LM100 Gearbox

[Riverway]

G/Day.

 

Im in the process of overhauling my LM100 G/Box

 

Im wandering if anyone can throw a bit of light onto what the orginal thickness of the linnings on the cone drive and the reverse brake band would be?

 

Cheers Alan

I owned the company that lined gearbox bands and cones for Listers and relined the same for several of the larger parts suppliers. You should remember that both bands and cones run "wet" that is to say in oil and therefore any material you use MUST be a specialised "in oil" friction material. Normal woven material will not work, in fact may degrade and gum up your box completely.

 

The material on the cones is a special woven material, nominally 3.2mm thick, but is ground after bonding (thermal setting) to a cone template. The material on the band is a paper material, imported from the US, and was 1mm thick.

 

I do not want to sound too down, but this is not a job for the amateur. If you have problems contact me and I can point you in the right direction.

I don't think the OP was considering relining them himself!

 

It sounded to me as if he was trying to determine whether the linings were sufficiently worn to require replacement.

and Priston answered the question very well but also, as he appears to have experience, suggested it was not suitable as a job for an amateur.

 

Riverway has a bigger problem though it is all upside down.

Thanks very much for your reply, My plan was to send the cone etc to a brake relinning company north of me who do the bonding process, by the sizes you have stated the band is ok, but cone linning I beleive has given up from old age and falling apart...

 

I have spoken with them about the linning composition and said it was a wet clutch with a woven brass included, all appears ok there

 

The relinning company has requested the clutch housing where they may use it as a guide to set the linning in place on the cone while in the bonding process . Does this sound correct.

Alan,

 

Yes this is a recognised method for a "one off bonding" approach. The clearances on the cone are quite tight and therefore setting the male and female is critical. I assume yours is a mechanical box, ie the shift is by mechanical linkage, this is the easiest since if the cone is tight an extra pressure on the shift is easily applied. On the later hydraulic shift boxes this extra pressure was not availble, hence the need to final grind the friction material to a predetermined size it situ.

Once again thankyou for your information, your correct in that it is a mechanical box, the issues Im having is that no local company will bond cone clutches, they said they had to many failures , one of my options was to buy a new cone clutch until I was quoted $Aus700 , so after hearing that it was back to the bonding,Hopefuly the company Im talking with now can do it and they dont have to send it 2000km south to another company. So you can see my concerns on sending to many parts away if any get lost or damaged $$$

I must say I have rebuilt quite a few different engines and gearboxes over the years and after pulling this box down Im pleasantly supprized with its condition,its quite a robust little box.

Will see what happens next

How much????

 

That's 300 quid!!!

 

I've replaced a cone clutch in an LH150 (I believe the part is identical), and it sure as hell didn't cost that much. (IIRC, it was about 70 quid)

If you are interested a NEW GENUINE Lister Petter cone is £221.61 rsp..however we can offer relined cones @ £85.00

obviously there would be carriage charges but still could work out a lot cheaper

Our relines are ground to the stated Lister dimensions so we know they are correct for the job

Thanks for the prices guys they certainly are worth considering, first I will see what the reliners here say when they get the parts, also there quote,

At 85 pound thats $A200 plus air freight

" 221.61 pound is $A522.82

That would be landed in Australia and yes some nice lunch money there

Hi Chris

 

I sent a email to your day link re cone clutch can confirm it was received?

 

Cheers Alan
