kevine Posted May 16, 2017 Report Share Posted May 16, 2017 Good Morning Having removed the solenoid bracket on my A overdrive to replace the gasket and apply a sealiing compound, I wanted to see the condition of the spring and spacing tube. On removal a washer / spacer I believe fell out with it which I was not expecting. The size is 21 mm Dia with a 5mm hole flat on one side. On the other side it has a raised section 12mm dai and 3mm high. ( all measurements are approx) I assume this fit into the spacing tube. I believe the flat side fits against the spring whilst the raised piece will fit into place when inserted. My hesitation is that I cannot see clearly to see if this is correct. Any thoughts please as the brown book and moss do not show the relevant part. Thanks Kevin Quote Link to post Share on other sites

stuart Posted May 16, 2017 Report Share Posted May 16, 2017 Possibly a DIY solution to a worn spring to up the pressure. Stuart. Quote Link to post Share on other sites
kevine Posted May 16, 2017 Author Report Share Posted May 16, 2017 Thank you. I have spoken to Peter at ORS as suggested by Bruce. He seems to think it might well be a spacer of sorts. This also backs up Stuarts post. As the overdrive was working well before I think I will refit and see. Kevin Quote Link to post Share on other sites
kevine Posted May 16, 2017 Author Report Share Posted May 16, 2017 Just got home and looking at the Moss site. I now see a reference to part number 93 which appears to be a plain packing washer WM58, believe this could be what I have albeit differant. (packing washer) has anybody noticed this before in their overdrive sleeving tube? Thanks Kevin Quote Link to post Share on other sites
Litespud Posted May 26, 2017 Report Share Posted May 26, 2017 Washers are inserted into the tube to increase the oil pressure of the O/D system - could be the spring was old and tired. My A-type had a couple of washers in the tube when I overhauled it, so, in the interests of "leaving well enough alone", I put them back when I reassembled. My concern with your washer is that, from the sound of it, depending on the orientation, you'll get maybe 1mm of "spacing" (with the raised section sitting into the spring) or ~4mm, if the raised section faces away from the spring - the difference would likely affect the O/D pressure. In your situation, I would replace the spacer with the raised section inserted into the middle of the spring, reassemble sufficiently to run the system, take it out for a spin and see of the O/D engages in a timely manner (too low pressure will likely result in a significant lag in O/D engagement). If not, flip the spacer and retest. I went through this a while back. I reassembled the O/D, reinstalled the dash support (not the tranny cover) and took it out for a spin. Just watch out for that big old U-joint spinning right underneath your elbow! Quote Link to post Share on other sites
