Evening all. The trusty rusty Hymac bought for £1250 twenty years ago is showing its age after a massive soil and hardcore move for a new house. The front track idler bushes are shot, it's the normal type not the cast shoes and I have the parts manual so know what's what and where. Just wondering if anyone has done this and can offer some pearls of wisdom. It's a split the tracks job so not needing much finesse more brute strength type job.
