JD 644 A Starts runs for a few seconds and shuts down

This 1972 JD Payloader will start and run for a short time then shut down like it ran out of fuel. Other times it will start up and run fine. But having more trouble with the start and shut down than I have in the past.
Reading some forums it sounds like it may be the--MOUSE TERD Problem--where the PELLATHANE RING fails and plugs the return fuel line. Where do I look to see if the MTERDS are present. No window to look thru on this Stanadyne pump.

Or could it be an other problem. When it starts and runs it has a lot of power.

Fuel Problem

We have a Volvo 110F S/N VCEL110FK00061788. If it sets for 24 hours or more it will not start unless you prime the fuel system.
We have changed the check valve/fuel filter base and add a check valve furnished by the dealer and still acts the same way.
I wonder if the main fuel pump is the issue?
IF it is cranked without priming it will throw a low pressure on the fuel rail code.
Thanks for any help,
Rick

Volvo L70 Intermitant Brake Failure

Hi All


Every so often I get brake failure on my L70 loader. The gauge drops to zero and the pedal has nothing. After a while (sometimes a day) the gauge will rise again and we have a pedal.

I think they're hydraulically ran, but wouldn't have a clue where to start. Obviously something sticking somewhere. Anyone got a clue?


Cheers

Hi, I am curious what model this Michigan heavy loader could be?

Here you can see an image gallery with a few images of it:
http://bayimg.com/album/oaAnKAAAc

I'd say maybe a 75 ? But in order to be certain I'm asking you. Where on this machine would I find the type plate, serial number or something to identify it properly. All them stickers have come off.

Appreciate your help

CAT 924 G problems with the gearbox

Hello,

maybe someone can help me here. I bought a 924 G Cat for our farm over here and I noticed that the machine only changes speed on the road (manually 1 to 4, not automatically), when the AUTOSHIFT button is pressed. If the Autoshift button is not pressed, the machine goes very slow in all 4 gears, maybe 10 kmh. What could be wrong with the transmission? I also work with the autoshift button pressed in first or second gear.

Thanks for help!

Holy metallic mess !!

Cleaned out the rear diff housing on the 644E, brake plate completely worn away and milled into iron grease.. Scraped it all out by hand and then filled the diff housing with diesel, halfway, then let the gears spin for a while, did that twice to rinse out all the crap. Axle bearings are shot but the differential bearings and gears don't look bad at all. More inspections later.

I have an '86 JD 544d...can't seem to find an overflow bottle for it, what's a good alternative?

I live in northern ontario so no close salvage yards....just something dirt simple, I'm worried about volume more than anything

Thanks!

If you guys where gonna buy a new wheel loader brand did not matter. The job of the loader is loading, unloading logs, wood chips, and other general plant work. all brands around offer great dealer support it just comes down to what would you rather own.

Case 621C instrument cluster problem

Hi Guys, My 621c instrument cluster (part no.278823A4) has gone blank also disabling trans and bucket controls. Engine starts and runs. Instrument cluster will light all readouts and warning lights when program switch is pushed, will also show correct readouts of oil press, temp, trans selection etc when program switch is held down but won't allow trans or bucket movement. Once program switch is released, screen goes blank. Buzzer sounds continious. Fuses, relays, earths all checked, cleaned and good. Power and earths to IC are good. Case tech manual resolution if power to pin 1 and 2 on IC is good (which it is) with blank screen and no trans/hyd controls is to replace IC which costs $5000. I have to order this from USA at my risk, if it doesnt fix it, tough luck. Has anyone seen this and does it sound right? Instrument cluster does contain computer that controls/overrides trans/hydraulics. Machine is very tidy and in excellent order with 5700 hours. Before this everything worked perfect.
If anyone can confirm this would be much appreciated

John Deere 544A won't move now

I got a 544A running today that has sat for a few years. I had to put 5 gallons of fluid in transmission to fill it she has some small leaks around some plates and gaskets.
My problem is it went forward and backwards fine until I used the left pedal to stop it cause I needed to blow up a tires and now it will not move forward or reverse and the transmission pressure gauge does not go up now.
Could the clutch cutoff be stuck?

My book says to use JD 303 SPECIAL-PURPOSE OIL-----That oil is a 20 weight oil---I think----. I usually use 80-90 weight in my big tractors in the punkins.
Is this light weight oil OK for a heavy payloader???????????????

Volvo l70c ring gear

Hi about 6 months ago i fitted a starter ring gear to a volvo l70c for a customer of mine. It had broken and missing teeth. It was the first job i did for them so i dont know much history of it except they said it chewed threw a few starters. All went well 6 months down the road the new ring gear is the same if not worse id estimate that half the teeth are missing. The pinion on the starter doesnt look too bad but i dont know what else could be causing it? I found a loose connection on the starter that if wiggled around it would engage the starter so i think this might be the problem but the fact that the pinoion isint too badly marked is throwing me off can anybody shed any light on it? It was a genuine volvo ring gear and the starter has the correct number of teeth on the pinion.
