Well if all goes as normal 🤪 they will assign an accountant as the business lead for the entire company. Kind of like Boeing aircraft did, talk about loss of quality.

Did the price of spares just jump up?

I think so!

Triumph GT6, Spitfire, TR7 rear differential Cross shafts. PN UKC4493 I have installed and sold a few of these Cross shafts and they really help tighten the planetary gear section. Rock-Well 60 grade polished bearing shafts. New Better than O.E.M.. These are impossible to find anywhere else! 63.47 GBP

 I had to custom order more than I needed for my cars and now they are to good to sit on the shelf. Will consider trades towards the following GT6 Mk1:  144627 1st gear,  132097 3rd gear, 144580 Rev Gear 12 tooth, "No Bastuck Trans Parts"    

Stock Part

Hi Ian

As you requested.

The bushings are 52100 material with a hardness of 62/64Rc. verses the OEM 48/52Rc. They are custom ground here in the USA and have a wall thickness of .036" with an ID of .8438" This allows for the use of standard spec needle bearings and lay shafts. The newly ground bearing bore is sized for a light bushing press fit with Loctite #648.

Since most machine shops wont touch automotive gear parts it was done by me for my MK1 GT6 transmissions and because of the poor consistency on gear OD run out its wasn't hard to improve the over all gear during the re-boring process.

This was a year long development project for me and I had more bushings made than I needed so extra laygears repairs are in the future to help pay for the extra tooling purchaesed for my lathe.

Regards,

Rob   

Still looking P/N 212993 cores.

Greetings Steve

Looking for lay-gear cores P/N 212993 for re-bushing the needle bearing area.

Rob

Found my solution to fixing lay-gear P/N 212993.  Are others lay-gears that are worth saving ?

Regards,

Rob

Ah yes sorry for the confusion.  I'm still planning to go Mk1 GT6 Gear box and in fact I may have a source for new OD main shafts. But also considering sleeving the tips of some old ones.  Bastuck Mainshaft G31SPTMK4 OD shown on the left is close to OEM on right. The only difference being the 3rd gear Circlip width and the 2nd & 3rd Gear bushing journal being a few thousands over the OEM size. I suspect that a Mk4 bushing and Circlip could get it all pulled to gather. Worst case I would need to open the bushing IDs and stack 2 Circlips.

You mentioned the helix angle under 2nd gear on the GT6 main shaft. Isn't that helix only for 3rd & 4th gear synchro hub? 2nd gear bushing covers it so it does nothing for 2nd gear.  By the way does anyone have any experience with BASTUCK main shafts?

Thx. Rob

I don't have a phone number or email for Mike and cant even message him though the club system!

Being a rookie rated member limits my use of this site option.   

Glad to hear you think Mike is still a prospect.

They are KC 103, 104, & 500, SN boxes all 21 tooth so repair or used p/n212993 is the way to go. I wish on finding a NOS. 🤩

It seems I cant reach out to Mike Papworth on the lay gear until I get at lease 10 qualifying club communications. 😴

My Lay Gear is no better than Grahams. Its the winter project to complete this 3 rail D/OD gear box. Would like to find a replacement or the parts and knowledge to repair. it. 

Greetings glang

Very interested your Lay gear project. Did you complete it yet?

Rob.

Thanks for the reply Mikey if I get no direct part replys I will reach out him. I know many of us are busy tinkering.

I have a NOS inboard GT6 shaft PN# 214623 I'm Looking for a Lay gear with a 21 tooth rev gear

I have been told that its possible to also find reworked lay gears. that would be acceptable as well.  Interested if Mike Papworth is still installing hardened steel sleeves that also allow longer rollers to be used.
