Re: 450 dozer transmission oil pump dowel pin T20902

A search using the part number on the JD parts site shows that is the only place that dowel pin was used. Finding a salvage yard with a transmission parted out is likely about your best chance. Send Lavoy an email or give him a call he might have a suggestion of someone to check with. What is your g...

Re: A new to me 450G or not?

Welcome to the Boards.

I hadn't seen that before. The TO should mean it was built in Dubuque. DX75M brings it up as a Hitachi model in a web search. Those apparently used the 4045 engines like the 450G. The actual 6 digit serial number may relate to the Hitachi run of units. Good luck.

Re: 350C steering issues.

First thing I am going to ask is, are you certain it is a C model, confirmed by the serial number? We need to be sure as the C had wet steering clutches and brakes, the straight 350s and the Bs had dry steering systems. Is this a dozer or loader? In first gear forward, if you push against something ...

Re: 350 blade arms packed solid with mud/debris

Welcome to the boards.

A combination of poking with steel rods, a lot of water from a hose, and using a pressure washer are about the best I can think of. Good luck.

Re: John Deere 450c dozer transmission issues

Welcome to the Boards. You may have some seals starting to fail. Cold oil can hide some leakage. As the oil and components warm leakage will increase. The other thing is a pump that is worn generally drops off as it warms. If you leave the gauge in place does the oil pressure change as it warms up?

Re: high/low to reverse shift

Welcome to the Boards. Yes, speed of shift can be adjusted. The 450E has a two-volume set of Technical Manuals. TM1330OP is the Operation and Test Manual used to check operating specifics, adjustments and diagnostics. It has the info on adjusting the speed of shift and other adjustments that may nee...

Re: Engine temperature gauge 450E

Welcome to theboards. Check the temperature at the left rear of the head where the temp sender for the engine is located and also check the temp of the head behind the outlet neck to the radiator when the gauge is showing hot. If those are less than 175 up to about 200 degrees you most likely have a...

Re: Hydralic Oil Filter Light

Sounds like cold oil is triggering the light. If it stops coming on after running a bit, that is likely the cause. Only running 15 minutes to half hour really is not getting it warmed up enough for it to clear condensation from oils and gearboxes. You might not have many hours on the filter but it m...

Re: John deere 350b only cuts one way

Did you check the condition of the splines in the hub the ring gear rides on and on the shafts, out and through, the final drive?

Does it have power assist steering and is all in related linkages moving properly?

How many steel discs and how many friction discs did you install?

Re: John deere 350b only cuts one way

What was the reason that you overhauled the right steering clutch? Did you use the JD7 gauge to set the pressure plate fingers when you assembled it? As dtoots1 mentioned, try a complete step by step adjustment of the steering clutch and brake. Rule adjustment error or slippage out before tearing it...

Re: fuel additive

Along with what Stan posted. What are you running the fuel in? Where are you located? Are you running a premium off-road or on-road diesel fuel or a bio-diesel blend? Or are you using heating fuel oil? Is the fuel blended for the ambient temperatures? Are you using 5-gallon cans, a transfer tank, or...

Re: John deere 350b only cuts one way

Pulling a lever disengages the steering clutch and applies the brake, the opposite side should continue to drive, to turn the crawler in the direction of the pulled lever. You pulled the left lever, it stopped driving. The right was supposed to keep turning to "push" the crawler to the left. You als...
