Workshop in Action: Caterpillar 980G Repair

August 25, 2010

This week we are attending to some faults on a Caterpillar 980G loading shovel.  The hitch bearings are badly worn and we have to ‘line-bore’ the trunion plates to accept our manufactured weld-in bushes.  When this is finished the replaceable bushes and bearings can be fitted.  All-in-all a time-consuming and expensive repair, this could have been avoided with a more diligent maintainance regime.

March 17, 2010

Week 7 of the restoration, not the most exciting part of the restoration, but every small gear and bearing counts if we want the finished machine to be perfect!

Not much interest, but proof that we have been doing something this week!!

BTD20 Gears and Bearings

A pallet-full of very healthy gears and bearings to be re-installed when bottom shaft returns from having its gears press-fitted.

As I write there are two engineers in the workshop working on the BTD20  right now! So hopefully week 8 will be much more exciting!
