Gearbox layshaft thrust washer spec

[velosolex50]

Part no 154544 listed as NLA on Paddocks, rear washer for layshaft thrust bearing, early car.
It's missing on my car, I have a g box rebuild in progress, can anyone tell me the thickness/material, or better still sell me a spare?
Thanks

SOCTFL Gearbox Thrust Washer Project Complete

During 2011 SOC Spares researched the availability of the Gearbox Thrust Washer, Part Number 154554, which almost always needs replacing when repairs or overhauls are undertaken. The location of this part is shown in the attached thumbnail. The findings were that the part was in short supply and was resulting in gearboxes from the Triumph 2000/2500/2.5 being fitted as a substitution for the Stag unit. In addition there was a concern that Stag gearboxes were being scrapped because they couldn't be repaired.

The Triumph 2000/2500/2.5 substitution gives satisfactory performance in the short term but the 2000/2500.2.5 gearbox is not designed to handle the higher torque produced by the Stag engine.

SOCTFL was able to introduced SOC Spares to a manufacturing company that is able to make new parts to the original design, and provided an interest free loan sufficient to fund the production of an initial batch. The is being repayed from sales of the initial batch such that SOC Spares remains in a cash positive position. When the loan has been repayed the funds will be recycled through further projects.

SOC Spares is making the new Gearbox Thrust Washers available through the trade. However, if SOC members are unable to obtain one from their preferred retailer please contact the SOCTFL Chairman for further assistance - contact details are given on page two of the SOC Magazine.

Hi Philip,

This, and your other recent posts on behalf of SOCTFL, show a step-change in information and feedback that is much appreciated by the membership. Although SOCTFL has done excellent work on behalf of Stag owners everywhere, the progress reports and feedback have, sadly, been poor.

I see that the SOCTFL website (www.soctfl.co.uk) has been updated as well. Thanks.

Now all we need is the SOCTFL section in the Member's pages of the main SOC website to be updated as it still shows a report from Mike Fisher dated 2007. Although much of this is still relevant, it could do with updating, or a referral to the SOCTFL website.

Many thanks, and we look forward to regular information.

I agree wholeheartedly! The status reports are not only good factual information, it's also interesting to see what is going on behind the scenes.

Philip,

are these washers now available? My one is pitted and I've tried everywhere to get a better secondhand one. LD Parts now list a new remanufactured item but Peter has informed me that they also have surface rust and that they need additional machining to fit the Stag, so I guess these aren't the SOCTFL ones you mention.

No idea. Go to the SOC homepage and click on About the Club and select SOCTFL and it tells you MORE DETAILS OF WHAT IS AVAILABLE IS IN THE MEMBERS AREA OF THE WEBSITE. Log into the Members Area and it refers you to www.soctfl.co.uk. That website hasn't been updated since February 2013 and there is no mention of the thrust bearings.

I sent a PM to SOCTFL last week mentioning the thread about ignition switch/locks, but haven't even had an acknowledgement.

Anyone got any views if I should refit this washer with the pitting shown or wait for an SOCTFL solution?

I'm also chasing a NOS one in Australia, but Lord knows when that might arrive in Germany!

I came across this problem a few years ago and ended up fitting two saloon type thrust washers on top of each other to give me the correct end float on the layshaft.

I cannot for the life of me remember which car I fitted with this box, I know it is not in the TR as that has had the same box for donkeys years.

Significantly, the very early 4 speed box that came with the very early engine in my project car only had a plain thrust washer, it turned out the casing was from a mk1 saloon so this type of substitution has been going on for years!

Peter has just got back to me and indeed, the ones he stocks are the SOCTFL funded ones. Not so good if they don't fit the Stag. I've ordered one up and my gearbox is still in bits so I'll check it for size and report back.

