NOW SOLD
Triumph pre unit 500cc 5T twin close fin ali engine 1954 with big bearing cases.
This engine is being sold as one for rebuild. However, it has most of the parts needed.
Two main points about this particular engine that make it a little better than most. It has a very nice cylinder head and barrel with the sought-after close fins in ali. It is also a big bearing version.
It has marks from use and will need a good clean. But, the 8 stud head and barrel do not have cracks in the usual places around the stud holes. Have a good look at the images. I can’t see any. Overall, threads look fine. you will need to add some fixings to your shopping list as (for example) there aren’t any for the timing cover. There are no rockers / rocker covers or sump plate.
The numbers are:
- Engine cases: 5T 48139
- Close fin ali Cylinder head: E2679
- Close fin ali Barrels: E2958
- Outer timing cover: E3110
Engine cases: Generally in good condition with matching case halves. The crank is fitted , together with the conrods and pistons. As you can see, the timing gears are fitted. The crank turns smoothly.
Barrels: No fin damage from what I can see. They need a clean externally. The linings look nice and thick. According to my Vernier, they measure 62.10. The pistons don’t have any sizing stamps. I have not removed the barrels to check the pistons. However, see the images down the bore. They look pretty good.
Cylinder head: As you can see, it is still fitted with the valves and springs. It will need a good clean and de-coke. These heads usually suffer from over-tightening the head bolts and resulting in cracks. From what I can see this head is fine. There is one very small fin tip missing on the top of the primary side near the exhaust outlet.
There you have it. A Triumph pre unit 500cc 5T twin close fin ali engine 1954 with big bearing cases ready for someone to rebuild. A rebuilt one of these is now around £2000. This seems very reasonable.
I have a few close fin ali cylinder barrels and heads if you’re just looking for one of them. Let me know.
