JDcrawlers Messageboard

Okay well thank you everybody for your help, it sounds like I should just leave it together and get that bottom bolt out and remove it intact. I'll have another go it once it stops raining. Is a sloppy mess outside now, rain on top of 3' of snow. The tin roof on the shop shed it's snow taking out th...

Thanks boys. Well there's 3' of snow on the ground and it's warming and melting and dripping all over the machine so going under the machine is out of the question :cry: I don't know how I would get in there with the JD wrench, I looked at it and I'm not sure how it would help. Today I was using a s...

Tried to get the faulty starter out of my '81 450C crawler today, no luck, well 50% luck. I got the top bolt out easy, but for the life of me, I couldn't get the bottom bolt out, my arm just can't get down there to get the swivel socket on the nut. So I am wondering if the starter can be dismantled ...

Hi all, So I need a new starter for my 1981 450C, and I want to get one of the gear reduction starters, and I have decided to get it from Amazon as I am in Canada and ordering directly from the US is a hassle. I have been happy with DB electrical as they supplied the starter for my 350, but for the ...

It's up to 0 today and thought I would go start it and move it to a good place to install the heater this week, but now, the starter is making some serious groaning noises and light smoke is coming out of it. So I guess despite it having new brushes and looking good and clean inside, it has other is...

Thanks Bruce, didn't know that. So it's thermosiphon like my MC is.

I'll read the directions when it arrives, but now I have a better understanding of its' principle.

Appreciate it.

Cheers

Drag on a 450 is not much of an issue if your clutch is working properly and stepping it down all the way. The clutch pedal cuts off oil to the transmission for the first portion of travel, then activates the dry clutch behind the engine. So only spinning the engine and hydraulic pump. Our 450C loa...

For best results, port from lowest possible point to highest. There should be a block drain somewhere on the side of the block. Put a hose barb there, and what I have done in the past on 350's is put a TEE where the temp sender goes in the back of the head. Doing it this way will flow heated water ...

That's what I found as well, couldn't see anything in the parts breakdown, at least at the front of the engine.

Thanks Jim.

Still trying to get my 450C started in the cold... On my 350 there is a hydraulic pump disconnect on the front of the engine. My 450B service manual shows a pump disconnect, but I don't have the 450C manual yet...is there a disconnect on the 450C? If so where? Back to work...thinking of pulling of t...

I decided to order the KATS 13080 it's an 850 watt heater like pictured above. The 1000W was out of stock. By the time it gets here the cold snap will be over and I can install it in relative comfort. Thanks for all the ideas. Cheers PS it still won't start, even with 250 W air drier heaters under a...

Just left of Vernon, in Salmon Valley. Not sunny now, just cold, imagine you are about -28 or so??

Thanks Jim and Sam, Both helpful suggestions. I have a wifi outlet I was wondering what to do with, now I know, cool. And Sam, I haven't done anything to this machine since I bought it, so I have no idea what oil is in it etc. I checked the air cleaner this morning but otherwise, I need to do a full...

Thanks Jim, Appreciate the pictures. I had a look at mine today and your first picture setup would work, I have the same ports, but I also found the thermostat housing has a 1/2" pipe thread plug which I could remove and use that port. There is also about a 3/4" pipe thread plug at the back of the h...

Hi guys, My 450C has been pressed into service for snow removal on our property this year as it's a bit too much for the skid steer...but my 1981 450C doesn't like to start when it's -20C outside. I have looked around the engine and don't see any signs of a coolant heater. My 350 has an inline heate...
