Suspension data

#1 Post by torque2me » Sat May 03, 2025 2:52 pm

Hi,

Can anyone provide tracking data for a T2500s such as toe in/out? Pointers to publications is o.k. but much of my Triumph manuals and documentation is in storage at the moment.

According to two official BL workshop manuals (AKM 3974 and AKM 3647/A) the figures differ.
AKM 3647/A - MK1 and MK2
front - 1/16th to 1/8th" toe in (1.58mm to 3.18mm)
rear - 0 to 1/16th" toe in (0mm - 1.58mm)
AKM 3974 - Mk1 and Mk2
front and rear 0 to 1/16th" (0mm to 1.6mm) toe in
laden
AKM 3974 is the later print of the two and refers to the 2500S in its data.

But as discussed earlier today in another topic, this data is presumably assuming there is no wear in any suspension components. But who has a non wearing suspension system? :wink:

Thanks for that reply johnnydog, most helpful in that I'll provide that to the "bod" doing the tracking. I'm going to guess there will be a shrug of the shoulders and they'll just do their own thing!

hello Both,

just an aside,

modern equipment seems to work in degrees, so some conversion required?

Just another point too - any adjustment of the rear track involves the addition / removal of shims between the swinging arm shackles to the box sections - which I very much doubt they'll have 'in stock'. It's more than a 5 minute job as well to add or remove them so I doubt they will be keen to do that aspect of adjustment. It may be worth getting the rears checked initially, and if some adjustment is required, ordering the shims and then going back to them. Get the rear tracking correct, (especially if the rear end has previously been dismantled) before tackling the fronts (which is the correct way to do it).

A very good point Alec. You don't happen to know the conversion formula do you?
