Talk Morgan Forums Morgan Sports Cars Classic Morgans (pre-CX) Rear springs

I suspect that was the same dealer who messed me around Colin.

I had noticed that Peter (aka PJB) was reluctant to make posts on the forum on some issues as he was worried about this being seen as a conflict of interest or promoting the products of a company that he is associated with.

Sometimes there may be a fine line between what is seen as helpful advice and what is seen as promotion. My personal attitude is that comments should/can be made with the proviso that the interests of the author are clearly declared, does not denegrate the products of another company or person, offers advice of a general nature within the competence of the author but with the exception of answering specific questions relating to the authors products.

My view is that Peter (and others in a similar situation) has always been very careful to comply with these 'unwritten' provisions in that they fall within his own code of ethics.

Personally I always find Peter's posts interesting and informative and, whilst I understand his reserve, I don't think he has crossed the line. Obviously I can't speak for Simon and/or the mods but I don't believe that Peter's posts could be construed as covert advertising or full of' outward links'.

Peter,
I would agree

We are so fortunate to have the real trade experts intervening with positive contributions on TM and in 11 years on here have never noticed any one of them pushing a product for gain.
It’s always about supporting the Morgan community it strikes me and long may it be so🚗😃

I am no real expert on anything, though I seem to remember aspects of this conversation first appearing on eMog many years ago and if my dull memory serves, in one discussion it was determined that a brand of adjustable shocker/damper (Spax ?) found it`s self forced to act as a bump stop even once, its adjustable function would no longer operate..?

It seems that it may not be unusual for Trad Morgan suspension travel to come to a jarring halt and that on occasion may be the result of sagging springs and if that may be the case then replacement springs would seem to be required to restore lost suspension travel..?

I suspect fitting spring assisters may provide a work around of sorts if suspension travel reduction has created a more regular jarring ride, and as ever it seems Morganeers may be inclined to have their own ideas on modifications to resolve the issue that seems may affect a few Morgans..

If even with correct spec springs shockers of shorter than correctly specified fully compressed length are fitted, and as such are forced to act as bump stops this may create unintended issues and thus caused me to ask the questions repeated below.

Should there be any misunderstanding of the description of my use of the word "jarring," then if you care to beam up the vid below and jump in at circa 7:20 you may find an example... Who was it said an image is worth a thousand words..? Now whether just for effect in the making of the vid they had driven around to find a particularly deep pot hole, and had practised some acting skills to give the impression of shock immediately after encountering the road imperfection... I know not, but it definitely came across as a not fun event..?

The idea that a shocker fitted to a Trad might also act as a bump stop seems far less than ideal. I can understand that there may have been quality issues relative to leaf springs ageing "prematurely" and thus exacerbating the already minimal suspension travel in a Trad, perhaps even more so in Trads with tubular shockers than the original design concept that utilised lever arms..? If the aforementioned might be the case, that would cause me to wonder if lever arms ever suffered the similar situation of them becoming involuntary bump stops...?

I understand that many tubular damper suspension designs have bump stops built in. Trying not to come across as pedantic, I was enquiring if any tubular shocker fitted by MMC in a Trad was designed to also perform as a bump stop..?

My question can be taken a stage further to ask if any shocker manufacturer (AVO ?) has intended their shocker design to be used in a Trad Morgan to also perform a bump stop function...?

It is Konis that lock up on the first bottoming out.
GoMog on shocks

I always found it very helpful to hear the recommendations and advice of the experts here. I have the impression that they are trying to avoid self-praise and the forced promotion of their products and services as much as they can. Also, most members of TM always emphasize that they are not related to an expert or benefit from it if they are very satisfied with something. Maybe it was me who was so enthusiastic when describing the new shock absorbers in this thread because I was so lucky with the random fitting length and I forgot to make the announcement not to be involved with the supplier, and they are really good. Again, you can ask any supplier if they can offer such a product.

We are grown up people who see who says something and why. And as it runs on TM, I always found it an enrichment when experts who are also commercially positioned have their say. For example, when someone designs springs and suspensions, it is logical that he describes what he does and how it works. If it is connected with very useful tips, why not.

Do you mean like this? I think MMC fitted these Bilsteins to the 4 seaters

John, thanks for the GoMoG link, it is an amazing resource. At least I remembered that there was a brand of shocker where the adjustment was damaged by it acting as an involuntary bump stop..even if I did not identify the correct brand...Duh..!

Thanks for posting the pic Roger. Given the amount of and shape of the rubber moulding on the shocker shaft, it seems to have potential to resist the internals of the shocker bottoming out and being damaged..

Could be relating to the angle the pic was taken at but it seems there may not be much "free"movement of the shocker before the rubber begins to compress.. interesting design, I wonder if once the car is fully assembled that the extra weight compresses the shocker shaft to the extent that no bare chrome is left exposed, and thus rubber also acts as a dust cover, and at some stage of compression becomes a bump stop..?

Seems all too simple to fit an unsuitable shocker in terms of it either being too short at max extension which may be less of a problem than being too long on max compression, thus risking internal damage..?

I had a new 4 seat in 2008 with this very same damper arrangement. There were mega issues with soft rear springs and part of the discussion with the dealer/MMC on the total lack of clearance between this rubber device and the damper body. I was assured by MMC and it was later confirmed by Peter Ballard that these in fact are not bump stops they are spring assisters and it was completely normal for the vehicle to run with them in contact on measurement the total rear axle movement in bump of about 20-25mm, crazy!

We were at the point of me rejecting the car as unroadworthy when the MMC finally agreed to the dealer sourcing a pair of rear springs from Mulfab (I collected and delivered them) and a pair of Spax rear dampers to be fitted.

The car was at the dealer for 4 months to sort this out as I refused to accept it, one set of rear springs supplied by MMC were so soft the car sat (when empty of fuel, no luggage or occupants) on full compression!
