Dibbo Posted June 23, 2017 Report Share Posted June 23, 2017 Hi, Ive asked in the wanted section for a replacement dipstick , as the center bit on mine has vanished ( inside the box I fear) does anyone have one they can measure the length of, as they seem hard to get so thought I could make a new one if I had finished length and distances for full and empty. Thanks Dibbo Link to comment Share on other sites More sharing options...

Thanks Dibbo If you have damage the dipstick and it has fallen inside I suggest you remove the box and have the piece removed. We had a piece missing off one of our gearboxes which eventualy found its way into the pump inside the box and shagged the box. Edited to add that ours was a prm 500 so I am unsure as to wether the same would apply to a small box. Edited June 23, 2017 by mrsmelly Link to comment Share on other sites More sharing options...

Ex Brummie Posted June 23, 2017 Report Share Posted June 23, 2017 I saw one retrieved by an RCR mechanic, using an extendable magnet, back through the filler hole. Link to comment Share on other sites More sharing options...
Sea Dog Posted June 24, 2017 Report Share Posted June 24, 2017 If your gonna replace your dipstick, I hope you do a better job than PRM - trying to judge the level of clean, clear oil level on my PRM150 shiny steel dipstick is a bloomin' nightmare! 1 Link to comment Share on other sites More sharing options...

mross Posted June 24, 2017 Report Share Posted June 24, 2017 (edited) My PRM 160 dipstick is 8 1/4" long. Low mark is at 1/2" and high at 1". Edited June 25, 2017 by mross Link to comment Share on other sites More sharing options...

I think the damned thing most have a special oil repellent coating, cos it leaves barely a mark and certainly not usually enough to be definitive. It is how I do it, but it seems to take an inordinate number of attempts before I'm sure the level is right. I'll bet I'm not alone in this view as the PRM150 is not an uncommon gearbox.

Mike Tee Posted June 25, 2017 Report Share Posted June 25, 2017 after wiping the dipstick dry, rub a piece of ordinary blackboard chalk on it, then re-dip and the level shows up clearly 1 Link to comment Share on other sites More sharing options...

Not only the 150, my prm 260 box dipstick is the same, can't see the oil on it either. Bazza Link to comment Share on other sites More sharing options...
cuthound Posted June 25, 2017 Report Share Posted June 25, 2017 I made up a dipstick out of a black cable tie, as it is easier to see the oil level against black plastic. Also gets round the fact that the correct level is with the dipstick unscrewed, not screwed in, which has been known to cause confusion on this forum.

mross Posted June 25, 2017 Report Share Posted June 25, 2017 One of the might work better than a magnet. The magnet will stick to the casing and some of the internals. www.google.co.uk/search?q=picker+upper&client=ms-android-wileyfox&prmd=sivn&source=lnms&tbm=isch&sa=X&ved=0ahUKEwjjn961_9jUAhVMB8AKHfBVAqUQ_AUICigC&biw=360&bih=512#tbm=isch&q=pickup+tool&imgrc=5jdKHYvHRtFgPM: Link to comment Share on other sites More sharing options...

Even the user manual states that the dipstick should be screwed down! See para 6.1 on page 18. http://www.prm-newage.com/media/uploads/5050834c6f7e0.pdf Edited June 25, 2017 by mross Link to comment Share on other sites More sharing options...

Yes, thinking about it the RCR engineer said if you don't screw it in the lower mark corresponds with the top mark, so don't screw it in and then fill to the lower mark.

RCR man told me to roll the dipstick gently on the back of my hand. When I did that it was much more obvious where the level was than when I did it on a bit of bog roll.

Dibbo Posted June 27, 2017 Author Report Share Posted June 27, 2017 Thanks for help and hints, tho it did go a little off topic! Lol... Will make a new dipstick myself as I'm not spending 30 quid and both sites selling them say they're out of stock.... Still fishing for old one tho.

See my later post, where I remembered that the RCR engineer told me that the level should be checked with the dipstick screwed in, but the difference between the high and low marks is the same as the length of the thread. So unscrew the dipstick and fill to the lower mark to get the correct level. Link to comment Share on other sites More sharing options...

If you can see oil,but there obviously isn't too much, all is well! Link to comment Share on other sites More sharing options...
