GB is not OK!

Read somewhere a while ago that Hepolite has been taken over by Wassell and the pistons they supply are JCC pistons made in Taiwan can anyone confirm this.

Hepolite is just a brand.  Their Bradford factory has been closed for a long time.

Wassell owns the Hepolite brand and they stick it on boxes containing Taiwanese JCC pistons.  They are good pistons and may be better than original British Hepolite.

I don’t know what rings Wassell sell as Hepolite. Their circlips looked dreadful to me and I bought alternative ones from EBay.

Today's work:
Pic 1: Timing side case with new ball and spring fitted to anti wet-sump arrangement. Oil pickup pipe resealed.
Pic 2: Head, (and barrel) masked-up prior to spraying with heatproof paint. Items then baked in the oven, (which made someone rather cross!)
Pic 3: New style sludge trap plug fitted
Pic 4: Valve grinding
Pic 5: Combustion chambers holding petrol
Pic 6: Oil tank, pipes and filter next off for cleaning

I am now in need of a useable conrod. Monday, I'm going to take my worn one to my new friends at Coventry Boring and Metalling and ask them to machine the rod, make a new bush and ream it to fit the Gudgeon Pin for me. I cannot get an oversize bush delivered quickly so I'm hoping that the engineers will be able to modify a stock bush from another source.

PS: I also fitted new seals in the drive side bearing and clutch.

Well, I hope they source decent quality rings as well. I'm not a tearaway these days so anything I put in this engine should be low-stressed.

I have put Hepolite pistons and rings in the SA. They came in the famous box with the fingerprints and all. Clocked up about 300 miles now and they behaved flawlessly.

 GB,

 If you were going to attempt to use that reamer for the little ends:

 A trick I learned a long time ago to help cut down on chatter while using an adjustable reamer:

 Pack the blades full of axle grease, then wrap the whole mess one time around in wax paper.

 The grease dampens out the harmonics, and the wax paper helps keep chips out of the grease just in case you have to adjust and hit it again.

Lee, thanks for that tip. Are you saying you ream with the paper on?

300 whole miles?

[coater87]

 Yup, leave the wax paper on.

 The guy who showed me this was a known trickster, so I automatically thought he was full of B.S.

 There is no doubt its messy, but also no doubt it helps the surface finish too.

Ain't bad in 2 weeks time I guess

At least his bike runs.

Ouch!

Hi GB and All,
If and when using an adjustable reamer, take very small cuts, if the blades are dull it wont take fine cuts so you adjust some more and some more until they dig in and produce a series of ridges 
A spiral fixed size reamer is a better bet, best of all is a Sunnen hone and an experienced operator
A "normal pillar drill" would not be accurate (square) enough to ensure alignment

Valuable information. Thanks.

Cleaned the bores and checked ring gaps today. All rings have a 10 thou gap out of the box.

I also fitted new cam followers to the block.

Moving right along. She'll be back on the road in no time at this rate!
