch out. https://farm6.staticflickr.com/5484/12315377844_29e738fa29.jpg 450B clutch by labparamour , on Flickr The fibers show a little wear but measure 0.18-0.19" thick. The steel have some pitting and will be rep...

Thanks for the link. This forum is great- I get help wrenching and help with my computer skills.
I will attempt to post some of today's pics.
(I did clean up the links to my original post...just need to figure out the [img] thing)

Oops! Hope my wife doesn't see this!
I realized I put link to pics from when I was logged in to Flickr "https" vs "http."
I will go back tonight and change links...and try to learn proper way to post img

The manual for my 450B shows for tranny temp sending unit: 200 deg @ 122 +/- 10% ohms.

First: Many thanks to Lavoy for the website and all those who post their work. Thanks, too, to Crawler123's tutorial on rebuilding the clutches on his 450. It's enough to be up to your elbows in grease but to take the time to document your work- much appreciated! https://farm3.staticflickr.com/2839/...
