Volvo L220 Overhaul Update

July 3, 2012

We had completed the bulk of the work on this shovel, when we undertook a large service before delivery.

An oil change from the rear differential revealed it was badly contaminated with steel and a test drive around the yard confirmed our suspicion that there was unacceptable wear.

We are refurbishing the unit to our customer’s instruction. Pictures show some of the wear.

We have been awarded the work to completely overhaul the engine and transmission on two of these massive machines.

Reassembly of the transmission using a new casing (there were cracks in the original) cleanliness and attention to detail are critical.

Volvo TD122 engine ready to fit. We have rebuilt it as a KLE version which is the low emissions permutation.

Following the engine and transmission refit, the rest of the machine will have a thorough inspection and repairs will be undertaken as necessary with the owners approval. When this one is finished it will be taken back to the quarry and the second machine will arrive at our workshops for similar treatment.

Transmission Failure

December 9, 2009

We are now actively encouraging our regular customers to overhaul their transmissions at 10000-12000hrs before risking expensive transmission failure.

Here is a picture of A30c transmission we overhauled recently at 12000hrs

This must be the epitome of impeccable timing, although the unit was functioning normally it was found to have severe damage to the pump.  The unit would probably have only lasted a few more service hours when certain expensive failure would have occurred. The customer was pleased he made the decision to overhaul when he did as he saved about £3500!!!

If your pump is getting to 10000hrs strict attention to detail is required on the inside of the oil strainers/filters, this will give an insight as to the true condition of the transmission
