DC_ Posted July 23, 2016 Share Posted July 23, 2016 Posting this as we're working. Doing the timing belt and the water pump on a 1987 ex army 110 2.5 n/a. Weird this is there was no crank bolt to hold on the pulley!! Now we have the puller set on the pulley but it just won't budge. The puller is "just" wide enough to work and granted a bigger set would be ideal. Any thoughts on what else to do? DC Quote Link to comment Share on other sites More sharing options...
Leaky40 Posted July 23, 2016 Share Posted July 23, 2016 There are so many things to try but most may cause other damage!!!!! I.e the persuader!!! , pry bars being carefull not to damage anything else, big thick cold chisel gently tapping round between the engine and the pulley being carefull not to damage crankshaft, heat being carefull not to warp anything or melt anything including seals, copious amounts of penetrating oil/wd40 in case it's rusted in place. Is it held by a woodruff key type thing maybe? A bigger puller as you suggested. Not worked on this particular engine but seems strange not to have a bolt but it is a Land Rover!!!! These are just a couple of suggestions off the top of my head. Quote Link to comment Share on other sites More sharing options...
Leaky40 Posted July 23, 2016 Share Posted July 23, 2016 Just thought, if there was no bolt has it been welded on or something silly??? A puller really should do it!!!!! Quote Link to comment Share on other sites More sharing options...
DC_ Posted July 23, 2016 Author Share Posted July 23, 2016 No signs of welding as we suspected this too. Don't want to try the other persuading methods, over night soak in the WD and try again tomorrow maybe? Quote Link to comment Share on other sites More sharing options...
steve b Posted July 23, 2016 Share Posted July 23, 2016 ....you are pulling on the centre hub and not the vee belt pulley ? as it is rubber bonded to the hub . The bolt missing is a strange one , have you looked at the end of the crank for evidence of any sort of glue or damage ? cheers Steveb edit , it's probably the case that the bolt came loose and fell out then , really unusual for the pulley to stay on , as you say a good soak and try again , there is no chance of shifting it with levers all that will happen is damage to pulleys/rubber isolator/ timing belt cover Quote Link to comment Share on other sites More sharing options...
DC_ Posted July 23, 2016 Author Share Posted July 23, 2016 Yep pulling on centre hub. No sign of any botch job elsewhere. Hmmmm weird. Might just need s bigger pulley set. It's stuck on for sure Quote Link to comment Share on other sites More sharing options...
steve b Posted July 23, 2016 Share Posted July 23, 2016 You could try heating the end of the crank with a plumbers blow torch then rapid cooling with water , but there is a risk to the rubber bond . Sometimes a hefty wack with your biggest hammer to the puller centre bolt ( assuming not an hydraulic puller) when it's as tight as you can get it will break the joint , if the bolt has been missing for sometime there will be rust in the joint . let us know how it goes Steveb 1 Quote Link to comment Share on other sites More sharing options...
DC_ Posted July 23, 2016 Author Share Posted July 23, 2016 Still trying.... Poor signal too Quote Link to comment Share on other sites More sharing options...
Paddy Posted July 23, 2016 Share Posted July 23, 2016 Could also try a different releasing fluid, having worked in a refinery I know the effectiveness of "Penol" to release heat seized and/or rusted items. 1 Quote Link to comment Share on other sites More sharing options...
bodumatau Posted July 23, 2016 Share Posted July 23, 2016 we often used brake fluid as a release liquid, not sure how healthy it is for the seals and rubber etc.... but it seems to have worked. sometimes also helps giving it a smack in the OPPOSITE direction to that you want to pull it off.....might move a millimetre and then loosen and allow to pull it back and off.

