Spigot bearing

[phillpot]

Anyone got the dimensions please ?

15mm ID x 21mm OD seems to be common to a lot of Fords ?

ETA, just thought, I've got a spare gearbox, just had a measure of first motion shaft and the 15mm bit is looking good.

Did I see someone on here a while back had made a removal tool from a Rawlbolt?

Probably no help whatsoever but I had an old 2.3 Grandad years back - I changed the engine for another one and the opening in the end of the crank was a different diameter. I can't be sure but the original engine was 21mm I think - and the replacement was 19mm, as you said I think the gearbox input shaft was 15mm. I ended up having to use a bronze bush instead of a bearing but it seemed to work till I part exchanged it

I think the replacement engine I fitted may have been from an older 4 speed box grandad but don't know for sure.

Phillpot...it was deadspider who did that...search for his posts, but I've not seen Andy for a while....

I'll dig out my reciept from Burton Power when I did mine last year

Hello Tony

Nice to meet you at SCH,glad to hear the box is out and the puller worked.

The clutch came as a three part kit,

QH
QKT 2030AF
Other numbers/letters on the box were Eqiv MHK 52030.

The spigot bearing is


Still not quite sure how I did get the box out on my own,but I think my adjustable beer belly helped

Good luck getting it all back together. Just make sure you compare clutches the first two offered to me were slightly different to the one I had.

Cheers Andy

Gearbox back in and all running fine just in time for SCH

I found this post most informative and have remade the end of slave cylinder pushrod,sits snugly now in the thrust plate.

Here are a few pics.

I made spigot bearing puller,worked a treat (thanks Mark)







sorry none of the gearbox etc going back in but if your at SCH tommorrow I will tell you all about it

Mike, don't know if this will help but when I worked on Rover V8 engines we used to 'Hydraulic' the spigot bearings out to change them.
Fill the hole in the end of the crank as much as you can with some form of grease. Then find a piece of bar which matches the spigot bush internal diameter (15mm from what you say).
Place the bar into the spigot bush, won't go in too far as the grease will stop it. Then tap the end of the bar with a medium sized persuading tool (or a hammer if you have one).
The pressure built up in the grease will force the spigot bush out, onto the bar.

I thought the guy who showed me this was having a laugh (I was only an apprentice). but it actually works a treat.

Thanks Bob, never seen it done, but was also told that way many years ago.

The Rawlblot and bracket looks a bit less messy so (when I get around to it) will try that first but have the grease and big hammer in reserve

Hello Mike,

I tried the hydraulic method but gave up after being splatted in grease a couple of times.

I found that the spigot bearing needed pulling out as it was stuck fast.

I tried this numerous times with no success before I made the rawl bolt puller that Lou copied. The full make up is on my website here

Could be that the "grease 'n hammer" works better with larger diameter bearings like these used on older Fords

The Alternative Parts List covers the crankshaft spigot bearing and gives the dimensions, and a contact from which the bearings can be obtained on next day delivery. There is also a link to previous PH posts on this issue.

Thanks, didn't think to look there.
But not totally clear ? quotes 2.8 engine and says later engines may be larger ?

Hope not, I've orderd the 15/21mm bearing

[phillpot]

Slipped the gearbox out yesterday, changed the thrust bearing, hopefully sorted oil leak and while it was out changed the spigot bearing.

Thanks for the removal tool idea, worked a treat !

Old bearing still attached in photo ........

Has anyone ever has a spigot bearing fail?
I've never heard of one failing, at the end of the day it doesn't get much load most of the time, and when you are driving along normally it isn't even spinning.
Just curious I can't disagree that its good practice to change it although the little bugger sounds like fun.

There was a thread on this a while back, it gave a similar effect to a clutch failure IIRC and it occurred in France to the poor unfortunate
