Neils 1978 CB550 F2 Project - Newbie Let Loose

<< < (15/16) > >>

McCabe-Thiele (Ted):
In defence of taper roller kits I have found there has been an improvement in the last couple of years. I've had a good experience with Pyramid Parts Kits.

That said I would probably stick with original ball bearings if I have a next time project. My 400 NA Superdream project has been on hold since Wendy's stroke last April. I'm planning to work on the SD again in April/May depending on the weather.👍

Like Ken my own  health is only just returning to a point where work on the bike is possible. I've lost a good three and a half stone in weight since last July, My arm muscles have gone in the process so it's a case of the mind is willing but the body less so. Lol

SumpMagnet:
Had exactly the same experience as Dave fitting a taper roller kit. The beasrings had hte correct internal and external diameters, but the 'stack' was too tall, and barely any thread was poking through to tighten down the castle nuts.
REverted back to a ball bearing kit which had no issues.

Back in the day, I fitted many a taper roller kit, but for whatever reason, the currently available kits do not seem to have the right dimensions in a lot of cases

Murf:
I like taper head bearings and feel they are the best so I bought a taper bearing kit for my 550, I had problems fitting it, same as others have said ‘to high not enough thread left at the top’  not protected from elements. I decided original setup had been ok for 50 years so got new bearings and went back to that, everything fits as it should no problems. So my advise,  take the easy path.

McCabe-Thiele (Ted):
My 500 already had a taper roller set fitted by the PO, due to water ingress and some standing there was rust on them so I replaced them with a Pyramid set that were the same dimensions (including height). As has been mentioned the bearings stack height needs to be the same or less than the original bearings to avoid thread loss.

Qucick Update 1st April

been a while since i gave an update.

The bike is now completely dismantled. Discovered that the swing arm was rot, so purchased second hand one from ebay, same for the steering yoke which had some damage, so i replaced that.

The cylinders have been returned, bored out with new pistons and rings.

All engine casings have been prepped for paint - just need some warmer weather before I tackle that.

The frame and other bits are with the powder coater, and I should have them back in a few weeks.

I'm now systematically going through the boxes, cleaning and repairing where needed. Finding other bits that will need paint, which I'll do myself.

I'm now tackling the wiring harness. The bike probably had electrical problems, as many connections were poor or corroded, so cleaned and replaced where necessary.

My major achievement has been building a new fuse box, with ATC/ATO fuses. Issues with extortionate postal charges from the states made it a no-go for Hondaman, so with his direction, I have built my own. Parts cost about £10, so worth a try! For the eagle-eyed, the fuses are not the final rated ones, just what came with the unit.
