Hi guys i was wondering if you could help me...i was back blading and felt the right side dragging...i immediately raised the machine off the ground and released all track tension to see how the tracks moved...There is a lot of resistance on the one side...enough to bog the engine down and when stee...

I built the tool shown in the tec. manual and pounded them out with a sledgehammer also...My father said to wear safety glasses when doing this...and I usually do anyway...sure enough a chunk of pin broke off when I was reinstalling them and went flying somewhere...

I was just checking the part number for this canopy...I saw two different configurations with the same number. AT43162 ??? The one I need has the front rings/isolator brackets running crossways to the machine...same as the track grousers below them...and the back ring/isolator brackets go lengthwise...

Hi Digitup thanks for the offer...Yes I would like the backhoe ROPS with the fold-over hatch if possible...I may have to head down your way this summer to pick up my son in Barrie, anyway. BOB

Hello I am looking for a ROPS to fit my 1978 450C loader/backhoe. It currently has a home made canopy but I'd like to find an original. I'm a bit isolated up north in Ontario...but Minnesota or Wisconsin is close enough to drive to...or I'll just have to pay more for shipping...if anyone knows of an...

I think my 450C originally had a horn too...lets the dump truck driver know when he's full...

Thanks for your input guys...I have contacted a few suppliers for teeth and I think that perhaps I'll try welding on a strip of old snowplow cutting edge...The current edge is pretty blunt and, although the machine has lots of power, I can't help but think a sharper edge would make a considerable di...

Hello Guys....Just welcoming your opinions on fixing up a bucket. My bucket never had teeth and there is only a little more than 1" left from the cutting edge to the seam. How wide is that with a new cutting edge, anyway? I was thinking about finding some aftermarket teeth for it. What style should ...

Just as a follow-up on this issue...my father removed the new injectors and took them in to a diesel shop and got them checked/re-set (found correct pressures in a previous post)...and the machine runs fine now!...Thanks for the help guys! BOB

Hello everyone I have just got my machine back together after 4 months of refurbuishing...mostly U/C, paint etc.. However, now it does not want to start. I replaced the injectors with new aftermarket (RAP) ones. I have plently of fuel all the way up to the injectors...it actually wants to go...it'll...

Hi all...just wondering if anyone knows of an economical replacement for this guage...AT39728...the dealer price is $180...

Thanks for the links...The dealer actually ordered in a product for me even thought he said he wasn't sure what it was...It is nothing special but I suppose it will work...I liked the original stuff...it was nice but there was not much left of it...

Thanks for all the informative replies...I will certainly stick with the higher grade for sure...My dad, who worked for the local CAT dealer most of his life, said all CAT bolts are grade 8...

Any ideas where I can find some foam air gasket material for between the hood and radiator?....Used to be an actual part for the 450C I believe but partslist says to make it out of universal stock item....(1"x2.5"x 31" & 1"x1.5"x60")....JD dealer says he doesn't know where to get it...I live in an i...

OK...thanks for the advice...I'll go with what I've got then....I'm not too experienced at mechanical stuff...usually just bring the broken stuff to my brother and father who are both mechanics...I will have to be sure not to assume things...like a grade 8 being better than a grade 5....sounds good ...
