Piston Identification


Recommended Posts

Hi Knowledgeable Folk,

 

I have been given a number of parts, most of which are TR4. I'll post a list in a bit in case anyone needs them and is willing to source (free, except for shipping) from Canada!

 

But first, I need to confirm the set of pistons (and liners) that came in the box. They are used, and the pistons have the following identification marks stamped on them:

 

BHB (in a circle)

205498

M62

2

1 (Note: the 2 and the 1 may be related, but aren't quite the same size or same orientation, but they are fairly close to each other)

 

If this isn't enough information, I can post a photo, but thought I'd try just the numbers first...

 

Cheers,

Tim

I might have a friend who could use these in a rebuild, Tim. I'll check over the next hour or so and let ya know.

Yup the only real concern is probably the potential for a broken ring groove. These'll likely be running in a Doretti before the snow falls.

Think you will find the pistons maybe oval.

Well I took the original pistons and liners out of my 4a engine (with pretty high mileage on them) and gave them to one of our club members who was doing a budget rebuild of his TR4 engine and they have lasted him another 21 yrs with a 90 turn and a re-ring.

Low use as most cars get you are suspending the inevitable.

I think we can say that about any collector's car, and it's probably true for every car the day they leave the dealer's lot!

In days gone by I knew of more than a few wet liner TR and Standard engines that had liners turned and turned again, rehoned with oversize rings, etc etc. Some of them covered six figure mileages, and I can think of one Vanguard estate (a farmer's truck) that had clocked quarter of a million on its rotated components . . . . .

 

Cheers

Nope they have done another 50K plus since.