Drew, and others. On behalf of SOCTFL, there has indeed been a mistake made here. We now know that the shaft that was supplied to size up these thrust washers was measured at the wrong end, so apologies to all concerned. The existing stock are now all being corrected, and will soon be available again. If anyone has an incorrect one, please return it to your supplier for replacement. Lingen.

Dave. Sorry you haven't had a reply about the steering locks, so how about this one. There was an independent project to get them repaired some years ago, but it never took off. Nearly all the locks seemed to have the same fault, and the broken component could be remanufactured, but finding a suitable locksmith to strip and rebuild them was the stumbling block. Also at that time, the demand for them was not all that great. Perhaps it is now time to look at the project again. I did have a poke around on the "Used parts" stalls last Sunday at North Weald, and found at least half a dozen, all with their keys, and appearing to work properly, so there are still some available for the time being.

Hello Dave, I have posted an update on steering locks in the thread "Jammed ignition barrel - help!" and have copied it here for convenience

Current Problem with Availability of Part

As long ago as 2002 SOCTFL identified that when existing “new old stocks” of Steering Locks are exhausted there is no longer any prospect of re-supply by the original manufacturer. This was confirmed in discussion with the Triumph Dolomite Club and Triumph 2000/2500/2.5 Register whose models also use this part. Both clubs have expressed an interest in the outcome of this project and there is an opportunity for the Stag Owners Club to help maintain the future supply of this part for the wider Triumph community.

Proposed Solution for Reconditioning

Initial investigations by SOCTFL, subsequently taken up by SOC Member A N Other, established that it is viable to recondition failed steering locks on a service exchange basis. Investigation of failure modes showed that it will be necessary to remanufacture a component part known as the “actuator”. Other parts, which fail less often and show less wear, can be recovered from locks that are unsuitable for reconditioning.

The actuator was originally cast in low strength Mazak and is subject to frequent wear and failure. To mitigate this it was proposed that the remanufactured actuator be produced as an investment casting in stainless steel. The investment casting approach achieves cost effective small batch production with relatively low tooling cost.

During SOCTFL’s initial investigation a preferred supplier was identified. A N Other subsequently obtained a quotation for tooling at £700 + VAT and unit production cost £2.90 + VAT in quantities of 300-off. This is considered a viable means of sourcing the actuator but this quotation has not been re-validated since 2004. Neither is it known, in 2013, whether this supplier still exists and would still be interested in the project.

The original proposal was that A N Other would outsource the reconditioning process to a specialist locksmith who would dismantle, examine, rebuild, and test each lock. An exchange service would be operated through the established Stag suppliers, either on a ‘service exchange’ basis (includes two new keys), or on a ‘repair and return basis’ (retains original keys). In addition, A N Other would operate a repair service direct to members of the Stag Owners Club (e.g. via Ebay or other online shop).

SOCTFL is concerned with feasibility investigation into projects, provision of grants for tooling (e.g. for the actuator), and loans for stock (first-off production batch). It is not concerned with running projects directly. The commercial arrangements for delivery of the project would therefore be negotiated directly between A N Other and the Stag suppliers without involvement from SOCTFL. The choice of suppliers is at the discretion of A N Other but is likely to include the retailers that typically advertise in the magazine.

Based on the figures above it was anticipated that the unit cost charged by A N Other to the suppliers will be £50 (no VAT), and that the retail price will be circa £70 (plus VAT). Whilst these figures were based on 2004 prices it should be bourne in mind that (a) the value of the cars has not substantially increased since then, and (b) the continuing availability of some NOS and used parts will dilute the potential market. Therefore it may be that there is little room to increase these prices whilst stlll achieving a viable level of sales. It would be worth conducting an on-line poll on the Forum to find out what owners would be prepared to pay.

Mike, Phil,

Thanks for the feedback and update. At least the supply issue is back 'on the radar' again and hopefully there will be a solution before mine packs in...........

Keep up the good work. SOCTFL's efforts are appreciated by me, especially having spent my kid's inheritance on new panels for my Stag recently..............
