Re: Blower fan for a 450 straight

Maybe they are there to provide additional fan clearance for the crankshaft pulley. They are only about .080" thick so they can't be helping a whole lot. Oh, well still looking at other options. I would even consider an electric if there was a sturdy one available. Most seem wimpy even for automotiv...

Re: 450B power steering pump

If it is the same pump and assist actuators as a 450, it probably has air in it. I put new seals in the actuators and it took a long while to bleed the air. If you look in the reservoir, you will see fluid being pumped and air bubbling up when you pull the sticks. Now, no pulsing. I used hyguard, bu...

Re: Clutch and brake adjustments

As far as the manuals go, try to find the latest revision for the model 450(straight). The manual changed somewhat between the original Edition and the final Edition. I ended up with two editions. The first was an early revision that came with the machine and had some really useful notes by the orig...

Re: Blower fan for a 450 straight

I did not see that there was a substitution. I guess that OEM will be a fall back position if I can't find a good used one. I have a couple of other things I am looking at. $200 is pricey for a fan. By the way, do you know what the 24M7238 washers are for? I was thinking they were bushings but they ...

Blower fan for a 450 straight

Hi I am looking for a six blade blower fan for a 450 straight. Equivalent to an AT27701. Either new aftermarket, oem, or used in good condition. An aftermarket that can be adapted would be ok also. Has anyone tried an electric aftermarket on the front of the radiator? I thought I could find anything...

Re: Brake band dragging on a 450()

Closed it up with the brake band detent backed off another notch. The extra travel at sticks before the brake engages is more than I like. Aside from that the function is fine. I will run it for a while and then try to re-adjust it.

Re: Brake band dragging on a 450()

I am pretty darn sure none of the linkage is sticking and that the return springs are in place. I just rebuilt the clutch and brakes last fall. Only have about 30 hours on it since. Everything I could see looked right. I went through the whole process again this morning. Exactly like the manual says...

Brake band dragging on a 450()

I put new brakes and clutches on a 450 straight about a year ago. Brakes were set intentionally loose when reassembled. After about 20-30hrs the brakes got quite a bit looser so I went through the manual's process for adjusting. To the ABSOLUTE letter. The clutch was still dead-on but the brakes wer...

I tried to contact him by email a month ago with no response. With the whole Corona disruption he may just have pulled back for a while.

Re: Oil and HLR filters

I will use a JD filter next time. It has to.be the only item JD sells that could possibly described as inexpensive. If the quality is there I shouldn't complain. I will open it up and see what's inside after it gets some time.

Oil and HLR filters

I just changed engine oil and HLR filters on a 450(). Both had Wix 51243 filters. Being an aircraft mechanic I cut the filters and had a look at at the elements. The Hlr filter had some John Deere color paint chips on it. Does JD really paint the inside of the Hlr? I noticed some similar chips in th...

Re: Blade float on a 450() with a Drott 4 in 1

Figured it out. It just takes a lot of force to get into the float detent. More than I am normally comfortable putting on a control lever. It works well. Owned the dozer for a couple of years and never knew the function existed.

Blade float on a 450() with a Drott 4 in 1

This might be a really dumb question. Does the a 450 straight with a Drott 4 in 1 have a float position? I can't seem to get mine to get into that mode. Is there a trick with the controls? Is it just broken, modified or somehow badly adjusted? Does the 4 in 1 even have that feature? The ops manual i...

Re: Possible water pump issue, JD450

Another question: It looks like the parts for a rebuild will be available and by Deere standards relatively cheap. The question is rebuild it or buy the assembly. I have a bearing press and it looks straight forward to rebuild. I have asked Lavoy to price it both ways.

Any opinions?

Re: Possible water pump issue, JD450

It has been running cool. I will not be able to take a look at it until mid week. Getting the fan bolts off looks like the biggest challenge. I need to come up with a plan.
