nang Posted December 10, 2017 Share Posted December 10, 2017 I'm sick of trying to get my o/d fixed over here. I know it won't be cheap but is there anywhere that I can get a good or recon J type overdrive from UK. Everyone seems to want an exchange unit, Fair enough, I can see why, but the cost of sending my old one over would make the whole exercise impossible.Triumph 2500.Thanks.Tony.

Nick Jones Posted December 10, 2017 Share Posted December 10, 2017 Tony,A man of your talents shouldn't have any major problems sorting it at home. They are not complex. Some tooling investment (gauges & adaptors) might be needed but small beer compared to shipping costs. Possibly you might still need to buy parts from the UK (relined clutches etc) but relatively small and light.A type or J type? Buckeye Triumphs have great write-ups on bothhttp://www.buckeyetriumphs.org/technical/technical.htmCheersNick Quote Link to comment Share on other sites More sharing options...
nang Posted December 11, 2017 Author Share Posted December 11, 2017 I'm going to have to go inside...It's not electrical as most of my previous prpbs have been.This afternoon I ran a live feed through a switch to the solenoid. Could hear the solenoid going click but nothing else happened on the road.I've had the 3 plugs under the sump out and replaced most things. An "expert" has already been through the gearbox and o/d. Gearbox is fine, just the bloody overdrive.Can I get it off the o/d off the 'box in place, and more importantly get it back? It's a J type.ThanksTony.

Pete Lewis Posted December 11, 2017 Share Posted December 11, 2017 ive found many operational problems are due to the solenoid internal shuttle is stuckunscrew the solenoid with a , 1" af thin spanner dont turn it by the body,remove and lookin the end there is a small 10mm circlip, pop this out and shake out the shuttle /spool valve inside this must be a easy slide/ loose rattles when shaken . if its stiff it wont work .a clean and maybe new 0 rings on the shuttle and the body .if you have a battery( these dont need mega amps ) you can fire the solenoid and see if the inside bit actually moves worth a quick look.Pete Quote Link to comment Share on other sites More sharing options...
nang Posted December 11, 2017 Author Share Posted December 11, 2017 Sorry, didn't mention I've been into the solenoid,replaced all the O rings ,even the inside ones, and even replaced it with no improvement. Tony. Quote Link to comment Share on other sites More sharing options...
Nick Jones Posted December 11, 2017 Share Posted December 11, 2017 I think you probably could get the OD off the box without removing the box from the car. You might even get it back on again (lining both sets of spline up is always a royal pain). However, you'd probably find the the rest of the gear box very handy for test purposes - you can spin the gearbox up with a decent electric drill (my 500W Bosch just managed it) to test the OD, measure pressures etc.Nick Quote Link to comment Share on other sites More sharing options...
nang Posted December 12, 2017 Author Share Posted December 12, 2017 Many thanks Nick, I'll keep the forum informed as to what I find......I've really got to fix this bloody thing (huh)Tony. Quote Link to comment Share on other sites More sharing options...
josh18 Posted December 13, 2017 Share Posted December 13, 2017 I took my OD off the box once and we found it very hard to get it to release. The book said to pump pressurized oil into somewhere to release it. We didn't have oil so we used compressed air. It worked in the end but it was pretty painful.

Pete Lewis Posted December 17, 2017 Share Posted December 17, 2017 wont be the first time ive found the rebuild left the pump cam keyway out , so no pump actionPete Quote Link to comment Share on other sites More sharing options...
Pete Lewis Posted January 10, 2018 Share Posted January 10, 2018 Just had the J type OD off my gearbox and it pop on /off easy there is a plug or nipple to pressurise the clutch pump but ive not needed toIts located next to the filter coverthe j type has a self aligning pump 'big end' so positioning the cam low is not needed if alignment on refit is blocked , just pry the two piston bars with a couple of screwdrivers and this opens the clutch just remove them when it drops on.pete Quote Link to comment Share on other sites More sharing options...
