silverfox4 Posted February 7, 2018 Report Share Posted February 7, 2018 Not sure that this warrants it's own topic, but the hassles endured with removing a one-piece Poly cover installed by PO (with good intentions), and the cross-threaded 1/4-24 nuts, out-of-position seals, missing bolts really was cause for a re-think here. Found a local source for a nice looking bit of kit at fair price. Apart from other supposed advantages, even it helps to install a cover properly, that will be a bonus for me and my back...

Motorsport Mickey Posted February 7, 2018 Report Share Posted February 7, 2018 Yeah we have a similar offering here, it started out very much like the tunnel shown in the photos but it's had a few "hatches" and cut outs designed into it to make life even easier. http://www.racetorations.co.uk/triumph-c56/tr4-c6/tr4-interior-and-trim-c41/racetorations-split-gearbox-tunnel-tr4-p199 Mick Richards Quote Link to post Share on other sites
silverfox4 Posted February 8, 2018 Author Report Share Posted February 8, 2018 Thanks for link Mick. I see Racetorations have both Poly and Fiberglas variations with multitude of cut-outs - nice, but probably double the price. This one is from Clark & Clark. They do have an optional cover for the speedo drive. The Solenoid, oil fill and OD switches... well I guess buyer has give it a go... Cheers, Alf Quote Link to post Share on other sites
ianc Posted February 8, 2018 Report Share Posted February 8, 2018 I fitted a Racetorations 2-part cover in 2004, before Darryl incorporated some of the improvements shown in the current catalogue. Mine is fibreglass and fitted well as I took a great deal of trouble to get each mounting bolt hole in the correct place, drilling as many as possible from below with the cover braced into position as required. I cut the side hole for gearbox filler (TR4) and an access to the overdrive solenoid. Ian Cornish Quote Link to post Share on other sites
signalredshaker Posted February 8, 2018 Report Share Posted February 8, 2018 Just to say I have just fitted one of these from Racetorations. Pricey, but a great fit. Somewhat thin in a few places and almost see through in one or two. No detriment as I have covered the lot with 3mm Silent-Coat in the hope this will stop the noise a bit. Mine came without rubber bungs for the three holes that were pre-cut (propshaft, O/D operating shaft and gearbox filler) but they soon followed at no cost. All looks good so far but yet to try removal of either part. James Quote Link to post Share on other sites

rcreweread Posted February 8, 2018 Report Share Posted February 8, 2018 Don't you feel such a twit when you forget an attachment! I've got one of those yellow lights as well and the cable/gland came apart just like yours - easy fix if you take it apart ( disconnect from mains first!), and screw t all back together tightly Maybe thats why they were cheap! Like your gearbox cover very much but be careful if you are fitting underfelt under the carpet as well as your silent coat as it may get a bit tight fitting your H frame I wrote a book on here some time ago on how to achieve the same result for a lower cost with a cheapo g/box cover and get it to fit properly - don't know how to post a link to it, and it might also bore everyone to death so chickened out!

rcreweread Posted February 8, 2018 Report Share Posted February 8, 2018 Ok guys - the problem is I dont know how to extract and then post a link to my post - the heading of the thread which I posted in is: Gearbox cover, which is best? dated 08 May 2017 - 05:16 PM Not sure if this works or helps but if you can find the thread, my post is towards the end after which everyone went to sleep - yawn!!! http://www.tr-register.co.uk/forums/index.php?/topic/61963-gearbox-cover-which-is-best/?hl=%2Bgearbox+%2Btunnel&do=findComment&comment=528344 Maybe someone with more IT skills than me can post a direct link Cheers Rich Quote Link to post Share on other sites
Ade-TR4 Posted February 8, 2018 Report Share Posted February 8, 2018 All ears Mick! Especially as the two piece ones don't really fit that well...! (I have one and it's an "interference fit", as in, you have to interfere with it until it fits....) I'll get mi coat Ade Quote Link to post Share on other sites
silverfox4 Posted February 8, 2018 Author Report Share Posted February 8, 2018 Looking at some of the above posts, I still have to figure where the wiring for the OD switches and solenoid will penetrate the cover. I assume it will be the hole at front top right. Also, from Ian's comment, I had better take it slow to avoid further thread damage and leakage issues. I might even have a go without the gearbox in position. Cheers, Alf Quote Link to post Share on other sites