DC_ Posted July 23, 2016 Author Share Posted July 23, 2016 Back home with cold one in hand and thinking...... If I can get my hands on a heavy duty puller set (large set) it might just be enough, don't know how I can smack it in the opposite direction though? Is Penol readily available in motor factor stores? I don't think i'll risk the brake fluid as it's very corrosive right? It's got my puller set on it just now as tight as we dare, it's got a mixture of WD and Acetone and ATF. (Don't ask) so I'm hoping the overnight soak and energy might work. Thanks guys for the advice so far, greatly appreciated as usual. Quote Link to comment Share on other sites More sharing options...
Tanuki Posted July 23, 2016 Share Posted July 23, 2016 I had this issue a couple of decades ago with the crank-pulley on a Ford Escort RS2000. After pissing-about for a fruitless and sweaty August afternoon with releasing-fluids and pullers and oxy-acetylene I bit the bullet and reached for the angel-grinder. 5 minutes later the old pulley was off. Often it's cheaper to murder old parts for a quick removal and fit new rather than waste hours futilely trying to get stuck bits off in one piece.

DC_ Posted July 23, 2016 Author Share Posted July 23, 2016 Did you see what the problem was? Rusted on? Quote Link to comment Share on other sites More sharing options...
vulcan bomber Posted July 23, 2016 Share Posted July 23, 2016 What you need is a proper puller that pulls from the tapped holes that hold the pully on. 1 Quote Link to comment Share on other sites More sharing options...
pat_pending Posted July 23, 2016 Share Posted July 23, 2016 If it's stuck on with Loctite or similar you'll be wasting your time with penetrating fluids. Heat is what it needs, and plenty of it! Quote Link to comment Share on other sites More sharing options...
western Posted July 23, 2016 Share Posted July 23, 2016 Was going to mention it could be loctited on the crank, Pat beat me to it. Quote Link to comment Share on other sites More sharing options...
DC_ Posted July 24, 2016 Author Share Posted July 24, 2016 Ok think we're Gona try the heat method, thinking of putting a wet rag round the back of the dumbbell at the shaft to maybe help protect it it a little whilst heat is applied to the Pulley. Here's a few pics from yesterday...... As you can see, the coolant wasn't looking great (if there was any coolant at all !! Here's the culprit... The bolt we got from another 2.5 round the back of the shed from a transplant a few years ago on the mates 90. He's got the 200 TDI in it now (lucky sod) This is the set up as we left it.... So I'll let you know how it goes today ! Quote Link to comment Share on other sites More sharing options...
Paddy Posted July 24, 2016 Share Posted July 24, 2016 Is Penol readily available in motor factor stores? Sorry I don't know as I'm still using some I borrowed !!. No use to you now, but seems readily available on line from Chemodex and others. Quote Link to comment Share on other sites More sharing options...
ejparrott Posted July 24, 2016 Share Posted July 24, 2016 Proper penetrating oil, like plusgas or something, not WD40. You need the proper puller that uses the four tapped holes too. Quote Link to comment Share on other sites More sharing options...
ericobrave Posted July 24, 2016 Share Posted July 24, 2016 Why are the four bolts still in ? 1 Quote Link to comment Share on other sites More sharing options...
western Posted July 24, 2016 Share Posted July 24, 2016 The 4 bolts just secure the metal vee belt pulley to the damper part Quote Link to comment Share on other sites More sharing options...
DC_ Posted July 24, 2016 Author Share Posted July 24, 2016 The bolts aren't in they're out. Just not shown in the pics. So, in theory can we use four longer bolts through the vee pulley to the damper on the puller set?? If they're just holding them altogether there wouldn't be much point in using the four holes??

steve b Posted July 24, 2016 Share Posted July 24, 2016 Yes , you should using them as that is the solid hub that I mentioned , it only holds the pulley to the hub so remove bolts and pulley cheers Steveb 1 Quote Link to comment Share on other sites More sharing options...
DC_ Posted July 24, 2016 Author Share Posted July 24, 2016 So if we put the longer bolts in the four holes, then attach the puller set to these bolts, it should in theory still work? Quote Link to comment Share on other sites More sharing options...
DC_ Posted July 24, 2016 Author Share Posted July 24, 2016 So use the longer bolts in those four holes? I'll be using our other pulley then with that set up..... Quote Link to comment Share on other sites More sharing options...
