Cat 963 repairs

[Spyros33]

The shaft was worn too so it had to come out for machining. Man that thing was hard to remove! There were two threaded holes on the flange that are supposed to eject the shaft by inserting two screws but that wasnt enough. Had to use some Wedges and a lot of brute force!

Ιdler needs new bushings


That bearing assembly was also really Hard to remove and even harder to unscrew the flange in order to get that bearing out

11 out of 12 bottom rollers were shot

Starting from the rear side, the rollers on one side were S-D-S-D-D-D while on the other side
Were S-D-S-D-D-D.
I think the second is the correct sequence. Can someone confirm?

According to the info I can see there should be 4 singles and 2 doubles on each side.
Sequence is called out as S - D - S - S - D - S
Usually a double should never be installed immediately next to either the sprocket or to the idler.

Yours should have a single next to the front idler and the rest are correct.
Usually roller position is called out from the front to the back S-D-D-S-D-S.

Hi guys,
Things are going pretty slow due to lack of time. We started the assembly today and hopefully we will finish in the next weeks
New rollers, repaired idlers and new bucket blade and teeth

The old teeth are just perfect for my 955 bucket

Spyros curious why you are taking the teeth off and putting a smooth cutting edge on that 963?

 

[Spyros33]

We have put new teeth on as well. The old edge was worn out so we change the whole thing

Great to watch you work Spyros! In my good days I would have had trouble keeping up. Keep those pictures coming!

New sprocket segments
Undercarriage support shaft was welded and machined down to proper diameter.
