Sprint engine mounts.
Recently fitted new pattern mounts to my Sprint engine, I noticed a week or so later the gap between the oil pump and rack was about 8mm, now a few weeks on its almost touching.
So, the mounts I have fitted are rubbish - no prizes for guessing where they came from!
I still have two sets of original mounts which are delaminating, has anyone ever found a company that car effectively re-rubber the originals....if there is such a possibility.

Re: Sprint engine mounts.
I don't believe so, but it is something we need to investigate...

Re: Sprint engine mounts.
Problems with the current supply of engine mounts is concerning as there is no alternative supply. I will in the not too distant future have to look at fitting mounts to my car. The original mounts are in poor condition and I'm loathed to fit poor quality 'new' ones. I did make enquiries with Bonaprene (Polybush) last year as we had some Jaguar engine mounts made for work. Whilst they could easily either make new mounts with an appropriate grade of polyurethane or refurbish bare plates the minimum order was prohibitive. I think there may be some mileage in exploring this further, perhaps with an alternative supplier. I was attracted to Bonaprene though because they do make very good poly engine mounts for other cars and have successfully boned the poly to the metal whilst retaining the degree of shear required in the material i.e. it's not too harsh.

Okay........
What was the minimum order?SprintMWU773V wrote: ↑Thu Sep 28, 2017 9:06 amI did make enquiries with Bonaprene (Polybush) last year as we had some Jaguar engine mounts made for work.

Re: Sprint engine mounts.
Ideally no fewer than 150 and are they not different on each side? I forget.
There are possible other sources. The secret will be getting the right grade of material, so if anyone has any ideas on the material grade then do feel free to share. The real issue seems to be sinkage and delamination with these repro parts, when they work they seem to work OK, they just don't last.
I have seen that there's a company making poly mounts for an MK1 MX5. These probably wouldn't be a suitable direct replacement but they do work in a very similar way to the Dolomite ones, though they only have one mounting bolt on. The basic design may be adaptable to the Dolomite with some engineering.

Re: Sprint engine mounts.
They are the same both sides.
I would have thought 75 pair would be viable...why not get a quotation and approach the committee?

Re: Sprint engine mounts.
This is the issue I have with saggy mounts!!!!
Sometimes I feel like giving up with this car
Saggy engine mounts
Lowered coil springs that seem to sit higher than standard
A new engine stabiliser that's shorter than the old
A new battery negative lead ordered for a Sprint a good two inches too short
A set of core plugs that wouldn't go in
The list goes on.

Re: Sprint engine mounts.
It is not only sprint owners that have a problem finding engine mounts so if possible please consider the other models in the dolomite range.
Yes.......
On the former I concur and about the latter I have sent you a PM Alun.

Re: Sprint engine mounts.
I was thinking of getting in touch with AV Industrial Products for when the time came to change mine, but I'd obviously be interested in a set of club ones instead.
Current fleet: '75 Sprint, '73 1850, Daihatsu Fourtrak, Honda CG125, Yamaha Fazer 600, Shetland 570 (yes it's a boat!)
Past fleet: Triumph 2000, Lancia Beta Coupe, BL Mini Clubman, Austin Metro, Vauxhall Cavalier MK1 & MK2, Renault 18 D, Rover 216 GSI, Honda Accord (most expensive car purchase, hated, made out of magnetic metal as only car I've ever been crashed into...4 times), BMW 318, Golf GTi MK3 16v x 3

Re: Sprint engine mounts.
As I first started looking at this last year I've volunteered to have another look.
It's been a slow day at work today so things have progressed quickly. I've had good discussions with two manufacturers and I've agreed to send samples out to them. Both sound very positive and I'm pleased to report they do seem adopt an engineering approach to the project. I'll hopefully be looking for a volunteer to assist with part of the research early next week. The discussions I'm currently having are based around Sprint mounts but if things look favourable I will also look at mounts for the other cars in due course.
I'll also have a look at good quality rubber, the basic problem seems to be the quality of the rubber used and the ability to bond it to the backing plate. At work we have produced some not entirely different mounts so have come across AV Industrial before.
I'll shortly start another thread on the mounts project and I welcome your comments and thoughts there or via PM.
