Re: Cross drilled crank

I would let it go to anyone who wanted it, for a suitable charitable donation.
Despite it's credentials, it is too worn for my racing usage.

As we may assume that it's in its original block, transport would change from weighty to massive!
Glad to discuss with any interested person.

Re: Cross drilled crank

The archivists over on TRR have found that:

All TR4s were cross drilled, but that's not a crank like this!

All TR5s were cross drilled.

TR6s were cross drilled, up to CP 52329

2500 engines were cross drilled until MG 10323

and they have original Triumph dealer Newsletters to prove it!

So this ...

Cross drilled crank

I have found a six cylinder, 2.5L Triumph engine with a cross drilled crank. The block has the number MG 7845HE, which makes it an early 2500 saloon engine.
The big end journals have brass orifices fitted to the ends of the diagonal drillings from the mains, and I am informed that this was the ...

All-Triumph Relay Race team

All,
Last year, I tried to form an All-Triumph team to enter the Birkett Relay race, but the Birkett has has moved towards modern cars, with higher speeds and different attitudes to racing. So I have been looking for another event that would be more suitable for an All-Triumph Relay Team – and I ...

All,
Delighted to see that Dizzie got it right!
And I hope no one offended by my \'little used\'. 
Now, anyone help with my early engine block enquiry?

Sorbs,
there is a screw, with a lock nut, on the end of the rocker that bears on the push rod - you use it to adjust the distance between the other end and the valve tip.  If that nut gets loose, it would be possible for the screw to unscrew and fall into the depths of the engine.  But I ...

All,
Over on the Club Triumph MsB, a member wants to fit an early&nbsp;2000 engine to a 1600 Vitesse.&nbsp; The usual way of doing this is to use the four stud engine mount position on the block casting, but this 2000 engine has been cast for only three studs!&nbsp; See: <A> http://club.triumph.org ...
