its not been in much slop or concrete and kept fairly clean. Supplier says lack of use
they'd be sealed bearings in there I assume .... quite how lack of use would be a cause would need some serious explaining to me, if they were mineThink on the old forum i had a thread replacing th under carriage on my 1.5t.
Anyway 2 rollers are knackered after 345hrs.
Whats people's thoughts
Yeah you'd think lack of going round and round would extend their lifespan.they'd be sealed bearings in there I assume .... quite how lack of use would be a cause would need some serious explaining to me, if they were mine
Sh*te
How tight is right?
I'd say about right if you do a lot of tracking. Only takes a couple of rocks in the wrong place at the wrong time to seriously weaken the cables.
Large lump of concrete was the issue.
I'd expect a LOT of tracking to wear them down to a point at which grip becomes an issue on slopes or slippery going but not at those hours. For them to snap the wires have to be weakened by corrosion really unless you've missed something going in between the track and undercarriage. For corrosion to be a factor I'd still expect more than a couple of years and yes I've had tracks with cracks/splits in for a long time before any issue.
We had a heavy-handed so-and-so who hammered grease into the tensioner on a Cat 301.8, as soon as he started tracking one of the wires in the nearly new track snapped. I told him to park It out of the way, and as soon as he screwed round the track parted completely. Rubber tracks usually run quite tight, and it’s important to set them exactly how the book says. Some have a mark on the edge that has to be in a certain position when checking and I’ve found from experience if you don’t follow this you can end up with the wrong tension.
Check the handbook or look on line.
As a rule I've found that once correctly tensioned a manual grease gun soon tells you. Not an ideal method obviously your better off checking against handbook. I've actually painted measurement for sag between track and frame onto the back of the plate that covers the grease nipple. Not needed on 8 ton takis mind, hydraulic tensioning (everytime you put into high speed tracking so useful to do so know and again even if you don't need high speed). I don't know why more machines don't have it.
Even more so with a pistol grip type one.
For fuchs sake there's always oneEven more so with a pistol grip type one.
Is this thread going to turn into a which grease gun/battery/manual thread
