Re: drive sproket removal

This is over 56 years of memory talking and may not be accurate. I recall using a bottle jack and chain as a puller to get it off the three dowels after the bolts are loosened a lot but not removed. That and a sledge hammer usually worked, assuming the axle bearings were still good.

Check your boom lockout valve.

Re: 350 steering clutches

No. I meant put an o-ring on the smooth part of the shaft probably inside the "bushing" that the TO rides on. Small drips of oil coming from the quill end will drop onto the bushing instead of following down the driveshaft to the clutch plates.

Re: 350 steering clutches

If the drive shafts stayed readily in the "differential" then you had better check your pilot bearings carefully. Also, I would put an O-ring on the drive shaft on assembly to stop gear oil from traveling down the shaft, even with new seals.

Re: 350 steering clutches

Never tried it that way but, if it works, why not! I leave the clutch on the final, pull the driveshaft (made a fixture to clamp on the driveshaft and pry it out), then remove the rods and roll/drag the final out supported by boards.

Re: 1960 John Deere 440 crawler help

Not sure how we got from "pops out of gear" to "clutch is shot" but Lavoy is the best source of quality parts.

Re: 1960 John Deere 440 crawler help

I assume you mean it is grinding in neutral with the cover on. And by grinding you mean like putting it in gear with the clutch out. You need to see if any shaft is vertically or horizontally "loose". The best way to do this is with a hook bent into a welding rod. Hook each shaft (with the cover off...

Re: 40c shifter

Unless you are trying to keep it "original" you can replace the whole cover with a "caged" shifter off a 420 4 speed. Some interference with clutch handles going into one gear (fourth as I recall) but reliably finds all the gears, including first!

Re: 350 JD crawler loader bolts?

On a dozer they would be in the front (bottom) holes on the final drive. Don't know about loader but suspect the same.

Just out of curiosity - why do you need to replace the whole engine?

Re: John Deere 350b reverse problems

DO NOT MOVE the dozer under power, and tow it judiciously. Sounds like a bearing spun out in tranny. The fact that the gear shift locks up tells you it is not the reverser. Using it may shell out many gears, including ring gear and pinion.

Re: Clanking trans

Sorry, but the only thing I know that turns at the speed of the input shaft IS that shaft. It runs all the way to the flywheel, so the sound may be originating elsewhere. BTW, there are two revolutions of the input shaft for every "pop". Don't know why it doesn't change with 1,2, and R and is not th...

Re: New - Just bought a JD 430

Two things to check. Did you remove the input elbow from the carburetor and clean that screen? And did you open the load jet on the carb one quarter turn to see if that makes a difference?

Re: Clanking trans

Is the clanking related to ground speed or does it change with changing gears (in other words: Is it related to ring gear or transmission)? If it is related to ground speed then the problem is probably in the ring gear. If it changes with the gears it is probably transmission. If it is transmission ...
