¿ªÔÆÌåÓýthrust washer, thrust bearing, thrust washer, spring washer, anodized donut, and finally the clutch knob. *** I much prefer thrust washer, thrust bearing, thrust washer, anodized donut, spring washer, and finally the clutch knob. This allows the ¡°anodized donut¡± to help keep dust and dirt out of the thrust bearings and provides an even load on the thrust washer.. Pretty sure this was the ¡°preferred¡± method from Winslow astronomy.. Someone knows.. or can say I am crazy..

Since yours is even older I would recommend replacing all bearings and thrust washers, even the needle bearings inside. You will need a bearing puller to get to these latter ones as it's near impossible to get any tool in behind them. From the pics you are showing, I assume you are wanting to replace the lower thrust washer assembly which goes in the following order - thrust washer, thrust bearing, thrust washer, spring washer, anodized donut, and finally the clutch knob. If you send me a PM I can give you a list of all the parts you need and where to get them. I also can supply a lubricants sampler, with enough original Losmandy greases to redo the mount. ? There may be nothing wrong with the original stainless worms, which I just reused on my mount. It all depends on their peak to peak error in arcseconds; mine were around 10-12. Between using PPEC in PHD2 and Howard Dutton's PEC correction tool, you get can your guiding errors down to pretty low numbers. My worm connects directly to the motor via a bellows coupler, with the right angle aluminum stock as already mentioned holding the motors in place. But you should also do some type of Belleville washer upgrade on the far side block to keep the bearings compressed and the 76s error to a minimum.? ? Please let me know if I can help further. ?
