70sWagoneers 18 Posted March 4, 2019 Share Posted March 4, 2019 (edited) How do i remove the water pump from the timing chain/gear drive of a lycoming 2H? Do you pull the pulley off the front? Do i need to remove the front cover? If so Ive got to remove the radiator. Thanks James C Edited March 4, 2019 by 70sWagoneers (see edit history) Link to post Share on other sites
dictator27 170 Posted March 4, 2019 Share Posted March 4, 2019 Not an expert on Lycoming engines, but I think the radiator needs to come out. Link to post Share on other sites
70sWagoneers 18 Posted March 4, 2019 Author Share Posted March 4, 2019 And then what? I'm looking for all the direction I can get. Haven't worked on a engine like this before. Also I need new gland nuts... who is a good source for water pump parts? Thanks James C Link to post Share on other sites
70sWagoneers 18 Posted March 4, 2019 Author Share Posted March 4, 2019 (edited) Found this pic of a lycoming cut-away engine. So that gear has to come off. Edited March 4, 2019 by 70sWagoneers (see edit history) Link to post Share on other sites
edinmass 12,760 Posted March 4, 2019 Share Posted March 4, 2019 (edited) Water pumps were high service items with packings back in the day, I doubt the radiator would need to be removed if the entire set up is in its stock configuration. That being said, who knows what modifications have been done over the years. What is the vehicle the engine is in? Lycoming was installed in lots of different applications.

Bud Tierney 122 Posted March 4, 2019 Share Posted March 4, 2019 (edited) 2Hs were used by Auburn, Elcar, Gardner and others (for which I don't recall any Clubs/websites)...I believe there're clubs/groups/sites for those three that might be helpful for this or other questions that might come up... OOPS---Apperson also used the 2H... Edited March 4, 2019 by Bud Tierney Addition (see edit history) Link to post Share on other sites
HarryLime 112 Posted March 4, 2019 Share Posted March 4, 2019 That cutaway engine picture isn't the same engine version you show in the top images. How is it your waterpump is there, but your nuts are gone ? Certainly seem too strange. Link to post Share on other sites
nickelroadster 214 Posted March 5, 2019 Share Posted March 5, 2019 In an answer to EDINMASS My 1915 Olds doesn't have to have the radiator removed to take the water pump off but it is easier to do things that way. The crank hole cover and extension is removed and then the front timing cover has to come off (after draining the oil ). One of the timing gears is removed and the water pump is disconnected from the starter-generator- distributor. All you have to do then is disconnect the water pump. I suspect that the Lycoming water pump is just about the same, frequently serviced or not. Link to post Share on other sites
prewar40 25 Posted March 5, 2019 Share Posted March 5, 2019 Check the 'tech aids and tips' page at gardnermotorcars.com there is a 28 page book on Lycoming series H. Not much on water pumps but it might be worth printing anyway. I look every year at Hershey for a Lycoming manual ah maybe next year I'll find one. What car do you have with the 2H engine?

70sWagoneers 18 Posted March 5, 2019 Author Share Posted March 5, 2019 It is a orphan called a Worldmobile. It never went into production. Some say they were working on eight of them but this is the only one left. It has been pushed around for a long time but now the goal is to make it drivable AND preserve as much patina as possible. It is a survivor. But the water pump leaks like a seive and both gland nut are shattered and galled into their holes. So I also need some leads on where to get replacement gland nuts. Ill get size and thread count once i get the pump off. Thanks James C Link to post Share on other sites
1937-44 283 Posted March 5, 2019 Share Posted March 5, 2019 The Napa store in Fremont Ohio might be able to help you out. They did the water pump on my Lycoming Gu engine. Basically they made a new shaft, installed modern bearings and seal, and new nut that looks correct but I no longer have to tighten for the packing. Link to post Share on other sites
Bud Tierney 122 Posted March 6, 2019 Share Posted March 6, 2019 Std Cat is certainly unkiind, citing "unworthiness" per dated styling and a poorly formed hood.. Or did they actually mean "unworldiness"... Link to post Share on other sites
70sWagoneers 18 Posted March 7, 2019 Author Share Posted March 7, 2019 Just spent the last ten minutes lookimg for my copy of that book. Couldnt find it! I think the Standard Catalog is the solitary reference left of the Worldmobile. But that description is spot on with the hood. The coach work is good except the hood. It almost looks like its from another car and then someone bashed it in to match some cowl contours. A lot of the ancilliary parts are sort of propped up and lashed on. It was definitely a prototype made of a conglomerate of different brand pieces. But, I separated the water pump which took days filled with evaporust, razor blades hammered along the parting line, heat, and hammering. Thanks James C Link to post Share on other sites