ianc Posted February 9, 2018 Report Share Posted February 9, 2018 With the cover jammed in position, I was able to drill pilot holes from beneath the car in a number of places, then open each of these holes to accept the bolt. This enabled me to clamp the cover using some of the bolts. The tricky part is determining the position of the remaining holes where one cannot drill from below, but some strips of masking tape on the floor can indicate the position of the holes, and these can be copied onto the cover, then a small pilot drilled and a file used to get the position right. Laborious, but worth the effort to get it right. It would have been easier with an assistant to hold the cover in position up top, whilst I worked from below, but I didn't feel it fair to inflict that on my wife! Unless Racetorations have done it already, one has to drill the hole for the overdrive cabling. Ian Cornish Quote Link to post Share on other sites
silverfox4 Posted February 9, 2018 Author Report Share Posted February 9, 2018 Great thanks Stuart, that will save time... Ian, this cover has all the bolt-holes already done, but, are they all in the right place, is what I still have to find out. The Racetorations version has a large removable cover at front centre top for the OD switch access I assume - is this feature considered worthwhile? Alf Quote Link to post Share on other sites
TR4A1965 Posted February 10, 2018 Report Share Posted February 10, 2018 I Fitted the Racetorations 2 piece cover. What makes it brilliant is the access cover to the speedo angle drive. If you have ever had the drive fail and have to get to it or replace a speedo cable you'll know what a major job it is. The Racetorations tunnel takes all the agro away - it is brilliant!!!! You can see mine fitted here: http://tr4a.weebly.com/triumph-tr4a-gearbox-tunnel.html Best Paul. Quote Link to post Share on other sites
ianc Posted February 10, 2018 Report Share Posted February 10, 2018 Alf - given that many TRs (including mine) have been re-built, it will be interesting to hear whether the bolt holes now pre-drilled by Racetorations fit the floor and bulkhead on your car! Please let us know. Ian Cornish Quote Link to post Share on other sites

Alf O/D switch access can be good if you have used repro switches as some of them arent that clever and have been known to fail after a short period of time. Stuart.

silverfox4 Posted February 10, 2018 Author Report Share Posted February 10, 2018 HI Ian, Sorry if I misled, but My 2-Pce cover is actually from Clark & Clark in Michigan (www.ClarkAndClarkInc.com)and the bolt holes are pre-drilled. I compared it to the Racetorations version for similar features, and the only ones this cover does not have is, the top access for OD switches, oil fill and solenoid access (and maybe the OD "drill setting" access) - I need to assess, but I hope these will be straight forward to accomplish. Stuart, thanks I will make that cutout for the switches. Alf Quote Link to post Share on other sites
TR4A1965 Posted February 11, 2018 Report Share Posted February 11, 2018 Oil change on gearbox today and I drilled a hole in the gearbox cover to take a tube to gravity feed the box with oil. Worth putting in this extra access - worked a treat! Quote Link to post Share on other sites
silverfox4 Posted February 11, 2018 Author Report Share Posted February 11, 2018 Pretty compelling pictures.Just need to establish exact location with appropriate access hole and rubber cover sizes - all in the fullness of time I guess. one off-topic sidebar question in first pic if I may - how do you get self canceling turn signals to work with Moto-Lita boss? Alf Quote Link to post Share on other sites
Chilliman Posted February 11, 2018 Report Share Posted February 11, 2018 Alf, a Moto-Lita boss has no bearing on the self cancelling mechanism for the indicators, that is all determined by a spring cam fitted below the boss on the steering column Quote Link to post Share on other sites
silverfox4 Posted February 11, 2018 Author Report Share Posted February 11, 2018 Thanks John, did not want to hi-jack, but I do have a new Moto-Lita wheel and Boss sitting on the shelf for over a year now and yet to be fitted - I keep seeing references or hints about fitting this set-up and losing self canceling signals etc, and I never see it addressed in any forum discussion, so, I snuck in a side one here. my apologies Alf Quote Link to post Share on other sites
silverfox4 Posted February 12, 2018 Author Report Share Posted February 12, 2018 With Stuarts input I have to use the hole at top right for the OD wiring and Speedo cable to exit. Can any one advise how stock my existing wiring and configuration are before I start directing towards that hole. The gearbox/OD can now come out for refresh and I can clean up and re-tap holes etc. I am now thinking that to fit the front part of the cover as final, on the assumption I can install the motor/ gearbox unit without being impeded by the front part of the cover - this could test all proposed openings? Oh yes, and are these driveshaft bolts the correct ones? Cheers, Alf Quote Link to post Share on other sites
