phil Dean Posted March 26 Report Share Posted March 26 Yep I know and I have seen it mentioned before but had a look and cannot find it. I have used Muc Off in the past it makes a good job of cleaning a very muddy bike and chain but know I have the diff out squeaky bum time, somebody had been there before the nuts on the prop were all rounded off managed to get 2 off with spanners and 2 with mole grips and spanners but it was a close thing and they were so so tight. How ever after cleaning the diff with muff off only did half a job do people still use Gunk or is there something far superior . I intend to drop the sump hopefully next week clean and straighten it if required, and suspect what ever is left in the sump after draining will take something better than Muff OFF to get clean.

RogerH Posted March 26 Report Share Posted March 26 Hi Phil, I use Wynn's Brake & Clutch cleaner. It works very well on any grease / oil I prefer the aerosols for convenience but not cheap. A 5ltr can is significantly cheaper but less convenient. https://www.ebay.co.uk/sch/i.html?_from=R40&_trksid=p2334524.m570.l1313&_nkw=Wynnes+Brake+%26+Clutch+cleaner&_sacat=0&_odkw=Brake+%26+Clutch+cleaner&_osacat=0 Roger Quote Link to post Share on other sites
phil Dean Posted March 26 Author Report Share Posted March 26 Thanks Roger I have some of that I just wondered if there was something to get rid of the real gunky stuff in the bottom of the sump. Phil. Quote Link to post Share on other sites
RogerH Posted March 26 Report Share Posted March 26 Hi Phil, Soak it in White Spirit and use a scrapper to loosen. Once removed, the inside of the sump can be cleaned with the cleaner of your choice. Roger Quote Link to post Share on other sites
Lebro Posted March 26 Report Share Posted March 26 I use "Hyperclean" it is a water soluble degreaser. I apply with either brush, or spray gun. https://www.ebay.co.uk/itm/334919158316 The last lot I bought was in a 40 litre drum, (it was on offer) should last me out.

rcreweread Posted March 26 Report Share Posted March 26 Phil - I always use petrol but be careful not to cause a spark and use a stiff brush/old toothbrush/small flat bladed scraper to shift the really hard crusted stuff, a lot of which is often around the diff. Once cleaned off of oil, I then go over the steel bits with an angle grinder with cup brush to get all the rust off and provide a nice base for a coat of paint. If the Coxes are rebuilding your diff, get them to put a drain plug in the bottom of the casing - if you want it to look the dos do-dahs, get then to powder coat the front and rear mountings to get it looking like the one in the photos below Cheers Rich Quote Link to post Share on other sites
trchris Posted March 26 Report Share Posted March 26 Hi Phil l use a product called elbow grease any supermarket has it about£2 ish for a trigger spray works wonders even on the bbq Chris Quote Link to post Share on other sites
Steven Whitaker Posted March 27 Report Share Posted March 27 I can say having bought 10 litres of Gunk, that it is not much better than soapy water since they EU'd it..... Quote Link to post Share on other sites
Lebro Posted March 27 Report Share Posted March 27 Agree, current Gunk is useless. Hyperclean really does work. Bob Quote Link to post Share on other sites

rcreweread Posted March 27 Report Share Posted March 27 Mick - the black paint on the main body is Lidl metal protection gloss black - I do however go over the main casing with twist knot wire wheel in a angle grinder to remove all rust and scale - you can then read the serial numbers which are often too faint to read under years of crud and rust The front mounting bracket is powder coated black and the rear one powder coated silver Cheers Rich Quote Link to post Share on other sites

phil Dean Posted March 28 Author Report Share Posted March 28 (edited) thats ok Rich today I am going to try and make a wooden buck that the diff can sit in when I lift it back into the car hopefully make it more stable can also use it for transporting it down to Peter Cox sports cars next week.
