Re: Logging Arch for my 40c?

My wheel arch uses a track roller, inner edges cut away to make it a smoother shape, on bottom in the throat and steel rollers (heavy pipe with bearings on a shaft) on the sides.

Re: Removing Final Drive Pinion Shaft

Did you remove the set screw from the steering clutch brake drum that secures the drum on the shaft?

Re: Rossa Master leak

The parts book will show you all the seals. There is also a JD manual SM2045 and Roosa Master/Stanadyne manuals available if you want to do it yourself. My personal choice (I know others will say different, that is their call and I respect that), I would remove the pump and have it gone through and ...

Re: 450C, No drive on right side, no fluid pressure

I always ask, just to confirm, does your serial number begin 450 C, a letter, then the 6 digit number? 450s have been often mislabeled, as far as the series, over the years and it makes a difference in information that applies. Also loader or dozer? There is just one pump supplying oil for the steer...

Re: Logging Arch for my 40c?

I recommend a wheeled one. Not bad once you get used to it and you can get the butts up better than one on the crawler. Just use a bit of care, if you get off to the side on a pull, many have flipped them. Ideally the hitch on the arch will swivel so as not to twist the crawler drawbar. They appear ...

Re: JD 350 track loader

Hi Jeff, The 450 breakdown Bruce pointed you to is close to the one for a 350. Here is the 350 breakdown from the parts catalog introduction. SN = serial number T = Tractor (You should have found a T in front of the 4) 4 = JD350 E = Crawler loader 3 = Diesel D = Transmission (Sliding gear with rever...

Re: 450C dozer hydraulic leak

I will admit to no hands on of that line. I have been involved in some in similar locations on other equipment and don't ever remember having to pull an engine to get a line. Sheet metal, supports, mounts, other lines, and accessories removed, yes. I won't say it wouldn't be easier if the engine was...

Re: JD 350B Steering Issue

Lavoy repairs and sells parts for JD crawlers. His store provides this site for us to use, so it is good to support him when we can. Send him an email (postmaster@jdcrawlers.com) or give him a call (phone number is on the home page) during Central time zone business hours. He will tell you if that i...

Re: JD 350B Steering Issue

Here is a link to the 350B crawler (only) parts catalog. The JD parts book is free to use. Lavoy can get you a copy through his store if you want a hard copy. If you look at the steering section, brake linkage assembly page, I think you are talking about item # 10, lever T23624. Arm, item 13, has th...

Re: JD 350 track loader

Welcome to the board. For future reference your 350 posts should be on the Late Models Board. Lavoy will likely move this post over there when he sees it. If it is a 1974 as you think it will be a 350B, not a straight 350. The serial number tag locations are as follows. 350s and 350Bs up to serial n...

Re: Looking for a backhoe attachment my 450

How steady of work do you have for a backhoe? You might be money ahead to plan your work and rent a mini hoe for a week end or two. Using a rental will keep your loader ready to move material out of the way without folding everything up to move a bucket or two of material. That also will prevent put...

Re: 450B fluid types

The list is most likely ok but you should get a manuals (at least Operator's and Service/technical) for your machine to confirm. Lavoy sell manuals in his store and can help you get the right ones.

Re: Straight 450 steering issue

Just for the record. I have to believe R/O oil is not the right oil for any wet clutches. It appears to just be a hydraulic oil with rust and oxidization inhibitors from what I see of several brands. R/O might get by in your 450 hydraulics but it should not be anywhere else in your machine unless it...

Re: 350B NO GO

Before you start checking things I suggest you contact Lavoy and get a set of manuals for it, if you don't have them. Read and study them, do the suggested tests; then check what is indicated. When you changed the filters did you remove and clean the element inside the transmission case? What did yo...
