Hi all

Going to whip the gearbox off for a rebuild soon as the input shaft bearing has developed a whine ( definitely not the clutch release bearing unfortunately )

Is this kit from Rockauto any good or would any of you have a suggestion for a better kit
Thanks

Vic

Hi Vic,

You have to convert the bearings at the front of the input shaft to closed bearings, then there's no problem. You can make a puller for this with the silent block of the gearbox suspension and 2 long gearbox connecting bolts. The open bearings are flushed by the swarf abrasion and start to become noisy.

Good advice Thomas thank you. Do you have a recommendation for a supplier or the sealed bearings ?

Thanks

Vic

Unfortunately, the conversion was carried out over 30 years ago. The gearbox has not caused any problems since the long time and the many kilometers. I had the bearings from the German needle bearing factory "INA" in Lahr. The town where Felix Wankel was born.
But I would order Japanese NSK Corporation bearings, they are supposed to be the best quality. The dimensions are etched on the bearings or you can measure them.

I've had think link saved in my bookmarks for years. Never used it though
