MG Midget and Sprite Technical - Bearing sizes
|I have pulled out my centre main to check and renew - just wondered if there would be any markings to show if its std size of oversize etc..|
The ony markings I can see are
5106 on one end and 149082 on the other - both on the back ...
I assume they are std ? Be grateful if someone could confirm
|ps bearing surface is worn as pic below..
|I can't answer your question John, but those that can will need to know which engine you have. |
|If they're undersize, they are normally stamped 010, or 020, for whatever size they are.|
If standard and original, likely as not they will not say anything. If standard and replacement, they are often stamped STD.
What does the journal look like?
|On to the engine now John? We seem to be undertaking exactly the same projects at opposite ends of the UK!|
I can't even get my head off tho. Taken all the studs out and everything it it will not budge! Gonna buy a big mallet this coming week. :-)

|Mike its a 1500 version...|
The journals look pretty good to me - considering it had been laid up for nearly 20 years..
I had expected it may have been reground or something -but at 76000 miles it looks pretty good - and the shells have no signs of anything indicating them being undersized bearings ( as you say Dave 10, 20 or something)
There is a slight discolouration down the centre of the journal where old oil left a deposit - but it rubs off with finger pressure. Otherwise no marks visible so far. Just centre cap off so far - working on getting the crank shaft pulley nut off.. But it extremely stuborn.. What socket size is it? anyone know - I am using a large adjustable - not really right for the job !
My head didn't want to come off either Malcolm - I think I levered it off against something protruding from the casting somewhere.. You could try turning it over, the compression may help pop it off ( plugs in !)...
If not try lifting the engine weight via the cylinder head rocker shaft bolts ( the ones that don't go right through) Attach your crane /hoist through some lifting eyes and lift the whole thing up a half an inch - that should do it!
if you can change that duplicate email address to 'View vehicle profile' then more will look there - not all as some don't want to anyway and/or can't be bothered, which is their right if they don't want to
|Can't seem to get rid of the email tag attached to the view vehicle ....|
got it now I think..
|What email tag?|
|Malcolm - what is your estimated completion date for your car ?|
I have a site I am building up ( just for the fun of it) link
Take a look and let me know of any suggestions.. I know the layout is pants -but its free..
Fancy a challenge - who can get on the road MOT'ed and running first?
