Duffy Posted April 4, 2014 Share Posted April 4, 2014 I understand the track is different. The Stormer drive sprocket teeth are notably larger and the horn on the Stormer track is again notably longer. My question: Is it safe to run the Stormer track on my Spartan?

timbo Posted April 4, 2014 Share Posted April 4, 2014 Al As you rightly point out Stormer track is of a different design to original CVRT track. Whilst I imagine it could be made to work somehow, I have been told by people who know about these things that it is strongly inadvisable ie it is best to leave it as nature (ie Alvis!) intended... Cooks (who make most of the track) now advertise 'bigfoot' track (ie with thicker pads) and a version of the original track with a replaceable pad. I have always been a little dubious about replaceable pads on CVRT, due to the high road speeds but the thicker pads would be interesting to try. In 8 years of owning CVRTs Ive never actually been forced to replace a set of track, only now starting to think about it, and even then I can probably squeeze another two seasons out of it at a push (worn pads not bushes).

Cornishbloke Posted April 4, 2014 Share Posted April 4, 2014 Some CVRT were modified to work with long horn chevron track. The most noticeable alteration is a box cut out of the sponson immediately over the drive sockets to allow for the thicker pads. I don't know whether the sprockets or the carriers are modified and whether the rear idler has to be changed to allow for the longer horns.

BRDM Driver Posted April 4, 2014 Share Posted April 4, 2014 While talking CVRT track, is it worth hanging on to old CVRT track (worn pads, but good bushes)? I have two sets taking up space, but if a reconditioning process becomes available, I'd be kicking myself for taking it all to the scrappy...

robin craig Posted April 5, 2014 Share Posted April 5, 2014 Well, pull up a pew and lets have a chat. The basic CVRT powered by the J60 and the Stormer powered by the Perkins are what we have at work. I think I am one of the few people who has access to both side by side. Today at work I took a few minutes to try and answer the questions thrown out by Mr Duffy The first picture shows a section of "new" Stormer track, the one with the chevron pattern (that you can't see) laid beside a Spartan which has barely used track. So, observations, the two of them appear to have links that are the same length overall, but we know that is not what we were asked. I struggled to find a measuring tool with horns long enough to get down into the contact points in the tracks In the end we have an approximation until I get a better measuring tool. What is clear is that the CVRT has a shorter slot for the drive sprocket than the Stormer, it is only a few millimeters but it is obvious when side by side. My determination is that Stormer track will turn on a CVRT drive sprocket, but a CVRT track would bind up on the sprockets of a Stormer. As far as total height of the links the Stormer track is much thicker and has a parallel rubber surface whereas the CVRT track has a rubber surface that has an angle to it. I would suspect that anything more than shunting around the yard and the thicker Stormer track would bind under a sponson somewhere. You could likely cheat a bit by using Stormer drive sprockets on a CVRT hub with Stormer track (I think they are the same but will have to check) but the overall height of the links would still be the concern. I hope this helps those concerned. I will try some better measurements of the coming days. Robin Quote Link to comment Share on other sites More sharing options...
robin craig Posted April 5, 2014 Share Posted April 5, 2014 I just wanted to clear up a detail that I asserted in my previous post that was wrong. the Stormer track does has an angle to the rubber pads, as shown in his image. Apologies for my mistake R Quote Link to comment Share on other sites More sharing options...
robin craig Posted April 6, 2014 Share Posted April 6, 2014 It has gone very quiet on this subject. No one else want to add anything? I was kind of waiting for a couple of people to add a few things R Quote Link to comment Share on other sites More sharing options...
Grasshopper Posted April 7, 2014 Share Posted April 7, 2014 My understanding (from a conversation with A.B long ago) is that prolonged use of Stormer track on a CVRT will cause the rear idler to crack due to the difference with the horn depth. Stormer rear idlers are different to CVRT, as are the final drives (I believe that CVRT were upgraded with Stormer final drives as part of the deiselisation process). I do believe that Stormer front sprockets are also different. Quote Link to comment Share on other sites More sharing options...
sirhc Posted April 7, 2014 Share Posted April 7, 2014 The Stormer final drives are different, but are not fitted to the diesels as standard.. They are part of the 235 upgrade. The sprocket rings and carriers are different. Quote Link to comment Share on other sites More sharing options...
m109a3uk Posted April 8, 2014 Share Posted April 8, 2014 Looks like that track has jumped and wedged itself against the hull!! Quote Link to comment Share on other sites More sharing options...
