RE: What have you done today with your Austin Seven - Howard Wright - 14-09-2020

Hi All

I remved and replaced a 1 1/2 crank in a 1 5/16 crankcase many times while I was trial fitting it.  I can think of a lot better words to describe this process.  Unfortunately none will get past the censor ?.

Cheers

Howard

RE: What have you done today with your Austin Seven - Jamie - 14-09-2020

It is reassuring to hear that I am not the only one who found it a job to remve the crankshaft. Much as I am looking forward to getting the engine running, I do not relish putting the thing back in again. Still, I need to sort out replacement bearings first as the roller and ball bearings are rough.

Jamie.

Hi Jamie
Are the bearings really rough or is there a trace of dirt or a brush hair in them? The common failure mode is slight clearance, often largely the result of corrosion more than wear. I would be interested if conventional failure pitted bearings are ever encounterd. Unless rust pitted from long standing

Hello, Bob.

To be honest, I am not sure yet. I need to give them a good clean to check. I plan to use the ultrasonic cleaner to shift any grit and then warm air to dry them out thoroughly.

I'll send out pictures when I have finished the job, but today I am going to make a box to put on the luggage rack into which I will put a pretend shotgun. Then along with owners of Austin Sevens, Morgans and a Marlin or two we will set off on Sunday to watch some modern machinery going up Shelsley. Going hunting, officer, look I am wearing a deerstalker!

RE: What have you done today with your Austin Seven - David.H - 15-09-2020

I have tried to separate the housings from the rims of my rear lights (small round pattern with faceted glass lens) No doubt it is a mix of paint and corrosion, but they are not items to apply much heat to, not can they be gripped in a vice or with giant Sttillsons.....Soaking in penetrating fluid has not had any effect, not careful scraping around the outside visible join. One still has a rubber gasket retaining the lens, the other lens is loose. from a 1929 RK saloon

RE: What have you done today with your Austin Seven - dickie65 - 15-09-2020

I did 5500 Rpm in fourth gear on the way to work at 6.30 this morning. ( Car has electrical rev counter in place of petrol gauge.)
3.25 x 19" tyres with modern sports ratio back axle.
I managed to hold 6000 Rpm in third on a long uphill as well.
The new radiator and four blade fan did the job well.

RE: What have you done today with your Austin Seven - Spex - 15-09-2020

I have been told (by the manufacturer of mine if I remember correctly) to be wary of putting bearings in an ultrasonic cleaner for any period of time, as the constant shaking and hitting can damage the surfaces. I would ask Messers Giggle, Goggle and Gargle first.

When drying don't use the old apprentice trick of spinning with an air gun- with an unloaded bearing rotating at many revs.  the balls can slide smearing the tracks Huh

I haven't heard this- I would think it could take quite a while for an ultrasonic cleaner to cause false brinelling with an unloaded bearing but it could be worth limiting the time.

RE: What have you done today with your Austin Seven - Jamie - 16-09-2020

Thank for the advice and suggestions on cleaning the bearings. I shall pop them in for a short while for a couple of times, turning them between times to expose different areas. I was going to dry them with a fan heater.
